Accesslinks
|
Alink that is used with switches and is part of only one virtual LAN(VLAN). Trunk links carry information from multiple VLANs.
|
|
|
Accessport
|
Configurationon a layer 2 switch port that sends and receives information aboutone VLAN only
|
|
|
Broadcastdomain
|
Agroup of devices receiving broadcast frames initiating from anydevice within the group. Because routers do not forward broadcastframes, broadcast domains are not forwarded from one broadcast toanother.
|
|
|
Flatnetworks
|
Networkthat is one large collision domain and one large broadcast domain.

IEEE802.1q
|
IEEE802.1Q is the networking standard that supports virtual LANs (VLANs)on an Ethernet network. The standard defines a system of VLAN taggingfor Ethernet frames and the accompanying procedures to be used bybridges and switches in handling such frames.
|
|
|
ISL
|
Inter-SwitchLink routing: A Cisco proprietary method of frame tagging in aswitched internetwork. Frame tagging is a way to identify the VLANmembership of a frame as it traverses a switched internetwork

Showinterface trunk
|
Todisplay information about all the trunk interfaces
|
|
|
Showvlan
|
Todisplay the status and information for VLANs
|
|
|
Trunklinks
|
Linkused between switches and from some servers to the switches. Trunklinks carry traffic for many VLANs. Access links are used to connecthost devices to a switch and carry only VLAN information that thedevice is a member of.
|
|
|
Trunkport
|
Atrunk port is a port that is assigned to carry traffic for all theVLANs that are accessible by a specific switch, a process known astrunking.
|
|
|
VLAN
|
VirtualLAN: A group of devices on one or more logically segmented LANs(configured by use of management software), enabling devices tocommunicate as if attached to the same physical medium when they areactually located on numerous different LAN segments. VLANs are basedon logical instead of physical connections and thus are tremendouslyflexible.

Whatis Router on a Stick? How do you set it up?
|
Itallows all VLANs to communicate through one interface. Use the subinterfaces of a connection to rout through one trunk port. -http://blog.alwaysthenetwork.com/tutorials/router-on-a-stick-tutorial/
