Controlling Unknown Frame Distribution
A frame is considered unknown when the LE client does not recognize the
destination MAC address. An unknown frame goes to the broadcast and unknown
server (BUS) for distribution. Setting unknown frame variables helps to limit
unknown frame traffic to the BUS.
To control the distribution of unknown frames, you can specify the following:
• Maximum number of unknown frames the LEC can send.
• Amount of time allowed to send the unknown frames to the BUS.
Setting a Maximum Unknown Frame Count
By default, a LEC can send only one unknown frame to the BUS within a
specified unknown frame time (see the next section, “S
pecifying a Maximum
Unknown Frame Time”). However, you can allow a LEC to send up to 10
unknown frames to the BUS within the maximum unknown frame time.
Using the BCC
To change the maximum unknown frame count value, navigate to the LANE
service record prompt (for example,
box; atm/11/1; lec-service/newyork
) and
enter:
maximum-unknown-frame
value
value is the maximum number of unknown frames (from 1 to 10) that the LEC can
send to the BUS within the maximum unknown frame time.
For example, the following command changes the maximum unknown frame
count to 5:
lec-service/newyork# maximum-unknown-frame 5
lec-service/newyork#
