Table 176 IPSec Logs
LOG MESSAGE DESCRIPTION
Discard REPLAY packet
The router received and discarded a packet with an incorrect
sequence number.
Inbound packet
authentication failed
The router received a packet that has been altered. A third party may
have altered or tampered with the packet.
Receive IPSec packet,
but no corresponding
tunnel exists
The router dropped an inbound packet for which SPI could not find a
corresponding phase 2 SA.
Rule <%d> idle time out,
disconnect
The router dropped a connection that had outbound traffic and no
inbound traffic for a certain time period. You can use the "ipsec timer
chk_conn" CI command to set the time period. The default value is 2
minutes.
WAN IP changed to <IP>
The router dropped all connections with the “MyIP” configured as
“0.0.0.0” when the WAN IP address changed.
Table 177 IKE Logs
LOG MESSAGE DESCRIPTION
Active connection allowed
exceeded
The IKE process for a new connection failed because the limit
of simultaneous phase 2 SAs has been reached.
Start Phase 2: Quick Mode
Phase 2 Quick Mode has started.
Verifying Remote ID failed:
The connection failed during IKE phase 2 because the router
and the peer’s Local/Remote Addresses don’t match.
Verifying Local ID failed:
The connection failed during IKE phase 2 because the router
and the peer’s Local/Remote Addresses don’t match.
IKE Packet Retransmit
The router retransmitted the last packet sent because there
was no response from the peer.
Failed to send IKE Packet
An Ethernet error stopped the router from sending IKE
packets.
Too many errors! Deleting SA
An SA was deleted because there were too many errors.
Phase 1 IKE SA process done
The phase 1 IKE SA process has been completed.
Duplicate requests with the
same cookie
The router received multiple requests from the same peer
while still processing the first IKE packet from the peer.
IKE Negotiation is in process
The router has already started negotiating with the peer for
the connection, but the IKE process has not finished yet.
No proposal chosen
Phase 1 or phase 2 parameters don’t match. Please check all
protocols / settings. Ex. One device being configured for
3DES and the other being configured for DES causes the
connection to fail.
Local / remote IPs of
incoming request conflict
with rule <%d>
The security gateway is set to “0.0.0.0” and the router used
the peer’s “Local Address” as the router’s “Remote Address”.
This information conflicted with static rule #d; thus the
connection is not allowed.
