ACI Interface Trunk

[Guilherme Gianotto Bratfisch]

Hello,

Some EPGs that are configured stactically for trunking in a correspondent vlan are not showing as allowed on the interface, even if the layer2 communication works.

I'm new to the aci world but is this a desirable state ?

Here the config on the leaf and the picture of the config in ACI

-----------------------------------------------------------------------------------
 Port           Vlans Allowed on Trunk                                             
-----------------------------------------------------------------------------------
 Po2            8,10-11,13,25,27,39,41,82,84,87,89,110

Thanks in advance

If you're looking at that command output from the CLI of a Leaf, then you're likely looking at the locally significant (aka system VLAN) VLAN ID (not the wire-encap VLANs denoted by your EPG static path config.

The better command to look at this output is "show vlan extended".  This will show you the system VLAN (first column) as well as the EPG/BD name and then the encap VLAN.  Once you match up the encap VLAN with the System VLAN, the output above will make sense.
