foreSonetPathDiagnosticsPERDI

Module: Fore-Sonet-Ext-MIB

OID (symbolic): Fore-Sonet-Ext-MIB::foreSonetPathDiagnosticsPERDI

OID (numeric): 1.3.6.1.4.1.326.2.2.1.1.14.4.4.1.6

Description: Controls the insertion of Enhanced Remote Defect
 Indication. Bits 5,6, and 7 of G1 byte is used for the
 inserting ERDI.

on      When set to on, foreSonetPathDiagnosticsERDIValue
        is inserted in the bits 5,6,7 of G1 byte.
auto    When set to auto, resume normal operation using
        single bit RDI.

What is foreSonetPathDiagnosticsPERDI?

A test-mode control for Enhanced Remote Defect Indication, encoded in bits 5-7 of the G1 byte: on forces the value in foreSonetPathDiagnosticsERDIValue to be inserted, and auto (default) resumes normal single-bit RDI operation. It's used to simulate specific ERDI conditions when testing a peer's path-defect handling.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.326.2.2.1.1.14.4.4.1.6
snmpwalk -v2c -c public <target> Fore-Sonet-Ext-MIB::foreSonetPathDiagnosticsPERDI

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.326.2.2.1.1.14.4.4.1.6.1
snmpget -v2c -c public <target> Fore-Sonet-Ext-MIB::foreSonetPathDiagnosticsPERDI.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.326.2.2.1.1.14.4.4.1.6.1 i <value>
