System Maintenance Commands 109
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.
Fragments/Undersize Received - The total number of packets received that
were less than 64 octets in length (excluding framing bits but including FCS
octets).
Alignment Errors - The total number of packets received that had a length
(excluding framing bits, but including FCS octets) of between 64 and 1518
octets, inclusive, but had a bad Frame Check Sequence (FCS) with a non-inte-
gral number of octets.
Rx FCS Errors - The total number of packets received that had a length
(excluding framing bits, but including FCS octets) of between 64 and 1518
octets, inclusive, but had a bad Frame Check Sequence (FCS) with an integral
number of octets
Overruns - The total number of frames discarded as this port was overloaded
with incoming packets, and could not keep up with the inflow.
Received Packets Not Forwarded
Total - A count of valid frames received which were discarded (in other
words, filtered) by the forwarding process.
Local Traffic Frames - The total number of frames dropped in the forward-
ing process because the destination address was located off of this port.
802.3x Pause Frames Received - A count of MAC Control frames received
on this interface with an opcode indicating the PAUSE operation. This counter
does not increment when the interface is operating in half-duplex mode.
Unacceptable Frame Type - The number of frames discarded from this port
due to being an unacceptable frame type.
VLAN Membership Mismatch - The number of frames discarded on this
port due to ingress filtering.
VLAN Viable Discards - The number of frames discarded on this port when
a lookup on a particular VLAN occurs while that entry in the VLAN table is
being modified, or if the VLAN has not been configured.
Multicast Tree Viable Discards - The number of frames discarded when a
lookup in the multicast tree for a VLAN occurs while that tree is being modi-
fied.
Reserved Address Discards - The number of frames discarded that are des-
tined to an IEEE 802.1 reserved address and are not supported by the system.
Broadcast Storm Recovery - The number of frames discarded that are des-
tined for FF:FF:FF:FF:FF:FF when Broadcast Storm Recovery is enabled.
CFI Discards - The number of frames discarded that have CFI bit set and the
addresses in RIF are in non-canonical format.
Upstream Threshold - The number of frames discarded due to lack of cell
descriptors available for that packet's priority level.
