Symptom
After modifying 'switchport trunk native vlan' on N1k port-profile and upstream switch(es), CDP reports a mismatch.
%CDP-4-NATIVE_VLAN_MISMATCH: Native VLAN mismatch discovered on Ethernet1/4(2), with Ethernet101/1/1(1)
Conditions
This is a cosmetic issue on N1k. 'sh cdp neighbor int eth x/y detail' on upstream device will validate native vlan is advertised correctly.
Workaround
shut / no shut interface or port-channel
