ExtremeWare Software 7.3.0 Command Reference Guide 1715
configure qosprofile min-bps
configure qosprofile <qosprofile> min-bps <bps> [k | m]
max-bps <bps> [k | m] {priority <level>} [ports <portlist> |
multilink <multilink name>]
Description
Modifies the default QoS profile parameters for T1 and E1 modules.
Syntax Description
Default
• Minimum bandwidth—0 Kbps
• Maximum bandwidth—1536 Kbps
• Priority—low
Usage Guidelines
This command sets the software egress QoS for T1 and E1 modules, using units of bps of bandwidth,
instead of percentages of bandwidth.
For WAN QoS only two priority levels are available, low and high. Software queues are scheduled
based on priority, minimum bandwidth, and maximum bandwidth. Only one queue can have high
priority.
The high priority queue is flushed on every scheduling round. Minimum bandwidth is ignored for this
queue. Throughput is policed based on the maximum bandwidth value. Policing prevents packets from
entering a queue that is receiving traffic from the backplane too fast. The remaining bandwidth is
shared by all other queues based on the minimum bandwidth setting of each queue. In other words, the
high priority queue takes up all the bandwidth up to its
max-bps
setting, while the low priority queues
share all the remaining bandwidth.
qosprofile Specifies a QoS profile name.
min-bps Specifies a minimum bandwidth for this queue. The default setting is 0.
k Specifies Kbps.
m Specifies Mbps.
max-bps Specifies the maximum bandwidth this queue is permitted to use. The default
setting is 1536 Kbps.
level Specifies a service priority setting. Settings are low and high. The default
setting is low. Available in egress mode only.
portlist Specifies a list of ports or slots and ports to which the parameters apply. May
be in the form 1, 2, 3-5, 2:5, 2:6-2:8.
multilink name Specifies a multilink.
