802.1Q |
The IEEE standardized protocol for VLAN trunking.
(Wendell, 2013 Sect. Glossary) |
|
Trunk
|
In campus LANs, an Ethernet segment over which the frame exists.
(Wendell, 2013 Sect. Glossary) |
|
Trunking Administrative Mode
|
The configured trunking setting on a Cisco switch interfacee, as configured with the switchport mode command.
(Wendell, 2013 Sect. Glossary) |
|
Trunking Operational Mode |
The current Behavior of a Cisco switch interface for VLAN trunking.
(Wendell, 2013 Sect. Glossary) |
|
VTP
|
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) |
|
Layer 3 Switch |
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) |
|
Access Interface |
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) |
|
Trunk Interface |
A switch interface configured so that it operates using the VLAN in which a frame exists
(Wendell, 2013 Sect. Glossary) |
|
VTP transparent mode
|
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) |
|
VLAN
|
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) |
|
Configuration Command |
Global config command that both creates the VLAN and puts the CLI into VLAN configuration
(Wendell, 2013 p.261) |
|
Configuration Command
name |
VLAN subcommand that names the VLAN
(Wendell, 2013 p.261) |
|
Configuration Command |
VLAN mode subcommand that enables (no shutdown) or disables (shutdown) the VLAN
(Wendell, 2013 p.261) |
|
Configuration Command |
Global Config Command that defines the VTP mode
(Wendell, 2013 p.261) |
|
Configuration Command |
Interface subcommand that configures the trunking administrative mode on the interface.
(Wendell, 2013 p.261) |
|
Configuration Command |
Interface subcommand that defines the list of allowed VLANs
(Wendell, 2013 p.261) |
|
Configuration Command
switchport access vlan |
Interface subcommand that configures the interface into that one vlan
(Wendell, 2013 p.261) |
|
Configuration Command
switchport trunk encapsulation {dot1q|isl|negotiate} |
Interface subcommand that defines which type of trunking to use, assuming that trunking is configured or negotiated
(Wendell, 2013 p.261) |
|
Configuration Command |
Interface subcommand that defines the native VLAN for a trunk port
(Wendell, 2013 p.261) |
|
Configuration Command
Switchport nonegotiate |
Interface subcommand that disables the negotiation of VLAN trunking
(Wendell, 2013 p.261) |
|
