This OID counts how many inbound jabber packets, oversized frames that also fail the CRC check, have been received on this 40 Gbps Ethernet (40GbE) interface. Jabbers point to a transmitting device that is malfunctioning at the hardware level, continuing to send corrupted, oversized frames, so this counter is one of the more serious NIC-fault indicators an admin can watch for on this link. For example, discovering a growing jabber count on a 40GbE trunk aggregating several client services traced back to a single connected appliance would justify replacing that device's network interface rather than looking at the transport link itself.
