c e s
Configure a filter to drop UDP packets meeting the filter criteria.

address | any | host ipv6-address} [operator port [port]] [count [byte]] | [log] [monitor]
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 udp {source address mask | any | host ipv6-address} {destination
address | any | host ipv6-address} command.
Parameters

ACCESS-LIST
source address

in the
x:x:x:x::x format followed by the prefix length in the /x format.
Range: /0 to /128

mask Enter a network mask in /prefix format (/x).
any Enter the keyword any to specify that all routes are subject to the filter.
host ipv6-address Enter the keyword host followed by the IPv6 address of the host in the

The
:: notation specifies successive hexadecimal fields of zero
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

(OPTIONAL) Enter the application layer port number. Enter two port numbers
if using the
range logical operand.
Range: 0 to 65535
destination address
Enter the IPv6 address of the network or host to which the packets are sent in
the
x:x:x:x::x format followed by the prefix length in the /x format.
Range: /0 to /128
The
:: notation specifies successive hexadecimal fields of zero.
