Rate Limiting - HP MSM317 Installation And Configuration Manual

DiffServ (Differentiated Services)
This mechanism classifies traffic based on the value of the Differentiated Services (DS) codepoint
field in IPv4 and IPv6 packet headers (as defined in RFC2474). The codepoint is composed of the
six most significant bits of the DS field.

Queue defined by the Default traffic priority setting or the LLDP Network
Policy TLV if defined. (See LLDP Network Policy TLV QoS setting for details.
802.1p + DiffServ
When this option is selected, both methods are used with 802.1p taking priority.
802.1p
This mechanism classifies traffic based on the value of the VLAN priority field present within the
VLAN header.

Rate limiting

This option lets you control the speed at which traffic can be sent/received on the port.
Ingress rate
Set the maximum rate at which this port will accept ingress traffic. Traffic in excess of the set rate
is dropped. When using this option you should enable Flow control. This will ensure that a client
device does not send traffic in excess of the ingress limit. (Providing that the client device supports
flow control.)
Traffic
Select the type of traffic to which rate limiting applies: Broadcast, Broadcast and multicast, or All
(broadcast, multicast, and unicast).
