Hello,
we have confgured a basic vPC Cluster with two Nexus 5672UP and Version 7.1(0)N1(1b).
Spanning Tree priority is on both switches the same.
Problem:
Several SVIs with HSRP v2 are configured but HSRP neighborship doesn't come up. On the log we saw the following:
2001 Sep 16 16:01:20 xxxxxx %ARP-3-DUP_VADDR_SRC_IP: arp [3819] Source a
ddress of packet received from 0000.yyy.xxxx on Vlan666(port-channel10) is dupl
icate of local virtual ip, 10.17.22.1
It seems to be both switches saw the HSRP VIP as a duplicate IP from each other. HSRP config is basic:
interface Vlanxxx
no shutdown
no ip redirects
ip address 10.0.x.x/22
hsrp version 2
hsrp 1
priority 120
ip 10.0.x.1
ip dhcp relay address y.y.y.y
Can anyone support or know a solution here?
Thanks
Udo

I have rebuild the configuration and also make on both switches a reload. Nothing works...:-(
Now I'm going to be make an update to the recommend version 7.1(4)N1(1).

I test this configuration on VIRL NXOSv and it's the same behavior..:-(
Version: 7.3(0)D1(1)

Weird. Let me see if I can lab it up.

Problem is solved. The base license was not available.

Yes, that has never happened to me before. Especially since the base license is actually included as standard. You can not order the switch without this license.;-)
