Rename VLANs on LTM

We planning to rename one of the VLAN on F5 LTM, whether is possible to delete completely and recreate again?   Or any other recommendations?   I don't want to reload this box.

Hi,

You can do this :

  1. create new VLAN
  2. modify self-ip to new VLAN
  3. delete old VLAN
  4. change VLAN properties to assign interface.

with tmsh commands:

create net vlan new tag 1111
modify net self self_net_ad_ipv6 vlan new
delete net vlan old
modify net vlan new interfaces replace-all-with { 1.3 { untagged } } tag 1234
