Q

One of three VTP operational modes. Switches in this mode can configure VLANs, but they do not tell other switches about the changes, and they do not learn about VLAN changes from other switches

Q

One of three VTP operational modes. Switches in this mode learn about VLAN numbers and names from other switches, but this mode will not allow the switch to be directly configured with VLAN information

Q

A VLAN defined for used by IP phones, with the switch notifying the phone about the VLAN ID so that the phone can use 802.1Q frames to support traffic for the phone and the attached PC

16
Q

Command reference:

VLAN subcommand that names the vlan

A

name <i>vlan-name</i>

17
Q

Command reference:

VLAN mode command that enables (no shutdown) or disables (shutdown) the vlan

A

[no] shutdown

18
Q

Command reference:

Global command that has the same effect as the [no] shutdown VLAN mode subcommand

A

[no] shutdown vlan <i>vlan-id</i>

19
Q

Command reference:

Global command that defines the vtp mode

A

vtp mode [server | client | transparent | off]

20
Q

Command reference:

Interface subcommand that configures the trunking administrative mode on that interface

A

switchport mode {access | dynamic {auto | desirable} | trunk}

21
Q

Command reference:

Interface subcommand that statically configures the interface into that one VLAN

A

switchport access vlan <i>vlan-id</i>

22
Q

Command reference:

Interface subcommand that defines which type of trunking to use (encapsulation), assuming that trunking is configured or negotiated

A

switchport trunk encapsulation [dot1q | isl | negotiate]

23
Q

Command reference:

Interface subcommand that devices the native vlan for a trunk port

A

switchport trunk native vlan <i>vlan-id</i>

24
Q

Command reference:

Interface subcommand that disables the negotiation of VLNA trunking

A

switchport nonegotiate

25
Q

Command reference:

Interface subcommand that defines the voice vlan on a port, meaning that the switch uses 802.1Q tagging for frames in this VLAN

A

switchport voice vlan <i>vlan-id</i>

26
Q

Command reference:

Interface subcommand that defines the list of allowed VLANS

A

switchport trunk allowed vlan {add | all | except | remove} <i>clan-list</i>

27
Q

Command reference:

Lists information about any interface regarding administrative settings and operational state

A

show interfaces <i>interface-id</i> switchport

28
Q

Command reference:

Lists information about all operational trunks (but no other interfaces), including the list of VLANs that can be forwarded over the trunk

A

show interfaces <i>interface-id</i>trunk

29
Q

Lists information about the VLAN

A

show vlan {brief | id <i>vlan-id</i> | name <i>vlan-name</i> | summary}

30
Q

Displays VLAN information

A

show vlan <i>vlan-id</i>

31
Q

Lists VTP configuration and status information

A

show vtp status
