Description: Configured ATM DS3 C-bit Parity.

What is pportCbitParity?

This enables or disables C-bit parity framing on this ATM DS3 port. C-bit parity is the DS3 framing mode that carries far-end alarm and performance information in the overhead C-bits, so disabling it on this port when the carrier circuit expects it will blind you to FEAC-based far-end status like the one reported by pportdsx3FEACStatus. A DS3 circuit ordered from the carrier as C-bit parity would need this object set to enabled on this port to match, or performance monitoring on that link will be unreliable.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.4.2.1.33
snmpwalk -v2c -c public <target> CASCADE-MIB::pportCbitParity

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.4.2.1.33.1
snmpget -v2c -c public <target> CASCADE-MIB::pportCbitParity.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.277.1.4.2.1.33.1 i <value>
