The MIB module for Local Packet Transport Services(LPTS)
related information like the flows and the policer
values related to various flows present in the system.
The number of packets coming into the system is controlled
by the policer values associated with the protocol. Each
protocol is classified into different flows and a rate
limit is associated with the flows. Policer is a numerical
value controlling the number of packets entering the box.
The flows represent individual, specific protocols.
Flow types also represent the degree of trust for a given
packet. Ex: BGP packets coming from established session is
assigned one flow, packets from configured BGP peer are
assigned different flow . Other BGP packets are assigned
a third flow.
Definitions:
LPTS - Local Packet Transport Services.
It is a network infrastructure
subsystem that provides a common
facility for transport of packets
which are destined towards the router
(for-us packets), to the exact
applications. In addtion
to that, it also
provides policing of for-us packets
FlowType - Represents individual, specific protocols.
Flow also represents the degree of trust
for a given packet.
LC - Line Cards.
Policer - Index to FlowType.
CurrentRate - Number of packets allowed
into the box in PPS (Packets Per Second).
Type - Defines the scope of the flow applicable at
a specific node or Line card.
Precedence - Precedence is the selection mechanism for
a specific Type if more than one Type is
configured for the same flow. 'local'
FlowType has higher precedence over 'global'
and 'static' FlowTypes. 'global' FlowType has
higher precedence over 'static' FlowType.
nodeID - The line card for which the flow configuration
is made. |
