Layer 2 Troubleshooting
Layer 2 (L2) Troubleshooting
VLAN configuration provides network isolation beyond the physical ports. By default, when creating VLANs, they are assigned to all physical ports. This default behavior can be changed when creating a VLAN (assigned to no ports or a subset of ports). Also, all the physical ports of the switch are in “trunk” mode, meaning they are expecting packets to be tagged (802.1Q), and they can process traffic from any VLAN (tagged packet).
If traffic is not getting through to its destination, confirm the VLAN configuration.
Spanning Tree
To build a loop-free topology, switches (“bridges”) must determine the root bridge and compute the port roles, root, designated, or blocked. We highly recommend using RSTP for ad hoc networks that inter-operate in a heterogeneous, multi-vendor switch environment.
RSTP is enabled on the switch by default on Arista NetVisor OS Switches.
CLI Usage Note
To execute command on a local switch only, use the command: switch-local. The display of an asterisk * denotes commands will run on the local switch. To revert to displaying information from all switches use the command: switch.
In some cases, a command's horizontal output may be wide and wrap inside the terminal CLI session. To display the information in a vertical format use the format command layout vertical. To revert, omit the format command.

To display the STP state, use the following command: stp-state-show (data illustrated below is limited to a single VLAN for display purposes)

Additional Troubleshooting Information for STP
The following illustrates an example of the tech-support command output for stp-show.
Note: The factory shipped STP is always RSTP. This configuration setting is a potential user issue during RMA or expansion when adding new nodes to the fabric in the future.

VLAN Status
Verify VLAN status with the command: vlan-show
|
CLI (network-admin@udev-leo1*) > vlan-show id 1 id type auto-vxlan replicators scope description active stats ports untagged-ports active-edge-ports -- ------ ---------- ----------- ----- ----------- ------ ----- -------------- -------------- ----------------- 1 public no none local default-1 yes yes 3,5-72,272-274 3,5-69,272-274 69,273 |
This command will show the relationship between the VLAN and the ports that allow that VLANs traffic. If traffic is not getting through to its destination confirm the VLAN configuration.
Port and VLAN Relationship
Verify port and VLAN relationship with the command: port-show vlan ID

CLI (network-admin@udev-leo1*) > port-show vlan 1 port ip mac vlan hostname status config ---- ----------- ----------------- ---- --------- ------------------------------------ ----------- 69 10.10.10.10 66:0e:94:1b:e5:80 1 udev-leo1 up,PN-internal,stp-edge-port,vlan-up fd,1g,jumbo 69 6.6.6.210 66:0e:94:1b:d0:35 1 udev-leo1 up,PN-internal,stp-edge-port,vlan-up fd,1g,jumbo |
Similar to the VLAN status command, this command will show the relationship between the VLAN and the ports that allow that VLAN traffic.
VLAN Assignment per Port
Verify VLAN assignment per port with the command: port-vlan-show ports ##

CLI (network-admin@udev-leo1*) > port-vlan-show ports 43 port vlans untagged-vlan description active-vlans ---- ---------------------- ------------- ----------- ------------ 43 1,31,90,1111,1311,1411 1 none |
Similar to the VLAN status command, this command will show the relationship between the VLAN and the ports that allow that VLAN traffic.
Monitoring and tracking a specific MAC address with the L2 table within the fabric is a powerful troubleshooting tool. MAC address and port relationship is also an important troubleshooting tool.
Beyond the L2 table, the Pluribus switch also creates and tracks vPorts. vPorts provide a fabric wide view on MAC addresses and their relationship to VLANs and other critical information.
