VRRP

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.

CTRL Connection ID

Displays the router ID(s) sent in tunnel establishment messages with a potential peer device.

Up Time

Lists the amount of time the L2TP connection has remained established amongst peers
sharing the L2TPv3 tunnel connection. Up Time is displayed in a Days: Hours: Minutes:
Seconds: format. If D:0 H:0 M:0 S:0 is displayed, the tunnel connection is not currently
established.

Encapsulation Protocol

Displays either IP or UDP as the peer encapsulation protocol. The default setting is IP. UDP
uses a simple transmission model without implicit handshakes. Tunneling is also called
encapsulation. Tunneling works by encapsulating a network protocol within packets carried by
the second network.

Critical Resource

Lists critical resources for this tunnel. Critical resources are device IP addresses on the
network (gateways, routers etc.). These IP addresses are critical to the health of the network.
These device addresses are pinged regularly by access points. If there’s a connectivity issue,
an event is generated stating a critical resource is unavailable.

VRRP Group

Displays the VRRP group name if configured. VRRP configurations support router redundancy
in a wireless network requiring high availability

Establishment Criteria

Displays the tunnel establishment criteria for this tunnel. Tunnel establishment involves
exchanging 3 message types (SCCRQ, SCCRP and SCCN) with the peer. Tunnel IDs and
capabilities are exchanged during the tunnel establishment with the host.

Refresh

Select the Refresh button to update the screen’s statistics counters to their latest value.
