Received Bytes
The cumulative total of bytes (octets) received by all currently and previously active IPSec Phase-2
tunnels, before decompression. In other words, total bytes of IPSec-only data received by the IPSec
subsystem, before decompressing the IPSec payload.
Sent Bytes
The cumulative total of bytes (octets) sent by all currently and previously active IPSec Phase-2 tunnels,
after compression. In other words, total bytes of IPSec-only data sent by the IPSec subsystem, after
compressing the IPSec payload.
Received Packets
The cumulative total of packets received by all currently and previously active IPSec Phase-2 tunnels.
Sent Packets
The cumulative total of packets sent by all currently and previously active IPSec Phase-2 tunnels.
Received Packets Dropped
The cumulative total of packets dropped during receive processing by all currently and previously active
IPSec Phase-2 tunnels, excluding packets dropped due to anti-replay processing. If there is a problem
with the content of a packet, the system drops the packet. This number should be zero or very small; if
not, check for misconfiguration.
Received Packets Dropped (Anti-Replay)
The cumulative total of packets dropped during receive processing due to anti-replay errors, by all
currently and previously active IPSec Phase-2 tunnels. If the sequence number of a packet is a duplicate
or out of bounds, there may be a faulty network or a security breach, and the system drops the packet.
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”).
