List of Links

 

Specifies the links associated with the preceding link action

 

 

 

parameters in this table. When Passlist (PL) is specified, the

 

 

 

associated listed links pass the frame and the unlisted links

 

 

 

block it. Conversely, when Blocklist (BL) is specified, the

 

 

 

associated listed links block the frame and the unlisted links

 

 

 

pass it.

Parameter

 

Action

 

Value

 

 

 

 

 

 

Pass (P)

Look in the MAC Address Filter Table for an entry with a matching

 

 

MAC frame address and perform the filtering action specified by

 

 

this entry. If no matching MAC frame address is found, pass the

 

 

frame.

 

 

 

 

 

Block (B)

Look in the MAC Address Filter Table for an entry with a matching

 

 

MAC frame address and perform the filtering action specified by

 

 

this entry. If no matching MAC frame address is found, block the

 

 

frame.

 

 

 

 

 

None (N)

No filtering to be performed; pass the frame.

What Happens

 

 

 

 

 

 

When filtering is performed, the system checks the Bridge Link Table of the bridge

During Filtering

link involved with the frame to see if the MAC Address Filtering Action parameter is

 

configured to disable all filtering on that bridge link. Figure 30 shows the process

 

involved in MAC Address filtering.

If the parameter is configured to disable filtering (NONE selected), then the frame is allowed to pass and no filtering is applied.

If the parameter is configured with another value, either PASS or BLOCK, this signifies that the MAC Address Filter Table is to be checked to determine whether filtering action is to be performed. In this situation, the frame is checked to see if a match occurs between the MAC address in the frame and an address contained in an entry in the MAC Address Filter Table.
