Access-related Log Messages
1. permitted: This log-message is generated whenever a packet is allowed to
traverse router-interfaces or allowed to access the router itself.
2. attempt: This log-message is generated whenever a packet attempts to
traverse router-interfaces or attempts to access the router itself.
3. dropped - violation
of security policy: This log-message is generated whenever a packet, traversing the
router or destined to the router itself, is dropped by the firewall
because it violates the expected conditions.
4. dropped - invalid
checksum: This log-message is generated whenever a packet, traversing the
router or destined to the router itself, is dropped because of invalid IP
checksum.
5. dropped - invalid
data length: This log-message is generated whenever a packet, traversing the
router or destined to the router itself, is dropped because the IP length
is greater than the received packet length or if the length is too small
for an IP packet.
6. dropped - frag-
mented packet: This log-message is generated whenever a packet, traversing the
router, is dropped because it is fragmented, stateful inspection is
turned ON on the packet's transmit or receive interface, and deny-
fragment option is enabled.
7. dropped - cannot
fragment: This log-message is generated whenever a packet traversing the
router is dropped because the packet cannot be sent without frag-
mentation, but the do not fragment bit is set.
8. dropped - no route
found: This log-message is generated whenever a packet, traversing the
router or destined to the router itself, is dropped because no route is
found to forward the packet.
9. dropped - invalid IP
version: This log-message is generated whenever a packet, traversing the
router or destined to the router itself, is dropped because the IP ver-
sion is not 4.
10. dropped - possi-
ble land attack: This log-message is generated whenever a packet, traversing the
router or destined to the router itself, is dropped because the packet is
TCP/UDP packet and source IP Address and source port equals the
destination IP Address and destination port.
11. TCP SYN flood
detected: This log-message is generated whenever a SYN packet destined to
the router's management interface is dropped because the number of
SYN-sent and SYN-receives exceeds one half the number of allow-
able connections in the router.
12. Telnet receive DoS
attack - packets
dropped: This log-message is generated whenever TCP packets destined to
the router's telnet management interface are dropped due to over-
whelming receive data.
