management by default. Looking at the VLAN table with the show vlan command, we can see there are three VLANs configured in addition to the default VLAN 1: 3750-IOS#sho vlan VLAN Name Status Ports default active Gi1/0/1, Gi1/0/2, Gi1/0/3 Gi1/0/4, Gi1/0/5, Gi1/0/6 Gi1/0/7, Gi1/0/8, Gi1/0/9 Configuring SVIs Gi1/0/10, Gi1/0/11, Gi1/0/13 Gi1/0/14, Gi1/0/15, Gi1/0/16 Text Removed --] Gi1/0/44, Gi1/0/45, Gi1/0/46 Gi1/0/49, Gi1/0/50, Gi1/0/51 Gi1/0/52 VLAN0002 active Gi1/0/12 VLAN0003 active VLAN0004 active VLAN Name Status Ports VLAN0100 active 1002 fddi-default act/unsup 1003 token-ring-default act/unsup 1004 fddinet-default act/unsup 1005 trnet-default act/unsup These VLANs are strictly Layer 2, in that the switch will not route between them. For the switch to access these VLANs at higher layers, we need to create an SVI for each one. To create SVIs on a Nexus 7000, you must first enable the feature with the feature interface-vlan global command. The only step required to create an SVI is to define it. Simply by entering the global configuration command interface vlan vlan#, you will create the SVI. The vlan# does not need to match an existing VLAN. For example, defining an SVI for VLAN 200, which does not exist on our switch, will still result in the SVI being created. We can even assign an IP address to the interface and enable it with the no shutdown command: 3750-I0S(config)#int vlan 200 3750-I0S(config-if)# 00:11:40: %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan200, changed state to 3750-I0S(config-if)#ip address 10.200.0.1 255.255.255.0 3750-I0S(config-if)#na shut The interface will initially be down/down because there is no VLAN at Layer 2 to support it. The hardware type is EtherSVI, indicating that this is a logical SVI: 3750-IOS#sho int vlan 200 Vlan200 is down, line protocol is down Hardware is EtherSVI, address is 001c.b0a9.6541 (bia 001c.b0a9.6541) Internet address is 10.200.0.1/24 MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation ARPA, loo
