Quality of Service: Managing Bandwidth More Effectively
QoS Queue Configuration
Note For more information on configuring GMB, refer to the chapter titled “Port
Traffic Controls” in the Management and Configuration Guide.
Minimum Guaranteed Bandwidth with 8 Queues
When 10 Mbps ports on an 8200zl or 5400zl switch are configured in QoS for
eight outbound queues (the default), and the guaranteed minimum bandwidth
is set for 5 Mbps or less for a given queue, then packets in the lower-priority
queues may be discarded on ports that are oversubscribed for extended
periods of time. If the oversubscription cannot be corrected, HP recommends
reconfiguring the switch to operate with four outbound queues. The command
to do this is:
HPswitch(config)# qos queue-config 4-queues
This issue applies to 8200zl and 5400zl switch operating with any of the
following modules installed.
