Viewing Statistics
Link state The state of Link Detect on the interface (up or no signal detected).
STP state Enable or Disable STP protocol on the port.
Port state Enable (1) and Disable (2) control for the interface.
Frame Accounting
(Error Free)
• RX octets - number of octets received on the interface (not
including octets in error).
• TX octets - number of octets transmitted from the interface (not
including octets in error).
• RX Packet - number of packets received on the interface (not
including packets in error).
• TX Packet - number of packets transmitted from the interface (not
including packets in error).
RMON (EtherStats) • Drop Events - Number of times the SAN Router missed recording
some RMON data due to a lack of resources. Normally 0.
• Octets - The total number of octets of data (including those in bad
packets) received on the network (excluding framing bits but
including FCS octets). This object can be used as a reasonable
estimate of Ethernet utilization. If greater precision is required, the
etherStatsPkts and etherStatsOctets objects should be sampled
before and after a common interval. The differences in the
sampled values are Pkts and Octets, respectively, and the
number of seconds in the interval is Interval.
These values are used to calculate the Utilization as follows:
Utilization = ((Pkts * 20) + Octets) / Interval * 1, 250, 000) for GE.
Utilization = ((Pkts * 20) + Octets) / Interval * 1 25,000) for FE
The result of this equation is the value Utilization which is the percent
utilization of the Ethernet segment on a scale of 0 to 100 percent.
• Packets - The total number of packets (including bad packets,
Broadcast packets, and multicast packets) received.Broadcast
Packets - The total number of good packets received that were
directed to the broadcast address. Note that this does not include
multicast packets.
• Multicast Packets - 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.
• CRC 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 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).
