NOT ABLE TO ADD VLAN TO PORT PROFILE

[mohit.pathak2000]

Dear Friends, 

I am looking for a help about the VLAN addition to a existing port profile. 

I have to add vlans to existing port profile. Vlans exists on switch. But when I add the vlan I get error "Failed to write VSH commands".

Below is the snippet of the configuration.

Could you please help me on how to get rid of the error. 

Thank you for your help in advance.

Hi Mohit,

Seems to be problem with VSH shell. It will parse the command and give to right component. Here the problem seems to be with parsing. you can try to create a new VSH through the below command in deplugin shell and try the same thing.

Steps to create:

1) load the dbplugin image and login into linux shell

2) /isan/bin/vsh

3) then try configuring the port-profile

If not, as a workaround, you can delete and recreate the port-profile i might help u.

Are you facing problem only with adding the vlan or any commands ?

Thanks,

Muthu.

Hello Mohit,

NOT ABLE TO ADD VLAN TO PORT PROFILE
Learn whether some non-existing FEX ports are part of a port-profile, which are causing
the trouble. We can make use of  for the
same. Once we know such FEX ports, we can pre-provision the corresponding FEX and thus un-inherit
the port-profile from these ports. Now, we can make changes in the port-profile config.

An ancient thread I know, but as I came a cropper with the same issue I think it is worth adding that the solution for me when I had this problem was to add the 'switchport' command, this needs to come at the top of the config attributes - ie before 'switchport mode...' and 'switchport access vlan ...'.

switchport

switchport mode access

switchport access vlan ...
