HSRP groups / Limit of 32 reached

[Fabien695]

Hi there,

Sorry in advance, I speak English with difficulty...

I have a problem with my network core: The limit of 32 groups is reached.

But I have only 32 standby IP address in the group 0...

The message "% More than 32 standby groups not supported in this platform" appeared...

At the moment, I'll create the others groups on others network core, but this solution is temporary.

My network cores: WS-C3750G-12S-S
iOS : 12.2(35)SE5 IPBase

So, I have two questions for you please :

• Actually in IPBase version, if I will upgrade my switchs with IPService version, is it solved the problem ? is the iOS "IPService" support more than 32 groups ?
• Is there an other solution to ensure failover that works like HSRP ? (VRRP ? how many groups are supported ?)

Any other issue or idea is welcome...

Thank you for all

Hi,

The maximum amount of 32 instances is the same for HSRP, VRRP and GLBP this is a hardware limitation not a matter of a IOS feature set. That said even if you upgrade to ipservices the amount of groups will not be higher.
