I have an existing FAS8020 running cDOT 8.3GA that has ifgrp a0a configured based on e0c and e0d. It is on 192.168.87.0/24 subnet and there is no VLAN currently. I need to implement a new VLAN 192.168.89.0/24 but I don't have other 10GbE ports for this so the only way I can think of is to create a VLAN on top of a0a. Does it make sense?
If so, will this interrupt the existing 192.168.87.0/24 traffic?
Also it looks like I need to create a broadcast domain, e.g.?
network port broadcast-domain create -broadcast-domain bcast89 -mtu 1500 -ports node1:a0a,node2:a0a
I also need to create a IPspace for 192.168.89.0/24 and associate with the above broadcast domain even though I only asign IP statically?

Thanks for the reply. However, I see in cDOT 8.3 Network Management Guide, p25, it states:
"When you configure a VLAN over a port for the first time, the port might go down, resulting in a
temporary disconnection of the network.
Subsequent VLAN additions to the same port do not affect the port state"
Is the above true? In my case, I need to create a VLAN on top of an ifgrp with multimode_lacp and I have live traffic on the underlying ifgrp, will it actually interrupt the traffic on the ifgrp?

Just move the lif(s) on a0a to another node before you add the VLAN to a0a. Once the vlan is in place, has a lif on it and has been tested, repeat the process for the other node(s). When all the nodes are done send all the lifs home.
