Access Point Statistics
The VRRP statistics screen displays Virtual Router Redundancy Protocol (VRRP) configuration statistics supporting router
redundancy in a wireless network requiring high availability.
To review a selected access point’s VRRP statistics:
1. Select the Statistics menu from the Web UI.
2. Select System from the navigation pane (on the left-hand side of the screen). Expand a RF Domain and select one of its
connected access points.
3. Select VRRP.

4. Refer to the Global Error Status field to review the various sources of packet errors logged during the implementation of
the virtual route.
Errors include the mismatch of authentication credentials, invalid packet checksums, invalid packet types, invalid virtual
route IDs, TTL errors, packet length errors and invalid (non matching) VRRP versions.
5. Refer to the Router Operations Summary for the following status:
VRID Lists a numerical index (1 - 254) used to differentiate VRRP configurations. The index is
assigned when a VRRP configuration is initially defined. This ID identifies the virtual router a
packet is reporting status for.
Virtual IP Address Lists the virtual interface IP address used as the redundant gateway address for the virtual
route.
Master IP Address Displays the IP address of the elected VRRP master. A VRRP master (once elected) responds
to ARP requests, forwards packets with a destination link layer MAC address equal to the
virtual router MAC address, rejects packets addressed to the IP address associated with the
virtual router and accepts packets addressed to the IP address associated with the virtual
router.
