Hi guys,
Is there a way to remove a vlan from an active uplink ?
I need to change some of the vlans on an active uplink, and I get an error saying that they are in use. In the lab I was able to reconfigure and remove a vlan from uplinks by removing the pNICs from every attached host in the profile. But in this case that would be disruptive.
Thanks,

use 'switchport trunk allowed vlan remove'
rsn1-1c-n1k(config)# port-profile vm-uplink
rsn1-1c-n1k(config-port-prof)# switchport trunk ?
allowed Set allowed VLAN characteristics when interface is in trunking mode
native Set trunking native characteristics when interface is in trunking mode
rsn1-1c-n1k(config-port-prof)# switchport trunk allowed vlan remove

Hey, thanks for the quick reply. Here's what my uplink looks like:
port-profile type ethernet uplink-storage
vmware port-group
switchport mode trunk
switchport trunk native vlan 5
switchport trunk allowed vlan 5,6-7
no shutdown
system vlan 6-7
state enabled
and then I have a port profile for the vlan
port-profile type vethernet os-storage
vmware port-group
switchport mode access
switchport access vlan 7
no shutdown
system vlan 7
max-ports 128
state enabled
what I want to do here is remove vlan 7 from the storage-uplink and add it to a different uplink, maintaining my os-storage port profile.
When I do:
conf t
port-profile type ethernet uplink-storage
switchport trunk allowed vlan remove 7
I get:
ERROR: This config blocked for system vlan profiles. Remove system vlans and retry.
If I try to remove the system vlan
port-profile type ethernet uplink-storage
no system vlan 7
This will remove all system vlans from this port profile. Do you really want to proceed(yes/no)? [yes] yes
ERROR: Cannot remove system vlans, port-profile currently in use by interface Eth3/3
Like I said in the first post, I've only been able to remove vlans from an uplink by removing all hosts pNICs from the uplinks, but I'm convinced there's a way for this to work.
