lpArcTotalConnectionPoolCapacity

Module: Nortel-Magellan-Passport-AtmBaseMIB

OID (symbolic): Nortel-Magellan-Passport-AtmBaseMIB::lpArcTotalConnectionPoolCapacity

OID (numeric): 1.3.6.1.4.1.562.2.4.1.12.19.100.1.5

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-write

Description: This attribute is migrated to the Lp/n Eng Arc Ov attribute of the same name.

This attribute specifies the maximum number of connections (both VCC and VPC) that can be enabled on the LogicalProcessor.

If the LogicalProcessor is associated with a card of a cardType other than one of the following: 3pE3Atm, 3pDS3Atm, 3pOC3MmAtm, 3pOC3SmAtm, 3pE1Atm, 3pDS1Atm, 2pJ6MAtm; the value of the attribute restricts the sum of the (maxVccs + maxVpcs) across all AtmIfs bound to this LogicalProcessor.

If the LogicalProcessor is associated with a card of one of the following cardTypes: 3pE3Atm, 3pDS3Atm, 3pOC3MmAtm, 3pOC3SmAtm, 3pE1Atm, 3pDS1Atm, 2pJ6MAtm; the number of available connections are distributed equally across the ports on the FP. The number of connections associated to a particular port will limit the size of the Vcc space defined by the ConnMap of the AtmIf linked to the port. Furthermore, the value of this attribute is restricted based on the number of ports on the card. For one port cards, the minimum is 512, the maximum is 4096 and the value must be divisible by 256. For two port cards, the minimum is 1024, the maximum is 8192 and the value must be divisible by 512. For three port cards, the minimum is 1536, the maximum is 7680 and the value must be divisible by 768.

Increasing the value of this attribute reduces the CQM memory available for cell and frame free list.

This attribute must be set to 0 if the connectionPoolCapacity attribute is set to non-zero values.

What is lpArcTotalConnectionPoolCapacity?

Sets the maximum combined number of ATM VCC and VPC connections (0-10752) this FP's LogicalProcessor may enable. Per its own DESCRIPTION the setting has been migrated to the lpEngArcOvTotalConnectionPoolCapacity attribute on newer FPs, so an admin tuning connection capacity on current hardware should use that attribute instead; on one-port cards the value must be between 512 and 4096 and divisible by 256.
