What VLAN 1003?
In some design case, VLAN is used to group user and set the policy for each group. Users in the same VLAN, they can communicate with each other without routing even if they are not located physically on the same LAN segment. The traffic from one VLAN to another VLAN must be routed.
What is valid VLAN number range?
VLAN Ranges
| VLANs | Range | Usage |
|---|---|---|
| 1 | Normal | Cisco default. You can use this VLAN but you cannot delete it. |
| 2-1001 | Normal | For Ethernet VLANs; you can create, use, and delete these VLANs. |
| 1002-1005 | Normal | Cisco defaults for FDDI and Token Ring. You cannot delete VLANs 1002-1005. |
| 1006-4094 | Extended | For Ethernet VLANs only. |
What is the purpose of default VLAN?
Conclusion. Finally, we can conclude that the basic purpose of native VLAN is to serve it as a common identifier on opposing ends of a trunk link. To carry untagged traffic which is generated by a computer device attached to a switch port, which is configured with the native VLAN.
What is a VLAN number?
A VLAN represents a broadcast domain. VLANs are identified by a VLAN ID (a number between 0 – 4095), with the default VLAN on any network being VLAN 1. Each port on a switch or router can be assigned to be a member of a VLAN (i.e., to allow receiving and sending traffic on that VLAN).
What is the VLAN 1002-1005 used for?
Prototype table VLAN ID Function VLAN 1002 Default FDDI VLAN VLAN 1004 Default FDDI NET VLAN VLAN 1005 (trbrf-default) with bridge nu Default Token Ring TrBRF VLAN VLAN 1003 (trcrf-default) Default Token Ring TrCRF VLAN
Why are VLANs not used in FDDI ring networks?
These VLANs were originally intended for bridging with FDDI an Token Ring networks but as these data link layer technologies are not in use anymore, these VLANs are unused. However, because of backward compatibility reasons in IOS and VTP, these VLAN numbers remain reserved and can not be used. 08-15-2012 01:28 AM 08-15-2012 01:28 AM
Is the Cisco 4948 compatible with VLAN 1001?
Their previous engineer had set them up on VLANs 1001, 1002, 1003, and 1004. I tried swapping them over to using a Cisco 4948 (which is a great switch) in their core, but as it turns out only VLAN 1001 would work.
Can A FDDI Lan be connected to a Ethernet LAN?
Therefore it was a common requirement to connect FDDI or Token Ring LANs to Ethernet LANs using bridging.
