FWSM and vlans

It is my understanding that the FWSM for the 6500 series switches uses a 6 port Etherchannel on the backplane to communicate with the 6500 series switch.

Can you shutdown vlan1 on the switch and still communicate with the FWSM? I was under the impression that you could not (although I am looking at a config with it shutdown)

- This is correct.

- shut down the vlan on the switch? If you shut the vlan down on the switch, even if you pushed the vlan down to the FWSM the vlan will not show up on the FWSM.  You can still session into the FWSM from the switch.  It does a telnet to 127.0.0.11 if the module is in slot 1 and 127.0.0.22 if the module is on slot 2 etc.
