Hi,

I newbie in Arista

 

My problem is that when I run show mlar config-sanity it returns this error
#show mlag config-sanity
No per interface configuration inconsistencies found.

Global configuration inconsistencies:
Feature Attribute Local value Peer value
————- ——————— —————- – ———-
stp 3 disabled-vlan True –

Which may be due?

I think everything is correctly configured but…..

 

Please help me

Hello Juan,

show mlag config-sanity displays what configuration attributes are inconsistent.

show mlag config-sanity all displays all configuration attributes ( consistent and inconsistent ) compared with respect to the peer configuration

You can go through the EOS article below

Hi Juan,

Based on the snippet provided, it looks like the spanning-tree instance has been disabled for VLAN 3 on the switch where the o/p was run as Local Value is true and STP for VLAN 3 is still enabled on its MLAG peer.

Eg:

 

switch1#sh run sec spanning
spanning-tree mode mstp
no spanning-tree vlan 100,4090

 

 

swicth2#sh run sec spanning
spanning-tree mode mstp
no spanning-tree vlan 4090

 

switch1#show mlag config-sanity
No per interface configuration inconsistencies found.

Global configuration inconsistencies:
Feature Attribute Local value Peer value
------------- ----------------------- ----------------- ----------
stp 100 disabled-vlan True -
