sonetMediumLineCoding

Module: SONET-MIB

OID (symbolic): SONET-MIB::sonetMediumLineCoding

OID (numeric): 1.3.6.1.2.1.10.39.1.1.1.1.4

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This variable describes the line coding for this interface. The B3ZS and CMI are used for electrical SONET/SDH signals (STS-1 and STS-3). The Non-Return to Zero (NRZ) and the Return to Zero are used for optical SONET/SDH signals.

What is sonetMediumLineCoding?

Identifies the line coding scheme used on this SONET/SDH interface: B3ZS or CMI for electrical (STS-1/STS-3) signals, NRZ or RZ for optical signals. An admin sets this to match the physical transceiver or electrical interface installed, since a mismatch here would misrepresent how the signal is actually encoded on the wire.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.10.39.1.1.1.1.4
snmpwalk -v2c -c public <target> SONET-MIB::sonetMediumLineCoding

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.10.39.1.1.1.1.4.1
snmpget -v2c -c public <target> SONET-MIB::sonetMediumLineCoding.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.2.1.10.39.1.1.1.1.4.1 i <value>

Start monitoring vendor-neutral, standards-based MIB, SONET/SDH transport equipment and optical interface line cards (section/line/path performance/fault status) with a free 30-day trial of IPNetwork Monitor. Create custom SNMP monitor using the SONET-MIB::sonetMediumLineCoding OID value, configure state conditions and alerts, and monitor any vendor-neutral, standards-based MIB, SONET/SDH transport equipment and optical interface line cards (section/line/path performance/fault status) from a single console.
