QoS Configuration Notes:
The following table is a sample 8 queue DiffServ architecture which can be implemented on a 14.20 BayRS router. The BCC commands that follow implement Table 1. The queues are only a sample configuration to explain how to configure DS-QMS.

QoS Configuration of Table 1
The first step is to place the diffserv protocol on all interfaces on the router that are to participate in the diffserv process. The ethernet interface is typically where the DSCP marking is done and the serial interface is typically where the dequeing process is done. DSQMS only works on serial interfaces.
box# ip
ip# diffserv
diffserv#ethernet/2/2
ethernet/2/2# ip 192.168.1.1/24
ip/192.168.1.1/255.255.255.0#diffserv
diffserv/192.168.1.1#box
If the interface is a serial interface you have an additional step:
box# ip
ip# diffserv
diffserv#serial/2/2
serial/2/2# ppp (Or whatever layer 2 encapsulaton type you're using such as standard, SDLC, frame-relay, etc.)
ppp#ip 192.168.1.1/24
ip/192.168.1.1/255.255.255.0#diffserv
diffserv/192.168.1.1# box
If the inbound traffic filters for DSCP marking are to be done manually via Site Manager or BCC then you can skip to the RED configuration. If you're going to use OPS via COPS to create the filters, then perform the following steps.
box# cops address 192.168.1.1 id router1
The IP address is the differentiated services enabled router interface to which route filters are to be applied. The name 'router1' just places a name associated with this router.
Cops# cops-server 192.168.1.100
Cops-server/192.168.1.100#back
Cops#box; serial/1/1;ppp;ip 192.168.1.1/24;
ip/192.168.1.1/255.255.255.0#diffserve config-type cops
(Check that the config-type must be static if not set to COPS.)
diffserve/192.168.1.1#box
All of the following commands must be done in BCC. The previously mentioned commands as well as the DSCP marking filters can all be done via Site Manager.
box#red
This step enables RED for the entire router.
red#dsqms-red id 1
dsqms-red/1# min-threshold 50
dsqms-red/1# max-threshold 90;
dsqms-red/1# dsqms-red 2
dsqms-red/2# min-threshold 50
dsqms-red/2# max-threshold 90
dsqms-red/2# first-order-const 2
dsqms-red/2# second-order-const 20
dsqms-red/2# dsqms-red 3
dsqms-red/3# min-threshold 50
dsqms-red/3# max-threshold 90
dsqms-red/3# first-order-const 3
dsqms-red/3# second-order-const 30
dsqms-red/3# dsqms-red 4
dsqms-red/4# min-threshold 50
dsqms-red/4# max-threshold 90
dsqms-red/4# first-order-const 4
dsqms-red/4# second-order-const 40
dsqms-red/4# box
The above commands create 4 instances of RED. Each RED instance will be assigned to a particular DSCP within a queue. WRED is performed on different flows within the same queue. The min-threshold value indicates the queue size below which no packets are dropped by RED. The default value is 20. The max-threshold value indicates the queue size above which all packets are dropped by RED. The default value is 80. The first-order-const parameter specifies the first order constant used when calculating drop propability based on the average queue fraction, the queue size, and the min-threshold value. The default value is 1. The second-order-const parameter specifies the second order constant used when calculating drop probability based on the average queue fraction, the queue size, and the min-threshold value. The default value is 10. You don't have to configure these red id's if you're not going to use WRED as a congestion method. If you're going to use WRED, you can leave the thresholds and the constants at their default values. The changes listed above just give you a guideline as to how to change them if they need to be changed. The values presented are just my recommendations.
DSQMS must be enabled on a per interface basis with the appropriate queues created.

dsqms-queue/2/serial/2/2#flow-fairness enabled
(This parameter indicates whether a hash table is used to separate data packets into buckets within this queue. This mechanism improves fairness within a queue. The default is disabled.)
dsqms-queue/2/serial/2/2#jitter-const large
(Categorizes how sensitive traffic in this queue is to the jitter effect and thus provides an indicator for calculating the bucket size in flow fairness. Reset this parameter if the packets that this queue will handle are small (for example, VoIP packets) or large (for example, video packets) The default is normal).

The weights are then calculated by the ratio of a single queue's weight value to the sum of the weight values for all weighted queues.)

dsqms/serial/2/2# debug-level trace or debug-level detailed
(By default the router does not log messages generated by DSQMS. You must tell it do so. Enter debug-level non to disable the logging.)
dsqms/serial/2/2#restart set
(If you change parameters for the dsqms, dsqms-queue, or dsqms-classifier objects, you must restart DSQMS on the interface for the changes to take effect.)
dsqms/serial/2/2#
As a side note, when using BCC you can preference any TI only command by tic so that it can be executed without leaving TI. For instance, show ip int displays the status of the IP interfaces from within BCC. You can also issue the following command from the bcc prompt: bcc> tic show ip cir. The status of the IP interfaces will be displayed.

QoS Configuration of Table 1
The first step is to place the diffserv protocol on all interfaces on the router that are to participate in the diffserv process. The ethernet interface is typically where the DSCP marking is done and the serial interface is typically where the dequeing process is done. DSQMS only works on serial interfaces.
box# ip
ip# diffserv
diffserv#ethernet/2/2
ethernet/2/2# ip 192.168.1.1/24
ip/192.168.1.1/255.255.255.0#diffserv
diffserv/192.168.1.1#box
If the interface is a serial interface you have an additional step:
box# ip
ip# diffserv
diffserv#serial/2/2
serial/2/2# ppp (Or whatever layer 2 encapsulaton type you're using such as standard, SDLC, frame-relay, etc.)
ppp#ip 192.168.1.1/24
ip/192.168.1.1/255.255.255.0#diffserv
diffserv/192.168.1.1# box
If the inbound traffic filters for DSCP marking are to be done manually via Site Manager or BCC then you can skip to the RED configuration. If you're going to use OPS via COPS to create the filters, then perform the following steps.
box# cops address 192.168.1.1 id router1
The IP address is the differentiated services enabled router interface to which route filters are to be applied. The name 'router1' just places a name associated with this router.
Cops# cops-server 192.168.1.100
Cops-server/192.168.1.100#back
Cops#box; serial/1/1;ppp;ip 192.168.1.1/24;
ip/192.168.1.1/255.255.255.0#diffserve config-type cops
(Check that the config-type must be static if not set to COPS.)
diffserve/192.168.1.1#box
All of the following commands must be done in BCC. The previously mentioned commands as well as the DSCP marking filters can all be done via Site Manager.
box#red
This step enables RED for the entire router.
red#dsqms-red id 1
dsqms-red/1# min-threshold 50
dsqms-red/1# max-threshold 90;
dsqms-red/1# dsqms-red 2
dsqms-red/2# min-threshold 50
dsqms-red/2# max-threshold 90

dsqms-red/4# max-threshold 90
dsqms-red/4# first-order-const 4
dsqms-red/4# second-order-const 40
dsqms-red/4# box
The above commands create 4 instances of RED. Each RED instance will be assigned to a particular DSCP within a queue. WRED is performed on different flows within the same queue. The min-threshold value indicates the queue size below which no packets are dropped by RED. The default value is 20. The max-threshold value indicates the queue size above which all packets are dropped by RED. The default value is 80. The first-order-const parameter specifies the first order constant used when calculating drop propability based on the average queue fraction, the queue size, and the min-threshold value. The default value is 1. The second-order-const parameter specifies the second order constant used when calculating drop probability based on the average queue fraction, the queue size, and the min-threshold value. The default value is 10. You don't have to configure these red id's if you're not going to use WRED as a congestion method. If you're going to use WRED, you can leave the thresholds and the constants at their default values. The changes listed above just give you a guideline as to how to change them if they need to be changed. The values presented are just my recommendations.
DSQMS must be enabled on a per interface basis with the appropriate queues created.

(If you configure both weighted and priority queues on an interface, you may experience latency problems with the high-priority queues. To reduce delay for queues that need a constant delay rate when limited bandwidth is available, enable this parameter.)
dsqms/serial/2/2# debug-level trace or debug-level detailed
(By default the router does not log messages generated by DSQMS. You must tell it do so. Enter debug-level non to disable the logging.)
dsqms/serial/2/2#restart set
(If you change parameters for the dsqms, dsqms-queue, or dsqms-classifier objects, you must restart DSQMS on the interface for the changes to take effect.)

As a side note, when using BCC you can preference any TI only command by tic so that it can be executed without leaving TI. For instance, show ip int displays the status of the IP interfaces from within BCC. You can also issue the following command from the bcc prompt: bcc> tic show ip cir. The status of the IP interfaces will be displayed.
