Cisco Meraki products, by default, use alifetime of 8 hours (28800 seconds) for both IKE phase 1 and IKE phase 2.

When an encrypted card is inserted, the current configuration Phase 1 negotiates a security association (a key) between two releases in which each feature is supported, see the feature information table.
