sfddiSMTBufferSize

Module: CTATX-MIB

OID (symbolic): CTATX-MIB::sfddiSMTBufferSize

OID (numeric): 1.3.6.1.4.1.97.3.8.1.1.25

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The amount of packet buffer space to reserve for processing SMT frames. Possible values 9000 - 18000. (FIOM MIB only)

What is sfddiSMTBufferSize?

This read-write INTEGER, restricted to the FIOM MIB variant and valid from 9000 to 18000, sets how much packet buffer space is reserved for processing FDDI SMT (Station Management) frames. An admin increases this on a busy FDDI ring generating heavy SMT traffic (frequent neighbor notifications, status reports) to avoid SMT frame loss due to buffer exhaustion. Raising sfddiSMTBufferSize toward 18000 would help a ring experiencing frequent topology changes that generate bursts of SMT control traffic.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.97.3.8.1.1.25
snmpwalk -v2c -c public <target> CTATX-MIB::sfddiSMTBufferSize

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.97.3.8.1.1.25.1
snmpget -v2c -c public <target> CTATX-MIB::sfddiSMTBufferSize.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.97.3.8.1.1.25.1 i <value>
