Cisco – HP Procurve to Cisco – QOS

ciscohp-procurveqosvoip

I have a HP Procurve with the following:

vlan 4 
  name "Phones" 
  untagged 20 
  ip address 10.50.60.1 255.255.252.0 
  qos dscp 101110 

qos device-priority 10.50.100.10 dscp 101110 
qos device-priority 10.50.20.38 dscp 100010 
qos type-of-service diff-services

What is the Cisco equivalent command to accomplish the same?

Thanks

Assuming port GigabitEthernet1/20 in the Cisco switch...

You need to define the vlan interface on the Cisco...

interface Vlan4
 description Phones
 ip address 10.50.60.1 255.255.252.0

Then assign a switch port to the vlan...

interface GigabitEthernet1/20
 switchport access vlan 4
 switchport mode access
 auto qos voip trust 
 spanning-tree portfast
 spanning-tree bpduguard enable

As far as defining maps for your QoS policy, it may be dependent on the model of your Cisco switch.
You'll want dscp mode 46 for IP 10.50.100.10 (ef) and dscp mode 34 for IP 10.50.20.38 (af41).

My setups look like:

policy-map AutoQos-VoIP-Output-Policy
 class AutoQos-VoIP-Bearer-QosGroup
   set dscp ef
   set cos 5
    priority
    police cir percent 33

and on the port level...

 service-policy input AutoQos-VoIP-Input-Cos-Policy
 service-policy output AutoQos-VoIP-Output-Policy

What type of switch are you using?

Cisco – Setup Cisco RVS4000 QOS for VOIP

At a guess, your problem isn't LAN-side but on the cable modem. If you have 10 Mbps down and 2 Mbps up, you have slightly more outbound bandwidth than with the T1 link, but you are likely having more jitter and generating more outbound traffic. I'd suggest putting QoS on the cable router (or the link to the cable router), guaranteeing a portion of the bandwidth for VoIP.

Depending on packetization interval and protocol used, you're looking at roughly 30 kbps to 90 kbps per simultaneous call.

Rate Limiting with HP ProCurve 5406 QOS

The 5400zl series supports a very full feature list to provide quality of service (QoS) and traffic management. And for your specific requirement it also supports rate-limiting. Your best bet will be to upgrade to the latest version (K.15.8 at this point in time). The reference is the Advanced Traffic Management guide (current version)

What you need to do is 1. Define a class to match the traffic you wish to limit 2. Define a policy on how to treat the traffic 3. Apply the policy on a interface or VLAN

Something like the following should work:-

class ipv4 servers-to-be-slowed
    match ip 1.2.3.4/32 any
    match ip 1.2.3.5/32 any
    exit
policy qos SlowBadServers
    class servers-to-be-slowed action rate-limit kbps 1000
    exit
interface all service-policy SlowBadServers in

I have written interface all above but you probably want to apply it only to your so called head end connection
