IBM SC30-3681-08 manual ¯ush-timeout, Forward-delay, Forward-disconnect-timeout

Con®guring Forum LE Clients

¯ush-timeout

Sets the ¯ush timeout. This is the time limit to wait to receive the

LE_FLUSH_RESPONSE after the LE_FLUSH_REQUEST has been sent before taking recovery action. During recovery, any queued frames are dropped and a new ¯ush request is sent.

When switching from the multicast send to a data direct data path, the client sends a ¯ush request over the multicast send VCC. Until a ¯ush response is received, or until the path switch delay expires, frames are queued for the destination.

Valid Values:

An integer number of seconds in the range of 1 to 4.

Default Value:

4

Example:

LEC Config> set flush-timeout 3

forward-delay

Sets the forward delay. Entries in the LE ARP cache must be periodically re-veri®ed. The forward delay time is the maximum amount of time a remote entry may remain in the cache during a network topology change. Larger aging times may result in stale (invalid) entries, but also cause less re-veri®cation traffic.

Valid Values:

An integer number of seconds in the range of 4 to 30.

Default Value:

15

Example:

LEC Config> set forward-delay 10

forward-disconnect-timeout

This parameter sets the amount of time that a LEC will wait after losing its last Multicast Forward VCC from the BUS before returning to the initial state. This delay permits the BUS to attempt to reconnect to the client without returning to the initial state.

Valid Values:

10 - 300 seconds

Default Value:

60

frame-size

Sets the frame size.

The value speci®ed for frame-size must be equal to or less than the value speci®ed for ATM max-frame using the ATM INTERFACE>set max-framecommand as described on page 282.

Valid Values:
