What is VLAN interface mode?

A VLAN interface is always up, but its line protocol state tracks the state of connected ports: if at least one port is operational, the line protocol for the VLAN interface is up, otherwise it is down.

How do I check VLAN status?

The show vlans command displays the VLANs currently running in the switch with the VID, VLAN name, and VLAN status. Dynamic VLANs appear only if the switch is running with GVRP enabled and one or more ports are dynamically connected to an advertised VLAN. In the default configuration, GVRP is disabled.

What is the purpose of Lldp?

How to connect VLAN 1 to VLAN 2?

The simplest way to enable routing between the two VLANs is to simply connect an additional port from each VLAN to a router. The router doesn't know it has two connections to the same switch — and it doesn't need to. The router operates as normal when routing packets between two networks.

What type of VLAN is the default VLAN?

The default VLAN for Cisco switches is VLAN 1. VLAN 1 has all the features of any VLAN except that you cannot rename it and you cannot delete it. Layer 2 control traffic, such as CDP and spanning tree protocol traffic, will always be associated with VLAN 1 – this cannot be changed.

How do I know if a VLAN is active?

Use the show vlan command to verify your VLAN configuration. This command displays all switch ports and their associated VLAN as well as VLAN status and some additional parameters related to Token Ring and FDDI trunks. You can use the show vlan id [vlan#] command to view information about a specific VLAN.
