What is dot1Q encapsulation command?
Router(config-subif)# encapsulation dot1q 1. Enables IEEE 802.1Q encapsulation of traffic on a specified subinterface in VLANs, and defaults the associated VLAN as a native VLAN. Step 3. Router(config-subif)# bridge-group bridge-group. Assigns each network interface to a bridge group.
What is dot1Q native VLAN?
The IEEE 802.1Q trunking protocol describes something called the native VLAN. All native VLAN traffic is untagged; it doesn’t have an 802.1Q tag on the Ethernet frame. When you look at it in Wireshark, it will look the same, just like any standard Ethernet frame.
In which memory location are the VLAN configurations of normal range VLANs stored on a Catalyst switch?
Normal range VLANs are stored in a file called vlan. dat and located in the flash memory.
What is the purpose of encapsulation dot1q?
As 802.1q encapsulation inserts an additional field into the Ethernet frame, Frame Check Sequence(FCS) is recalculated. All switches support 802.1q encapsulation. VLAN implementations have shown an increase in the performance, scalability and security of the entire network.
What is 802.1Q trunking?
VLAN Trunking (802.1Q) allows physical network interfaces in a computing environment to be shared, or multi-homed. Network devices on the network then only interact with packets that have the correct tags. This allows multiple different logical networks to run on the same cable and switch infrastructure.
Which type of VLAN would accommodate untagged traffic on a 802.1 Q trunk port?
A native VLAN is used to forward untagged frames that are received on a Cisco switch 802.1Q trunk port. Untagged frames that are received on a trunk port are not forwarded to any other VLAN except the native VLAN. Port Fa0/11 on a switch is assigned to VLAN 30.
Which command will allow a network administrator to check the IP address that is assigned to a particular MAC address group of answer choices?
Which command will allow a network administrator to check the IP address that is assigned to a particular MAC address? The show ip dhcp binding command will show the leases, including IP addresses, MAC addresses, lease expiration, type of lease, client ID, and user name.
What is the purpose of VTP?
The purpose of VTP is to provide a way to manage Cisco switches as a single group for VLAN configuration purposes. For example, if VTP is enabled on Cisco switches, the creation of a new VLAN on one switch makes that VLAN available to all switches within the same VTP management domain.
What are the 3 types of VLANs?
Types of VLAN
- Management VLAN.
- Data VLAN.
- Voice VLAN.
- Default VLAN.
- Native VLAN.
Is native VLAN necessary?
In order to configure native VLAN, switch port trunk native VLAN command is used. Native VLANs are recognized if they are not tagged to any trunks. It is not necessary to have native VLAN on the trunk.
Which is true VTP?
Solution(By Examveda Team) You must set the VTP domain name on all switches to be the same domain name or they will not share the VTP database.
Why are there only 4096 VLANs?
One reason could be for future use but 4096 port switch is hard to see in of VLANs allowed on a switch is 4096 which is huge compared to the maximum possibility of VLANs which will actually work at a time on a 24 port switch can be up to 24 only (if we have each port in a different VLAN).
When would you use a trunk port?
A trunk port allows you to send all those signals for each switch or router across a single trunk link. In contrast to an access port, a trunk port must use tagging in order to allow signals to get to the correct endpoint. Trunk ports typically offer higher bandwidth and lower latency than access ports.
