itrLinkDataBits

Module: MODULES-MIB

OID (symbolic): MODULES-MIB::itrLinkDataBits

OID (numeric): 1.3.6.1.4.1.81.21.3.2.1.15

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Number of data bits (7 or 8) in asynchronous mode. The value 'notSupported' is returned in synchronous mode.

What is itrLinkDataBits?

Sets the number of data bits (7 or 8) used in this link's asynchronous character framing, returning notSupported(255) when the link is in synchronous mode where this setting doesn't apply; an admin matches this to the attached DTE/modem's expected framing.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.81.21.3.2.1.15
snmpwalk -v2c -c public <target> MODULES-MIB::itrLinkDataBits

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.81.21.3.2.1.15.1
snmpget -v2c -c public <target> MODULES-MIB::itrLinkDataBits.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.81.21.3.2.1.15.1 i <value>
