Monitoring Statistics IPSec

Sent Packets Dropped

The cumulative total of packets dropped during send processing by all currently and previously active IPSec Phase-2 tunnels. This number should be zero; if not, check for a network problem, check the event log for an internal subsystem failure, or contact Cisco support.

Inbound Authentications

The cumulative total number of inbound individual packet authentications performed by all currently and previously active IPSec Phase-2 tunnels.

Failed Inbound Authentications

The cumulative total of inbound packet authentications that failed, by all currently and previously active IPSec Phase-2 tunnels. Failed authentications could indicate corrupted packets or a potential security attack (“man in the middle”).

Outbound Authentications

The cumulative total of outbound individual packet authentications performed by all currently and previously active IPSec Phase-2 tunnels.

Failed Outbound Authentications

The cumulative total of outbound packet authentications that failed, by all currently and previously active IPSec Phase-2 tunnels. This number should be zero or very small; if not, check the event log for an internal IPSec subsystem problem.

Decryptions

The cumulative total of inbound decryptions performed by all currently and previously active IPSec Phase-2 tunnels.

Failed Decryptions

The cumulative total of inbound decryptions that failed, by all currently and previously active IPSec Phase-2 tunnels. This number should be zero or very small; if not, check for misconfiguration.

Encryptions

The cumulative total of outbound encryptions performed by all currently and previously active IPSec Phase-2 tunnels.

Failed Encryptions

The cumulative total of outbound encryptions that failed, by all currently and previously active IPSec Phase-2 tunnels. This number should be zero or very small; if not, check the event log for an internal IPSec subsystem problem.
