Removing existing Crypto Map on a router

Can anyone provide me the "proper" sequence to remove a existing crypto map on a point to point vpn from my router? I have tried removing each line first individually however; each time I do that I loose access to my router and have to reload. Yes, I am accessing via the public serial's IP. I've also tried removing the filter which locked me out and tried removing the transform set. It won't let me do that since it is applied to the crypto map.

crypto map cm-cryptomap 4 ipsec-isakmp

set peer

set security-association lifetime kilobytes 10000

set security-association lifetime seconds 86400

set transform-set cm-transformset-4

match address 105

access-list 105 permit ip

crypto ipsec transform-set cm-transformset-4 esp-des esp-md5-hmac

Any suggestions?

My last option is to tftp a modified version to startup, but I'm hoping that will be a last resort.

Re: Removing existing Crypto Map on a router

Remove the crypto map off the public serial interface, then you can make as many changes as you like without fear of locking yourself out. When all your changes are complete, re-apply the crypto map to the serial interface.

> interface Serial x

> no crypto map cm-cryptomap
