decBusMaxDataFrameSize

Module: DEC-BUS-MIB

OID (symbolic): DEC-BUS-MIB::decBusMaxDataFrameSize

OID (numeric): 1.3.6.1.4.1.36.2.18.29.1.1.1.10

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The maximum AAL-5 SDU size for data frames sent over this emulated LAN. This must be one of the standard sizes defined in the LAN Emulation specification, in other words either 1516, 4544, 9234, or 18190 octets.

In an active emulated LAN, this parameter MUST have a consistent value in all of the LES and BUS components serving the emulated LAN. Otherwise, problems may result.

This columnar object's value may only be changed when 'decBus[Admin,Oper]Status' are 'down'.

What is decBusMaxDataFrameSize?

This OID sets the maximum AAL-5 SDU size for frames on this emulated LAN, one of the standard values 1516, 4544, 9234, or 18190 octets. Like decBusLanType, all components on the emulated LAN need the same setting, and it can only be changed while the BUS is administratively and operationally down.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.36.2.18.29.1.1.1.10
snmpwalk -v2c -c public <target> DEC-BUS-MIB::decBusMaxDataFrameSize

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.36.2.18.29.1.1.1.10.1
snmpget -v2c -c public <target> DEC-BUS-MIB::decBusMaxDataFrameSize.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.36.2.18.29.1.1.1.10.1 i <value>
