ip access-list extended — creates an extended ACL. permit — assigns a permit filter for IP packets. permit udp — assigns a permit filter for UDP packets.

permit udp

To pass UDP packets meeting the filter criteria, configure a filter.

Syntaxpermit udp {source mask any host ip-address} [operator port [port]] {destination mask any host ip-address} [dscp] [operator port [port]] [count [byte] [order] [fragments]

To remove this filter, you have two choices:

•Use the no seq sequence-numbercommand if you know the filter’s sequence number.

•Use the no permit udp {source mask any host ip-address} {destination mask any host ip-addresscommand.

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)
