ifwanCoding

Module: CLEARTRAC7-MIB

OID (symbolic): CLEARTRAC7-MIB::ifwanCoding

OID (numeric): 1.3.6.1.4.1.727.7.2.2.2.1.8

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: For SDLC and HDLC protocols only. Bit coding for CRC purposes. For NORMAL and NRZI coding the computed CRC is preset at 1. For normal coding with CRC0 (CRC0-NML) and NRZI coding with CRC0 (CRC0-NZI) the computed CRC is preset at 0. The values NRZ-CRC0 and NRZI-CRC0 are available for the HDLC protocol only.

What is ifwanCoding?

This read-write enumeration, applicable to SDLC and HDLC protocols only, selects the bit coding scheme, such as nrz, nrzi, or their CRC-preset variants, used for CRC purposes on the port. An administrator sets this to match what the connected far-end device expects, since normal and NRZI coding preset the computed CRC differently than the CRC0 variants. For example, mismatching this coding setting between two connected units running HDLC could cause the link to report persistent CRC errors even though the physical connection is otherwise fine.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.727.7.2.2.2.1.8
snmpwalk -v2c -c public <target> CLEARTRAC7-MIB::ifwanCoding

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.727.7.2.2.2.1.8.1
snmpget -v2c -c public <target> CLEARTRAC7-MIB::ifwanCoding.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.727.7.2.2.2.1.8.1 i <value>
