Hello,

Is it possible to somehow choose the name of VLANs that are dynmically assigned by Control? I am using FA and control to assign the VLANs and the VLAN will always be named SYS_VLAN_Number. If I am using different VLANs for voice per stack, I would like those to be named VOICE on the stack, so if push lldp med policy commands, I just have to specificy the vlan name “VOICE”?

Thanks.

Hi all,

created a simple script for setting the correct names on FA vlan’s. In the script you can give the ip address of the source/uplink switch. The script queries the local switch and queries the XMC data for the vlans of the uplink switch and changes the name of the vlans if they are not the same as the source/uplink switch.

Thought I shared it with you all

Planning to run this script two times a day to my switches. Or do you see away to run it after a vlan is added to the switch via fa ?

Kind regards

Jay,

What is the target platform?
