rEtherHistoryJabbers
Module: SWITCH-RMON-MIB
OID (symbolic): SWITCH-RMON-MIB::rEtherHistoryJabbers
OID (numeric): 1.3.6.1.4.1.8886.6.1.22.2.2.1.13
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: The number of packets received during this sampling interval that were longer than 1518 octets (excluding framing bits but including FCS octets), and had either a bad Frame Check Sequence (FCS) with an integral number of octets (FCS Error) or a bad FCS with a non-integral number of octets (Alignment Error).
Note that this definition of jabber is different than the definition in IEEE-802.3 section 8.2.1.5 (10BASE5) and section 10.3.1.4 (10BASE2). These documents define jabber as the condition where any packet exceeds 20 ms. The allowed range to detect jabber is between 20 ms and 150 ms.
What is rEtherHistoryJabbers?
This counter records oversized (>1518 octet), bad-FCS packets that occurred during this specific sampling interval. A bucket showing a sudden jabber spike helps pinpoint when a malfunctioning NIC started misbehaving.
