17.2.4 Ether Ports PM Window
17.2.4.2 Ether Ports Utilization Window
The Utilization window shows the percentage of transmit (Tx) and receive (Rx) line bandwidth used by
the Ethernet ports during consecutive time segments. The Mode field displays the real-time mode status,
such as 100 Full, which is the mode setting configured on the E-Series port. However, if the E-Series
port is set to autonegotiate the mode (Auto), this field shows the result of the link negotiation between
the E-Series and the peer Ethernet device attached directly to the E-Series port.
The Utilization window provides an Interval drop-down list that enables you to set time intervals of
1 minute, 15 minutes, 1 hour, and 1 day. Line utilization is calculated with the following formulas:
Rx = (inOctets + inPkts * 20) * 8 / 100% interval * maxBaseRate
Tx = (outOctets + outPkts * 20) * 8 / 100% interval * maxBaseRate
etherStatsPkts128to255O
ctets
The total number of packets (including bad packets) received that were
between 128 and 255 octets in length inclusive (excluding framing bits but
including FCS octets).
etherStatsPkts256to511O
ctets
The total number of packets (including bad packets) received that were
between 256 and 511 octets in length inclusive (excluding framing bits but
including FCS octets).
etherStatsPkts512to1023
Octets
The total number of packets (including bad packets) received that were
between 512 and 1023 octets in length inclusive (excluding framing bits
but including FCS octets).
etherStatsPkts1024to1518
Octets
The total number of packets (including bad packets) received that were
between 1024 and 1518 octets in length inclusive (excluding framing bits
but including FCS octets).
etherStatsBroadcastPkts The total number of good packets received that were directed to the
broadcast address. Note that this does not include multicast packets.
etherStatsMulticastPkts The total number of good packets received that were directed to a multicast
address. Note that this number does not include packets directed to the
broadcast address.
etherStatsOversizePkts The total number of packets received that were longer than 1518 octets
(excluding framing bits, but including FCS octets) and were otherwise
well formed. Note that for tagged interfaces, this number becomes 1522
bytes.
etherStatsJabbers The total number of packets received that were longer than 1518 octets
(excluding framing bits, but including FCS octets), and had either a bad
FCS with an integral number of octets (FCS Error) or a bad FCS with a
nonintegral number of octets (Alignment Error).
etherStatsOctets The total number of octets of data (including those in bad packets)
received on the network (excluding framing bits but including FCS octets.
etherStatsCRCAlignError
s
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 either a bad FCS with an integral number of octets (FCS Error) or
a bad FCS with a nonintegral number of octets (Alignment Error).
