The default allocation range is between VLAN 1006 and VLAN 4094.
## default d1#show vlan internal allocation policy Internal VLAN Allocation Policy: ascending Internal VLAN Allocation Range: 1006-4094 ## Specify range d1#show running-config section internal vlan internal order ascending range 3006 3999 d1#show vlan internal allocation policy Internal VLAN Allocation Policy: ascending Internal VLAN Allocation Range: 3006-3999 d1#show vlan internal usage 3006 Ethernet49/1 3007 Ethernet50/1 # Specify dynamic range as well d1(config)#vlan dynamic range 3900-3999 d1(config)#show vlan dynamic Dynamic VLAN source VLANS dot1x NONE dynvtep NONE evpn 3997-3999
The default settings might cause vlan collision if a internal vlan is in use already
d1(config)#show vlan internal usage 3006 Ethernet49/1 3007 Ethernet50/1 d1(config)#vlan 3006 % VLAN 3006 is in use as an internal VLAN. Cannot create it.
Dynamic vlans will just move dynamically as is seems
d1(config)#show vlan dynamic Dynamic VLAN source VLANS dot1x NONE dynvtep NONE evpn 3997-3999 d1(config)#vlan 3997 d1(config-vlan-3997)#name test d1(config-vlan-3997)#end d1#show vlan dynamic Dynamic VLAN source VLANS dot1x NONE dynvtep NONE evpn 3996,3998-3999
Do not set a dynamic vlan range outside of internal range. Things does not really work as intended
