What is foreSonetPathDiagnosticsC2Value?

Selects which C2 byte value is transmitted when foreSonetPathDiagnosticsC2 is set to on, covering payload types such as unequipped, ATM mapping, DS3 mapping, various VT-structured mappings, and an explicit payload-defect code. It lets an admin force a specific signal label onto the wire to test how the far end reacts.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.326.2.2.1.1.14.4.4.1.2
snmpwalk -v2c -c public <target> Fore-Sonet-Ext-MIB::foreSonetPathDiagnosticsC2Value

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.326.2.2.1.1.14.4.4.1.2.1
snmpget -v2c -c public <target> Fore-Sonet-Ext-MIB::foreSonetPathDiagnosticsC2Value.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.326.2.2.1.1.14.4.4.1.2.1 i <value>
