Will HSRP work on SUP(Supervisory engine) level?

or we can only use on switch level???

Are you referring to hybrid CatOS/IOS? HSRP is a layer 3 protocol, so it will only work on a layer 3 interface. In hybrid mode, this means on the MSFC level.

If I'm off base, please clarify the situation.

situation is that,we have to use HSRP on our two 6513 switch and in that only one SUP engin available per switch.so how we can use HSRP here ? we have to use HSRP on switch or on SUP?

So if you have a trunk between the switches and your vlans span both switches, you can absolutely turn on HSRP in the VLAN interface in the IOS portion. We do this all over our enterprise. Here's a config snippet:

Primary HSRP node:

interface Vlan10

description Server Vlan

ip address 1.1.1.2 255.255.255.0

standby 100 ip 1.1.1.1

standby 100 priority 110

standby 100 preempt

------------

Secondary HSRP node (2nd 6509):

interface Vlan10

description Server Vlan

ip address 1.1.1.3 255.255.255.0

standby 100 ip 1.1.1.1

standby 100 priority 105

standby 100 preempt

That will allow the default gateway (1.1.1.1) to fail between the two VLAN interfaces on separate 6509s.

Let me know if you need further clarification.
