suppose i have cw LMS connected to a L2 switch. this sw has int vlan 1 shutdown and an IP address in vlan2. cw has an IP in same subnet as int VLAN 2.
v3 exists also in the switch.
can cw/lms track computers in vlan 2 and 3? ie: can we obtain the list of computers attached in each port in this switch?
This will not work. The PIX, FWSM, and ASA devices are not supported by Campus Manager, and will not work as routers for UT. What you could do is put another, supported router on the same subnet, and have it act as the default gateway, but simply redirect hosts to the PIX. This device would cache ARP entries, and would allow UT to show MAC addresses with IPs. This is what I do in my lab, and it works quite well.
Say a switch has it's management interface in VLAN 2. However, you have access ports on that switch in VLAN 3. User Tracking will walk the BRIDGE-MIB for each VLAN on the switch, and get all connected MAC addresses. It will then query all routers which have interfaces in those same VLANs (i.e. VLANs 2 and 3). It will pull the ARP table from each router, then match the MAC addresses from the ARP table entries up with the MAC addresses from the BRIDGE-MIB entries.
Therefore, each router on every subnet must be managed bu Campus Manager in order for User Tracking to map MAC addresses to IP addresses.
