ppeLrgUxRxCnt

Module: CTATX-MIB

OID (symbolic): CTATX-MIB::ppeLrgUxRxCnt

OID (numeric): 1.3.6.1.4.1.97.3.3.3.1

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The number of large data buffers to allocate for the PPE to create packets. This value may be changed automatically by the ES/1 as a result of enabling IPX routing. The ES/1 will calculate the minimum number of such buffers that are needed for the number of configured ports and may adjust this count upward if needed.

What is ppeLrgUxRxCnt?

This read-write INTEGER sets the number of large receive data buffers allocated for the Packet Processing Engine, and the ES/1 may adjust it automatically when IPX routing is enabled based on the number of configured ports. An administrator monitors it because undersized large-buffer allocation can cause dropped high-MTU traffic under load. For example, after enabling IPX routing, the admin notices ppeLrgUxRxCnt increased automatically as the ES/1 recalculated the buffers needed for the newly active ports.
