Bridging Service
Traffic Filters
Traffic Filters
Traffic filters apply to all incoming bridge traffic across the circuit group.
You can, if you wish, construct up to 31 filters for each bridging circuit group.
Conceptually a filter consists of a rule which identifies packets to be filtered,
an action to take upon receipt of a frame that meets the conditions of the
rule, and a precedence that identifies which action to take in the event of a
frame that meets the conditions of more than one rule. A filter rule consists
of three entities:
A specified field (or fields) in the frame header
A value (or range of values) associated with the field
An operator which specifies the relationship between field and value.
A filter operator may take one of three values: ignore, match, or don't match.
A filter precedence is designated by a decimal value from 1 to 31; the higher
the value, the greater the precedence.
