mlpppNbLargeBufs

Module: CXMLPPP-MIB

OID (symbolic): CXMLPPP-MIB::mlpppNbLargeBufs

OID (numeric): 1.3.6.1.4.1.495.2.1.6.49.3

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Determines the number of large size buffers for the MLPPP stack.

Range of Values: The maximum value of this object depends on the amount of RAM available on the system.

Default Value: 1

WARNING: When PPP ports are used, this value must be greater than 25 because the PPP module cannot use global buffers that were defined with OsParam.

You must decrease the OsParam small buffer parameter (cxOsNbSmallBufs) when you increase this value or you may run out of memory, and the system may crash.

Configuration Changed: administrative

What is mlpppNbLargeBufs?

This OID sets how many large-size buffers are created for the Multilink PPP stack, defaulting to 1. If PPP ports are in use, this must exceed 25 (since the PPP module can't share buffers set aside by OsParam), and the MIB warns to correspondingly lower the OsParam small buffer count to avoid running out of memory.
