I have been tasked with removing several redundant transfrom-sets from some cisco router2router IPSEC configurations. Can transform sets be removed "on the fly", without disturbing the Security Association (if it is already built)?. Can someone give me the recommended procedure for removing transform-sets and then making a crypto map use a new transform-set?
hi, there is no way to remove a transform set "in the fly".
If you try it, there is an error message at the promtp who says : "first disable de transform set from the crypto map".
so you must first disable the crypto map applied to the interface.
then disable de "set transform set" from the crypto map, and then you must edit or create the new transform set, deleting the old one or editing the new one.
