Table 5-4 show interface cable Command Field Descriptions
Field Description
Cable slot/port is
up/...administratively down
Indicates whether the interface hardware is currently active or
taken down by the administrator.
line protocol is
up/...administratively down
Indicates whether the software processes that handle the line
protocol believe the interface is usable or if it has been taken down
by the administrator.
hardware
Hardware type and address.
Internet address
Internet address followed by subnet mask.
MTU
Maximum Transmission Unit (MTU) of the interface.
BW
Bandwidth of the interface in kilobits per second.
DLY
Delay of the interface in microseconds.
rely
Reliability of the interface as a fraction of 255, calculated as an
exponential average over 5 minutes. (For example, 255/255 is
100% reliability).
load
Load on the interface as a fraction of 255, calculated as an
exponential average over 5 minutes. (For example, 255/255 is
complete saturation.)
Encapsulation
Encapsulation method assigned to this interface.
ARP type
Type of Address Resolution Protocol (ARP) and timeout value
assigned.
Last input
Number of hours, minutes, and seconds since the last packet was
successfully received by an interface.
output
Number of hours, minutes, and seconds since the last packet was
successfully transmitted by an interface.
Last clearing of “show
interface” counters
Time when the counters that measure cumulative statistics, such as
number of bytes transmitted and received, were last reset to zero.
Queuing strategy
Displays the type of queuing configured for this interface. In the
example output, the type of queuing configured is First In First Out
(FIFO).
Output queue
Number of packets in the output queue. The format of this number
is A/B where A indicates the number of packets in the queue, and
B indicates the maximum number of packets allowed in the queue.
drops
Indicates the number of packets dropped due to a full queue.
input queue/drops
Number of packets in the input queue. The format of this number
is A/B where A indicates the number of packets in the queue, and
B indicates the maximum number of packets allowed in the queue.
drops
Indicates the number of packets dropped due to a full queue.
Five minute input rate
Five minute output rate
Average number of bits and packets transmitted per second in the
last five minutes.
packets input
Total number of error-free packets received by the system.
bytes input
Total number of bytes, including data and MAC encapsulation, in
the error-free packets received by the system.
