Review Question Ch. 11 Flashcards
Write the command that must be present for this layer 3 switch to provide inter-VLAN routing between the two VLANs
ip routing
In the following diagram, how must the port on each end of the line be configured to carry traffic between the four hosts?
Trunk. Trunk links carry traffic for multiple VLANs
What is the only type of second VLAN of which an access port can be a member?
Voice.
While in all other cases access ports can be a member of only one VLAN, most switches will allow you to add a second VLAN to an access port on a switch port for your voice traffic; it’s called the voice VLAN. The voice VLAN used to be called the auxiliary VLAN, which allowed it to be overlaid on top of the data VLAN, enabling both types of traffic through the same port.
Write the command that places an interface into VLAN 2
switchport access vlan 2
In the configuration and diagram shown, what command is missing to enable inter-VLAN routing between VLAN 2 and VLAN 3?
‘encapsulation dot1q 2’ under int f0/0.2
The encapsulation command specifying the VLAN for the subinterface must be present under both subinterfaces
What is happening in the picture?
This is a multilayer switch.
Enables IP routing and created one logical interface for each VLAN using the interface vlan ‘number’ command. Then it is doing inter-VLAN routing on the backbone of the switch
192.168.1.65
The host’s default gateway should be set to the IP address of the subinterface that is associated with the VLAN of which the host is a member, in this case VLAN 2
What is the purpose of frame tagging in virtual LAN (VLAN) configurations?
Frame identification over trunk links
What is a native VLAN?
A native VLAN is the untagged VLAN on an 802.1q trunked switchport. Basically, if a switch receives untagged frames on a trunkport, they are assumed to be part of the VLAN that is designated on the switchport as the native VLAN.
Write the command that prevents an interface from generating DTP frames.
switchport nonegotiate
