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 This log-message is generated whenever a packet, traversing the

of security policy: router or destined to the router itself, is dropped by the ﬁrewall

because it violates the expected conditions.

4.dropped - invalid This log-message is generated whenever a packet, traversing the

checksum:router or destined to the router itself, is dropped because of invalid IP

checksum.

5.dropped - invalid This log-message is generated whenever a packet, traversing the

data length: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-	This log-message is generated whenever a packet, traversing the
mented packet:	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 This log-message is generated whenever a packet traversing the

fragment:	router is dropped because the packet cannot be sent without frag-
	mentation, but the do not fragment bit is set.

8.dropped - no route This log-message is generated whenever a packet, traversing the

found:	router or destined to the router itself, is dropped because no route is
	found to forward the packet.

9.dropped - invalid IP This log-message is generated whenever a packet, traversing the

version:	router or destined to the router itself, is dropped because the IP ver-
	sion is not 4.

10.dropped - possi- This log-message is generated whenever a packet, traversing the

ble land attack: 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 This log-message is generated whenever a SYN packet destined to

detected:	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 This log-message is generated whenever TCP packets destined to

attack - packets	the router's telnet management interface are dropped due to over-
dropped:	whelming receive data.
