[c-nsp] HSRP added to SVI, IP accounting no longer works.

[cisco group]

Hi,

After adding HSRP to our SVI we are no longer receiving data in IP
accounting.  I have attached before and after configs.  Is anyone able
to indicate what would be causing this?  Is it CEF related?  Can we
run IP accounting or will we need to look at migrating towards
NetFlow?

Disclaimer - for privacy reasons I have hidden our real IP addresses,
and removed the HSRP authentication commands
