Chapter 9 Vocab And Command References - Implementing Ethernet Virtual Lans

Front 1

802.1Q

Back 1

The IEEE standardized protocol for VLAN trunking.

(Wendell, 2013 Sect. Glossary)

Front 2

Trunk

Back 2

In campus LANs, an Ethernet segment over which the frame exists.

(Wendell, 2013 Sect. Glossary)

Front 3

Trunking Administrative Mode

Back 3

The configured trunking setting on a Cisco switch interfacee, as configured with the switchport mode command.

(Wendell, 2013 Sect. Glossary)

Front 4

Trunking Operational Mode

Back 4

The current Behavior of a Cisco switch interface for VLAN trunking.

(Wendell, 2013 Sect. Glossary)

Front 5

VTP

Back 5

VLAN Trunking Protocol

A Cisco proprietary messaging protocol used between Cisco switches to communicate configuration information about the existence of VLANs, including the VLAN ID and VLAN name.

(Wendell, 2013 Sect. Glossary)

Front 6

Layer 3 Switch

Back 6

Multilayer Switch

A LAN switch that can also perform Layer 3 routing functions, The name comes from the fact that this device makes forwarding decisions based on logic from multiple IOS layers (Layers 2 and 3)

(Wendell, 2013 Sect. Glossary)

Front 7

Access Interface

Back 7

A LAN network design term that reefers to a switch interface connected to end-user devices, configured so that it does not use VLAN trunking.

(Wendell, 2013 Sect. Glossary)

Front 8

Trunk Interface

Back 8

A switch interface configured so that it operates using the VLAN in which a frame exists

(Wendell, 2013 Sect. Glossary)

Front 9

VTP transparent mode

Back 9

One of three VTP operatational modes. Switches in transparent mode can configure VLANs, tell other switches about the changes, and learn about VLAN changes from other switches,

(Wendell, 2013 Sect. Glossary)

Front 10

VLAN

Back 10

Virtual LAN

A group of devices, connected to one or more switches, with the devices grouped into a single broadcast domain through switch configuration. VLANs allow switch administrators to separate the devices connected to the switches into separate VLANs without requiring separate physical switches, gaining design advantages of separating the traffic without expense of buying additional hardware.

(Wendell, 2013 Sect. Glossary)

Front 11

Configuration Command

vlan

Back 11

Global config command that both creates the VLAN and puts the CLI into VLAN configuration

Front 14

Configuration Command

vtp mode {server|client|transparent|off}

Front 16

Configuration Command

switchport trunk allowed vlan {add|all|except|remove}

Back 16

Interface subcommand that defines the list of allowed VLANs

(Wendell, 2013 p.261)

Front 18

Configuration Command

switchport trunk encapsulation {dot1q|isl|negotiate}

Back 18

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