3com Baseline inter-switch vlan database
Posted on 2011-10-19
3 - 3com BaseLine 2952-SFP Plus
Setup - We have 3 Baseline 2952 switches. All switches are connected to each other via ports 47 and 48 which are configured as TRUNK ports.
Most of our equipment resides on the default VLAN1. We have configured a new VLAN (5) and made ports 20-22 on switch 1 access ports on vlan 5. This works fine, equipment plugged into those ports can talk to each other with no problem. The problem is trying use port 8 on switch 2 in vlan 5. If I make that port an access port on VLAN5, the computer cannot communicate with objects on switch 1 ports 20-22.
I do not have these switches in stacking mode, as I thought the trunk ports should allow sharing of the VLAN databases based on dot1q.
My question is, do I need to enable stacking and make ports 47 and 48 stack ports to share the vlan database?
NOTE: I am not trying to route between vlans. Simply share vlans across switches
