ExtremeWare 7.7 Command Reference Guide 2259
enable diffserv ingress replacement ports
enable diffserv ingress replacement [high-priority | low-priority |
low-and-high-priority] ports [<portlist> | all] {<Ingress QOS profile>}
Description
Enables the optional overwriting of the DiffServ code point portion of the (IP TOS) field for ingress
traffic.
Syntax Description
Default
Disabled
Usage Guidelines
If you enable DiffServ ingress replacement before you configure a code point, the default code point is
0. To configure a code point for both the low-priority and high-priority traffic, use the command:
configure diffserv ingress replacement low-priority code-point <number> high-priority
code-point <number> ports [<portlist> | all] {<Ingress QOS profile>}
You can enable DiffServ ingress replacement for:
• Both high-priority and low-priority traffic on the specified ports or each ingress QoS profile on the
specified ports.
• Either high-priority or low-priority traffic for all ingress QoS profiles on the specified ports or a
selected ingress QoS profile on the specified ports.
The
“3”
series I/O modules support eight ingress QoS profiles (IQP1 - IQP8).
Example
The following command enables low-priority DiffServ replacement for all “3” series ports in all ingress
QoS profiles:
enable diffserv ingress replacement low-priority ports all
