Cisco Hot Standby Routing Protocol Ext If Tracked Entry

1.3.6.1.4.1.9.9.107.1.1.1.1

Each row of this table allows the tracking of one interface of the HSRP group which is identified by the (ifIndex, cHsrpGrpNumber) values in this table's INDEX clause. Weight(priority) is given to each and every interface tracked. When a tracked interface is unavailable, the HSRP priority of the router is decreased. i.e cHsrpGrpPriority value assigned to an HSRP group will reduce by the value assigned to cHsrpExtIfTrackedPriority. This reduces the likelihood of a router with a failed key interface becoming the active router. Setting cHsrpExtIfTrackedRowStatus to active starts the tracking of cHsrpExtIfTracked by the HSRP group. The value of cHsrpExtIfTrackedRowStatus may be set to destroy at any time. Entries may not be created via SNMP without explicitly setting cHsrpExtIfTrackedRowStatus to either 'createAndGo' or 'createAndWait'. Entries can be created and modified via the management protocol or by the device's local management interface. If the row is not active, and a local management interface command modifies that row, the row may transition to active state. A row entry in the cHsrpExtIfTrackedTable can not be created unless the corresponding row in the cHsrpGrpTable has been created. If that corresponding row in cHsrpGrpTable is deleted, the interfaces it tracks also get deleted. A row which is not in active state will timeout after a configurable period (five minutes by default). This timeout period can be changed by setting cHsrpConfigTimeout.
