Wisms- hot swap to 2nd host?

We are going through recovery scenarios for wireless controllers and this question came up.

Can you take a WiSM from one 6500 host and slap it another provided the VLAN and etherchanneling are already set up? Or would the WiSM itself need a partial or full reconfiguration upon re-install?

Re: Wisms- hot swap to 2nd host?

You can't. As you pointed out, the chassis will have to recognize the card to enable the etherchannel ports. Plus, by default, when you insert the module to a slot, the chassis DISABLES the power to that slot.

The only thing I can think of is prepare a text file with slot number blanked out. When you insert the WiSM into the slot, fill in the blanks and cut-and-paste.

Hope this helps.

Thanks for the reply. So pretty much everything can be pre-config'd EXCEPT the etherchannel, then re-enable power, etc.

Will the WiSM's maintain their config info while disconnected?

WiSM config is stored in NVRAM, it will keep it while offline
