Figure 49 A QoS policy for voice over IP and data traffic

Configuring a QoS policy for layer 4 TCP/UDP traffic (Example)

The following example shows how to configure a rate limiting policy for TCP/UDP application

streams and apply the policy on all inbound switch ports.

HP Switch(config)#: class ipv4 http

HP Switch(config-class)#: match tcp any any eq 80

HP Switch(config-class)#: match tcp any any eq 443

HP Switch(config-class)#: match tcp any any eq 8080

HP Switch(config-class)#: exit

HP Switch(config)#: class ipv4 kazaa

HP Switch(config-class)#: match tcp any eq 1214 any

HP Switch(config-class)#: match tcp any any eq 1214

HP Switch(config-class)#: exit

HP Switch(config)#: class ipv4 gnutella

HP Switch(config-class)#: match tcp any range 6346 6347 any

HP Switch(config-class)#: match tcp any any range 6346 6347

HP Switch(config-class)#: match udp any range 6346 6347 any

HP Switch(config-class)#: match udp any any range 6346 6347

HP Switch(config-class)#: exit

HP Switch(config)#: policy qos PrioritizeSuspectTraffic

HP Switch(config-policy)#: class ipv4 http action rate-limit kbps 7000

HP Switch(config-policy)#: class ipv4 kazaa action rate-limit kbps 3500

HP Switch(config-policy)#: class ipv4 gnutella action rate-limit kbps 3500

HP Switch(config-policy)#: exit

HP Switch(config)#: interface all service-policy PrioritizeSuspectTraffic in

Configuring a QoS policy for subnet traffic (Example)

The next example shows how to configure a QoS policy that prioritizes inbound traffic sent to and

received from a specified subnet (15.29.16.0/10) and TCP port range on VLAN 5.

Figure 50 A QoS policy for IPv4 and IPv6 subnet traffic on a VLAN interface

Using Differentiated Services Codepoint (DSCP) mapping

The DSCP Policy Table associates an 802.1p priority with a DSCP codepoint in an IPv4/IPv6

packet. Using DSCP codepoints in your network allows you to set a LAN policy that operates

independently of 802.1Q VLAN-tagging.
