must be a string from 1 through 15 characters in length.
Apply this rule definition only to packets in the downlink (from the Mobile Node) direction.
Default: packets are not logged.
Indicates all packets which match the filter are to be logged.
Indicates all packets which match the filter are to be logged.
The IP address(es) form which the packet originated.
This option is used to filter all packets from a specific IP address or a group of IP addresses.
When specifying a group of addresses, the initial address is configured using this option. The range can then

This option is used in conjunction with the
option to specify a group of addresses for
which packets are to be filtered.
The mask must be entered as a complement:
The mask must be entered as a complement:
Zero-bits in this parameter mean that the corresponding bits configured for the
parameter must be identical.
One-bits in this parameter mean that the corresponding bits configured for the
parameter must be ignored.
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.
Usage
Define a rule definition when any packet from the IP addresses which fall into the group of addresses
matching the IP address masking. This allows the reduction of filtering rule definitions as it does not require a
rule definition for each source and destination pair.

Important:
A maximum of 16 rule definitions can be configured per ACL.
