Table 51: show interfaces bri Field Descriptions

Field	Description
BRI... is {up | down | administratively down}	Indicates whether the interface hardware is currently active (whether line signal is present) and if it has been taken down by an administrator.
line protocol is {up | down | administratively down}	Indicates whether the software processes that handle the line protocol consider the line usable (that is, whether keepalives are successful).
Hardware is	Hardware type.
Internet address is	IP address and subnet mask, followed by packet size.
MTU	Maximum transmission unit 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 (255/255 is 100 percent reliability), calculated as an exponential average over 5 minutes.
load	Load on the interface as a fraction of 255 (255/255 is completely saturated), calculated as an exponential average over 5 minutes.
Encapsulation	Encapsulation method assigned to interface.
loopback	Indicates whether loopback is set or not.
keepalive	Indicates whether keepalives are set or not.
Last input	Number of hours, minutes, and seconds since the last packet was successfully received by an interface. Useful for knowing when a nonfunctioning interface failed.
output	Number of hours, minutes, and seconds since the last packet was successfully transmitted by an interface.
output hang	Number of hours, minutes, and seconds (or never) since the interface was last reset because of a transmission that took too long. When the number of hours in any of the "last" fields exceeds 24 hours, the number of days and hours is printed. If that field overflows, asterisks (**) are printed.
Output queue, drops Input queue, drops	Number of packets in output and input queues. Each number is followed by a slash (/), the maximum size of the queue, and 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 5 minutes.
packets input	Total number of error-free packets received by the system.
bytes	Total number of bytes, including data and media access control (MAC) encapsulation, in the error-free packets received by the system.
no buffer	Number of received packets discarded because there was no buffer space in the main system. Compare with ignored count. Broadcast storms on Ethernets and bursts of noise on serial lines are often responsible for no input buffer events.
broadcasts	Total number of broadcast or multicast packets received by the interface.
runts	Number of packets that are discarded because they are smaller than the medium's minimum packet size.
giants	Number of packets that are discarded because they exceed the medium's maximum packet size.
input errors	Total number of no buffer, runts, giants, CRCs, frame, overrun, ignored, and abort counts. Other input-related errors can also increment the count, so this sum may not balance with the other counts.
CRC	Cyclic redundancy checksum generated by the originating station or far-end device does not match the checksum calculated from the data received. On a serial link, CRCs usually indicate noise, gain hits, or other transmission problems on the data link.
frame	Number of packets received incorrectly having a CRC error and a noninteger number of octets. On a serial line, this is usually the result of noise or other transmission problems.
overrun	Number of times the serial receiver hardware was unable to hand received data to a hardware buffer because the input rate exceeded the receiver's ability to handle the data.
ignored	Number of received packets ignored by the interface because the interface hardware ran low on internal buffers. Broadcast storms and bursts of noise can increase the ignored count.
abort	Illegal sequence of one bits on a serial interface. This usually indicates a clocking problem between the serial interface and the data link equipment.
packets output	Total number of messages sent by the system.
bytes	Total number of bytes, including data and MAC encapsulation, sent by the system.
underruns	Number of times that the transmitter has been running faster than the router can handle. This may never be reported on some interfaces.
output errors	Sum of all errors that prevented the final transmission of datagrams out of the interface being examined. Note that this may not balance with the sum of the enumerated output errors, because some datagrams may have more than one error, and others may have errors that do not fall into any of the specifically tabulated categories.
collisions	Number of collisions. These can occur when you have several devices connected on a multiport line.
interface resets	Number of times an interface has been completely reset. This can happen if packets queued for transmission were not sent within several seconds. On a serial line, this can be caused by a malfunctioning modem that is not supplying the transmit clock signal or by a cable problem. If the system recognizes that the carrier detect line of a serial interface is up, but the line protocol is down, it periodically resets the interface in an effort to restart it. Interface resets can also occur when an interface is looped back or shut down.
restarts	Number of times the controller was restarted because of errors.
carrier transitions	Number of times the carrier detect signal of a serial interface has changed state. Check for modem or line problems if the carrier detect line is changing state often.

Table 52: show interfaces virtual-access Field Descriptions

Field	Description
Virtual-Access ... is {up | down | administratively down}	Indicates whether the interface is currently active (whether carrier detect is present), inactive, or has been taken down by an administrator.
line protocol is {up | down | administratively down}	Indicates whether the software processes that handle the line protocol think the line is usable (that is, whether keepalives are successful).
Hardware is Virtual Access interface	Type of interface. In this case, the interface is a dynamically created virtual access interface existing on a VTY line.
Internet address | interface is unnumbered	IP address, or IP unnumbered for the line. If unnumbered, the output lists the interface and IP address to which the line is assigned (Ethernet0 at 10.0.21.14 in this example).
MTU	Maximum transmission unit for packets on the virtual access interface.
BW	Bandwidth of the virtual access interface in kilobits per second.
DLY	Delay of the virtual access interface in microseconds.
rely	Reliability of the virtual access interface as a fraction of 255 (255/255 is 100% reliability), calculated as an exponential average over five minutes.
load	Load on the virtual access interface as a fraction of 255 (255/255 is completely saturated), calculated as an exponential average over five minutes. The calculation uses the value from the bandwidth interface configuration command.
Encapsulation	Encapsulation method assigned to the virtual access interface.
loopback	Test in which signals are sent and then directed back toward the source at some point along the communication path. Used to test network interface usability.
keepalive	Interval set for keepalive packets on the interface. If keepalives have not been enabled, the message is "keepalive not set."
DTR	Data Terminal Ready. An RS232-C circuit that is activated to let the DCE know when the DTE is ready to send and receive data.
LCP open | closed | req sent	Link control protocol (for PPP only; not for SLIP). LCP must come to the open state before any useful traffic can cross the link.
Open IPCP | IPXCP | ATCP	IPCP is IP control protocol for PPP, IPXCP is IPX control protocol for PPP, ATCP is AppleTalk control protocol for PPP. Network control protocols (NCPs) for the PPP suite. The NCP is negotiated after the LCP opens. The NCP must come into the open state before useful traffic can cross the link.
Last input	Number of hours, minutes, and seconds since the last packet was successfully received by a virtual access interface. Useful for knowing when a dead interface failed.
output	Number of hours, minutes, and seconds since the last packet was successfully transmitted by a virtual access interface.
output hang	Number of hours, minutes, and seconds (or never) since the virtual access interface was last reset because of a transmission that took too long. When the number of hours in any of the "last" fields exceeds 24 hours, the number of days and hours is printed. If that field overflows, asterisks are printed.
Last clearing	Time at which the counters that measure cumulative statistics (such as number of bytes transmitted and received) shown in this report were last reset to zero. Note that variables that might affect routing (for example, load and reliability) are not cleared when the counters are cleared. *** indicates the elapsed time is too large to be displayed. 0:00:00 indicates the counters were cleared more than 231ms (and less than 232ms) ago.
Input queue, drops	Number of packets in input queues. Each number is followed by a slash, the maximum size of the queue, and the number of packets dropped due to a full queue.
Queueing strategy	Type of queueing selected to prioritize network traffic. The options are first-come-first-serve (FCFS) queueing, weighted fair queueing, priority queueing, and custom queueing.
Output queue	Number of packets in output queues. Each number is followed by a slash, the maximum size of the queue, and the number of packets dropped due to a full queue.
Conversations	Number of weighted fair queueing conversations.
Reserved Conversations	Number of reserved weighted fair queueing conversations. The example shows the number of allocated conversations divided by the number of maximum allocated conversations. In this case, there have been 0 reserved conversations.
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	Total number of bytes, including data and MAC encapsulation, in the error free packets received by the system.
no buffer	Number of received packets discarded because there was no buffer space in the main system. Compare with ignored count. Broadcast storms on Ethernets and bursts of noise on serial lines are often responsible for no input buffer events.
broadcasts	Total number of broadcast or multicast packets received by the virtual access interface.
runts	Number of packets that are discarded because they are smaller than the medium's minimum packet size.
giants	Number of packets that are discarded because they exceed the medium's maximum packet size.
input errors	Total number of no buffer, runts, giants, CRCs, frame, overrun, ignored, and abort counts. Other input-related errors can also increment the count, so that this sum might not balance with the other counts.
CRC	Cyclic redundancy checksum generated by the originating LAN station or far end device does not match the checksum calculated from data received. On a LAN, this often indicates noise or transmission problems on the LAN interface or the LAN bus. A high number of CRCs is usually the result of collisions or a station transmitting bad data. On a serial link, CRCs often indicate noise, gain hits or other transmission problems on the data link.
frame	Number of packets received incorrectly having a CRC error and a noninteger number of octets. On a serial line, this is usually the result of noise or other transmission problems.
overrun	Number of times the serial receiver hardware was unable to hand received data to a hardware buffer because the input rate exceeded the receiver's ability to handle the data.
ignored	Number of received packets ignored by the virtual access interface because the interface hardware ran low on internal buffers. These buffers are different than the system buffers mentioned previously in the buffer description. Broadcast storms and bursts of noise can cause the ignored count to be incremented.
abort	Illegal sequence of one bits on a virtual access interface. This usually indicates a clocking problem between the virtual access interface and the data link equipment.
packets output	Total number of messages transmitted by the system.
bytes	Total number of bytes, including data and MAC encapsulation, transmitted by the system.
underruns	Number of times that the far-end transmitter has been running faster than the near-end communication server's receiver can handle. This might never be reported on some virtual access interfaces.
output errors	Sum of all errors that prevented the final transmission of datagrams out of the virtual access interface being examined. Note that this might not balance with the sum of the enumerated output errors, as some datagrams might have more than one error, and others might have errors that do not fall into any of the tabulated categories.
collisions	Number of packets colliding.
interface resets	Number of times a virtual access interface has been completely reset. This can happen if packets queued for transmission were not sent within several seconds. This can be caused by a malfunctioning modem that is not supplying the transmit clock signal, or by a cable problem. If the system notices that the carrier detect line of a virtual access interface is up, but the line protocol is down, it periodically resets the interface in an effort to restart it. Interface resets can also occur when a virtual access interface is looped back or shut down.
restarts	Number of times the controller was restarted because of errors.
carrier transitions	Number of times the carrier detect (CD) signal of a virtual access interface has changed state. Indicates modem or line problems if the CD line changes state often. If data carrier detect (DCD) goes down and comes up, the carrier transition counter increments two times.
output buffer failures	Number of outgoing packets dropped from the output buffer.
output buffers swapped out	Number of times the output buffer was swapped out.

Table 68 describes the screen output for the preceding two examples.

Table 68: show lat sessions Field Descriptions

Field	Description
TTY data	Summary of the LAT-oriented terminal-line-specific data.
Name	Name used for this port as a port identification string. The name is reported to remote systems, which can display it in some operating-system dependent manner. This value is also used for targets of host-initiated connections. Currently, this value is hard-wired to be the line number of the associated terminal line.
Local/Remote usage	Current status of the terminal. The number is reported as current/maximum, where current is the current number of sessions of a given type, and maximum is the maximum number of sessions allowed (or zero if there is no maximum). If a terminal is being used for outgoing sessions, the local usage is equal to the number of current LAT sessions. If the terminal is being used for incoming sessions, local usage is disabled, and the remote count and maximum is one.
Flags	Current state of the line, and whether there are any queued host-initiated connections.
Type flags	Report flags not used in the current software release.
Config flags	Current port state as reflected by the most recent configuration message exchange.
Flow control	Lists set flow control characters.
Groups	Group code list currently in use for the line.
Session data	Reports various parameters about the connection.
Name	For the outbound connection, the name of the remote service to which it is connected. For inbound connections, this field is currently unused.
Remote/Local ID	Slot IDs being used to uniquely identify the session multiplexed over the underlying LAT virtual circuit.
Remote/Local/ Advertised Credits	Number of flow control credits that the Cisco IOS software will be sending to the host as soon as possible. The advertised credits are the number of credits that have already been sent.
Flags	Transient conditions in the LAT-state machine dealing with the current connection status.
Max Data Slot	Maximum number of characters that can be sent in a single data slot.
Max Attn Slot	Maximum amount of data that can be sent in an attention message. Current LAT implementations only sends 1-byte attention messages (attention messages are used to flush buffered output). A nonzero value means that remote data flushing can be used; a zero means that it cannot.
Stop Reason	Reason the session was stopped, if it was stopped but not deleted. This value is usually zero, indicating that the session has not yet been stopped. If a session persists for a long time with a nonzero stop reason, there is probably a problem in the local LAT software.
Remote Node data	Reports information about the remote node. The data includes the same fields as those from the show lat nodes output.
Node	Node name as reported by the host computer.
Address	MAC address of the node's Ethernet interface.
usage	Number of virtual circuits currently active to the node.
Timer	Number of seconds remaining until the node's service advertisement message will time out; this value is set to three times greater than the node's multicast timer value whenever a new service advertisement message is received.
sequence	Sequence number received in the last service advertisement message. Nodes increment their sequence number when the contents of the service advertisement change.
changes	Internal representation of what changed in the multicast message the last time the sequence number changed.
flags	Internal representation of various state information about the node.
protocol	LAT protocol version used by the node.
Recv and Xmit	Number of messages, slots, and bytes received or transmitted to the node. The number of messages is the number of LAT virtual circuit messages. Each virtual circuit message contains some number of slots, which contain actual terminal data or control information.
Dups	Number of duplicate virtual circuit messages received.
ReXmit	Number of virtual circuit messages retransmitted.
Groups	Group codes advertised by the node's service advertisement message.
