permit tcp
Configure a filter to pass TCP packets that match the filter criteria.
Syntax
permit tcp {source address mask | any | host ipv6-address}
[operator port [port]] {destination address | any | host ipv6-
address} [bit] [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 tcp {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.

• eq = equal to
• neq = not equal to
• gt = greater than
