Commands
permit – assigns a permit filter for IP packets.
permit udp – assigns a permit filter for UDP packets.
permit udp
Configure a filter to pass UDP packets meeting the filter criteria.
Syntax
permit udp {source address mask | any | host ipv6-address} [operator port
[port]] {destination 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 if you know the filter’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 prefix length in the /x format. The range is /0
to /128. The :: notation specifies successive hexadecimal fields of zero.
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 x:x:x:x::x
format. 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 (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 prefix length in the /x format. The range is /0
to /128. The :: notation specifies successive hexadecimal fields of zero.
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.
