I have 2 ciso MDS 9513 switches and have ISL enabled between those.I want to restrict 1 VSAN traffic to pass through that ISL,i know i can do it through DM by configuring the port properties to Allow VSAN's,but not sure whether this can be done online without disrupting the traffic of the VSAN which i want to allow..The switches are in production..
appreciate your help in this regards..
Thanks and Regards,
Sure...If you are on the command line, issue this command on the FC or port-channel interface.
swichport trunk allow vsan 22,52
This will remove all other VSANs.
To add a new VSAN (example VSAN 100), the command is
switchport trunk allow vsan add 100
to remove VSAN 22 the command is
no switchport trunk allow vsan 22
The key is not to issue the command
switchport trunk allow vsan 22 (without the add option) as this will set the trunk to only allow vsan 22.
These config commands should be performed on both ends.
Once the trunk is up, you can add/remove vsans with these commands. 'add' must be included when adding a vsan or it will overwrite the current allowed list.
I think with FM, you have the option to type in the VSAN numbers youwant to add as part of teh EISL trunk configuration.
Hope this helps,
