Problem:

 

The switch has two VLANs as shown in the output below.

Aruba-2930F# show vlan

 Status and Counters - VLAN Information

  Maximum VLANs to support : 256
  Primary VLAN : DEFAULT_VLAN
  Management VLAN :

  VLAN ID Name                             | Status     Voice Jumbo
  ------- -------------------------------- + ---------- ----- -----
  1       DEFAULT_VLAN                     | Port-based No    No
  4000    VLAN4000                         | Port-based       No

 

When trying to edit or delete VLAN 4000, an error is displayed.

Aruba-2930F# configure terminal
Aruba-2930F(config)# no vlan 4000
4000: Dynamic VLANs cannot be deleted.

 



Diagnostics:

 

Identified that this VLAN is being learned through a configured device-profile on this switch.

Aruba-2930F# show vlan 4000

Below is the device profile configuration on the switch and we identified that VLAN 4000 is mapped to device-profile "IAP".

Aruba-2930F# show device-profile config

Solution

 

This VLAN cannot be deleted and needs to be removed from the device-profile configuration if not required.

 

To remove the VLAN from the device profile - 

Change the untagged-vlan in the device-profile to default VLAN (1) .

Aruba-2930F# configure terminal
Aruba-2930F(config)# device-profile name IAP untagged-vlan 1

 

After the change we see that the VLAN has disappeared from the switch.

Aruba-2930F# show vlan
