Setting the Path Switching Delay
The path switching delay specifies the amount of time that the LEC waits after
sending a frame over an existing VCC before it switches to a new VCC (this
applies to multicast and data direct VCCs).
You can use the path switching delay parameter to bypass the flush protocol.
When you disable the flush protocol, the data for a specific MAC address
automatically begins flowing over a new VCC when the path switching delay time
elapses. (For instructions on disabling the flush protocol, see “Modifying Flush
Protocol Variables” on page 8-44.)
By default, the LEC waits a maximum of 6 seconds after sending a frame over an
existing VCC before it switches to a new VCC. However, you can set the path
switching delay to a value from 1 to 8 seconds.
Using the BCC
To change the path switching delay, navigate to the LANE service record prompt
(for example,
box; atm/11/1; lec-service/newyork
) and enter:
path-switching-delay
<value>
value
is the number of seconds (from 1 to 8) that you want the LEC to wait after
sending a frame over an existing VCC before switching to a new VCC.
For example, the following command changes the path switching delay to 8
seconds:
lec-service/newyork# path-switching-delay 8
lec-service/newyork#
