phivAdjBlockSize

Module: DECnet-iv

OID (symbolic): DECnet-iv::phivAdjBlockSize

OID (numeric): 1.3.6.1.2.1.18.11.1.1.3

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: This read-only parameter is the block size that was negotiated with the adjacent Routing layer during Routing initialization over a particular circuit. It includes the routing header, but excludes the data link header. This parameter is qualified by ADJACENT NODE.

What is phivAdjBlockSize?

The maximum message block size negotiated with the adjacent Routing layer during initialization on this circuit, including the routing header but excluding the data-link header. A mismatch between two nodes' negotiated block sizes can cause fragmentation or connectivity issues worth checking here.

Examples
