The Switch Port Analyzer (SPAN) feature is now available for hardware switch interfaces on FortiGate models with built-in hardware switches (for example, the FortiGate-100D, 140D, and 200D etc.) The network analyzer can be a Cisco SwitchProbe device or other Remote Monitoring (RMON) probe. 6. Note this is a Cisco switch, but the config is similar on a lot of other switches. Only one destination port is allowed per SPAN session, and the same port cannot be a destination port for multiple SPAN sessions. Add the spare NIC to the vSwitch as an uplink Is there such a thing? Select the destination port to which the mirrored traffic is sent. The port captures traffic that is software-routed or directed to the MSFC. The example uses SPAN on port 6/1 and a range of three ports, from 6/3 to 6/5: Note: There can only be one destination port. Eventually, the set span command allows you to configure a port to monitor local traffic for an entire VLAN. Click Create New to create a new VDOM. Configure the vSwitch to allow promiscuous mode. In this session, port 6/1 to 6/2 is monitored, and at the same time, VLAN 3 to port 6/3 is monitored: Now, issue the show span command in order to determine if you have two sessions at the same time: Additional sessions are created. Solution 2. I just wanted to mention that I'm working on an NMS using a project called. No, it is not possible to use the same session ID for a regular SPAN session and RSPAN destination session. This could affect traffic forwarding on one or more of the source ports. From CLI access to standalone FortiSwitch using SSH/TeraTerm. You can create as many local PSPAN sessions as necessary. The send of the packet to two ports is not an issue because the switching fabric is nonblocking. The following example configuration is valid for FortiSwitch-3032D. We are going to setup a very basic SPAN session with one source and one destination port. Add the rx (receive) or tx (transmit) keyword to the end of the command. Issue the monitor session session_number destination interface interface_id encapsulation dot1q command in order to enable encapsulation of the packets at the destination port. Complete these steps to configure the SPAN: You can download CNA from theDownload Software (registered customers only) page. On the Catalyst 2900XL/3500XL Series Switches, Cisco IOS Software Release 12.0(5)XU is used. 5. This behavior can be desired. The Catalyst 3550, 3560, and 3750 Switches can support up to two SPAN sessions at a time and can monitor source ports as well as VLANs. VLAN filtering applies only to trunk ports or to voice VLAN ports. Other ports and the management interface are configured in the default VLAN 1. For example, you can create PSPAN sessions on the configuration port that you have chosen to be a destination SPAN port. If learning is enabled, the port also transmits traffic directed to hosts that have been learned on the destination port. The impact on the high-speed switching fabric is negligible. With the normal SPAN, how would we go about analyzing all 4 switches? Configuring network interfaces. 2. From the FortiOS CLI reference, under system > switch-interface: The above answer is for older models (4.0). The Switch Port Analyzer (SPAN) feature is now available for hardware switch interfaces on FortiGate models with built-in hardware switches (for example, the FortiGate-100D, 140D, and 200D etc.). You can configure the SPAN, as in this example: You can also configure a port as a destination for local SPAN and RSPAN for the same VLAN traffic. I need to create a copy of all traffic from those switches to a 3rd party traffic analyzer. On the Catalyst 5500/5000 and 6500/6000 Series Switches, a packet that is received on a port is transmitted on the internal switching bus. With use of the SPAN feature, a packet must be sent to two different ports, as in the example in the Architecture Overview section. Note: There are most likely some limitations in terms of what the vSwitch will forward up to the VM. From the article: The Switch Port Analyzer (SPAN) feature is now available for hardware switch interfaces on FortiGate models with built-in hardware switches (for example, the FortiGate-100D, 140D, and 200D etc.) In this example, the session captures all incoming traffic for VLANs 1 and 3 and mirrors the traffic to port 6/2: Trunks are a special case in a switch because they are ports that carry several VLANs. Do EMC test houses typically accept copper foil in EUT? In the diagram in this section, satellite 1 knows that the packet X is to be received by satellites 3 and 4. This feature appears in CatOS 5.3 in the Catalyst 6500/6000 Series Switches and is added in the Catalyst 4500/4000 Series Switches in CatOS 6.3 and later. Error "% Local Session Limit Has Been Exceeded", Cannot Delete a SPAN Session on the VPN Service Module, with the Error "% Session [Session No:] Used by Service Module". A packet structure that points to this buffer is initialized in the Packet Descriptor Table (PDT). The show rspan command gives a summary of the current RSPAN configuration on the switch. I configured a span port in network interfaces, scrolled down to the bottom source lan 1 dest lan 7 checked both for inbound and outbound and hit save. Select from the excluded ports which ports to include for ingress mirroring and egress mirroring. The SPAN or RSPAN source interface in VSPAN is a VLAN ID, and traffic is monitored on all the ports for that VLAN. Configure a new Standard vSwitch on the vSphere host With Cisco IOS Software Release 12.2(33)SXH and later, an EtherChannel can be a SPAN destination. Aha, nevermind. On a given port, only traffic on the monitored VLAN is sent to the destination port. 5. Nevertheless, the connection can be dangerous if you connect the destination port to other networking equipment that creates a loop in the network. For VLAN SPAN sources, all active ports in the source VLAN are included as source ports. Select the destination port to which the mirrored traffic is sent. Next step is to get the sniffer VM setup. It is in point of fact a nice and useful piece of info. He wasnt using Cisco switches either if memory serves. Every line card in the switch starts to store this packet in internal buffers. Create an untagged Port Group called SPAN Target 7. This option appears in CatOS 4.2. learning enable/disable This option allows you to disable learning on the destination port. The Direction: transmit/receive field shows this. If you select another port as the monitor port, the previous monitor port is disabled, and the newly selected port becomes the monitor port. Many thanks if someone can point me in the direction of how to set this up on FortiOS/FortiGate. 2. A destination port cannot be an EtherChannel group. Note: Even when the inpkts option prevents the loop, the configuration that this section shows can cause some problems in the network. This feature is available on the Catalyst 5500/5000 and 6500/6000 Switches, code version CatOS 5.1 or later. The FortiSwitch unit assigns the uplink port and the dst port. error message. The variable snoop_direction is the direction of traffic on the source port or ports that are monitored: receive, transmit, or both. With this limitation in mind, I came up with a solution. 4 x 3 pings = 12 packets and I should also see the replies,so the sniffer should have 24 frames in total in its display buffer. If ports are added to or removed from the source VLANs, the traffic on the source VLAN received by those ports is added to or removed from the sources thaat are monitored. The 100E is running v6.0.4. Configure the vSwitch to allow promiscuous mode As this document states, a port that you configure as the SPAN destination still belongs to its original VLAN. On the Catalyst 2950 Series Switches, you can have only one assigned monitor port at any time. To create a VLAN for the lab go to Network -> Interfaces, then select the interface that the VLAN for the tunnel is going to be and click on Create New. The state of the destination port is up/down by design. Imagine that you want to use SPAN on the traffic in VLAN 2 for ports 6/4 and 6/5. We have received your feedback. However, it does not capture the traffic that flows in the actual VLAN itself. Error : % Session 2 used by service module, SPAN Session is Always Used With an FWSM in the Catalyst 6500 Chassis. Save the configuration. Please deactivate or delete another active session to make room. For example, you can create PSPAN sessions on the configuration port that you have chosen to be a destination SPAN port. Connect the spare NIC to a port on the same switch as the port you want to monitor. Valid characters are A - Z, a - z, 0 - 9, _, and -. # config switch mirror. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. How to enable Cisco switch port mirroring without rebooting? How can I recognize one? SPAN traffic coming from other port types is not affected by VLAN filtering, which means that all VLANs are allowed on other ports. spanning port 15/1On the Catalyst 6500/6000, you can use port 15/1 (or 16/1) as a SPAN source. Thanks for the post. The port does not transmit any traffic except that traffic required for the SPAN session unless learning is enabled. Egress mirroring of virtual wire ports will have an additional VLAN header on all mirrored traffic. If you configure the VLAN interface with an IP address, then the port monitor command monitors traffic destined to that IP address only. Unicast flooding occurs when the switch does not have the destination MAC in its content-addressable memory (CAM) table. Network problems can occur because of MAC address learning issues that are associated with learning enabled on the destination port. The monitoring port receives copies of transmitted and received traffic for all monitored ports. Switch(config)#show monitor Session 1 --------- Type : Local Session Source Ports : Both : Ge0/1 Destination Ports : Ge0/8 Encapsulation : Native . See the Create Several Simultaneous Sessions and Feature Summary and Limitations sections of this document. The above answer is for older models (4.0). Here, the mirrored ports are assigned to VLANs 1, 2, and 3. Network. Learn more about how Cisco is using Inclusive Language. If you have a multicast source that generates a multicast stream from behind the FWSM, you need the SPAN reflector. Another possibility is to use SPAN on the entire VLAN 2: With this configuration, at least, you only monitor traffic that belongs to VLAN 2 from the trunk. Flutter change focus color and icon color but not works. This discard protects the port from bridging loops. Any thoughts? As a business we are heading towards Forti, but before I said yes I wanted to know what the firewall was actually doing before I said yes. FortiGate Port ForwardingLets create Port forwarding on our FortiGate firewall and map 2 web servers to one IP address - An NSE4 trainingMy Books-----. The action often occurs because of a typographical error, for example, if the user wants to enable STP. Spanning tree is automatically disabled on a reflector port. The VLAN that is monitored is the one that is associated with the static-access port. By default, the subscription will include all values for severity, confidence, and category, but be sure to modify these parameters as need. Network Analyzer/Security Device Connected to SPAN Destination Port is Not Reachable, Local SPAN, RSPAN, and ERSPAN Destinations, Getting Started Guide for the Catalyst Express 500 Switches 12.2(25)FY, Getting Started Guide for the Catalyst Express 520 Switches, Release Notes for Catalyst 2948G-L3 and Catalyst 4908G-L3 for Cisco IOS Release 12.0(10)W5(18g), SPAN on the Catalyst 2940, 2950, 2955, 2960, 2970, 3550, 3560, 3560E, 3750, and 3750E Series Switches, Local SPAN, RSPAN, and ERSPAN Session Limits, Configuring Local SPAN, Remote SPAN (RSPAN), and Encapsulated RSPAN, Configuring Local SPAN, RSPAN, and ERSPAN, Configuring Local SPAN, Remote SPAN (RSPAN), and Encapsulated RSPAN - Catalyst 6500 Series Cisco IOS Software Configuration Guide, 12.2SX, How to configure SPAN and RSPAN on Cisco Catalyst 4500 switches that run Cisco IOS Software, A SPAN destination port is shown as "not connected" and does not communicate with the rest of the network, Technical Support & Documentation - Cisco Systems, Yes Supervisor 2T with PFC4, Supervisor 720 with PFC3B or PFC3BXL running Cisco IOS Software Release 12.2(18)SXE or later. 6. RSPAN session cannot cross any Layer 3 device as RSPAN is a LAN (Layer 2) feature. The destination port can then be located anywhere in this RSPAN VLAN. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Thanks for sharing this method. I will look into the ERSPAN to see what that is about. Press question mark to learn the rest of the keyboard shortcuts. monitor session 1 source interface Gi1/0/24 You can find it useful to prune this VLAN on such S1-S2 links. There can even be several destination ports. On the top, all the satellites are interconnected via a high-speed notify ring that is dedicated to signaling traffic. In this case, the port I am using as the source is a link between two switches (the one in my study and the switch in the garage where the servers are). Catalyst Express 500/520 ports can be configured for SPAN only by using the Cisco Network Assistant (CNA). Port snooping lets you transparently mirror traffic from one or more source ports to a destination port.". The ERSPAN traffic is sent to a specified IP address, which must be reachable by IPv4 ICMP ping. The switching functionality is enabled on the dst interface when mirroring. For Windows, download from http://www.wireshark.org So I am not sure if the issue is the FortiLink interface and how it interacts with the FortiSwitches or something else. Select Load balancers in the search . Use of this term is avoided in this document. Heres how to set this up: Configure the ESXi Host. The interface shows the port in this state in order to make it evident that the port is currently not usable as a production port. In order to make this determination, a hash value is computed from this information: Class of service (CoS) (either IEEE 802.1p tag or port default). ESPANThis means enhanced SPAN version. Can an RSPAN Session Work Across Different VTP Domains? NOTE: You can use virtual wire ports as ingress and egress mirror sources. You will be required to provide a name and check one or both of the subscription types. Why does awk -F work for most letters, but not for the letter "t"? Find a spare NIC on a vSphere host The port GE0/8 is where the user device is connected. 9. 04-03-2006 10:03 AM. When both ingress and a trunk encapsulation are specified on a SPAN destination port, the port goes forwarding in all active VLANs. Any port configured as a src-ingress or src-egress port in one mirror cannot be configured as a destination port in another mirror. All other marks are the property of their respective owners. The Cisco IOS Software automatically creates a SPAN session for the VPN service module in order to handle the multicast traffic. If it's a policy from internal network to WAN, be sure to select NAT also. Questions or comments on this page's content? Using remote SPAN (RSPAN) or encapsulated RSPAN (ERSPAN) allows you to send the collected packets across layer-2 domains for analysis. Destination EtherChannels do not support the Port Aggregation Control Protocol (PAgP) or Link Aggregation Control Protocol (LACP) EtherChannel protocols; only the on mode is supported, with all EtherChannel protocol support disabled. Add a port group to the vSwitch call it SPAN Target to make it obvious what it is for I should be able to see all traffic on the sniffer that passes across that link. The command is set span source_vlan(s) destination_port . The Admin Source field basically lists all the ports that you have configured for the SPAN session, and the Oper Source field lists the ports that use SPAN. The port as up/down monitoring is normal. Currently, the ERSPAN feature is supported in: Supervisor 720 with PFC3B or PFC3BXL running Cisco IOS Software Release 12.2(18)SXE or later, Supervisor 720 with PFC3A that has hardware version 3.2 or later and running Cisco IOS Software Release 12.2(18)SXE or later. By default, learning is enabled and the destination port learns MAC addresses from incoming packets that the port receives. If ingress traffic forwarding is enabled for a network security device. I suspect this might have something to do with the DefaultVLAN? On FortiSwitch models that support RSPAN and ERSPAN, set the trunk or physical port that will act as a mirror. It can be any port type, such as EtherChannel, Fast Ethernet, Gigabit Ethernet, and so forth. The problem is that now you also receive traffic that you did not want from port 6/3. Thanks for contributing an answer to Server Fault! This feature is available on the Catalyst 5500/5000 and 6500/6000, CatOS 5.1 and later. Choose the source port and select the VLAN you plan to monitor. Using the GUI: Go to Switch > Mirror. If you use a PC as a sniffer, you might want this PC to be fully connected to the VLAN. The Catalyst 2970, 3560, and 3750 Switches do not require the configuration of a reflector port when you configure an RSPAN session. Select Interface. Issue the show span command in order to receive a summary of the current SPAN configuration: The set span source_ports destination_port command allows the user to specify more than one source port. The reflector port loops back untagged traffic to the switch. This example command illustrates that the monitor of a port in a different VLAN is impossible: In order to finish the configuration, configure another session. I found it in the FortiOS CLI reference, under switch-interface > span/span-dest-port/span-direction/span-source-port. This table provides a short summary of the current restrictions on the number of possible SPAN and RSPAN sessions: Refer to Local SPAN, RSPAN, and ERSPAN Session Limits for Catalyst 6500/6000 switches running Cisco IOS software. 2023 Cisco and/or its affiliates. Would the reflected sun's radiation melt ice in LEO? Select the blue Review + create button at the bottom of the page, or select the Review + create tab. Put the TCP and UDP ports of the Fortinet Fortigate server in the boxes in your router. Dealing with hard questions during a software developer interview. At the same time, the Encoded Address Recognition Logic (EARL) receives the header of the packet and computes a result index. Be careful that a port in the monitor state does not run the Spanning Tree Protocol (STP) while the port still belongs to the VLAN of the ports that it mirrors. 1 Answer. The FortiSwitch unit can send a copy of any ingress or egress packet on a port to egress on another port of the same FortiSwitch unit. A 10/100 port reflects at 100 Mbps. Using remote SPAN (RSPAN) or encapsulated RSPAN (ERSPAN) allows you to send the collected packets across layer-2 domains for analysis The Catalyst 4500/4000, 5500/5000, and 6500/6000 Series Switches allow you to collect only egress (outbound) or only ingress (inbound) traffic on a particular port. Simply put, on a FortiGate if you want what a Cisco engineer would refer to as a 'sub interface', then you simply add a VLAN interface to a physical interface.Like so, Network > Interfaces > {Physical Interface} > Create New > Interface. Thats it, you should now be able to see all traffic in and out of the target port on your sniffer. With the issue of theset span enable command, a user reactivates the stored SPAN session. Collaborator. 05:34 PM, The Fortinet Security Fabric brings together the concepts of convergence and consolidation to provide comprehensive cybersecurity protection for all users, devices, and applications and across all network edges.. With this configuration, traffic from SPAN sources associated with session 1 are copied out of interface Fast Ethernet 5/48, with 802.1q encapsulation. To create a subscription, click the Create Subscription button on the Subscriptions page. Whether one or several ports eventually transmit the packet has absolutely no influence on the switch operation. Packets only enter the RSPAN VLAN in switches that are configured as RSPAN source. If the monitoring port is 50 percent oversubscribed for a sustained period of time, the port likely becomes congested and holds part of the shared memory. I exchanged a few tweets about the problem and then had an idea that I tested in the home lab. Select to mirror traffic received, traffic sent, or both. Port Fast Ethernet 0/1 (Fa0/1) monitors traffic that ports Fa0/2 and Fa0/5 send and receive. This port is called a SPAN port. You must create this VLAN. In order to monitor some S1 ports or VLANs from S2, you must set up a dedicated RSPAN VLAN. I added a member to the FortiLink interface and setup port spanning to the analyzer, but it is not receiving any traffic. VM FEX might work here too although I dont know if you can span to a veth (never tried it although a Nexus 5K will take the config!). This information in this document uses CatOS 5.5 as a reference for the Catalyst 4500/4000, 5500/5000, and 6500/6000 Series Switches. Connect a VM running a sniffer to the Port Group 8. See these sections of this document for information about the performance impact for the specified Catalyst platforms: An EtherChannel does not form if one of the ports in the bundle is a SPAN destination port. A destination port has these characteristics: A destination port must reside on the same switch as the source port (for a local SPAN session). Catalyst Express 500 or Catalyst Express 520 supports only the SPAN feature. If no IPaddress is specified, the traffic is not mirrored. The CatOS now has the ability to run several sessions concurrently, so it can have different destination ports at the same time. Server Fault is a question and answer site for system and network administrators. ERSPAN consists of an ERSPAN source session, routable ERSPAN GRE-encapsulated traffic, and an ERSPAN destination session. Apart from this difference, SPAN and RSPAN really behave in the same way. Why does Jesus turn to the Father to forgive in Luke 23:34? VLAN-based SPAN (VSPAN)On a particular switch, the user can choose to monitor all the ports that belong to a particular VLAN in a single command. The main restriction is that all the ports that relate to a particular session (whether source or destination) must belong to the same VLAN. Always specify the destination port after the SPAN source. Use a list of one or more VLANs as a source, instead of a list of ports: With this configuration, every packet that enters or leaves VLAN 2 or 3 is duplicated to port 6/2. To enable SPAN on a hardware switch via the GUI, go to System > Network > Interfaces and edit a hardware switch interface. For newer models (5.0-5.4), look here. set status active. 24h/24 - 7j/7. Required fields are marked *. Therefore, you cannot have two SPAN sessions that use the same destination port. What firmware are you using? I had to span each fortilink interface on the fortiswitch side though to another available fortiswitch port. Ingress trafficTraffic that enters the switch. Reflector Port A port that copies packets onto an RSPAN VLAN. I could do it with a passive network tap, of course; but it seems really strange to me that the 100D doesn't seem to expose an easy way to do this. 8. Therefore, this feature is relatively easy to understand. In this way, all packets that are forwarded to the sniffer are also tagged with their respective VLAN IDs. Making statements based on opinion; back them up with references or personal experience. What are some tools or methods I can purchase to trace a water leak? Note that once you start the SPAN session into the ESX server, that the CDP information on the vSwitch becomes unreliable. DevOps & SysAdmins: Network Tap (SPAN port) on FortiGate 100D (FortiOS 4.0MR3) (2 Solutions!!). If an RSPAN source session is configured with a particular RSPAN VLAN and an RSPAN destination session for that RSPAN VLAN is configured on the same switch, then the RSPAN destination session's destination port will not transmit the captured packets from the RSPAN source session due to hardware limitations. mirror an internal port to a different internal port. It is seeing CDP from other locations and getting confused. Port-based SPAN (PSPAN)The user specifies one or several source ports on the switch and one destination port. When you configure a SPAN session to monitor the port, the destination interface shows the state down (monitoring), by design. SPAN is used for troubleshooting connectivity issues and calculating network utilization and performance, among many others. If a reflector port is oversubscribed, it could become congested. monitor session 1 destination interface Gi1/0/16 (Using Extreme switches). Also, a configuration error can cause the problem. These are guidelines for the configuration of the SPAN feature on the Catalyst 2940, 2950, 2955, 2960, 2970, 3550, 3560, 3560-E, 3750, and 3750-E Series Switches: The Catalyst 2950 Switches can have only one SPAN session active at a time and can monitor only source ports. See the Knowledge Base article on the vendor website to learn more about configuring port mirroring on Fortinet-FortiGate Switches. Therefore, when you consider this architecture, the SPAN feature has no impact on the performance.
