Reviewing Layer 3 peer list statistics
When a MU roams to a current switch on the same layer 3 network, it sends a L2-ROAM message
to the home switch to indicate the MU has roamed within the same VLAN. The old home switch
forwards the information to all its peers. The MU is basically re-synchronized to the new current
switch, but keeps its old IP address. The same procedure is followed, even if the new current switch
is on a different layer 3 subnet, but uses the same VLAN ID (overlapping VLAN scenario).
Tracking these message counts is important to gauge the behavior within the mobility domain.The
Layer 3 Mobility screen contains a tab dedicated to tracking the message sent between the current
switch, home switch and MU.
To view layer 3 peer statistics
1. Select Services > Layer 3 Mobility from the main menu tree.
The Layer 3 Mobility screen appears with the Configuration tab displayed.
