[port]] [count [byte]] | [log] [monitor]
To remove this lter, you have two choices:
• Use the no seq sequence-number command if you know the lter’s sequence number.
•
Use the no permit udp {source address mask | any | host ipv6-address}
{destination address | any | host ipv6-address} command.
Parameters
source address Enter the IPv6 address of the network or host from which the packets were sent in
the x:x:x:x::x format followed by the prex length in the /x format. The range is /0
to /128. The :: notation species successive hexadecimal elds of zero.
mask Enter a network mask in /prex format (/x).
any Enter the keyword any to specify that all routes are subject to the lter.
host ipv6-address Enter the keyword host followed by the IPv6 address of the host in the x:x:x:x::x

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 port for the port
parameter.)
port port (OPTIONAL) Enter the application layer port number. Enter two port numbers if
using the range logical operand. The range is 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 prex length in the /x format. The range is /0 to /
128. The :: notation species successive hexadecimal elds of zero.
