Port Traffic Controls
Guaranteed Minimum Bandwidth (GMB)
For switches covered in this guide, the actual minimum guaranteed bandwidth
allocated for each queue is accurate to +/- six percent of the expected value.
Note For more information on queue configuration and the associated default
minimum bandwidth settings, refer to the chapter titled “Quality of Service
(QoS): Managing Bandwidth More Effectively” in the Advanced Traffic
Management Guide for your switch.
Configuring Guaranteed Minimum Bandwidth for
Outbound Traffic
For any port or group of ports you can configure either the default minimum
bandwidth settings for each outbound priority queue or a customized band-
width allocation. For most applications, ProCurve recommends configuring
GMB with the same values on all ports on the switch so that the outbound
traffic profile is consistent for all outbound traffic. However, there may be
instances where it may be advantageous to configure special profiles on
connections to servers or to the network infrastructure (such as links to
routers, other switches, or to the network core).
