lpArcCdvAttenuation
Module: Nortel-Magellan-Passport-AtmBaseMIB
OID (symbolic): Nortel-Magellan-Passport-AtmBaseMIB::lpArcCdvAttenuation
OID (numeric): 1.3.6.1.4.1.562.2.4.1.12.19.100.1.41
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This attribute is migrated to the Lp/n Eng Arc Cqc Ov attribute cdvReduction.
This attribute enables the attenuation of the maximum Cell Delay Variation (CDV) of shaped transmit traffic.
When the value of this attribute is set to off, the CDV value can be determined by the following equation: CDV <= 2/ASR + 1/LS where ASR is the Actual Shaping Rate of the connection and LS is the Link Speed of the interface.
When the value of this attribute is set to on, the CDV relationship changes to the following equation: CDV <= 1/ASR + 1/LS
As can be noted from the equations above, setting this attribute to on can reduce the CDV significantly. CDV attenuation may be used to conform to policers which have strict Cell Delay Variance Tolerance (CDVT). However using this function reduces the transmit bandwidth utilization of the following cards: 3pDS3Atm, 3pOC3Atm.
What is lpArcCdvAttenuation?
Toggles a stricter Cell Delay Variation (CDV) bound for shaped transmit traffic: off keeps CDV <= 2/ASR + 1/LS, while on tightens it to CDV <= 1/ASR + 1/LS. An admin turns it on to satisfy a downstream policer with strict CDV-tolerance requirements, accepting a reduction in transmit bandwidth utilization on 3pDS3Atm and 3pOC3Atm cards as the tradeoff.
