Hello network specialists!
I am having troubles with my n5k setup.
I have two N5K's, in VPC config.
HSRP Hello packets are not being forwarded on the VPC-peer link. So both devices are in HSRP active state.
I see (debug) that packets are being sent out the L3 vlan interfaces of both devices.
They are however not received by the neighboring device.
VLANs are active and in FWD state on peer-link.
NOTE: I have no L3 card! (Is this a problem?)

3 0 O2 Non L3 Daughter Card N55-DL2 ok
Any ideas why this wouldn't work? VRRP same problem.
