permit udp
To pass UDP packets meeting the filter criteria, configure a filter.
Syntax
permit udp {
source mask
| any | host
ip-address
} [
operator port
[
port
]]
{
destination mask
| any | host
ip-address
} [dscp] [
operator port
[
port
]] [count
[byte] [order] [fragments] [monitor [
session-ID
]] [no-drop]
To remove this filter, you have two choices:
•
Use the
no seq
sequence-number
command if you know the filter’s sequence number.
•
Use the
no permit udp {
source mask
| any | host
ip-address
} {
destination mask
|
any | host
ip-address
command.
Parameters
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
and then enter the IP address to specify a host IP address.
dscp
Enter the keyword
dscp
to deny a packet based on the DSCP value. The range is from 0
to 63.
operator
(OPTIONAL) Enter one of the following logical operand:
•
eq
= equal to
•
neq
= not equal to
•
gt
= greater than
•
lt
= less than
•
range
= inclusive range of ports (you must specify two ports for the
port
parameter)
port port
Enter the application layer port number. Enter two port numbers if you are using the
range
logical operand. The range is 0 to 65535.
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.
order
(OPTIONAL) Enter the keyword
order
to specify the QoS priority for the ACL entry.
The range is from 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).
fragments
Enter the keyword
fragments
to use ACLs to control packet fragments.
monitor
(OPTIONAL) Enter the keyword
monitor
then the session–ID to describe the traffic
that you want to monitor and the ACL in which you are creating the rule is applied to the
monitored interface. The session–ID range is from 0 to 65535. For more information, see
