2316 ExtremeWare 7.7 Command Reference Guide
PoS Commands—BlackDiamond Switch Only
configure red min-threshold ports
configure red min-threshold <percent> ports <portlist>
Description
Configures the minimum queue length threshold for RED operation on the specified PoS ports.
Syntax Description
Default
By default,
min-threshold
is 10% for PoS ports.
Usage Guidelines
When this threshold is exceeded, the RED algorithm is activated. Currently, the command is only
applicable to PoS ports. The
ports
keyword allows the threshold parameter to be configured on a
PoS-port basis. The min-threshold is specified as a percentage, where the
percent
parameter is an integer
in the range [1–100]. For PoS ports, the minimum threshold is a percentage of 1000 packet buffers, and
the maximum threshold is set to minimum ((3 * minimum threshold buffers), maximum available
buffers). The settings for both the minimum and maximum thresholds, in terms of number of buffers,
are displayed by the
show ports info
command.
Example
The following command configures minimum queue length threshold of 50 for port 1 of the PoS
module installed in slot 8 of the BlackDiamond switch:
configure red min-threshold 50 port 8:1
History
This command was first available in an ExtremeWare IP Technology Services Release based on
