Nexus 9K Issue

[alexander.fuka1]

Hello All, I am receiving this error while trying to build a VPC on N9K. There are several other VPC already configured and working properly. Please see below:

2020 Apr 23 10:39:21 NX_FAN_9k-A %ETH_PORT_CHANNEL-5-PORT_SUSPENDED: (port omitted): (port ommited) is suspended

2020 Apr 23 10:39:29 NX_FAN_9k-A %ARP-3-DUP_VADDR_SRC_IP:  arp [27889]  Source address of packet received from (mac ommited) on Vlan1(port-channel31) is duplicate of local virtual ip, (ip omitted)

Hi @alexander.fuka1 

You can check the reason for the interface to be in suspended state using:

show interface poX

Who is the mac address of 'duplicate local VIP'?

Regards,

Sergiu

Hey @Sergiu.Daniluk 

When I did a show interface i saw it was suspended. I was told the other device was running LACP but apparently it was not... I changed the channel-group mode to ON and it is working properly. The logging message I posted did not seem to be the issue. Thank you for your help!
