I have a Nortel Baystack 5510-48T (firmware says Avaya, but hardware says Nortel Networks). I currently have three different VLANs:
VLAN1 - management VLAN and also a VLAN, connected to a Cisco providing Internet access on a gigabit drop, that has all my Internet-facing NICs plugged into; is physically connected into VLAN2 so that LAN IPs can access its management telnet/web service;
VLAN2 - internal network LAN (10.0.0.x);
VLAN3 - Connected to a secondary gigabit drop, has VPN device plugged into it as VPN is on another IP block/circuit, with the VPN device also having a ethernet cable plugged from it into the VLAN2 network.
Right now I physically have the management network physically plugged into via an ethernet cable the LAN so that I can access it from the LAN (and by way of VPN).
What I want to do is make it to where the management port, port #1, is on its own VLAN (the management VLAN) but also is a member of the LAN VLAN (VLAN #2). It currently has a LAN IP address (10.0.0.254) and, again, is physically connected to the a LAN VLAN (VLAN #2) port. Is there a way to have a single port be a member of two VLANs? I know I could set it to where my management network is also the same as the LAN VLAN (VLAN #2), but I'm sure there must be some way to have a single port belong to more than one VLAN.
What can I do? I have full CLI access and am not afraid to use it.
