off     When set to off, the value 0 is inserted in bits 
        1:4 of G1 byte.

What is foreSonetPathDiagnosticsPREI?

A test-mode control for Path Remote Error Indication (formerly Path FEBE), encoded in bits 1-4 of the G1 byte: off always inserts 0 regardless of actual errors, on always inserts the maximum value (0x8), and auto (default) reports the real count. It's used to test a peer's handling of specific REI_P values.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.326.2.2.1.1.14.4.4.1.4
snmpwalk -v2c -c public <target> Fore-Sonet-Ext-MIB::foreSonetPathDiagnosticsPREI

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.326.2.2.1.1.14.4.4.1.4.1
snmpget -v2c -c public <target> Fore-Sonet-Ext-MIB::foreSonetPathDiagnosticsPREI.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.326.2.2.1.1.14.4.4.1.4.1 i <value>
