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 when any packet from the IP addresses which fall into the group of addresses matching the IP
address masking. This allows the reduction of redirect rules as it does not require a rule for each source and
destination pair.

Important:
The maximum number of rules that can be configured per ACL varies depending on how the ACL is
to be used. Refer to the Engineering Rules appendix located in the Administration and Configuration Guide for more
information. Also note that ―redirect‖ rules are ignored for ACLs applied to specific subscribers or all subscribers
facilitated by a specific context.
