circuitFwdTDParam2

Module: CIRCUIT-MIB

OID (symbolic): CIRCUIT-MIB::circuitFwdTDParam2

OID (numeric): 1.3.6.1.4.1.5812.6.8.1.25

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-write

Description: Parameter 2 of the forward traffic descriptor of type circuitFwdTdType. For type Ethernet, this value corresponds to Bc. For type Frame Relay, this value corresponds to Bc.

What is circuitFwdTDParam2?

This is the second forward-direction traffic parameter, representing the Committed Burst size (Bc) for Ethernet or Frame Relay circuits -- the amount of data that can be sent in a single burst at line rate while still being treated as within contract. Together with circuitFwdTDParam1's CIR, this shapes how bursty forward traffic on this circuit is allowed to be without being discarded or tagged as non-conforming (see circuitInFramesDiscard/circuitInFramesTagged). For example, setting this Bc value higher allows this circuit to tolerate larger momentary traffic spikes above its average CIR before those frames start getting flagged as excess.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5812.6.8.1.25
snmpwalk -v2c -c public <target> CIRCUIT-MIB::circuitFwdTDParam2

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.5812.6.8.1.25.1
snmpget -v2c -c public <target> CIRCUIT-MIB::circuitFwdTDParam2.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.5812.6.8.1.25.1 i <value>
