mscTrkUnAckedFramerDataInversion

Module: Nortel-MsCarrier-MscPassport-UnackTrunksMIB

OID (symbolic): Nortel-MsCarrier-MscPassport-UnackTrunksMIB::mscTrkUnAckedFramerDataInversion

OID (numeric): 1.3.6.1.4.1.562.36.2.1.60.2.2.11.1.2

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This attribute determines whether data bits are to be inverted (1 to 0 and 0 to 1) before transmission of frames to the interface. If the value of this attribute is On, the incoming data bits will also be inverted when frames are received from the link before being processed.

This option is typically used in hdlc framing mode when inversion is used to guarantee 1's density.

Note that aborts (in hdlc and interrupting modes) are corrupted when data is inverted.

What is mscTrkUnAckedFramerDataInversion?

Enables or disables inverting data bits before transmission and after reception on this link; an admin turns it on in HDLC mode when bit inversion is needed to guarantee sufficient 1's density for clock recovery, but note it corrupts abort sequences when enabled.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.562.36.2.1.60.2.2.11.1.2
snmpwalk -v2c -c public <target> Nortel-MsCarrier-MscPassport-UnackTrunksMIB::mscTrkUnAckedFramerDataInversion

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.562.36.2.1.60.2.2.11.1.2.1
snmpget -v2c -c public <target> Nortel-MsCarrier-MscPassport-UnackTrunksMIB::mscTrkUnAckedFramerDataInversion.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.562.36.2.1.60.2.2.11.1.2.1 i <value>
