I believe that "set security-association" is a per-crypto-map override of the global "lifetime" command.

>From the doc cd:

"To override (for a particular crypto map entry) the global lifetime value, which is used when negotiating IP Security security associations, use the set security-association lifetime command in crypto map configuration mode."

Hi, Can someone tell me what's the difference between the " set
security-association lifetime seconds 1800" under crypto map config and
the " lifetime 1800" under crypto isakmp policy config? thanks! I know
the the first one is the lifetime of a security association but not sure
what the 2nd is for and if they have any corelation. thanks Ellie
