Important:
The mask must contain a contiguous set of one-bits from the least significant bit (LSB). Therefore,
allowed masks are 0, 1, 3, 7, 15, 31, 63, 127, and 255. For example, acceptable wildcards are 0.0.0.3, 0.0.0.255, and
0.0.15.255. A wildcard of 0.0.7.15 is not acceptable since the one-bits are not contiguous.
0.0.15.255. A wildcard of 0.0.7.15 is not acceptable since the one-bits are not contiguous.
eq dest_port
Specifies a single, specific destination TCP port number to be filtered.
dest_port
must be configured to an integer value from 0 to 65535.
gt dest_port
Specifies that all destination TCP port numbers greater than the one specified are to be filtered.
dest_port
must be configured to an integer value from 0 to 65535.
lt dest_port
Specifies that all destination TCP port numbers less than the one specified are to be filtered.
dest_port
must be configured to an integer value from 0 to 65535.
neq dest_port
Specifies that all destination TCP port numbers not equal to the one specified are to be filtered.
dest_port
must be configured to an integer value from 0 to 65535.
Usage
Block IP packets when the source and destination are of interest but for only a limited set of ports.
Important:
The maximum number of rules that can be configured per ACL varies depending on how the ACL is
to be used. For more information, refer to the Engineering Rules appendix in the System Administration Guide. Also
note that “redirect” rules are ignored for ACLs applied to specific subscribers or all subscribers facilitated by a specific
context.

Example
The following command defines a rule that redirects packets to the next hop host at
fe80::c0a8:a04
, the
context with the context ID of
23
, and UDP packets coming from any host are matched:
redirect nexthop fe80::c0a8:a04 context 23 udp any
The following sets the insertion point to before the rule defined above:
before redirect nexthop fe80::c0a8:a04 context 23 udp any
The following command sets the insertion point after the rule defined above:
after redirect nexthop fe80::c0a8:a04 context 23 udp any
The following command deletes the first rule defined above:
no redirect nexthop fe80::c0a8:a04 context 23 udp any
