3. Refer to the following information within the Peer Statistics tab:
Peer IP | Displays the IP addresses of the peer switches within the mobility domain. Each peer can |
| handle up to a maximum of 500 MUs. |
JOIN Events | Displays the number of JOIN messages sent and received. JOIN messages advertise the |
sent/rcvd | presence of MUs entering the mobility domain for the first time. When a MU (currently not |
| present in the MU database) associates with a switch, it immediately sends a JOIN message |
| to the host switch with the its MAC, VLAN and IP information (both current and home switch |
| IP info). The home switch forwards the JOIN to all its peers, except the one from which it |
| received the original message. JOIN messages are always originated by the current switch. |
| JOIN messages are also used during the home switch selection phase to inform a candidate |
| home switch about a MU. The current switch selects the home switch (based on its local |
| selection mechanism) and sends a JOIN message to the home switch that is forwarded it to |
| all its peers. |
LEAVE Events | Displays the number of LEAVE messages sent and received. LEAVE messages are sent when |
sent/rcvd | the switch decides a MU originally present in the MU database is no longer present in the |
| mobility domain. The criterion to determine the MU has actually left the network is |
| implementation specific. The current switch sends the LEAVE message with the MU's MAC |
| address information to the home switch, which eventually forwards the message to each |
| mobility peer. |
Displays the number Layer 2 ROAM messages sent and received. When a MU roams to a | |
sent/rcvd | new switch on a different layer 3 network (MU is mapped to a different VLAN ID), it sends a |
| |
| is associated with. The |
| peer. |
Displays the number Layer 3 ROAM messages sent and received. When a MU roams to a | |
sent/rcvd | new current switch on the same layer 3 subnet as the old current switch), it sends a L2- |
| ROAM message to the old home switch with the new home |
| information. This |

5.5.4Reviewing Layer 3 MU Status
The Layer 3 Mobility MU Status tab displays a set of MU stats for associated MUs within the mobility domain. Use the MU status information to familiarize yourself with these MUs and their
To view Layer 3 mobility MU statistics
1.Select Services > Layer 3 Mobility from the main menu tree.
The Layer 3 Mobility screen appears with the Configuration tab displayed.
