Expert Answer

 

1)Answer:

Show vlan

Cisco show vlan is used to display VLAN information, use the show vlan command in privileged EXEC mode.

show vlan [brief | id vlan-id | name name [ifindex] | ifindex].

3)Answer:

VLAN 1 as the untagged default VLAN and VLANs 2, 3, and 4 as tagged VLANs.

4)Answer:

The following should be considered when implementing VLANs

1- VLAN 1 is the default VLAN.

2- The Native VLAN should be changed.

3- The maximum number of VLANs is switch dependent

5)Answer:

The following can be verified in the output of the show interfaces trunk command

  • 1- The administrative mode used to form the trunk.
  • 2- The interfaces are trunks.
  • 3- The encapsulation method used for the trunk.

Cat3550#show interfaces trunk
—–
Port Mode Encapsulation Status Native vlan
Fa0/17 trunk 802.1q other 1
Fa0/18 trunk 802.1q other 1
Fa0/19 trunk 802.1q other 1
