AP VRRP

The VRRP screen displays VRRP (Virtual Router Redundancy Protocol) 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. Expand the System node from the navigation pane (on the left-hand side of the screen). The System node expands to display the RF Domains created within the managed network.
  3. Expand an RF Domain node, select a controller or service platform, and select one of its connected access points. The access point's statistics menu displays in the right-hand side of the screen, with the Health tab selected by default.
  4. Select VRRP.
    The Statistics > AP > L2TPv3 Tunnels screen is displayed.
    Click to expand in new window
  5. 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.

  6. 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 associated with the virtual router and accepts packets addressed to the IP associated with the virtual router.
    Interface Name

    Displays the interfaces selected on the access point to supply VRRP redundancy failover support.
    Version

    Display VRRP version 3 (RFC 5798) or 2 (RFC 3768) as selected to set the router redundancy. Version 3 supports sub-second (centisecond) VRRP failover and support services over virtual IP.
    State

    Displays the current state of each listed virtual router ID.
  7. Select Clear Router Status to clear the Router Operations Summary table to zero and begin new data collections.
  8. Select Clear Global Error Status to clear the Global Error Status table values to zero and begin new data collections.
  9. Select Refresh to update the screen's statistics counters to their latest values.
