Understanding How QoS Works
These sections describe how QoS works:
•
Overview of QoS
Typically, networks operate on a best-effort delivery basis, which means that all traffic has equal priority and an equal chance of being delivered in a timely manner. When congestion occurs, all traffic has an equal chance of being dropped.
QoS selects network traffic, prioritizes it according to its relative importance, and provides priority-indexed treatment through congestion-avoidance techniques. Implementing QoS in your network makes network performance more predictable and bandwidth utilization more effective.
QoS classifies traffic by assigning priority-indexed IEEE 802.1p class of service (CoS) values to frames at supported ingress ports. On the Catalyst 5000 family switches, for IPv4 traffic destined for a router, QoS can classify packets that match an access-control entry (ACE) by setting the IP precedence bits (in the IP header) and CoS value in the frame header.
QoS implements scheduling on supported egress ports with transmit queue drop thresholds and multiple transmit queues that use the IEEE 802.1p CoS values to give preference to higher-priority traffic. Figure 15-1 shows how QoS affects the traffic flow through a Catalyst 5000 family switch.

QoS Terminology
The following QoS terminology is used in this chapter:
•
–
–
•
•
•
•
•
Understanding Classification and Marking
These sections describe the three supported methods of classification and marking:
•
•
•
Understanding Classification and Marking at the Ingress Port
ISL or 802.1Q frames are not classified or marked at the ingress port; the existing CoS value is honored.
•
•
On the Catalyst 5000 family switches, QoS classifies and marks all other frame types that enter the switch through a supported ingress port with the configured CoS value of the port (the default is zero). On the Catalyst 4000 family, 2948G, and 2980G switches, QoS classifies and marks all other frame types that enter the switch with the default CoS value configured for the entire switch. You cannot mark traffic on a per-port basis.
Note
Understanding Classification and Marking Based on Destination
On the Catalyst 5000 family switches, QoS can rewrite the CoS value with a configurable value in frames destined for selected destination host Media Access Control (MAC) address and VLAN pairs (see the "Mapping a CoS Value to a Host Destination MAC Address and VLAN Pair" section). Destination-based marking overwrites any CoS value previously written, including port-based CoS values.
Understanding Classification and Marking Based on an ACE
On the Catalyst 5000 family switches, for IPv4 traffic destined for a router, QoS can perform classification of traffic that matches the parameters in an ACE under the following conditions:
•
•
–
–
Use the show mls entry qos command to display information about the Layer 3-switched traffic on which QoS has performed ACE-based classification. QoS might take up to 1 second to start ACE-based classification of Layer 3-switched traffic.
If ACE-based classification occurs, QoS sets the IP precedence bits in the IP header to match the CoS value. ACE-based marking overwrites any CoS value previously written, including port-based and destination-based CoS values.
These parameters can be specified in an ACE:
•
•
•
•
•
For information on configuring ACEs, see the "Creating an Access Control Entry" section.
Understanding Scheduling
On the Catalyst 5000 family switches, there is one non-user-configurable transmit queue and four user-configurable transmit queue drop thresholds for each port. Ports of this type are specified using the 1q4t keyword in QoS-related commands.
QoS uses the transmit queue drop thresholds to schedule transmission of network traffic from the switch through supported egress ports. By default, the four transmit queue drop thresholds function as follows:
•
•
•
•
Note
On the Catalyst 4000 family, 2948G, and 2980G switches, there are two user-configurable transmit queues and a single non-user-configurable transmit queue drop threshold for each port. Ports of this type are specified using the 2q1t keyword in QoS-related commands.
QoS uses the transmit queues to schedule transmission of network traffic from the switch through egress ports. By default, all traffic is assigned to queue 1 and threshold 1 when QoS is enabled. All traffic destined for a transmit queue, regardless of classification, is subject to tail drop when the queue is full (that is, frames at the end of the queue are dropped).
Caution
Note

Enabling QoS Globally
To enable QoS globally on the switch, perform this task in privileged mode:
This example shows how to enable QoS:
Console> (enable) set qos enableQoS is enabled.Console> (enable)Configuring the Default CoS Value for the Switch
On the Catalyst 4000 family, 2948G, and 2980G switches, QoS assigns unclassified frames received on any port on the switch that the CoS value configured for the switch. The default CoS value is zero.
Note
To set the default CoS value for a Catalyst 4000 family, 2948G, or 2980G switch, perform this task in privileged mode:
Step 1
Set the CoS value for the switch.
set qos defaultcos cos-value
Step 2
Verify the CoS value of the switch.
show qos info [runtime | config]
This example shows how to set CoS equal to 7 in all unclassified frames received on the switch and verify the configuration:
Console> (enable) set qos defaultcos 7qos defaultcos set to 7Console> (enable)Configuring the CoS Value for a Port
On the Catalyst 5000 family switches, QoS assigns to unclassified frames received through a supported port the CoS value configured for that port. The default CoS value is zero.
Note
To set the CoS value for a port, perform this task in privileged mode:
Step 1
Set the CoS value for a port.
set port qos mod_num/port_num cos cos-value
Step 2
Verify the CoS value of the port.
show port qos mod_num/port_num
This example shows how to set CoS equal to 7 in all unclassified frames received through port 8/1 and verify the configuration:
Console> (enable) set port qos 8/1 cos 7Port 8/1 qos cos set to 7Console> (enable) show port qos 8/1QoS is enabled on 8/1Port 8/1 has 1 transmit queue with 4 drop thresholds (1q4t).QoS setting in NVRAM:Default CoS = 7Run time setting of QoS:Default CoS = 7Console> (enable)Reverting to the Default Switch CoS Value
On the Catalyst 4000 family, 2948G, and 2980G switches, to revert to the default switch CoS value, perform this task in privileged mode:
Step 1
Revert to the default CoS value for the switch.
clear qos defaultcos
Step 2
Verify that the default CoS value was restored.
show qos info [runtime | config]
This example shows how to revert to the default CoS value for port 8/1 and verify the configuration:
Console> (enable) clear qos defaultcosqos defaultcos setting cleared.Console> (enable)Reverting to the Default Port CoS Value

Note
To assign a CoS value to all frames destined for a particular host destination MAC address and VLAN number pair, perform this task in privileged mode:
This example shows how to assign CoS 2 to a destination MAC address and VLAN number pair and verify the configuration:
Console> (enable) set qos mac-cos 00-40-0b-30-03-48 525 2CoS 2 is assigned to 00-40-0b-30-03-48 vlan 525.Console> (enable) show qos mac-cos 00-40-0b-30-03-48VLAN Dest MAC CoS---- ------------------ ---525 00-40-0b-30-03-48 2Console> (enable)Creating an Access Control Entry
Use the set qos ip-filter command to create access control entries (ACEs) with Layer 3 values or with both Layer 3 and 4 values.
Note
The dest_addr/netmask parameter is the destination IP address and netmask. The src_addr/netmask parameter is the source IP address and netmask. The cos (CoS) parameter range is 0-7. The address and netmask can specify a network, subnet, or host address.
Frames are compared to the access control entries sequentially. QoS uses the first match found. By default, ACEs are added to the end of the access control list. Use the optional before ACE# keyword and parameter to position an entry within the list (use the show qos ip command to display the access control list).
The dst_port parameter is the Layer 4 destination port number. The src_port parameter is the Layer 4 source port number. You can use zero as a wildcard for either or both port numbers.
To create an ACE, perform this task in privileged mode:
This example shows how to create ACEs, and an ACE within the list, and verify the configuration:

Note
To configure a router MAC address to use with QoS (except for MLS-RP), perform this task in privileged mode:
Step 1
Configure a router for use with QoS.
set qos router-mac MAC_addr vlan
Step 2
Verify the configuration.
show qos router-mac [MAC_addr | vlan]
This example shows how to configure a router address in VLAN 2:
Console> (enable) set qos router-mac 00-40-0b-30-03-48 2Router MAC/Vlan is set for QoS.Console> (enable) show qos router-mac 00-40-0b-30-03-48Number MAC address Vlan #---------------------------------1 00-40-0b-30-03-48 2Console> (enable)Removing a Router Address
To remove a router or all routers from the QoS configuration, perform this task in privileged mode:
Step 1
Remove a router or all routers from the QoS configuration.
clear qos router-mac MAC_addr vlan
clear qos router-mac all
Step 2
Verify the configuration.
show qos router-mac
This example shows how to clear a router address in VLAN 2:
Console> (enable) clear qos router-mac 00-40-0b-30-03-48 2QoS Router MAC/Vlan(s) cleared.Console> (enable)Configuring Transmit Queue Drop Thresholds
Use the set qos wred-threshold command to set the transmit queue drop thresholds.
Note
The port_type is hardware-dependent. Use the show port capabilities command to determine the port_type for your hardware. The port type is defined by the number of transmit queues and the number of drop thresholds supported on the port. For example, the 1q4t port type supports one transmit queue and four drop thresholds.
The q# is the transmit queue number. The thresholds are specified as percentages, ranging from 1 to 100. A value of 10 indicates a threshold when the buffer is 10 percent full. The number of threshold percentages you can specify depends on the port_type.
To configure the transmit queue drop thresholds on all ports in the switch, perform this task in privileged mode:
Set the transmit drop queue thresholds.
set qos wred-threshold port_type tx queue q# threshold_percentage_values
This example shows how to configure the transmit queue drop thresholds:
Console> (enable) set qos wred-threshold 1q4t tx queue 1 30 50 80 100Transmit drop thresholds for queue 1 set at 30% 50% 80% 100%Console> (enable)Mapping CoS Values to Transmit Queues and Drop Thresholds
Use the set qos map command to associate CoS values to transmit queue drop thresholds.
The port_type is hardware-dependent. Use the show port capabilities command to determine the port_type for your hardware. The port type is defined by the number of transmit queues and the number of drop thresholds supported on the port. For example, the 1q4t port type supports one transmit queue and four drop thresholds.
The q# is the transmit queue number. The threshold# is the drop threshold number for the specified queue.
The cos_list is the list of CoS values to map to the specified transmit queue and drop threshold. On the Catalyst 4000 family, 2948G, and 2980G switches, CoS values must be specified in pairs (0-1, 2-3, 4-5, and 6-7).
To associate CoS values to a transmit queue and drop threshold, perform this task in privileged mode:
Associate a CoS value to a transmit queue and drop threshold.
set qos map port_type q# threshold# cos cos_list
This example shows how to assign the CoS values 4 through 7 to the first transmit queue and the second drop threshold for that queue on a 1q4t port (Catalyst 5000 family switches):
Console> (enable) set qos map 1q4t 1 2 cos 4-7Qos tx priority queue and threshold mapped to cos successfully.Console> (enable)This example shows how to map CoS values 4 through 7 to the second transmit queue and the first drop threshold for that queue on a 2q1t port (Catalyst 4000 family and 2926G switches):
Console> (enable) set qos map 2q1t 2 1 cos 4-7Qos tx priority queue and threshold mapped to cos successfully.Console> (enable)Reverting to the Default CoS-to-Transmit Queue and Drop Threshold Mapping
Use the clear qos map command to revert to the default CoS-to-transmit queue and drop threshold mappings.
The port_type is hardware-dependent. Use the show port capabilities command to determine the port_type for your hardware.
To revert to the default CoS-to-transmit queue and drop threshold mappings, perform this task in privileged mode:
Revert to default CoS-to-transmit queue and drop threshold mappings.
clear qos map port_type
This example shows how to return the CoS-to-transmit queue and drop threshold mappings to the default values on 1q4t ports (Catalyst 5000 family switches):
Console> (enable) clear qos map 1q4tQos map setting cleared.Console> (enable)This example shows how to return the CoS-to-transmit queue and drop threshold mappings to the default values on 2q1t ports (Catalyst 4000 family, 2948G, and 2980G switches):

Note
Understanding QoS Policy
The term QoS policy refers to the QoS values, such as how packets are classified and scheduled as they pass through the switch.
A valid QoS router MAC address must be configured for COPS to activate. Only the packets destined for the configured router will be classified. For more information on configuring the router MAC address, see "Configuring the Router MAC Address" on page 13.
Selecting COPS as the QoS Policy Source
QoS uses locally configured QoS values as the default QoS policy source. To select COPS as the QoS policy source, perform this task in privileged mode:
Step 1
Select COPS as the QoS policy source.
set qos policy-source {local | cops}
Step 2
Verify the QoS policy source.
show qos policy-source
This example shows how to select COPS as the QoS policy source:
Console> (enable) set qos policy-source copsQoS policy source for the switch set to COPS.Console> (enable) show qos policy-sourceQoS policy source for the switch set to COPS.QoS runtime policy source for the switch is local.Console> (enable)When you select COPS as the QoS policy source, the following values switch from locally configured values to received COPS values:
•
•
•
Selecting Locally Configured QoS Policy
To select locally configured QoS policy, perform this task in privileged mode:
Step 1
Select locally configured QoS policy.
set qos policy-source {local | cops}
Step 2
Verify the QoS policy source.
show qos policy-source
This example shows how to select locally configured QoS policy:
Console> (enable) set qos policy-source localQoS policy source for the switch set to local.Console> (enable) show qos policy-sourceQoS policy source for the switch set to local.Console> (enable)Configuring Roles
COPS does not configure ports using slot number and port number parameters. COPS uses roles that you create and assign to the switch.
A role is a name that describes the capability of ports (for example, access or mod2_1-4). Only one role combination, with up to 64 roles, can be assigned per switch. You can assign more than one role name to a switch (for example, mod2ports1-12 and access), with the limitation that the combined length of role names cannot exceed 255 characters.
The role name can be up to 31 characters long, and is not case-sensitive, but may include uppercase and lowercase letters, consisting of a-z and A-Z, and numbers 0-9, the dash character (-), the underscore character (_), and the period character (.). Role names must start with an alphabetic character.
When you first assign a new role to a switch, the role is created.
To assign roles to a switch, perform this task in privileged mode:
Step 1
Assign roles to a port ASIC.
set cops roles role1 [role2] ...
Step 2
Verify the roles for the port.
show cops roles
This example shows how to assign two new roles to the switch:
Console> (enable) set cops roles backbone accessNew role `backbone' created.New role `access' created.Roles added successfully.Console> (enable)Deleting Roles
To delete a role (which removes it from all ports), perform this task in privileged mode:
Step 1
Delete a role.
clear cops {all-roles | roles role1 [role2] ...}
Step 2
Verify the roles for the port.
show cops roles
This example shows how to delete a role:
Console> (enable) clear cops roles backbone_port main_portRoles cleared.Console> (enable)Configuring Policy Decision Point Servers
Note
COPS obtains QoS policy from a PDP server. You need to configure a primary PDP server and, optionally, a backup PDP server to obtain QoS policy.
To configure a PDP server, perform this task in privileged mode:
Step 1
Configure a PDP server.
set cops server ip_address [port] [primary]
Step 2
Verify the PDP server configuration.
show cops info
The ip_address parameter can be the IP address or name of the server.
The port variable is the PDP server TCP port number.
The first ip_address address specified is set as the primary server. If an additional ip_address is set as a COPS server, it becomes the secondary server, unless specified as primary. The previously entered ip_address becomes the secondary server.
This example shows how to configure a PDP server:
Console> (enable) set cops server my_server1 primarymy_server1 added to the COPS diff-serv server table as primary server.my_server1 added to the COPS rsvp server table as primary server.Console> (enable)Deleting the PDP Server Configuration
To delete the PDP server configuration, perform this task in privileged mode:
Step 1
Delete the PDP server configuration.
clear cops server {all | ip_address}
Step 2
Verify the PDP server configuration.
show cops info
This example shows how to delete PDP server configuration:
Console> (enable) clear cops server allAll COPS diff-serv servers cleared.All COPS rsvp servers cleared.Console> (enable)Configuring the COPS Domain Name
PDP servers use a COPS domain name to communicate with policy enforcement point (PEP) devices such as switches. To configure a COPS domain name for the switch, perform this task in privileged mode:
Step 1
Configure the COPS domain name.
set cops domain-name domain_name
Step 2
Verify the COPS domain name.
show cops info
This example shows how to configure a COPS domain name:
Console> (enable) set cops domain-name my_domainDomain name set to my_domain.Console> (enable)Deleting the COPS Domain Name
To delete the COPS domain name, perform this task in privileged mode:
Step 1
Delete the COPS domain name.
clear cops domain-name
Step 2
Verify the configuration.
show cops info
This example shows how to delete the COPS domain name:
Console> (enable) clear cops domain-nameDomain name cleared.Console> (enable)Configuring the COPS Communications Parameters
To configure the parameters that COPS uses to communicate with the PDP server, perform this task in privileged mode:
Step 1
Configure the parameters that COPS uses to communicate with the PDP server.
set cops retry-interval initial increment maximum
Step 2
Verify the configuration.
