Chapter 2 Ethernet Commands shutdown (VLAN configuration) Send comments to [email protected] shutdown (VLAN configuration) To shut down the local traffic on a VLAN, use the shutdown command. To return a VLAN to its default operational state, use the no form of this command. shutdown no shutdown Syntax Description This command has no arguments or keywords. Command Default Not shut down. Command Modes VLAN configuration mode Command History Release 4.0(0)N1(1a) Modification This command was introduced. Usage Guidelines You cannot shut down, or disable, VLAN 1 or VLANs 1006 to 4094. After you shut down a VLAN, the traffic ceases to flow on that VLAN. Access ports on that VLAN are also brought down; trunk ports continue to carry traffic for the other VLANs allowed on that port. However, the interface associations for the specified VLAN remain, and when you reenable, or recreate, that specified VLAN, the switch automatically reinstates all the original ports to that VLAN. To find out if a VLAN has been shut down internally, check the Status field in the show vlan command output. If a VLAN is shut down internally, one of these values appears in the Status field: • act/lshut-VLAN status is active and shut down internally. • sus/lshut-VLAN status is suspended and shut down internally. Note If the VLAN is suspended and shut down, you use both the no shutdown and state active commands to return the VLAN to the active state. Examples This example shows how to restore local traffic on VLAN 2 after you have shut down, or disabled, the VLAN: switch(config)# vlan 2 switch(config-vlan)# no shutdown OL-16599-01 Cisco Nexus 5000 Series Command Reference 2-45
