hi all,
i've got a weird behavior on one of mine ESX hosts.
when i execute a show command related to a specific module / interface the output takes some time and sometimes generates an error.
The ESX host is patched to the latest release and im running N1kv 1(2).
have a look at the commands:
a show mod indicates nothing suspicious:
N1kv# sh mod

when i take a look at the interfaces with show int x/x for the eth / po interfaces i get an error :
N1kv# sh int po 1

it takes some time till the output is displayed (app 10-15sek).
on the veth side i have the same delay but no error message is displayed.
thats my config of the uplink port-profile

switchport mode trunk
switchport trunk native vlan 210
switchport trunk allowed vlan all
channel-group auto mode on mac-pinning

state enabled
the ESX host is accessible and traffic also passes the VEM.
i had this issue some weeks ago but a simple reboot of the host did the job - since this is the second time I'll keep the host running.
maybe we can investigate together what might cause this behavior.
