By default, learning is enabled and the destination port learns MAC addresses from incoming packets that the port receives. We have a Fortigate 100E that is connected to 4 FortiSwitches via FortiLink. A destination port cannot be an EtherChannel group. With these versions, only one SPAN session is possible. Check the respective release notes or configuration guide to see if you can use RSPAN on the switch that you deploy. When a hub receives a packet on one port, the hub sends out a copy of that packet on all ports except on the one where the hub received the packet. This option appears in CatOS 4.2. learning enable/disable This option allows you to disable learning on the destination port. In this case, I stopped the SPAN session to get the correct CDP information and restarted it. You must create this VLAN. If you select none, the port only receives traffic. Catalyst 5500/5000 does not support the filter option that is available with the set span command. The Catalyst 2950 and 3550 Switches can forward traffic on a destination SPAN port in Cisco IOS Software Release 12.1(13)EA1 and later. Start the sniffer and you should be capturing traffic from the physical port, 1. Simply list all the ports on which you want to implement the SPAN, and separate the ports with commas. Each single packet that a core switch receives on VLAN 1 is duplicated on the SPAN port and forwarded upward to the hub. The total number of active sessions depends on your configuration. Aha, nevermind. This process is known as port-based mirroring and is typically used for external analysis and capture. This time, use Fa0/4 as a destination SPAN port: Issue a show running command, or use the show port monitor command in order to check the configuration: Note: The Catalyst 2900XL and 3500XL do not support SPAN in the Rx direction only (Rx SPAN or ingress SPAN) or in the Tx direction only (Tx SPAN or egress SPAN). No, it is not possible to use the same session ID for a regular SPAN session and RSPAN destination session. The Catalyst 2970, 3560, and 3750 Switches do not require the configuration of a reflector port when you configure an RSPAN session. How are others doing it? Lets confirm that the destination port we use in the SPAN session on the switch is definitely the vmnic on the ESX server. This congestion can affect traffic forwarding on one or more of the source ports. You can specify several VLANs with this filter option. In the menu on the left, select Networking. The VLAN that is monitored is the one that is associated with the static-access port. The main restriction is that all the ports that relate to a particular session (whether source or destination) must belong to the same VLAN. Connect and share knowledge within a single location that is structured and easy to search. Reflector Port A port that copies packets onto an RSPAN VLAN. Your email address will not be published. This could affect traffic forwarding on one or more of the source ports. This document is not intended to be an alternate configuration guide for the SPAN feature. Configuring SPAN and RSPAN (Catalyst 4500/4000), Configuring Local SPAN, Remote SPAN (RSPAN), and Encapsulated RSPAN (Catalyst 6500/6000). Always specify the destination port after the SPAN source. 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. 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. Click any interface where you plan to connect the PC in order to capture the sniffer traces. VLAN membership changes are disallowed on monitor ports and ports that are monitored. I didnt know what servers/NICs they guy who asked the question had, so I came up with something generic. For switch models 124D, 124D-POE, 224D-FPOE, 248D, 248D-POE, 248D-FPOE, 224E, 224E-POE, 248E-POE, 248E-FPOE, 424D, 424D-POE, 424D-FPOE, 448D, 448D-POE, and 448D-FPOE: For access control lists, you can use a mirror destination that does not have src-ingress or src-egress configured or a mirror destination that has src-ingress or src-egress configured. rev2023.3.1.43269. Its not particularly elegant, but it works so I though Id knock up a quick blog post as it might help someone else trying to get this working. Configuration Through the CLI. In the example in this section, the packet is to be transmitted to two different ports, so the counter initializes to 2. 3. All rights reserved. 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.. 3. Your email address will not be published. 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. NAT/Route mode Has 90% of ice around Antarctica disappeared in less than a decade? 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. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Install Wireshark (yum -y install wireshark and yum -y install wireshark-gnome) 1 Answer. Fortinet multiple WAN IP to several ports, Fortigate 100d 802.3ad bonding / Link aggregation, Issues with DMZ on Fortigate 90D, second router can't reach internet. This feature appears in CatOS 5.2 on the Catalyst 4500/4000 and 5500/5000, and in CatOS 5.3 on the Catalyst 6500/6000. Planned Maintenance scheduled March 2nd, 2023 at 01:00 AM UTC (March 1st, 10GbE sfp+ cross over cable required? You cannot convert an existing VLAN into an RSPAN VLAN. The port captures traffic that is software-routed or directed to the MSFC. 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. The packet structure in the PDT is now updated with a reference to the virtual path and counter. The command is: Because there can only be one destination port per session, the destination port identifies a session. Therefore, this feature is relatively easy to understand. In this architecture, a packet that is destined for multiple destinations is stored in memory until all copies are forwarded. Issue thesnoop command in order to set up port-based traffic mirroring, or snooping. Press J to jump to the feed. Any port configured as a src-ingress or src-egress port in one mirror cannot be configured as a destination port in another mirror. A destination port cannot be a source port. Let us know. If you do not specify the encapsulation keyword, the packets are sent untagged, which is the default in Cisco IOS Software Release 12.1(11)EA1 and later. With Cisco IOS Software Release 12.2(33)SXH and later, an EtherChannel can be a SPAN destination. How does a fan in a turbofan engine suck air in? This value is used to find the Virtual Path Index (VPI) of a path structure in the Virtual Path Table (VPT). Always set the destination port before setting the src-ingress or src-egress ports. Your email address will not be published. A destination port in one SPAN session cannot be a destination port for a second SPAN session. This feature is available on the Catalyst 5500/5000 and 6500/6000 Switches, code version CatOS 5.1 or later. You use several command lines in order to configure the source and the destination with RSPAN. Many thanks if someone can point me in the direction of how to set this up on FortiOS/FortiGate. ), Ive probably got this covered elsewhere on the site, but the core switch is Cisco so I just created a trunk port, and allowed ALL VLANs, (because Im lazy, in production, you might want to lock that down a little!). By default the system may have a hardware switch interface called LAN. It does, so we have a working SPAN Session. fairport electric billing. Dedicate 1 port on each FortiSwitch to be the destination port that all links to the analyzer? Add a port group to the vSwitch call it SPAN Target to make it obvious what it is for If you think that a device sends corrupted packets, you can choose to put the sending host and the sniffer device on a hub. The SPAN feature is supported on the Catalyst 4500/4000 and Catalyst 6500/6000 Series Switches that run Cisco IOS system software. It can be any port type, such as EtherChannel, Fast Ethernet, Gigabit Ethernet, and so forth. When you monitor a trunk port as a source port, all VLANs active on the trunk are monitored by default. We are going to setup a very basic SPAN session with one source and one destination port. Note: From Cisco IOS Software Release 12.2(33)SXH and later, PortChannel interface can be a destination port. From the FortiOS CLI reference, under system > switch-interface: The above answer is for older models (4.0). 1 The Catalyst 2940 Switches only support local SPAN. To set up the IPSec VPN, configurations of Network, Router and VPN are required on FortiGate. 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. This diagram is a high-level overview of the path of a packet through the switch. Does Cast a Spell make you a spellcaster? You cannot use filter VLANs in the same session with VLAN sources. You can use normal SPAN in 6.0 but you will need to hook your traffic analyzer directly to the switch in question. end. 2. 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. This will SPAN ports 5/1 through 5/5. On the Catalyst 4500/4000, 5500/5000, and 6500/6000 Switches with CatOS 5.1 and later, you can have several concurrent SPAN sessions. The FortiGate doesn't care which protocol is running over the port 443, so you just need to create a policy and select the corresponding interfaces/addresses and as service you can select HTTPS. The original traffic is unaffected. This issue occurs due to a limitation in the packet forwarding architecture of the switch. So, lets test it. Server Fault is a question and answer site for system and network administrators. Therefore, there is no impact on the switch operation. Incoming traffic is accepted and switched, with untagged packets classified into VLAN 7. I just finished doing this for the same reason for my locations. The default Fortinet Fortigate port number is 443. Each local SPAN session or RSPAN destination session must have a destination port (also called a monitoring port) that receives a copy of traffic from the source ports and VLANs. Configure a new Standard vSwitch specifically for the SPAN target In this case, you can end up in a catastrophic bridging loop condition because STP no longer protects you. If the bandwidth of the reflector port is not sufficient for the traffic volume from the corresponding source ports, the excess packets are dropped. When the index reaches 0, the shared memory can be released. 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. Select the destination port to which the mirrored traffic is sent. 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. Dealing with hard questions during a software developer interview. Also, make sure that no Layer 3 device is present in path of session source to session destination. Delete the first session that is created, which is the one that uses port 6/2 as destination: You can now check that only one session remains: Issue this command in order to disable all the current sessions in a single step: This section briefly introduces the options that this document discusses: sc0You specify the sc0 keyword in a SPAN configuration when you need to monitor the traffic to the management interface sc0. This issue is also documented in Cisco bug IDCSCdy57506(registered customers only). Required fields are marked *. 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.) The monitoring port receives copies of transmitted and received traffic for all monitored ports. 6. The SPAN destination port does not perform any check to verify the source of the packets. You cannot mix source VLANs and filter VLANs within a session. With some FortiSwitch models, you can configure multiple mirror destination ports with the following guidelines and restrictions: These restrictions apply to active mirrors. Error : % Session 2 used by service module, SPAN Session is Always Used With an FWSM in the Catalyst 6500 Chassis. 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". Standard port spanning allows you to mirror one or more physical source ports or VLANs to one or more destination ports, but it does not allow you to set the target to a remote IP Address or a vSwitch. See the Why Does the SPAN Session Create a Bridging Loop? This list provides some restrictions. A monitor port is a destination SPAN port in Catalyst 2900XL/3500XL terminology.
