|
BVIx is
|
Displays the
state of the specified BVI interface, where
x
is the number of the interface. The possible values are: administratively down,
down, or up.
|
|
line
protocol is
|
Displays the
stateof the line protocol for the BVI interface. The possible values are:
administratively down, down, or up.
| Note
|
The line
protocol state is not the same as the protocol state displayed in the
show ip
interfaces command, because it is the state of Layer 2 (media)
rather than Layer 3 (IP protocol).
|
|
|
Interface
state transitions:
|
Displays the
number of times the interface has changed states.
|
|
Hardware is
|
Displays
Bridge-Group Virtual Interface for a BVI.
|
|
address is
|
Layer 2 MAC
address of the BVI.
|
|
Description:
|
Displays the
description of the interface when configured.
|
|
Internet
address is
n.n.n.n/n
|
Layer 3 IP
address of the BVI in dotted decimal format.
|
|
MTU
|
Displays the
maximum transmission unit (MTU) for the interface. The MTU is the maximum
packet size that can be transmitted over the interface.
1514 is the default.
|
|
BW
x Kbit
|
Displays the
current bandwidth of the interface in kilobits per second.
|
|
Max:
|
Displays the
maximum bandwidth available on the interface in kilobits per second.
|
|
reliability
|
Displays the
proportion of packets that are not dropped and do not have errors.
| Note
|
The
reliability is shown as a fraction of 255.
|
|
|
txload
|
Indicates
the traffic flowing out of the interface as a proportion of the bandwidth.
| Note
|
The txload
is shown as a fraction of 255.
|
|
|
rxload
|
Indicates
the traffic flowing into the interface as a proportion of the bandwidth.
| Note
|
The rxload
is shown as a fraction of 255.
|
|
|
Encapsulation
|
Layer 2
encapsulation on the interface.
|
|
loopback
|
Always
displays “not set” for a BVI because loopbacks are not supported.
|
|
ARP type
|
Address
Resolution Protocol (ARP) type used on the interface.
|
|
ARP timeout
|
ARP timeout
in the format hours:mins:secs. This value is configurable using the
arp timeout
command.
|
|
Last input
|
Number of
hours, minutes, and seconds since the last packet was successfully received by
an interface and processed locally on the router. Useful for knowing when a
dead interface failed.
|
|
output
|
Number of
hours, minutes, and seconds since the last packet was successfully transmitted
by the interface. Useful for knowing when a dead interface failed.
|
|
Last
clearing of “show interface” counters
|
Time since
the counters in this command were last cleared using the
clear
counters Exec command in hours:mins:secs.
|
|
5 minute
input rate
|
Average
number of bits and packets received per second in the last 5 minutes. If the
interface is not in promiscuous mode, it senses network traffic that it sends
and receives (rather than all network traffic).
| Note
|
The
5-minute period referenced in the command output is a load interval that is
configurable under the interface. The default value is 5 minutes.
|
| Note
|
The
5-minute input should be used only as an approximation of traffic per second
during a given 5-minute period. This rate is exponentially weighted average
with a time constant of 5 minutes. A period of four time constants must pass
before the average will be within two percent of the instantaneous rate of a
uniform stream of traffic over that period.
|
|
|
5 minute
output rate
|
Average
number of bits and packets transmitted per second in the last 5 minutes. If the
interface is not in promiscuous mode, it senses network traffic that it sends
and receives (rather than all network traffic).
| Note
|
The
5-minute period referenced in the command output is a load interval that is
configurable under the interface. The default value is 5 minutes.
|

before the average will be within two percent of the instantaneous rate of a
uniform stream of traffic over that period.
|
|
|
packets
input
|
Number of
packets received on the interface that were successfully delivered to higher
layers.
|
|
bytes
|
Number of
bytes received on the interface.
|
|
total input
drops
|
Total number
of valid packets that were dropped after they were received. This includes
packets that were dropped due to configured quality of service (QoS) or access
control list (ACL) policies. This does not include drops due to unknown Layer 3
protocol.
|
|
drops for
unrecognized upper-level protocol
|
Total number
of packets that could not be delivered because the necessary protocol was not
configured on the interface.
|
|
Received
x broadcast packets
|
Total number
of Layer 2 broadcast packets received on the interface. This is a subset of the
total input packet count.
|
|
multicast
packets
|
Total number
of Layer 2 multicast packets received on the interface. This is a subset of the
total input packet count.
|
|
packets
output
|
Number of
packets sent from the interface.
|
|
bytes
|
Total number
of bytes successfully sent from the interface.
|
|
total output
drops
|
Number of
packets that were dropped before being transmitted.
|
|
Output
x broadcast packets
|
Number of
Layer 2 broadcast packets transmitted on the interface. This is a subset of the
total output packet count.
|
|
multicast
packets
|
Total number
of Layer 2 multicast packets received on the interface. This is a subset of the
total output packet count.
