This object counts the number of IPsec Security Associations (SAs) currently in the "larval" state, meaning they are still being negotiated and have not yet become fully established. Admins watch this counter because a persistently high or growing larval count can indicate IKE negotiation problems, such as mismatched proposals or an unreachable peer, that are preventing tunnels from coming up. For example, if snsIPSECStatsSADLarval stays elevated instead of dropping to zero, the admin should check the IKE phase 1/2 negotiation logs for a stuck or failing tunnel.
