CABLETRON 9000162 Channel relay module
The port-fair keyword is mutually exclusive with the link and distribute keywords. When port-fair is specified, the CCAG SAP queues and schedulers on each CCA will receive a portion of the defined parameters in the QoS and scheduler policies. The portion is per-port basis and equals the value configured divided by the total number of active members within the CCAG. The following equation may be used to determine the actual ratio: Per-port-parameter-value = (1 / total-active-CCA) * policy-parameter-value
This command defines a maximum forwarding
rate for each CCA member within the CCAG. Support of setting a maximum CCA forwarding rate is provided to prevent overrunning the ingress forwarding plane when sub-line rate ingress features are enabled. The primary ingress feature requiring this support is dual ingress access queuing. When dual ingress queuing is enabled on cross connect SAPs, the CCA forwarding rate should be limited to a rate that prevents packet loss due to ingress forwarding congestion. The specified limit is applied to the aggregate alpha and beta path bandwidth. The no form of the command removes CCA bandwidth rate limiting. Parameters kilobits-per-second — Defines the maximum CCA rate in kilobits per second. The actual Kilobits per second rate is rounded up to the nearest 50Mbps increment.
