Use the encapsulation dot1q command in interface range mode to apply a VLAN ID to each subinterface within the range specified by the interface range command. The VLAN ID specified by the vlan-id argument is applied to the first subinterface in the range.
User-configured VLANs have unique IDs from 1 to 4094. To create a VLAN, enter the vlan command with an unused ID. To verify whether a particular ID is in use, enter the show vlan id ID command. To modify a VLAN, enter the vlan command for an existing VLAN.
Tagging Rules (Cont) On a given LAN segment VLAN, all frames implicitly or. Different VLANs on the different options. Access Link: Contain All frames on access. Hybrid Link: Contains and VLAN-unaware. All frames for some. All frames for other. for should explicitly. VLAN.
Note. You must enable the extended system ID to use 4096 VLANs (see the “Understanding the Bridge ID” section on page 28-2). dard. These VLANs are organized into several ranges; you use each range slightly differ. ntly. Some of these VLANs are propagated to other switches in the network when you use the VLAN Trunking Protocol .
Learning Objectives. Upon completion of this lab, you will be able to: Cable a network according to the topology diagram. Erase the startup configuration and reload a switch to the default state. Perform basic configuration tasks on a switch. Create VLANs. Assign switch ports to a VLAN. Add, move, and change ports. Verify VLAN configuration.
VLAN ID: identifies the number of the VLAN to which a frame belongs. The length of the VLAN ID is 12 bits. The value ranges from 0 to 4095. Because 0 and 4095 are reserved values of the protocol, the VLAN ID ranges from 1 to 4094. Network devices use VLAN IDs to identify the VLAN to which a frame belongs and
In general, VLANs make it easier to design a network to support the goals of an organization. VLAN trunks are used to span VLANs across multiple devices. Trunks allow the traffic from multiple VLANS to travel over a single link, while keeping the VLAN identification and segmentation intact.
