We’ve just begun the transition from our old 3Com switches to new Cisco switches and we’ve encountered interoperability problems as we start the transition.
Goal: Extend 6 VLANs (each representing an IP subnet) via fiber from a port on the 3Com 5500G-EI to a port on the Cisco SG-300-52
Additional information:
Does anyone have any suggestions as to how I can proceed to a) have the management IP address in the IP subnet defined on VLAN 7 while passing the other VLANs to access ports on the Cisco? BTW, I’m a networking neophyte (it’s a very small part of my job and I do it infrequently), so I prefer to use GUI management to CLI options, although I can perform CLI configuration if presented with the right commands.
Thanks in advance for any suggestions. I’ve got a major summer project on hold until this is completed (I’ve got 3 of the Cisco SG-300s that need to be configured and attached to the central 3Com fiber switch).

Hello Raymond,
The switch has a management VLAN configuration option. You may achieve setting the VLAN 7 as the management VLAN on the IPv4 Interface
Administration > Management Interface > IPv4 Interface
Ensure that when you change the management VLAN to a different VLAN that you associate a port to the VLAN 7 as 7untagged, otherwise you will no longer have access to the switch.
