Adding a vlan to a trunk in Nexus 5K config-sync

Hello

I am trying to add a vlan to a vpc peer-link via the config-sync but I receive the following error "Following commands failed command length checks:" which I can not found in the Cisco documentation.

Does anybody know is there a limitation for the lengh of the "switchport trunk allowed vlan add" comand ? If yes, what the limit is ?

Regards

Lucas

Correct, I was wrong when I stated this was a bug, but is more of a limitation. Yes anything more than 256 would need to be configured inside of 'conf t'

It seems you are hitting CSCtk53795.

Config-sync fails to check if the command length exceeds 256 bytes

Symptom:
Commands longer than 256 characters are not supported in a switch-profile.

Condition:
Always.

Workaround:
None. These commands cannot be synchronized and should be configured in "config
term" mode.

Hello

Thank you for your answer.

The strange thing is that this bug has a status Terminated, without the information in which release the bug is fixed.

As I understand this is not a bug but more a limitation.

So If I need more than 256 characters input, I should not use the config-sync which the recommended method of configuring the pair of Nexus 5k with vCP.

Do I understand it correctly?
