Not able to add vlans (svi) on a 6500

Question

Hello all,
I am having an issue while trying to create a VLAN/SVI interface on my 6500 Metro Ethernet Aggregator.
I am receiving an error message that I cannot create an SVI without having the vlan added on the L2 vlan database, but the issue is that the vlan is already created there:
1. I created the vlan on the database:
CAT_6k_MT#conf t
Enter configuration commands, one per line. End with CNTL/Z.
CAT_6k_MT(config)#vlan 1241
CAT_6k_MT(config-vlan)#name test
CAT_6k_MT(config-vlan)#exit
% Applying VLAN changes may take few minutes. Please wait...
2. Trying to add the SVI interface for that vlan
CAT_6k_MT(config)#int vlan 1241
CAT_6k_MT(config-if)#no shut
CAT_6k_MT(config-if)#
Oct 14 10:11:04.241 CST: %PM-4-SVI_ADD_CORRESPONDING_L2_VLAN: Vlan 1241 must be added to L2 database in order to be used, do <vlan 1241> from config mode.
Oct 14 10:11:04.257 CST: %LINK-3-UPDOWN: Interface Vlan1241, changed state to down
Then I checked the vlan 1241 is created on the database:
CAT_6k_MT#sh vlan id 1241
VLAN Name Status Ports
1241 VLAN1241 active Po11, Po61
VLAN Type SAID MTU Parent RingNo BridgeNo Stp BrdgMode Trans1 Trans2
1241 enet 101241 1500 - - - - - 0 0
Remote SPAN VLAN
Disabled
Primary Secondary Type Ports
CAT_6k_MT#sh run int vlan 1241
Building configuration...
Current configuration : 41 bytes
interface Vlan1241
no ip address
end
But when I look at the interface vlan is always down/down:
CAT_6k_MT(config-if)#do sh int vlan 1241
Vlan1241 is down, line protocol is down
Hardware is EtherSVI, address is 0016.9c7b.d7c0 (bia 0016.9c7b.d7c0)
MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, loopback not set
Keepalive not supported
ARP type: ARPA, ARP Timeout 04:00:00
Last input never, output never, output hang never
Last clearing of "show interface" counters never
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0
Queueing strategy: fifo
Any ideas reagrding this?
Thanks for your help!

Alex,
Ensure that you have assigned the switch port(s) to VLAN on the switch  side. Also ensure that at least one VLAN port on the switch is connected to the switch or the workstation, and is active.
