VLAN-LAND
A logical overlay network that groups together a subset of devices that share a physical LAN, Isolating the traffic for each group.
This VLAN is default and to be avoided on threat of pain and torture by your network admin.
What is VLAN 1
These allow all VLAN traffic to propagate between switches and enables devices connected to different switches but in the same VLAN to communicate without going through a router.
What are trunks?
This cisco command is optional, but strongly recommended, as a security best practice and changes the interface to strictly access mode.
what is switchport mode access
One benefit of VLANS reduces the number for devices in this.
This VLAN is used to separate user-generated traffic.
What is a data VLAN
Cisco supports this standard for coordinating trunks.
What is IEEE 802.1Q?
This cisco command assigns a VLAN to a specific interface.
What is switchport access vlan (10)?
This benefit of VLANS results from the fact the only users in the same VLAN can communicate together.
What is improved security?
This type of trunk port inserts a 4-byte tag in the ethernet frame header to identify the VLAN to which the frame belongs.
What is a 802.1Q trunk port?
This is the true and false answer to: By default no VLANS are supported on a trunk port they have to be specified manually.
What is false?
This show command displays VLAN name, status, and its ports one VLAN per line
What is show vlan brief?
Being able to name the VLANS anything you want contributes to this VLAN benefit.
What is improved IT efficiency?
or
What is Simpler Project and application management?
802.1Q trunk port places untagged traffic on this type of VLAN.
What is native?
This is the true or false answer to this: By default all ethernet frame headers already contain the VLAN tags.
What is false
The proprietary protocol that lets switches automatically negotiate trunking with neighboring devices.
What is Dynamic Trunking Protocol (DTP)?
Smaller broadcast domains reduce unnecessary traffic on the network which leads to this VLAN benefit.
What is better performance?
What is Managment?
When a switch trunk port receives untagged frames they are forwarded to this type of VLAN.
What is native?
Static trunking is preferrable to dynamic.
What is true?
DAILY DOUBLE
These are all the cisco commands to assign all ports to F0/1, F0/2, F0/3, F0/4,F0/5, F0/7, G0/1 and G0/2 to vlan 10.
What is
int range f0/1-5, f0/7, G0/1-2
switchport mode access
switchport access vlan 10
end?
This type of VLAN and VoIP are best friends and essential together.
What is voice
This is Cisco's version of QoS on Layer two devices and is essential in VOICE VLAN traffic.
DAILY DOUBLE
These are the commands for configuring f0/1 trunk to vlans 10, 20 and 30 and vlan 99 as native.
What is
int f0/1
switchport mode trunk
switchport trunk native vlan 99
switchport trunk allowed vlan 10,20,30,99
end?
