If the ping fails, it means that the connectivity between both mgmt0 interfaces does not exist or that
they are not interconnected properly.
Make sure the mgmt0 interface is unshut and that you can ping the switch mgmt0 interface.
switch# sh int br | grep mgmt0
mgmt0
If the status shows that it is down, it means there is no physical connection to mgmt0 or that the
interface is in admin shutdown. You need to verify the physical connectivity and unshut the port:
switch1# config t
switch1(config)# int mgmt 0
switch1(config-if)# no shut
switch1(config-if)# show int br | grep mgmt0
mgmt0
If pinging the other switch continues to fail, then there is an interconnection issue between the two
Nexus 5000 switches.
Check the networking in between the switches:
• Check the vPC configuration and compare the mgmt0 IP addresses that are used:
switch1# show run int mgmt 0
!Command: show running-config interface mgmt0
!Time: Tue Mar
version 4.2(1)N2(1)
interface mgmt0
switch1# show run vpc
!Command: show running-config vpc
!Time: Tue Mar
version 4.2(1)N2(1)
feature vpc
vpc domain 500
switch2# show run int mgmt 0
!Command: show running-config interface mgmt0
