Hi,
So on a recent switch such as the CRS310-8G+2S+IN, assuming I already have some vlans configured on the bridge interface (/interface/bridge/vlan) and that my management vlan is 1, where is it recommended to configure the switch own management IP ?
a) directly on the bridge interface with PVID=1 (/interface/bridge) ?
b) or on a new vlan 1 interface on the switch ? (/interface/vlan) ?
From what I read I think the good answer is b), but why? What kind of issues could arise in assigning an IP to the bridge directly?
Thanks!
Re: management IP on bridge or vlan interface for CRS310 switch [SOLVED]
If you insist that management VLAN resides on VID 1, then it's a). Reason: default config uses VID=1 for all sorts of configuration (e.g. PVID on all ports, including bridge CPU-facing port). It is possible to get it going as tagged (which is where VLAN interfaces come into play), but it's a tedious job because one has to look at all the places where VID=1 might be used in any possible way and do something about it.
Since also other vendors treat VID=1 in special way (and each has slightly different approach at it), I'd recommend to go for a different VID for management. And in that case, it would be option b).
