IBM SC30-3681-08 manual Arp-cache-size, Arp-queue-depth, Arp-response-time, Auto-cong

Con®guring Forum LE Clients

Valid Values:

An integer number of seconds in the range of 10 to 300.

Default Value:

300

Example:

LEC Config> set arp-aging-time 200

arp-cache-size

Sets the number of entries in the ARP cache. The size of the ARP cache limits the number of simultaneous data direct VCCs. Larger ARP caches require more memory, but permit the client to simultaneously converse with a larger number of destinations.

Valid Values:

An integer number in the range of 10 to 65535.

Default Value:

5000

Example:

LEC Config> set arp-cache-size 10

arp-queue-depth

Sets the maximum number of queued frames per ARP cache entry. The LEC enqueues frames when switching the data path from the Multicast Send VCC to a Data Direct VCC. Frames passed to the LEC for transmission will be discarded if the queue is full. A larger queue requires more memory, but results in fewer discarded frames during the data path switch.

Valid Values:

An integer number in the range of 0 to 10.

Default Value:

5

Example:

LEC Config> set arp-queue-depth 10

arp-response-time

Sets expected ARP response time. This value controls how frequently an unanswered LE ARP request is retried. Larger values result in fewer LE ARPs, which causes less traffic and possibly increase the amount of time before a Data Direct VCC is established.

Valid Values:

An integer number of seconds in the range of 1 to 30.

Default Value:

1 second

Example:

LEC Config> set arp-response-time 20

auto-con®g

Speci®es whether this LEC uses LECS auto-con®g mode. Specify YES or NO. The LEC may contact the LECS to obtain the address of its LES and various other con®guration parameters.
