Nexus 93180 xconnect down

[ez9]

Hello,

I am trying to enable a xconnect between two Cisco Nexus 93180. One interface is UP and the other is in down state (is down (xconnect remote down)

My configuration is the following:

Leaf A:

vlan 1376
name XCON_TEST
vn-segment 1001376
xconnect

int e1/15

  switchport
switchport mode dot1q-tunnel
switchport access vlan 1376
spanning-tree port type edge
spanning-tree bpdufilter enable

int nve 1

  member vni 1001376
   ingress-replication protocol bgp

Leaf B:

vlan 1376
name XCON_TEST
vn-segment 1001376
xconnect

int e1/30

  switchport
switchport mode dot1q-tunnel
switchport access vlan 1376
spanning-tree port type edge
spanning-tree bpdufilter enable

int nve 1

  member vni 1001376
   ingress-replication protocol bgp

Leaf A output:

show ngoam xconnect session all

States: LD = Local interface down, RD = Remote interface Down
HB = Heartbeat lost, DB = Database/Routes not present
* - Showing Vpc-peer interface info
Vlan Peer-ip/vni XC-State Local-if/State Rmt-if/State
===============================================================================
1376192.168.96.106 / 1001376 HB/ Eth1/15 / ERR Unknown / DOWN

Leaf B output:

show ngoam xconnect session all

States: LD = Local interface down, RD = Remote interface Down
HB = Heartbeat lost, DB = Database/Routes not present
* - Showing Vpc-peer interface info
Vlan Peer-ip/vni XC-State Local-if/State Rmt-if/State
===============================================================================
1376 192.168.105.105 / 1001376 Active Eth1/30 / UP Eth1/15 / ERR

Any insight?

      Also always check the logs on the nexus when using or starting to use the feature (just after configuring (e.g.))

Thanks for the answer. I checked this thread. The nexus 93180 not need any tcam carving. Doing some more research using the ethanalyzer I noticed that the one side is not receiving CFM/ngoam packets (although I can capture these packets using tcpdump from the nexus bash shell). This side by the way is a VPC pair. What would be the case for this?

Hi,

Unfortunately no solution yet. One side has the status HB = Heartbeat lost. I didn't figured out yet why this is happening. Any idea will be appreciated.
