Hello, maybe this helps you for your cisco device: Configuring the IPSec SA Idle Timer Globally To configure the IPSec SA idle timer globally, enter the crypto ipsec security-association idle-time command in global configuration mode as follows: Router(config)# crypto ipsec security-association idle-time seconds In this command, seconds specifies the time, in seconds, that the idle timer will allow an inactive peer to maintain an SA. Valid values range from 60 to 86400. Configuring the IPSec SA Idle Timer per Crypto Map To configure the IPSec SA idle timer for a specified crypto map, use the set security-association idle-time command within a crypto map configuration beginning in global configuration mode : Command Purpose Step 1 Router(config)# crypto map map-name seq-number ipsec-isakmp Creates or modifies a crypto map entry and enters crypto map configuration mode. • map-name—Name that identifies the crypto map set. • seq-number—Sequence number you assign to the crypto map entry. Lower values have higher priority. • ipsec-isakmp—Indicates that IKE will be used to establish the IPSec security associations. Step 2 Router(config-crypto-map)# set security-association idle-time seconds Configures the IPSec SA idle timer. • seconds—Time, in seconds, that the idle timer will allow an inactive peer to maintain an SA. Valid values range from 60 to 86400.
