SECURITY > FILTERS

Configure the filter characteristics from this menu.

SECURITY > FILTERS > FILTER DEFINES

The unit can filter packets based on certain parameters within the packet. The method used by the unit

allows the highest flexibility for defining filters and assigning them to a PVC or PPP link. The filters are

set up in two steps: (1) defining the filter types, and (2) applying them to a list under the PVC or PPP

configuration. This menu is used to define the individual filter defines based on packet type.

SECURITY > FILTERS > FILTER DEFINES > MAC FILTER DEFINES

The MAC filter is applied to bridge packets only. Bridge packets which are forwarded by the bridge

functionality of the unit are defined here. Up to 32 MAC defines can be specified.

The Filter Defines option applies to both Frame Relay and PPP operation.

NUM

Indicates the entry number in the MAC Filter Defines table.

NAME

Identifies the filter entry. Default is no entry in NAME field.

FILTER TYPE

Specifies a NORMAL or DEBUG filter. When a NORMAL filer is applied to an interface, traffic is blocked

or forwarded according to the filter. When a

DEBUG filter is applied, packets that match the filter are

documented without affecting traffic flow. (Use the

DEBUG filter with the Syslog or Terminal Mode

logging to view the packet contents.)

SRC ADDR

48-bit MAC source address used for comparison. Values are in hexadecimal format. Default is

00:00:00:00:00:00.

SRC MASK

Bits in the MAC source address which are compared. Values are in hexadecimal format. Default is

00:00:00:00:00:00.

DEST ADDR

48-bit MAC destination address used for comparison. Values are in hexadecimal format. Default is

00:00:00:00:00:00.
