Table 74 describes the fields shown in the display.

Table 74 show interfaces channel Field Descriptions 

Field
Description

Channel... is up

Indicates whether the interface hardware is active (whether synchronization is achieved on an ESCON channel, or whether operational out is enabled on a parallel channel) and whether it has been taken down by an administrator.

line protocol is up

Indicates whether the software processes that handle the line protocol "think" the line is usable (that is, whether keepalives are successful).

Hardware is

Hardware type.

Internet address is

IP address and subnet mask.

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. The calculation uses the value from the bandwidth interface configuration command.

Encapsulation

Encapsulation method assigned to interface.

loopback

Indicates whether loopbacks are set.

keepalive

Indicates whether keepalives are set.

daughter card

Type of adapter card.

Data transfer rate

Rate of data transfer.

Number of subchannels

Number of subchannels.

Last input

Number of hours, minutes, and seconds since the last packet was successfully received by an interface. Useful for knowing when a dead interface first failed. This counter is updated only when packets are process switched, not when packets are fast switched.

Last output

Number of hours, minutes, and seconds since the last packet was successfully sent by an interface. This counter is updated only when packets are process switched, not when packets are fast switched.

output hang

Number of hours, minutes, and seconds (or never) since the interface was last reset because of data that took too long to send. 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

The time at which the counters that measure cumulative statistics (such as number of bytes sent 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. These asterisks (***) indicate 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.

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 sent 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.

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 buffer, runts, giants, cyclic redundancy checks (CRC), frame, overrun, ignored, and abort counts. Other input-related errors can also increment the count, so that this sum may not balance with the other counts.

CRC

Number of code violation errors seen on the ESCON interface, where a received transmission character is recognized as invalid. On a parallel interface, the number of parity errors seen.

frame

Number of received packets having an incorrect CRC error and a noninteger number of octets. This value is always 0.

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. This value is always 0.

ignored

Number of received packets ignored by the interface because the interface hardware ran low on internal buffers. These buffers are different than the system buffers mentioned previously in the "no buffer" description. Broadcast storms and bursts of noise can cause the ignored count to be increased.

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. This value is always 0.

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

Sum of all errors that prevented the final sending 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.

output errors

Number of output errors.

collisions

Number of collisions detected. This value is always 0.

interface resets

Number of times an interface has been completely reset. This can happen if packets queued for sending were not sent within several seconds. On a serial line, this can be caused by a malfunctioning modem that is not supplying the send clock signal, or by a cable problem. If the system notices 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.

On the CMCC adapter, this may occur if the host software is not requesting data.

restarts

Number of times the controller was restarted because of errors.

Number of hours, minutes, and seconds since the last packet was received by an interface. Useful for knowing when a dead interface failed.

output hang

Number of hours, minutes, and seconds (or never) since the interface was last reset because the data took too long to send. 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 sent per second in the last 5 minutes.

packets input

Total number of error-free packets received by the system.

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.

CRC

Cyclic redundancy check (CRC) generated by the originating LAN station or far-end device does not match the checksum calculated from the data received. On a LAN, this usually indicates noise or problems sending data on the LAN interface or the LAN bus itself. A high number of CRCs is usually the result of a station sending bad data.

frame

Number of packets received incorrectly having a CRC error and a noninteger number of octets.

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. 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 increased.

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 far-end sender has been running faster than the near-end router's receiver can handle. This may never be reported on some interfaces.

output errors

Sum of all errors that prevented the final sending 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

Because a Token Ring cannot have collisions, this statistic is nonzero only if an unusual event occurred when frames were being queued or dequeued by the system software.

interface resets

Number of times an interface has been reset. The interface may be reset by the administrator or automatically when an internal error occurs.

restarts

Should always be zero for Token Ring interfaces.

transitions

Number of times the ring made a transition from up to down, or vice versa. A large number of transitions indicates a problem with the ring or the interface.

Table 78 show llc2 Field Descriptions 

Field
Description

TokenRing0

Name of interface on which the session is established.

DTE=1000.5A59.04F9, 400022224444

Address of the station to which the router is talking on this session. The address is the MAC address of the interface on which the connection is established, except when Local Acknowledgment or SDLC Logical Link Control (SDLLC) is used, in which case the address used by the Cisco IOS software is shown as in this example, following the DTE address and separated by a comma.

SAP=04/04

Other station's and the router's (remote or local) service access point (SAP) for this connection. The SAP is analogous to a "port number" on the router and allows for multiple sessions between the same two stations.

State=NORMAL

Current state of the LLC2 session. The values are:

ADM—Asynchronous Disconnect Mode. A connection is not established, and either end can begin one.

SETUP—Request to begin a connection has been sent to the remote station, and this station is waiting for a response to that request.

RESET—A previously open connection has been reset because of some error by this station, and this station is waiting for a response to that reset command.

D_CONN—This station has requested a normal, expected, end of communications with the remote, and is waiting for a response to that disconnect request.

ERROR—This station has detected an error in communications and has told the other station of this. This station is waiting for a reply to its posting of this error.

NORMAL—Connection between the two sides is fully established, and normal communication is occurring.

BUSY—Normal communication state exists, except busy conditions on this station make it such that this station cannot receive information frames from the other station at this time.

REJECT—Out-of-sequence frame has been detected on this station, and this station has requested that the other resend this information.

AWAIT—Normal communication exists, but this station has had a timer expire, and is trying to recover from it (usually by resending the frame that started the timer).

AWAIT_BUSY—A combination of the AWAIT and BUSY states.

AWAIT_REJ—A combination of the AWAIT and REJECT states.

V(S)=5

Sequence number of the next information frame this station will send.

V(R)=5

Sequence number of the next information frame this station expects to receive from the other station.

Last N(R)=5

Last sequence number of this station's sent frames acknowledged by the remote station.

Local window=7

Number of milliseconds before the next timer, for any reason, goes off.

xid-retry timer 0/60000

Number of milliseconds to wait for a reply to exchange identification (XID) frames before dropping a session. This timer value is in the form of next-time/time-between, where "next-time" is the next time, in milliseconds, that the timer will wake, and "time-between" is the time, in milliseconds, between each timer wakeup. A "next-time" of zero indicates that the timer is not enabled, and will never wake.

ack timer 0/1000

Number of milliseconds to wait before sending an acknowledgment. This timer value is in the form of next-time/time-between, where "next-time" is the next time, in milliseconds, that the timer will wake, and "time-between" is the time, in milliseconds, between each timer wakeup. A "next-time" of zero indicates that the timer is not enabled, and will never wake.

p timer 0/1000

Number of milliseconds to wait for a final response to a poll frame before resending the poll frame. This timer value is in the form of next-time/time-between, where "next-time" is the next time, in milliseconds, that the timer will wake, and "time-between" is the time, in milliseconds, between each timer wakeup. A "next-time" of zero indicates that the timer is not enabled, and will never wake.

idle timer 7768/10000

Number of milliseconds that can pass with no traffic before the LLC2 station sends a Receiver Ready frame. This timer value is in the form of next-time/time-between, where "next-time" is the next time, in milliseconds, that the timer will wake, and "time-between" is the time, in milliseconds, between each timer wakeup. A "next-time" of zero indicates that the timer is not enabled, and will never wake.

rej timer 0/3200

Number of milliseconds to wait for a resend of a rejected frame before sending a reject command to the remote station. This timer value is in the form of next-time/time-between, where "next-time" is the next time, in milliseconds, that the timer will wake, and "time-between" is the time, in milliseconds, between each timer wakeup. A "next-time" of zero indicates that the timer is not enabled, and will never wake.

busy timer 0/9600

Number of milliseconds to wait before repolling a busy remote station. This timer value is in the form of next-time/time-between, where "next-time" is the next time, in milliseconds, that the timer will wake, and "time-between" is the time, in milliseconds, between each timer wakeup. A "next-time" of zero indicates that the timer is not enabled, and will never wake.

ack-delay timer 0/3200

Number of milliseconds to allow incoming information frames to stay unacknowledged. This timer value is in the form of next-time/time-between, where "next-time" is the next time, in milliseconds, that the timer will wake, and "time-between" is the time, in milliseconds, between each timer wakeup. A "next-time" of zero indicates that the timer is not enabled, and will never wake.

12.4(10)

The history keyword was added to provide the history of HPR RTP rate graphs for each RTP connection.


Usage Guidelines

HPR RTP pipes use a unique flow and congestion control algorithm called ARB flow control. ARB allows HPR pipes to measure the network's level of congestion and dynamically adjust the rate of data input into the network, so that the network is highly utilized and congestion is avoided. If actual losses occur, ARB can also react to those losses.

local

(Optional) Indicates that the scope of the display is limited to the types of sessions indicated. Local sessions are those that terminate on the node. Examples include control point (CP)-CP sessions and Dependent Logical Unit Requestor (DLUR)-Dependent Logical Unit Server (DLUS) sessions.

dlur

(Optional) Indicates that the scope of the display is limited to the types of sessions indicated. DLUS sessions are logical unit (LU)-LU sessions passing through the node, which are using the DLUR for dependent session.

intermediate

(Optional) Indicates that the scope of the display is limited to the types of sessions indicated. Intermediate sessions are LU-LU sessions passing through the node and are not DLUR-associated.

name session-name-filter

(Optional) Indicates the fully qualified name (1 to 17 characters). Only sessions that have a local or remote endpoint LU name matching the supplied name are displayed.

pcid pcid-filter

(Optional) Indicates an 8-byte procedure correlation identifier (PCID) specified in hexadecimal form. All sessions matching the PCID filter are displayed.

brief

(Optional) Indicates that one line per session is displayed. The brief version includes PCID, state (active or inactive), session endpoint LU names, and mode.

detail

(Optional) Indicates that a detailed, multiline display that shows all fields returned for the session is displayed.

active

(Optional) Displays the active snasw sessions.

not-active

Usage Guidelines

The keywords and arguments that are available with the show spanning-tree command vary depending on the platform you are using and the network modules that are installed and operational.

Cisco 2600, 3660, and 3845 Series Switches

The valid values for interface interface-type are:

fastethernet—Specifies a Fast Ethernet IEEE 802.3 interface.

port-channel—Specifies an Ethernet channel of interfaces.

Cisco 6500/6000 Catalyst Switches and 7600 Series Routers

The port-channel number values from 257 to 282 are supported on the Content Switching Module (CSM) and the Firewall Services Module (FWSM) only.

The interface-number argument designates the module and port number. Valid values for interface-number depend on the specified interface type and the chassis and module that are used. For example, if you specify a Gigabit Ethernet interface and have a 48-port 10/100BASE-T Ethernet module that is installed in a 13-slot chassis, valid values for the module number are from 2 to 13 and valid values for the port number are from 1 to 48.

When checking spanning tree-active states and you have a large number of VLANs, you can enter the show spanning-tree summary total command. You can display the total number of VLANs without having to scroll through the list of VLANs.

The valid values for interface interface-type are:

fastethernet—Specifies a Fast Ethernet IEEE 802.3 interface.

port-channel—Specifies an Ethernet channel of interfaces.

atm—Specifies an Asynchronous Transfer Mode (ATM) interface.

gigabitethernet—Specifies a Gigabit Ethernet IEEE 802.3z interface.

multilink—Specifies a multilink-group interface.

serial—Specifies a serial interface.

vlan—Specifies a catalyst VLAN interface.

The valid values for keyword pathcoast method are:

append—Appends the redirected output to a URL (supporting the append operation).

begin—Begins with the matching line.

exclude—Excludes matching lines.

include—Includes matching lines.

redirect—Redirects output to a URL.

tee—Copies output to a URL.

When you run the show spanning-tree command for a VLAN or an interface the switch router will display the different port states for the VLAN or interface. The valid spanning-tree port states are listening, learning, forwarding, blocking, disabled, and loopback. See Table 0-92 for definitions of the port states:

Table 0-92 show spanning-tree vlan Command Port States

Field
Definition

LIS

Listening is when the port spanning tree initially starts to listen for BPDU packets for the root bridge.

LRN

Learning is when the port sets the proposal bit on the BPDU packets it sends out

FWD

Forwarding is when the port is sending and listening to BPDU packets and forwarding traffic.

BLK

Blocked is when the port is still sending and listening to BPDU packets but is not forwarding traffic.

DIS

Disabled is when the port is not sending or listening to BPDU packets and is not forwarding traffic.

LBK

Loopback is when the port receives its own BPDU packet back.
