The fields displayed by the r option of the swch command are described below:
♦ Note ♦
The first group of statistics are the numbers of bytes
transmitted and received. These are useful in working
out bandwidth usage by the port. Bad octets are impor-
tant to count in the total octets count as they consume
bandwidth at the expense of useful traffic. To ignore
them would lead to mysterious loss of bandwidth in
any calculations performed.
Received Good Octets. The total number of bytes received in good frames.
Received Bad Octets. The total number of bytes received in bad frames.
Total Octets. The total number of octets transmitted or received in good or bad frames on this
port.
Transmitted Good Octets. The total number of bytes successfully transmitted.
Received Unicasts. The number of frames received on this port whose destination address is a
unicast format.
Transmitted Unicasts. The number of frames transmitted on this port whose destination address
is a unicast format.
Received Multicasts. The number of frames received on this port whose destination address is
a multicast format.
Transmitted Multicasts. The number of frames transmitted on this port whose destination
address is a multicast format.
Received Broadcasts. The number of frames received on this port whose destination address is
the broadcast address.
