To deactivate HSRP, step one would be to remove HSRP from the standby interfaces. The active machine will keep acting as the default router. If you do not want any disruptions, this is how you should leave it.
To clear HSRP up completely, you must also remove hsrp from the active interface and change the ip adress of that interface to the hsrp-adress. This will mean loss of connectivity while the virtual mac that's used for hsrp will be removed also when you disable hsrp processing on the interface.
Do you also want to do all routing in one chassis?
With HSRP you typically divide the active gateways between the two chassis. If this is the case for your situation, you must move all HSRP-active nodes to one machine by altering the standby priorities.
Remember that this may also involve changes to the spanning tree configuration.
I think you must be running HSRP is single chassis only if I am not wrong which is also known as DRM(Dual Router Mode) where both the MSFC's can be active at a same time and now you want to move to SRM.
You can simple remove the standby groups from the msfc which is placed in standby sup first and then cane remove the standby groups from msfc which is in active sup and then imply the SRM commands.
The chassis is 6509 to 2 WS-F6K-MSFC2. I tried to remove HSRP but kept loosing connection to my second MSFC. when removing the HSRP configs on VLAN1. Which mean I'm still unable to set up SRM. Should completely remove HSRP before configuring SRM
If you remove config related to HSRP groups on standby MSFC the vlans which are active on that MSFC will start flowing their traffic from another MSFC which will be active for them now.
So it will loose a traffic for approx 10 seocnds and connection will resume again from active msfc but remember once you remove config from active msfc also to change the config to SRM then there will definetely be a downtime. So my recommendation is to arrage a downtime and then change the configs.
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
