packet-too-big count
parameter-problem count
time-exceeded count
port-unreachable count
The ICMP packets cannot be filtered using mirroring ACL.
dscp Enter the keyword dscp to deny a packet based on the DSCP value. The range is 0 to
63.
message-type (OPTIONAL) Enter an ICMP message type, either with the type (and code, if necessary)
numbers or with the name of the message type. The range is 0 to 255 for ICMP type and
0 to 255 for ICMP code.
count (OPTIONAL) Enter the keyword count to count packets the filter processes.
byte (OPTIONAL) Enter the keyword byte to count bytes the filter processes.
log (OPTIONAL, E-Series only) Enter the keyword log to have the information kept in an
ACL log file.
order (OPTIONAL) Enter the keyword order to specify the QoS priority for the ACL entry.
The range is 0 to 254 (where 0 is the highest priority and 254 is the lowest; lower-order
numbers have a higher priority). If you do not use the keyword order, the ACLs have the
lowest order by default (255).
monitor (OPTIONAL) Enter the keyword monitor when the rule is describing the traffic that you
want to monitor and the ACL in which you are creating the rule is applied to the
monitored interface.
NOTE: For more information, refer to the Flow-based Monitoring section in
the Port Monitoring chapter of the FTOS Configuration Guide .
fragments Enter the keyword fragments to use ACLs to control packet fragments.
no-drop Enter the keywords no-drop to match only the forwarded packets.
Defaults Not configured.
