Group Mobility Statistics
Rx Errors—Generic protocol packet receive errors, such as packet too short or format incorrect.
Tx Errors—Generic protocol packet transmit errors, such as packet transmission fail.
Responses Retransmitted—Mobility protocol that uses UDP and resends requests several times if it does not receive a response. Because of network or processing delays, the responder may receive one or more retry requests after it initially responds to a request. This text box shows a count of the response resends.
Handoff Requests Received—Total number of handoff requests received, ignored, or responded to.
Handoff End Requests Received—Total number of handoff end requests received. These requests are sent by the anchor or foreign controller to notify the other about the close of a client session.
State Transitions Disallowed—Policy enforcement module (PEM) that has denied a client state transition, usually resulting in the handoff being aborted.
Resource Unavailable—Necessary resource, such as a buffer, was unavailable, resulting in the handoff being aborted.
Mobility Initiator Statistics
Handoff Requests Sent—Number of clients that have associated to the controller and have been announced to the mobility group.
Handoff Replies Received—Number of handoff replies that have been received in response to the requests sent.
Handoff as Local Received—Number of handoffs in which the entire client session has been transferred.
Handoff as Foreign Received—Number of handoffs in which the client session was anchored elsewhere.
Handoff Denys Received—Number of handoffs that were denied.
Anchor Request Sent—Number of anchor requests that were sent for a three-party (foreign-to-foreign) handoff. The handoff was received from another foreign controller, and the new controller is requesting the anchor to move the client.
Anchor Deny Received—Number of anchor requests that were denied by the current anchor.
Anchor Grant Received—Number of anchor requests that were approved by the current anchor.
Anchor Transfer Received—Number of anchor requests that closed the session on the current anchor and transferred the anchor back to the requestor.
Mobility Responder Statistics
Handoff Requests Ignored—Number of handoff requests or client announcements that were ignored because the controller had no knowledge of that client.
Ping Pong Handoff Requests Dropped—Number of handoff requests that were denied because the handoff period was too short (3 seconds).
Handoff Requests Dropped—Number of handoff requests that were dropped due to either an incomplete knowledge of the client or a problem with the packet.
Handoff Requests Denied—Number of handoff requests that were denied.
Client Handoff as Local—Number of handoff responses sent while the client is in the local role.
Client Handoff as Foreign—Number of handoff responses sent while the client is in the foreign role.
Anchor Requests Received—Number of anchor requests received.
Anchor Requests Denied—Number of anchor requests denied.
Anchor Requests Granted—Number of anchor requests granted.
Anchor Transferred—Number of anchors transferred because the client has moved from a foreign controller to a controller on the same subnet as the current anchor.
