Hi Visha.

Hi Vishal,

It is like the all vlans are allowed through the specific trunk port and are in vlan management domain.

Cat3550#show interfaces trunk 

Port      Mode         Encapsulation  Status        Native vlan
Gi0/1     desirable    802.1q         trunking      1
Gi0/2     desirable    802.1q         trunking      1

Port      Vlans allowed on trunk
Gi0/1     1-4094
Gi0/2     1-4094

Port      Vlans allowed and active in management domain
Gi0/1     1-3,10
Gi0/2     1-3,10

Port      Vlans in spanning tree forwarding state and not pruned

Gi0/1     1-3,10
Gi0/2     1-3,10

 

Please click on the correct answer if this answered your question.
Regards,
Naidu.

Management domain means VTP domain. A VTP domain (also called a VLAN management domain).

In below example, vlans (1,13,23,37,51,146):  is allow "AND ACTIVE" in Management (VTP) domain

SW3#show trunk inter

Port Mode Encapsulation Status Native vlan
Gi0/1 auto n-802.1q trunking 1
Gi0/2 auto n-802.1q trunking 1

Port Vlans allowed on trunk
Gi0/1 1-4094
Gi0/2 1-4094

Port Vlans allowed and active in management domain
Gi0/1 1,13,23,37,51,146
Gi0/2 1,13,23,37,51,146

Port Vlans in spanning tree forwarding state and not pruned
Gi0/1 1,13,23,37,51,146
Gi0/2 none

Hello

On a side note:
If a vlan is allowed on the trunk (then its not being manually prunned) and its active in mgt domain but it isn't seen in vlan spanning-tree forwarding, this means vtp is enabled and has dynamically pruned it from the trunk

Example:
Port Vlans allowed on trunk
Gi0/1 13

Port Vlans allowed and active in management domain
Gi0/1 13

Port Vlans in spanning tree forwarding state and not pruned
Gi0/1
