12.3 Verify VLT/vPC configuration on upstream switches
Configuring a single VLT domain with Dell EMC Networking upstream switches or a single vPC domain with
Cisco upstream switches is required. Creating two VLT/vPC domains may cause a network loop. See
Scenario 1 and Scenario 2
for the topology used in the deployment example.
The following example shows a mismatch of the VLT domain IDs on VLT peer switches. To resolve this issue,
ensure that a single VLT domain is used across the VLT peers.
Z9100-Leaf1# show vlt 1
Domain ID : 1
Unit ID : 1
Role : primary
Version : 1.0
Local System MAC address : 4c:76:25:e8:f2:c0
Z9100-Leaf2# show vlt 30
Domain ID : 30
Unit ID : 1
Role : primary
Version : 1.0
The following example shows a mismatch of the vPC domain IDs on vPC peer switches. To resolve this
issue, ensure that a single vPC domain is used across the vPC peers.
Nexus-3232C-Leaf1# show vpc
Legend:
(*) - local vPC is down, forwarding via vPC peer-link
vPC domain id : 1
Peer status : peer link is down
vPC keep-alive status : peer is alive, but domain IDs do not match
---- OUTPUT TRUNCATED -----
3232C-Leaf2# show vpc
Legend:
(*) - local vPC is down, forwarding via vPC peer-link
vPC domain id : 255
Peer status : peer link is down
vPC keep-alive status : peer is alive, but domain IDs do not match
---- OUTPUT TRUNCATED -----
12.4 Discovery of FEM and compute sleds
The following can be verified if server or FEM discovery doesn’t happen:
• If there is no link indicated on the FSE port, toggle the auto-negotiation settings for that port.
• Ensure that the compute sled is properly seated in the compute slot in the MX chassis.
• Make sure that the compute sled is turned on.
• Ensure that the drivers and firmware for BIOS, iDRAC, NICs and/or CNAs on the compute sleds are up to
date.
