phivRouteSegBuffSize

Module: DECnet-iv

OID (symbolic): DECnet-iv::phivRouteSegBuffSize

OID (numeric): 1.3.6.1.2.1.18.5.13

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This parameter value determines the maximum size of an end-to-end segment. The size is a decimal integer in the range 1-65535. This size is in bytes. This size includes protocol overhead down to and including the End Communication layer, plus a constant value of 6. (This value of 6 is included to provide compatibility with the BUFFER SIZE parameter definition.) It does not include Routing or Data link overhead (except for the constant value of 6).

What is phivRouteSegBuffSize?

Sets the maximum size, in bytes (1-65535), of an end-to-end segment that the End Communication layer can transmit or receive, including protocol overhead down to that layer plus a fixed 6-byte compatibility offset. Must stay less than or equal to phivRouteBuffSize, the Routing layer's own maximum forwarding size.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.18.5.13
snmpwalk -v2c -c public <target> DECnet-iv::phivRouteSegBuffSize

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.18.5.13.1
snmpget -v2c -c public <target> DECnet-iv::phivRouteSegBuffSize.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.2.1.18.5.13.1 i <value>
