I have 2 BES-53248 switches clustered using Netapps BES-53248-RCF-v1.8-Cluster config. Prior to installing this config I was able to change the default vlan from 1 to 999 as part of security stigs I need to apply. After running the config I can no long change that setting or at least when I run
(cs01)(Interface 0/1)#vlan pvid 999
I do see 999 applied to the running config but when I run
(cs01)#show vlan port all
0/1 Port vlan ID configured and current are both vlan 1 .
Any thoughts? I have a felling it has something to do with the clustering, but I just don't know enough about these switches to speak to it.
A1: VLANs 17 and 18 are used for HA traffic on AFF/FAS platforms that use a shared cluster+HA Ethernet ports (AFF A320, AFF A250, FAS500f). Please do not change anything related to VLANs 17 and 18.
A2: The ISL ports 0/55 and 0/56 normally ONLY span VLAN 1 (default VLAN). You should NOT be spanning VLAN 17/18 (this is by design). Now with VLAN 999 being used natively for cluster traffic, I would go with this config: switchport trunk allowed vlan 1,999
I believe VLAN 1 is still used for some control traffic (e.g. CDP/ISDP), so that's why I'm keeping VLAN 1 in there. But you can remove it and see what happens 🙂
