-port_pair_off
Checks upper-level protocol port numbers without switching
the port numbers of the source and destination protocols.
Before specifying the
-port_pair
check, set the synchronized
check function for IP address and upper level protocol port
number to OFF (
-pair_synchronized_off
).
Define 6 (TCP) or 17 (UDP) for a -protocol parameter when this
parameter is specified. The set value of this parameter is
disabled when a -protocol parameter is undefined or when 6
(TCP) or 17 (UDP) is not defined.
Default:
-port_pair
-port_source <Port No.> [-<Port No.>]
Description:
This parameter specifies the port number of an upper-level
source protocol. One port number is specified as
-port_source
<Port No.>
. A port number range is specified as
-port_source
<lower limit Port No.>
-
<upper limit Port No.>
. When both
source and destination upper protocol port numbers are set
under one condition, set so that the specified upper protocol
port numbers do not overlap. If they overlap, set an upper
protocol port number’s pair switch as port_pair_off.
Define 6 (TCP) or 17 (UDP) for a -protocol parameter when this
parameter is specified. The set value of this parameter is
disabled when a -protocol parameter is undefined or when 6
(TCP) or 17 (UDP) is not defined.
Default:
None (source port numbers are not flow detection conditions).
Range of value:
0-65535
-port_destination <Port No.> [-<Port No.>]
Description:
This parameter specifies the port number of an upper-level
destination protocol. One port number is specified as
-port_source <Port No.>
. A range is specified as
-port_source
<lower limit Port No.>
-
<upper limit Port No.>
. When both
destination and source upper protocol port numbers are set
under one condition, set so that the specified upper protocol
port numbers do not overlap. If they overlap, set an upper
protocol port number’s pair switch as port_pair_off.
Default:
None.
Range of value:
0-65535
{ -pair_synchronized_off | -pair_synchronized }
Description:
This parameter specifies a synchronized check of IP addresses
and upper-level protocol port numbers.
-pair_synchronized_off
Checks the source and the destination IP addresses, and
upper-level source and destination protocol port numbers
without simultaneously switching the values. Note that the IP
and/or port check will follow the routine of
-ip_ pair
and/or
-port_pair
if either or both of those parameters are specified.
