You can create a VLAN by assigning a number to it you can delete VLANs as well as moving them from the active operational state to the suspended operational state.
The default VLAN (VLAN1) uses only default values, and you cannot create, delete, or suspend activity in the default VLAN. All configured ports belong to the default VLAN when you first bring up the switch. VLANs are numbered from 1 to 4094 (extended range). For more information on remote SPAN, see Chapter 29, Configuring SPAN and RSPAN in the CGS 2520 Software Configuration Guide. To display the VLAN configuration, enter the show vlan command. Certain types of switches can negotiate trunk links. Cisco switches have two Ethernet trunking mechanisms: ISL and IEEE 802.1Q. Trunk links provide VLAN identification for frames traveling between switches.
When you configure VLANs in global and config-vlan configuration modes, the VLAN configuration is saved in the vlan.dat files, not the running-config or startup-config files. VLANs are local to each switchs database, and VLAN information is not passed between switches.

VLANs have the same attributes as physical LANs, but you can group end stations even if they are not physically connected to the same switch. Configure the VLAN as the Remote Switched Port Analyzer (RSPAN) VLAN for a remote SPAN session. you can configure VLANs in global and VLAN configuration modes. UPDATED: 2020 Cisco Catalyst switches equipped with the Enhanced Multilayer Image (EMI) can work as Layer 3 devices with full routing capabilities.For example, some switch models that support layer 3 routing are the 3550, 3750, 3560 etc. Technology: Enterprise Switching Area: VLAN Vendor: Cisco Software: 12.X, 15.X Platform: Catalyst SwitchesĪ VLAN is a group of end stations in a switched network that is logically segmented by function, team or application, regardless to the physical locations of the users.
