permit
c e s
Configure a filter to pass IP packets meeting the filter criteria.
Syntax
permit {ip | ip-protocol-number} {source mask | any | host ip-address} {destination mask |
any | host ip-address} [count [byte] | log] [dscp value] [order] [monitor] [fragments]
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 deny {ip | ip-protocol-number} {source mask | any | host ip-address}
{destination mask | any | host ip-address} command.
Parameters
Defaults
Not configured.
Command Modes
CONFIGURATION-EXTENDED-ACCESS-LIST
Command
History
ip Enter the keyword ip to configure a generic IP access list. The keyword ip
specifies that the access list will permit all IP protocols.
ip-protocol-number
Enter a number from 0 to 255 to permit based on the protocol identified in the
IP protocol header.
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.
destination
Enter the IP address of the network or host to which the packets are sent.
count (OPTIONAL) Enter the keyword count to count packets processed by the
filter.
byte (OPTIONAL) Enter the keyword byte to count bytes processed by the filter.
log (OPTIONAL, E-Series only) Enter the keyword log to enter ACL matches in
the log.
dscp (OPTIONAL) Enter the keyword dcsp to match to the IP DSCP values.
order (OPTIONAL) Enter the keyword order to specify the QoS order of priority
for the ACL entry.
Range: 0-254 (where 0 is the highest priority and 254 is the lowest; lower
order numbers have a higher priority)
Default: If the order keyword is not used, 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
will be applied to the monitored interface. For details, see the section
“Flow-based Monitoring” in the Port Monitoring chapter of the FTOS
Configuration Guide.
fragments Enter the keyword fragments to use ACLs to control packet fragments.
Version 8.3.1.0 Add DSCP value for ACL matching.
Version 8.2.1.0 Allows ACL control of fragmented packets for IP (Layer 3) ACLs.
