High Density Gigabit Ethernet Commands
configure diffserv ingress replacement ports
configure diffserv ingress replacement low-priority code-point <number>
high-priority code-point <number> ports [<portlist> | all] {<Ingress QOS
profile>}
Description
Configures the optional overwriting of the DiffServ code point portion of the IP TOS field for ingress
traffic.
Syntax Description
Default
The default values for both the low-priority and high-priority code points are 0.
Usage Guidelines
This command allows the overwriting of the upper 6 bits of the IP TOS field. The lower 2 bits of the
TOS field passes through unchanged.
You can specify different code point values for both high-priority (below the committed-rate) and
low-priority (above the committed-rate) traffic on each port or each ingress QoS profile on each port.
DiffServ ingress replacement is only done on IP Ethernet II (Ethertype) encapsulated frames. Frames
that are IPX, LLC, or SNAP encapsulated are passed through with no DiffServ code point alterations.
You must enable low-priority and high-priority DiffServ ingress replacement on the specified ports
before you can overwrite low-priority or high priority traffic. To enable low-priority and high-priority
DiffServ ingress replacement, use the command:
enable diffserv ingress replacement [low-priority | high-priority] ports [<portlist> |
all] {<Ingress QOS profile>}
The
“3”
series I/O modules support eight ingress QoS profiles (IQP1 - IQP8).
If you do not specify an ingress QoS profile, all ingress QoS profiles for the indicated ports are affected.
low priority code-point number Specifies the low-priority DiffServ code point (IP TOS) value to use to
overwrite low-priority ingress traffic. The default is 0. The range is 0 to 63.
high priority code-point number Specifies the high-priority DiffServ code point (IP TOS) value to use to
overwrite high-priority ingress traffic. The default is 0. The range is 0 to 63.
portlist Specifies one or more slots and ports. May be in the form 2:*, 2:5, 2:6-2:8.
all Specifies all
“3”
series ports.
Ingress QoS profile Specifies an ingress QoS profile: IQP1 through IQP8.
