Usage
Information
The
order
option is relevant in the context of the Policy QoS feature only. See the “Quality of
Service” chapter of the
FTOS Configuration Guide
for more information.
When you use the
log
option, CP processor logs details about the packets that match. Depending on
how many packets match the
log
entry and at what rate, the CP may become busy as it has to log these
packets’ details.
The
monitor
option is relevant in the context of the flow-based monitoring feature only. See
.
permit tcp
c e s
Configure a filter to pass TCP packets meeting the filter criteria.
Syntax
permit

} [

To remove this filter, you have two choices:
•
Use the
no
seq
sequence-number
command syntax if you know the filter’s sequence number
or
•
Use the
no

} {

} command.
Parameters
Version 7.4.1.0
Added support for non-contiguous mask and added the
monitor
option.
Version 6.5.10
Expanded to include the optional QoS
order
priority for the ACL entry.
Note:
When ACL logging and byte counters are configured simultaneously, byte counters
may display an incorrect value. Configure packet counters with logging instead.
source
Enter the IP address of the network or host from which the packets were sent.
mask
Enter a network mask in /prefix format (/x) or A.B.C.D. The mask, when specified in
A.B.C.D format, may be either contiguous or non-contiguous.
any
Enter the keyword
any
to specify that all routes are subject to the filter.
host
ip-address
Enter the keyword
host
followed by the IP address to specify a host IP address.
bit
Enter a flag or combination of bits:
ack:
acknowledgement field
fin
: finish (no more data from the user)
psh:
push function
rst:
reset the connection
syn:
synchronize sequence numbers
urg:
urgent field
dscp
Enter this keyword to deny a packet based on DSCP value.
