Vlan Change
Hi Experts,
A vlan is deployed but with incorrect mask. Vlan has many virtuals,pools etc configured. Mask needs to be corrected.
Is there a way to correct the mask without removing the complete vlan and related configuration and redeploying it?

You can change any relevant Self-IPs in the GUI via Network > Self IPs

Hi,
here is how you can do it via tmsh:
root(tmos) create net self 10.10.10.10 address 10.10.10.10/24 vlan vlan-0010 root(tmos) list net self 10.10.10.10 net self 10.10.10.10 { address 10.10.10.10/24 traffic-group traffic-group-local-only vlan vlan-0010 } root(tmos) load sys config from-terminal merge Enter configuration. Press CTRL-D to submit or CTRL-C to cancel. net self 10.10.10.10 { address 10.10.10.10/23 traffic-group traffic-group-local-only vlan vlan-0010 } Loading configuration... root(tmos) list net self 10.10.10.10 net self 10.10.10.10 { address 10.10.10.10/23 traffic-group traffic-group-local-only vlan vlan-0010 } root(tmos)Notice mask changes on self address.

Will there be any impact to say, to traffic on other vlans, if done via GUI or tmsh? or if this change needs to be done on a pair of ltm's in HA?

What you are trying to accomplish cannot be done easily. You cannot change an existing self ip, and you cannot delete it since that would leave "orphaned" objects.
You would have to make changes to the bigip.conf and/or bigip_base.conf, and then force mcpd to reload the configuration on a reboot.

Hmm.... Interesting approach zup. I'll have to take a further look at that.

Am I missing something? The mask for a Self IP can easily be changed in the GUI.
