I have Cisco Layer 3 switch with IP routing enabled on it. I have different VLANs configured on it and its working perfectly. Now i have added another VLAN (SVI) and assigned that VLAN to one of the port , but VLAN interface is still showing "VLAN350 is down, line protocol is down". I made sure i entered "no shutdown" command on SVI and physical interface. Following is my config. Please tell me what i am doing wrong.

ip dhcp pool VLAN-350-POOL
 network 192.168.10.0 255.255.255.0
 default router 192.168.10.1
 dns-server 8.8.8.8 8.8.4.4
 lease 2

spanning-tree mode rapid-pvst
spanning-tree loopguard default
spanning-tree portfast bpduguard default
spanning-tree extend system-id
spanning-tree vlan 1,100,200,300 priority 0

interface GigabitEthernet1/9
 switchport access vlan 350
 switchport mode access
 keepalive 1
 speed 1000
 duplex full
 spanning-tree portfast

interface vlan350
ip address 192.168.10.1 255.255.255.0

I have attached a laptop to Gigabit Port 1/9 and its not getting any IP address from the pool (Since VLAN350 is still not coming up).

Any help is appreciated. Thanks.
