HSRP Continued

Continuing with my HSRP post decided to finish it off b4 i hit the sacks today.

Gateway1(config-if)# standby delay minimum [min-delay] reload [reload-delay]

Configures the delay period before the initialization of Hot Standby Router Protocol (HSRP) groups.

I dunn use this and would like to see the changes immediately.

If i do not use the preempt in the interface configuration then the HSRP does not shift to a router when i make its priority higher than the regular one. In that case if will only shift if there is a router failure.

Generally it is a good idea to have preempt so that you have better control over how the traffic flows in the network.

Enabling HSRP MIB Traps

MIB traps will help you poll the router through a snmp agent like snmpwalk , mrtg , rrdool and any other that you may write or get.

Enabling HSRP MIB trap support is done from the command-line interface (CLI), and the MIB is used for getting the reports. A trap notifies the network management station when a router leaves or enters the active or standby state. When an entry is configured from the CLI, the RowStatus for that group in the MIB immediately goes to the active state.

The Cisco IOS software supports a read-only version of the MIB, and set operations are not supported.

Step 1
Gateway1(config)# snmp-server enable traps hsrp

Enables the router to send SNMP traps and informs, and HSRP notifications.

Step 2
Gateway1(config)# snmp-server host host community-string hsrp

Specifies the recipient of an SNMP notification operation, and that HSRP notifications be sent to the host.

My configration has only been for only one router but you have to replicate to the other router as well.

Well thats all for now. Next post may have information on how to channel ports to save on High network usage .... It helped me a lot though.
