Quality of Service (QoS)
DiffServ Examples
For information on the access list and access mask commands in the following examples, see
Chapter 10, “Access Policies”.
Use the following command to use the DiffServe code point value to assign traffic to the hardware
queues:
enable diffserv examination ports all
In the following example, all the traffic from network 10.1.2.x is assigned the DiffServe code point 23
and the 802.1p value of 2:
create access-mask SriIpMask source-ip/24
create access-list TenOneTwo access-mask SrcIpMask source-ip 10.1.2.0/24 permit qp3
set code-point 23 set dot1p 2
Physical and Logical Groupings
Two traffic groupings exist in this category:
• Source port
• VLAN
Source port
A source port traffic grouping implies that any traffic sourced from this physical port uses the indicated
QoS profile when the traffic is transmitted out to any other port. To configure a source port traffic
grouping, use the following command:
config ports <portlist> qosprofile <qosprofile>
In the following modular switch example, all traffic sourced from port 7 uses the QoS profile named qp3
when being transmitted.
config ports 7 qosprofile qp3
VLAN
A VLAN traffic grouping indicates that all intra-VLAN switched traffic and all routed traffic sourced
from the named VLAN uses the indicated QoS profile. To configure a VLAN traffic grouping, use the
following command:
config vlan <name> qosprofile <qosprofile>
For example, all devices on VLAN servnet require use of the QoS profile qp4. The command to configure
this example is as follows:
config vlan servnet qosprofile qp4
Verifying Physical and Logical Groupings
To verify settings on ports or VLANs, use the following command:
show qosprofile <qosprofile>
