Hi,one of our sites has 2 switches acting as core with hsrp enabled.
Suddenly, last 2 weeks i have noticed that there are some strange messages on the 2nd switch, which is the standby one.
These messages dont appear on primary switch.I have attached the relevant shots.There werent any changes done.
Please advise the possible cause & what should be the rectification?
2)If the 2 switches are connected to each other via fiber patches over gigabit channels , does the hsrp communication take place over these uplinks?What would be the possible issues that would arise if any of these are inactive/down state between the 2 switches?
Yes, the VIP is an IP address that is shared by both vlan 94 interfaces on both switches. They must be the same for any particular HSRP group.
[EDIT} As for the IP address of the interfaces, I just noticed that you are using a /23 mask, so they are indeed both in the same vlan. My mistake. [EDIT]
[EDIT 2] OK, lets try this again. :-) I was right the first time. The IP addresses on the vlan interfaces ARE in different vlans. One is 10.34 and the other is 10.35. I have a horrible sinus infection and the meds are making me more stupid than usual. Sorry.
To summarize: The IP addresses of the interfaces must be in the same subnet and the VIP for each vlan interface must be the same. [EDIT 2]
