This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.


Usage Guidelines

The dial shelf interconnect (DSI) port adapter connects the Cisco 5814 dial shelf to the Cisco 7206 router shelf. The DSI port adapter allows data transfers between the dial shelf and the router shelf. Data is converted into packets by the feature cards, transmitted to a hub on the dial shelf controller card, and from there sent to the router shelf. Conversely, packets from the router shelf are sent to the dial shelf controller card, where they are transmitted over the backplane to the modem and trunk cards. The show dsi command is used to show information about the dial shelf interconnect hardware, interface, physical link, PCI registers, and address filters.

Examples

The following is sample output from the show dsi command:

Table 47 describes the significant fields shown in the display.

Table 47 show dsi Field Descriptions 

Field
Description

FastEthernet0 ... is up
... is administratively down

Indicates whether the interface hardware is currently active and if it has been taken down by an administrator.

line protocol is

Indicates whether the software processes that handle the line protocol consider the line usable or if it has been taken down by an administrator.

Hardware

Hardware type (for example, MCI Ethernet, SCI,1 CBus2 Ethernet) and address.

Internet address

Internet address followed by 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% 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.

ARP type:

Type of Address Resolution Protocol assigned.

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 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.

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.

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.

Output queue, 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.

5 minute input rate,
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 it sends and receives (rather than all network traffic).

The 5-minute input and output rates should be used only as an approximation of traffic per second during a given 5-minute period. These rates are exponentially weighted averages 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.

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.

Received ... 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. For instance, any Ethernet packet that is less than 64 bytes is considered a runt.

giants

Number of packets that are discarded because they exceed the medium's maximum packet size. For example, any Ethernet packet that is greater than 1518 bytes is considered a giant.

input errors

Includes runts, giants, no buffer, CRC, frame, overrun, and ignored counts. Other input-related errors can also cause the input errors count to be increased, and some datagrams may have more than one error; therefore, this sum may not balance with the sum of enumerated input error counts.

CRC

Cyclic redundancy checksum 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 transmission problems on the LAN interface or the LAN bus itself. A high number of CRCs is usually the result of collisions or a station transmitting bad data.

frame

Number of packets received incorrectly having a CRC error and a noninteger number of octets. On a LAN, this is usually the result of collisions or a malfunctioning Ethernet device.

overrun

Number of times the 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.

abort

Number of packets whose receipt was aborted.

watchdog

Number of times watchdog receive timer expired. It happens when receiving a packet with length greater than 2048.

multicast

Number of multicast packets received.

input packets with dribble condition detected

Dribble bit error indicates that a frame is slightly too long. This frame error counter is incremented just for informational purposes; the router accepts the frame.

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 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, as 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 messages retransmitted due to an Ethernet collision. This is usually the result of an overextended LAN (Ethernet or transceiver cable too long, more than two repeaters between stations, or too many cascaded multiport transceivers). A packet that collides is counted only once in output packets.

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 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.

restarts

Number of times a Type 2 Ethernet controller was restarted because of errors.

babbles

The transmit jabber timer expired.

late collision

Number of late collisions. Late collision happens when a collision occurs after transmitting the preamble.

deferred

Deferred indicates that the chip had to defer while ready to transmit a frame because the carrier was asserted.

lost carrier

Number of times the carrier was lost during transmission.

no carrier

Number of times the carrier was not present during the transmission.

output buffer failures

Number of failed buffers and number of buffers swapped out.

1 SCI = Single Cell Input

2 CBus = Command Bus

Usage Guidelines

Your Cisco AS5800 universal access server uses a protocol used by the Cisco 7206 router shelf to communicate back and forth with the Cisco 5814 dial shelf controller card(s) and feature cards. Although dial shelf interconnect (DSI) configuration is transparent to the user, there are several show commands to help you view your setup, and debug commands to help you troubleshoot your system.

To display a subset of this information, use the show dsip clients, show dsip nodes, show dsip ports, show dsip queue, show dsip tracing, show dsip transport, and show dsip version commands.

This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.


Usage Guidelines

Use this command to see whether a client is actually registered with DSIP and using its services.

Consider the following example: a client "Trunk" seems to be defunct on a particular node with absolutely no input/output activity. The command show dsip ports does not show any Trunk port among its local ports though all other client ports show up. The problem might be that the Trunk client did not even register with DSIP. To confirm this, use the show dsip clients command.

Examples

The following is sample output from the show dsip clients command. This command lists the clients.

Router# show dsip clients

Table 48 describes the significant fields shown in the display.

Table 48 show dsip nodes Field Descriptions 

Field
Description

ID

DSIP uses Cisco's IPC (Inter Process Communication) module for nondata related (client control messages etc.) traffic. A seat or node is a computational element, such as a processor, that can be communicated with using IPC services. A seat is where entities and IPC ports reside. The IPC maintains a seat table which contains the seatids of all the seats in the system. Normally this seatid is a function of the slot number.

Type

Local: Local node.

DSIP: Remote DSIP node.

Name

Each seat (node) has a name to easily identify it. There is only one master node and rest are slave nodes. The master node name is "IPC Master" and the slave node name is "Seat:Slave X", where "X" is the slot number of the node.

Last Sent/Last Heard

Each node maintains two sequence numbers for the last sent and last heard.

Last Sent

Whenever a message is sent out, the "last sent" counter is updated.

Last Heard

Whenever a message is received from a remote node, "last heard" is updated.

Usage Guidelines

The DSIP communication going through the IPC stack uses ports. The creation of a port returns a 32-bit port ID which is the endpoint for communication between two IPC clients.

The show dsip ports command is used to check clients that are up and running:

To see the local ports that are created and the activity on them.

To see the remote ports which are connected and to see the activity on them.

If no options are specified, information is displayed for both local and remote ports.

Table 49 describes the significant fields shown in the display.

Table 49 show dsip ports Field Descriptions 

Field
Description

Client:Portname

Client name and port name. Port Name. The port names can be determined because they are based on a uniform naming convention that includes the following elements:

Client name

Master/slave status

Slot number

Any client can derive the port name of the other client it wants to talk to once it knows its physical location, using the following formula:

Master/Slave Status Port Name Syntax

Master Client-Name:Master, for example, Console:Master

Slave Client-Name:SlaveSlot, for example, Clock:Slave1

Portid

Port ID. The Port ID is a 32-bit identifier comprised of seatid and the port-number. The IPC maintains a seat table which contains the seatids of all the seats in the system. A seat is where clients and ports reside.

The seat ID is a function of the slot number. Port number is the sequential number of the port that is being created on a particular seat, for example: 0,1, 2, etc.

In-Msgs/

The total number of input messages that were received on a particular port.

Out-Msgs

The total number of output messages that were sent to a particular remote port.

Bytes(in/out)

The total number of bytes that were received on a particular port or sent to a remote port. The number of bytes on this port up to the time of the execution of the show command.

Last-i/p

Elapsed time since the last input was received on a local port.

Last-o/p

Elapsed time since the last message was sent to a particular remote port.

Last-act

Elapsed time since the connection to a remote port was opened.

Table 51 describes the significant fields shown in the display:

Table 51 show dsip transport Field Descriptions 

Field
Description

DSIP Transport Statistics:

There are basically three kinds of communication channels between the DSIP modules running on two processors:

1. IPC: DSIP IPC-based reliable/best-effort channel.

2. CNTL: Control packet channel for DSIP modules to communicate between themselves. For example, keepalive messages and initial handshake messages between two DSIP modules are exchanged over this channel.

3. DATA: DSIP fast data packet channel.

input msgs/output msgs

The number of input/output packets on a particular channel.

bytes

The number of input bytes received or sent on a particular channel.

total consumed ipc msgs

The total number of IPC messages consumed so far from the IPC buffer pool.

total freed ipc msgs

The total number of IPC messages returned to the IPC buffer pool so far.

transmit contexts in use

DSIP for each active reliable connection to a remote port keeps a transmit context. This context holds all the important information pertaining to the remote connection, such as, destination portid, port name, number of message and bytes sent to that port etc. This is created when first time a connection is opened to a remote port and is reused for all subsequent communication to that port.

free

Free transmit context is available.

zombie

When DSIP tears down a connection to a remote slot, all the transmit contexts to that slot should return to the free pool. But instead of immediately returning to the free pool, all such contexts first end up on a zombie queue, spend their last few seconds here and then eventually return to the free queue.

invalid

Each transmit context has a magic number. While returning contexts to the free queue, if any transmit context is found to be corrupted, it is marked as invalid and is not returned to the free queue.

ipc getmsg failures

Number of times we failed to get an ipc message.

ipc timeouts

The retry timeouts of the reliable DSIP transport stack.

core getbuffer failures

The number of times DSIP transport layer has failed to allocate buffers for the IPC transport.

aip getbuffer failures

The number of times DSIP transport has failed to allocate buffers while preparing to transmit data received from the clients.

dsip test msgs received/sent

The DSIP test messages received and sent by invoking received/sent the "DSIP Test" client.

DSIP Private Buffer Pool Hits

DSIP by default gets all its buffers from the public buffer pools. If for some reason, it runs out of those buffers, it falls back on a DSIP private pool. This number indicates the number of times DSIP has used this fallback pool.

DSIP Registered Addresses

The MAC addresses of nodes (slots) participating in DSIP communication including the local node. The master sees N slaves whereas slave sees only master (excluding themselves). The information is presented in the following form:

ShelfX: Master | SlotY : MAC Address : Status= local | remote

Indicates whether the interface hardware is currently active (whether line signal is present) and whether 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.

Usage Guidelines

To identify the number of the vty on which the virtual access interface was created, enter the show users command.

The counts of output packet bytes as reported by the L2TP access server (LAC) to the RADIUS server in the accounting record do not match those of a client. The following paragraphs describe how the accounting is done and how you can determine the correct packet byte counts.

Packet counts for client packets in the input path are as follows:

For packets that are process-switched, virtual access input counters are incremented by the coalescing function by the PPP over Ethernet (PPPoE) payload length.

For packets that are fast-switched, virtual access input counters are incremented by the fast-switching function by the formula:

PPPoE payload length + PPP address&control bytes = = PPPoE payload length + 2

For packets that are Cisco Express Forwarding switched, virtual access input counters are incremented by the Cisco Express Forwarding switching function by the formula:

IP length + PPP encapbytes (4) = = PPPoE payload length + 2

Packet counts for client packets in the output path are as follows:

For packets that are process-switched by protocols other than PPP, virtual access output counters are incremented in the upper layer protocol by the entire datagram, as follows:

Size = PPPoE payload + PPPoE hdr (6) + Eth hdr (14) + SNAP hdr (10) + media hdr (4 for ATM)

For packets process-switched by PPP Link Control Protocol (LCP) and Network Control Protocol (NCP), virtual access output counters are incremented by PPP, as follows:

PPP payload size + 4 bytes of PPP hdr

For packets that are Cisco Express Forwarding fast-switched, virtual access counters are incremented by the PPPoE payload size.

Accounting is done for PPPoE, PPPoA PPP Termination Aggregation (PTA), and L2X as follows:

For PPPoE PTA, the PPPoE payload length is counted for all input and output packets.

For PPPoE L2X on a LAC, the PPPoE payload length is counted for all input packets. On an L2TP Network Server (LNS), the payload plus the PPP header (address + control + type) are counted.

For PPP over ATM (PPPoA) PTA i/p packets, the payload plus the PPP address plus control bytes are counted. For PPPoA PTA o/p packets, the payload plus PPP address plus control plus ATM header are counted.

For PPPoA L2X on a LAC for i/p packets, the payload plus PPP addr plus cntl bytes are counted. For PPPoA L2X on a LNS, the payload plus PPP header (address + control + type) are counted.

In Cisco IOS Release 12.2(33)SB and later releases, the router no longer allows you to specify a virtual access interface (VAI) as vix.y in the show pxf cpu queue and show interfaces commands. Instead, you must spell out the VAI as virtual-access.

For example, when you enter the following commands, the router accepts the command:

Router# show interfaces virtual-access 2.1
 
   

In releases prior to Cisco IOS Release 12.2(33)SB, the router accepts the abbreviated form of the VAI. For example, the router accepts the following commands:

Router# show interfaces vi2.1

Maximum transmission unit for packets on the virtual access interface.

BW

Bandwidth of the virtual access interface, in kbps.

DLY

txload, rxload

Load on the virtual access 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.

txload— Transmit load on the virtual access interface as a value of 1/255 calculated as an exponentioal average over 5 minutes.

rxload— Receive load on the virtual access interface as a value of 1/255 calculated as an exponentioal average over 5 minutes.

Encapsulation

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.

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 Serial Line Internet Protocol (SLIP)). LCP must come to the open state before any 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. This value indicates 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 displayed. If that field overflows, asterisks are displayed.

Last clearing

Time at which the counters that measure cumulative statistics (such as number of bytes transmitted and received) 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.

Asterisks (***) indicate that the elapsed time is too lengthy to be displayed.

Zeros (0:00:00) indicate that the counters were cleared more than 231 milliseconds (ms) and less than 232 ms 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 because of a full queue.

Queueing strategy

Type of queueing selected to prioritize network traffic. The options are first-come-first-served (FCFS) queueing, first-in-first-out queueing (FIFO), weighted fair queueing, priority queueing, and custom queueing.

Output queue

Packets in output queues. Represented by the maximum size of the queue followed by a slash and the number of packets dropped because of a full queue. For example, if the output queue is 45/15, 45 is the maximum size of the queue and 15 is the number of packets dropped.

5 minute input rate,
5 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

Total number of no-buffer, runts, giants, cyclic redundancy checks (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

Counter that reflects when the 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 send 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 from the system buffers mentioned in the description of the no buffer field. 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 the far-end transmitter has been running faster than the near-end communication server's receiver can handle. Underruns may 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, because 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. A reset can happen if packets queued for transmission were not sent within several seconds. Resetting 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.

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.

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.

show ip local pool

To display statistics for any defined IP address pools, use the show ip local pool command in privileged EXEC mode.

show ip local pool [poolname | group [group-name]]

Syntax Description

poolname

(Optional) Named IP address pool.

group

(Optional) Displays statistics of all pools in the base system group.

group [group-name]

(Optional) Displays statistics of all pools in the named group.


Command Modes

Modification

11.1

This command was introduced.

12.1(5)DC

This command was enhanced to allow pool group statistics to be displayed.

12.2(13)T

This command was integrated into Cisco IOS Release 12.2(13)T and support was added for the Cisco 6400 node route processor 25v (NRP-25v) Cisco 7400 platforms.


Usage Guidelines

If you omit the poolname argument, the command displays a generic list of all defined address pools and the IP addresses that belong to them. If you specify the poolname argument, the command displays detailed information about that pool.

When you supply the group keyword without the associated group name, the command displays all pools in the base system group. When you supply the group keyword with the associated group name, the command displays all pools in that group.

show isdn

To display the information about memory, Layer 2 and Layer 3 timers, and the status of PRI channels, use the show isdn command in user EXEC or privileged EXEC mode.

show isdn {active [detail] [dsl | serial-number] | call rate [table] | answer [dsl | serial-number] | history [detail] [dsl | serial-number] | memory | service [dsl | serial-number] | status [dsl | serial-number] | timers [dsl | serial-number]}

Syntax Description

active [detail] [dsl | serial-number]

Displays current call information of all ISDN interfaces or, optionally, a specific digital subscriber line (DSL) (created and configured as a serial interface) or a specific ISDN PRI interface. Values of dsl range from 0 to 15. Information includes the called number, the remote node name, the seconds of connect time, the seconds of connect time remaining, the seconds idle, and Advice of Charge (AOC) charging time units used during the call. The detail keyword provides additional information about active calls.

call rate [table]

Displays incoming and outgoing ISDN call switching rate. The optional table keyword presents the data in a tabular format.

answer [dsl | serial-number]

Displays whether a called-party or subaddress number has been configured in the incoming setup message for ISDN BRI calls.

history [detail] [dsl | serial-number]

Displays historic and current call information for all ISDN interfaces or, optionally, a specific DSL (created and configured as a serial interface) or a specific ISDN PRI interface. Values of dsl range from 0 to 15. Information displayed includes the called number, the remote node name, the seconds of connect time, the seconds of connect time remaining, the seconds idle, and AOC charging time units used during the call. The detail keyword provides additional information about historical calls.

11.3

This command was introduced.

12.3

This command was enhanced to display the message "%Q.931 is backhauled to BACKHAUL on DSL 0. Layer 3 output may not apply".


Usage Guidelines

Native ISDN stacks do not know Layer 3 details because Layer 3 is backhauled to an external application. So informational message "%Q.931 is backhauled to IUA BACKHAUL on DSL 3. Layer 3 output may not apply" is displayed for those users that expect ISDN commands to show the required output.

Examples

The following is sample output from the show isdn nfas group command:

Router# show isdn nfas group 1
 
   
%Q.931 is backhauled to IUA BACKHAUL on DSL 3. L3 output may not apply
 
   
ISDN NFAS GROUP 1 ENTRIES:
 
   
The primary D is Serial1/0:23.
The backup D is Serial1/1:23.
The NFAS member is Serial2/0:23.
 
   
There are 3 total nfas members.
There are 93 total available B channels.
The primary D-channel is DSL 0 in state INITIALIZED.
The backup D-channel is DSL 1 in state INITIALIZED.
The current active layer 2 DSL is 1.
 
   

The following three examples show the D-channel state changes when rollover occurs from the primary NFAS D channel to the backup D channel. The first example shows the output with the primary D channel in service and the backup D channel in standby.

Router# show isdn nfas group 0
 
   
%Q.931 is backhauled to IUA BACKHAUL on DSL 3. L3 output may not apply
 
   
ISDN NFAS GROUP 0 ENTRIES:
 
   
The primary D is Serial1/0:23.
The backup D is Serial1/1:23.
The NFAS member is Serial2/0:23.
 
   
There are 3 total nfas members.
There are 70 total available B channels.
The primary D-channel is DSL 0 in state IN SERVICE.
The backup D-channel is DSL 1 in state STANDBY.
The current active layer 2 DSL is 0.
 
   

The following example shows the output during rollover. The configured primary D channel is in maintenance busy state and the backup D channel is waiting.

Router# show isdn nfas group 0
 
   
%Q.931 is backhauled to IUA BACKHAUL on DSL 3. L3 output may not apply
 
   
ISDN NFAS GROUP 0 ENTRIES:
The primary D is Serial1/0:23.
The backup D is Serial1/1:23.
The NFAS member is Serial2/0:23.
 
   
There are 3 total nfas members.
There are 70 total available B channels.
The primary D-channel is DSL 0 in state MAINTENANCE BUSY.
The backup D-channel is DSL 1 in state WAIT.
The current active layer 2 DSL is 1.
 
   

The following example shows the output when rollover is complete. The configured primary D channel is now in standby and the backup D channel is in service.

Router# show isdn nfas group 0
 
   
%Q.931 is backhauled to IUA BACKHAUL on DSL 3. L3 output may not apply

b—Modem was removed from service with the modem shutdown command or the modem busyout command.

B—Modem is suspected to be inoperable or bad. No calls can be made with this modem. The letter B can also mean that a modem firmware download failed for the specified modem. In this case, try unmarking the modem as bad with the no modem bad command and upgrading the modem firmware again.

d—The RAM-based Digital Signal Processor (DSP) code, which supports K56flex, is not configured. The modem will revert to transmitting at 33.6 kbps.

D—Modem is downloading firmware.

p—Firmware download is pending, typically because one or more modems is active.

R—Modem is held and isolated in a suspended state by the modem hold-reset command.

T—Modem is conducting a back-to-back test with another modem.

*—Modem is connected or dialing.

Usage

Percentage of the total system uptime that all modems are in use.

Inc calls

Number of incoming calls that successfully and unsuccessfully connected to a modem.

Command History

Release
Modification

11.3

This command was introduced.

12.2(11)YT

This command was enhanced to display information about digital modems on the Cisco 3600 and 3700 series routers that support the V.92 and V.44 standards.

12.2(15)T

This enhanced command was integrated into Cisco IOS Release 12.2(15)T.


Usage Guidelines

Use this command to find out why a modem ended its connection or why a modem is not operating at peak performance.

Local disconnect reasons for a particular modem are listed across the top of the screen display. For example, see lostCarr, dtrDrop, rmtLink, wdogTimr, compress, retrain, inacTout, and linkFail in the following output:

Router# show modem call-stats
 
   
  dial-in/dial-out call statistics
 
   
       lostCarr  dtrDrop  rmtLink wdogTimr compress  retrain inacTout linkFail
  Mdm 
* 0/0 
* 0/1 
 
   

In the body of the screen display, the number of times an error occurred on a specific modem is displayed (see the # column). The % column shows the total running percent that a modem was logged for the specified disconnect reason with respect to the entire modem pool. For example, out of all the times that the lostCarr error occurred on all the modems in the system, the lostCarr error occurred 2 percent of the time on modem 0/0.

Router# show modem call-stats
 
   
  dial-in/dial-out call statistics
 
   
       lostCarr  dtrDrop  rmtLink wdogTimr compress  retrain inacTout linkFail
  Mdm     #   %    #   %    #   %    #   %    #   %    #   %    #   %    #   %
* 0/0     6   2    2   3    1   0    0   0    0   0    0   0    0   0    0   0
* 0/1     5   2    2   3    2   1    0   0    0   0    0   0    0   0    0   0
 
   

Bad or malfunctioning modems are detected by an unusually high number of disconnect counters for a particular disconnect reason. For example, if modem 1/0 had a high number of compression errors compared to the remaining modems in system, modem 1/0 would probably be bad or inoperable.

To reset the counters displayed by the show modem call-stats command, use the clear modem counters command.


Note Remote disconnect reasons are not described by this command.

Examples

The following example shows call statistics for the show modem call-stats command. Because of the screen size limitation of most terminal screen displays, all the possible disconnect reasons cannot be displayed at the same time. Only the top eight most frequently experienced disconnect reasons are displayed.

Router# show modem call-stats

        lostCarr  dtrDrop  rmtLink wdogTimr compress  retrain inacTout linkFail

Table 68 show modem call-stats Field Descriptions 

Field
Description

dial-in/dial-out call statistics

This category of disconnect reasons can happen only in dial-in or dial-out scenarios.

mohTrmnt

The number of times that a modem is disconnected because Modem on Hold (MOH) terminates. MOH will terminate for two reasons:

MOH clear down by the modem (MICA_DR_MOH_CLEAR_DOWN)

MOH time out (MICA_DR_MOH_TIMEOUT)

wdogTimr

Watchdog timeout. An obscure firmware problem occurred. This is a rare disconnect reason.

compress

Compression. An error was detected during decompression, which caused the internal decompression dictionary to overflow. This could be caused by a modem dialing in that is using a slightly different compression algorithm.

retrain

Retrain failure. A connection was lost and not reestablished after three attempts.

inacTout

Inactivity timeout. The time specified in the AT/T command has expired. No modem data transfers were detected during that period.

linkFail

Link failure. The protocol level link failed while using MNP-10 or LAPM (Link Access Procedure for Modems) in reliable mode.

moduFail

Modulation error. An error was detected at the Digital Signal Processor (DSP) chip level, which caused a disconnect.

mnpProto

MNP10 protocol error. An uncorrectable error occurred during an MNP-10 connection.

lapmProt

LAPM protocol error. An uncorrectable error occurred during a LAPM connection.

lostCarr

Lost carrier. The modem firmware detected a carrier drop during a connection. The cause for the carrier drop could be the loss of signal from the remote modem or the result of a error detection.

dtrDrop

DTR drop. The modem disconnected because the DTR signal from the host became inactive.

userHgup

User hang-up. The modem disconnected because a command such as ATH was detected.

rmtlink

Remote link disconnect. If an MNP-10 reliable link is established, the remote modem sends the disconnect reason across the link before disconnecting. The disconnect reason displayed is LOCAL (remote link disconnect) and REMOTE (the reason the remote modem disconnected).

trminate

Terminate. A password security error occurred in the Microcom High Density Management System (HDMS). This error occurs only with Microcom modems.

callBkfa

Callback failed. This error applies to leased line connections only. A switched line connection failed and a connection still cannot be made on the leased line.

dial-out call statistics

This category of disconnect reasons can happen only in a dial-out scenario.

noCarr

No carrier. The called number answered, but no answer tone was detected after the appropriate wait.

noDitone

No dial tone. No dial tone was detected after the modem went off hook.

busy

Busy. A busy signal was detected while the local modem was attempting to dial.

abort

Abort. A character was received from the remote host after the dial command was issued and before a connection was established.

dialStrg

Dial string error. An invalid character was detected in the dial string, which forced the dial attempt to terminate.

autoLgon

Autologon error. An autologon sequence did not successfully complete.

dialTout

Dial timeout. When a semicolon is used as a dial modifier, the modem returns to the command state as indicated by an "OK." This character allows a continuation of the dial string. If a period of time elapses as specified in the S7 register without the dial string completing, the attempt is aborted with dial timeout as the disconnect reason.

rmtHgup

Remote hang-up. The modem disconnected because the remote modem disconnected the call and dropped DTR.

blacklst

Blacklist. In a country that supports blacklisting, an attempt was made to go off hook with a null dial string (ATD).

ccpNssn

CCP not seen. The credit card prompt (also known as Bong) was not detected.

faxClasz

Fax class 2 error. An abnormal termination to a fax transmission was detected.

Total

Total number of times the disconnect reason occurred among all the modems in the system.


show modem calltracker

To display all information stored within the Call Tracker active or history database for the latest call assigned to a specified modem, use the show modem calltracker command in privileged EXEC mode.

Modification

11.3

This command was introduced.

12.1(5)T

This command was enhanced to display information about digital modems on the Cisco 3600 series routers that support V.110.


Usage Guidelines

Because most terminal screens are not wide enough to display the entire range of connection speeds at one time (for example, 75 to 56000 bps), the max-speed variable is used. This variable specifies the contents of a shifting baud-rate window, which provides you with a snapshot of modem connection speeds for your system. If you want to display a snapshot of lower baud rates, specify a lower connection speed. If you want to see a snapshot of higher baud rates, specify a higher connection speed.

The Cisco IOS software rounds up the max-speed variable to the nearest recognizable baud rate, so you need not memorize or enter exact connection speeds. For example, if you enter a maximum baud rate of 22059, the system software automatically rounds the value up to 24000.

To display a complete picture of all the connection speeds and counters on the system, you must enter a series of commands. Each time you issue the show modem connect-speeds max-speed command, only nine baud rate columns can be displayed at the same time.

Table 71 shows a range of commands that you can issue, one at a time, to display a complete picture of the total possible connection speeds on your access server.

Table 71 Connect Speed Displays for the show modem connect-speeds Command 

Command
Connect Speed Range Displayed

show modem connect-speeds 56000

40000 to 56000 bps

show modem connect-speeds 38000

24000 to 38000 bps

show modem connect-speeds 21600

2400 to 21600 bps

show modem connect-speeds 1200

75 to 1200 bps



Note The Cisco IOS software does not accept commas (,) in the connect speed field. For example, enter 28000 not 28,000.

The show modem connect-speeds command displays a log of connection speed statistics starting from the last time the access servers or router was power cycled or the clear modem counters command was issued. If you want to create a monthly report of the connection speeds achieved by the modems, issue the clear modem counters command at the beginning of the month and issue the show modem connect-speeds command at the end of the month.

This command was introduced.


Usage Guidelines

This command is useful for managing and monitoring multiple versions of modem firmware running in an access server. This command also shows the source location of each version of firmware (for example, running out of Flash or boot Flash memory, or bundled with Cisco IOS software).

Firmware can also be copied from a local TFTP server to the onboard modems. For the Cisco AS5300, issue the copy tftp flash command followed by the copy flash modem command. The Cisco AS5300 stores individual firmware files that are not bundled with the Cisco IOS software in Flash memory. For the Cisco AS5200, issue the copy tftp bootflash command followed by the copy bootflash modem command. The Cisco AS5200 stores individual firmware files not bundled with the Cisco IOS software in boot Flash memory.

All the modems in a single MICA technologies modem module run the same version of firmware (for example, modems 1/0 through 1/5 in module 0). However, different versions of modem firmware can exist between different modem modules (for example, module 0 and module 1).

Individual firmware files cannot be erased from Flash or boot Flash memory. The entire contents of Flash or boot Flash memory must be deleted during the erase operation. If you do this delete, be sure to back up your Cisco IOS software and running configuration before you erase your system's Flash or boot Flash memory.


Note The Cisco AS5800 does not support the show modem mapping command. Use the show modem bundled-firmware command instead.

Examples

The following is sample output from the show modem mapping EXEC command. This access server is loaded with MICA and Microcom modems.

Usage Guidelines

Each MICA modem has its own data channel port, which is tied to its own TTY line. For example, modem 0/1 is tied to TTY line 2. To display data channel information for a single MICA modem, issue the show modem mica slot/port command.

All the modems on each MICA modem card share three pseudochannels for modem management functions, for example, the DC session channel, status polling channel, and controlling channel. To display statistics for each modem management channel, issue the show modem mica all command. The first channel you see displayed is the status polling channel (shown as SLOT/PORT (0/61) TTYNUM=-1 (MM Status Port)). The second displayed channel is the DC session channel (shown as SLOT/PORT (0/60) TTYNUM=-1 (MM DC Port)). The third displayed port is the controlling channel (shown as SLOT/PORT (0/62) TTYNUM=-1 (Control Port)). No TTY lines are associated with the modem management ports, as indicated by the field display TTYNUM=-1. An extensive list of all the data channels for each MICA modem is also displayed.

Table 82 show modem operational-status Field Descriptions for MICA Modems 

Field
Description

Modem (slot/port) Operational Status:

This parameter identifies the modem.

Parameter #0 Disconnect Reason Info:

This parameter displays reasons for call disconnect.

Parameter #1 Connect Protocol:

This parameter displays the connect protocol for the current session, which can be synchronous (SYNC) mode, asynchronous (ASYNC) mode, AppleTalk Remote Access (ARA) 1.0, ARA 2.0, Link Access Procedure for Modems (LAP-M), Microcom Network Protocol (MNP), FAX mode, Signaling System 7/Continuity Test (SS7/COT), or ISDN Mode.

Parameter #2 Compression:

This parameter displays the compression protocol used for the current connection, which can be None, V.42bis TX (transmit), V.42bis RX (receive), V.42bis both, or MNP5 data compression.

Parameter #3 EC Retransmission Count:

This parameter displays the error correction (EC) retransmission count, or the number of times the MICA technologies modem has gone into error recovery in the TX direction for a particular connection.

The higher the number, the worse the connection. However, compare this parameter against the count produced by Parameter #36 (EC packets transmitted, received) to determine if there really is a problem.

Parameter #4 Self Test Error Count:

This parameter displays the total errors generated during a self-test run.

Parameter #5 Call Timer:

This parameter displays the length of the call in seconds. The timer starts when the CONNECT modem state is reached.

Parameter #6 Total Retrains:

This parameter displays the count of total retrains and speed shifts.

Parameter #7 Sq Value:

This parameter displays the measure of the receive signal quality (SQ) bit error rate for the chosen modulation, as estimated by the Digital Signal Processor (DSP), where 0 is the highest BER value and 7 the lowest. Depending on the setting of the SQ Threshold (S32), the DSP seeks an SQ value somewhere between the highest and lowest levels. For example, if S32 = 2 (the default), an SQ value of 3 is sought. If the SQ value drops below the threshold for longer than the duration of S35, the DSP attempts a downward speed shift or retrain. Similarly, if the SQ value goes above the threshold for longer than S34, an upward speed shift or retrain is attempted.

Parameter #8 Connected Standard:

This parameter displays the modulation, which can be V.21, Bell03, V.22, V.22bis, Bell212, V.23, V.32, V.32bis, V.32terbo, V.34, V.34+, K56Flex, V.90, V.110, or ISDN.

Parameter #15 TX, RX Trellis Coding:

Trellis coding adds dependency between symbols to make the detection in noise more robust (Forward Error Correction). Trellis coding is displayed in values of 0, 8, 16, 32, or 64. Use the following key to correlate the trellis code values with the connection standard:

0—V.22, V.22bis, V.21, Bell212, Bell103, V.29, or V.27

8—V.32, V.32bis, or V.17

16, 32, 64—V.34, V.34+, V.90, K56Flex

Note MICA technologies modems do not support values of 32 or 64 in the RX direction, but do support values of 16, 32, and 64 in the TX direction.

Parameter #16 TX, RX Preemphasis Index:

The preemphasis index involves shaping the raw transmit spectrum to deal with spectrum roll-offs. The preemphasis index can take on the values from 0 to 10. A zero denotes no reshaping. Typical values usually fall in the range from 0 to 2, or 6 to 7. This index is used with V.34 and V.34+ connection standards.

Parameter #17 TX, RX Constellation Shaping:

Constellation shaping is a technique for improving noise immunity by using a probability distribution for transmitted signal points. The signal states are used to predict the sensitivity to certain transmission impairments. Constellation shaping is used with the V.34 and V.34+ connection standards.

Values displayed by this parameter are either none or active (Off or On).

Parameter #18 TX, RX Nonlinear Encoding:

Nonlinear encoding occurs during the training phase and moves the outer points of the constellation away to deal with nonlinear distortion. Nonlinear distortion (in the range from 0 to 200 Hz) tends to affect the higher-powered signals. Moving the outer constellation points out reduces the chance of error. Nonlinear encoding is used with the V.34 and V.34+ connection standards.

Values displayed by this parameter are either none or active (Off or On).

Note MICA technologies modems support nonlinear coding in both directions.

Parameter #19 TX, RX Precoding:

Precoding serves the same purpose as the preemphasis index, but instead manages the bits and not the raw transmit signals. This management is done only when asked for and therefore will occur only in the RX mode. Precoding is used with the V.34 and V.34+ connection standards.

Values displayed by this parameter are either none or active (Off or On).

Parameter #20 TX, RX Xmit Level Reduction:

The Xmit (transmit) level affects the transmit signal with 0 to 15 in dBm of reduction. If nonlinear distortion is detected, the MICA technologies modem will request a lower-powered TX signal. If the remote end detects nonlinear distortion, it will also request a lower-powered TX signal. Xmit level reduction is used with the V.34 and V.34+ connection standards.

Values displayed by this parameter are the transmit signal and reduction, in dBm.

Parameter #21 Signal Noise Ratio:

A signal to noise ratio (SNR) is the ratio between the expected signal and the error signal.

For example, consider a four-point constellation at (x,y) = (-1,1), (1,1), (1,-1), and (-1,-1). The receive signal comes in at (x^,y^) = (0.5,1.5). The expected value, although not guaranteed, is (1,1). The error vector is then calculated as follows:

e = (x - x^, y - y^) = ([1-0.5], [1-1.5]) = (0.5,-0.5)

and the SNR is calculated as follows:

SNR = 20*log10 [magnitude(expected value x,y of constellation) /
magnitude(error)]

SNR = 20 log10 [magnitude(1,1) / magnitude(0.5,-0.5)] = 6.02 dB

This parameter displays the ratio measurement of the desired signal to noise. MICA technologies modems measure the SNR in only the signal band that has a rate equal to the baud rate (that is, 3200 Hz, 2400 Hz, and so on).

Note that a 28.8-kbps connection demands an SNR of about 37 dB. If the rate is lower than this value, the quality of the connection diminishes. A 33.6-kbps connection demands an SNR of 38 to 39 dB. A clean line has an SNR of about 41 dB.

The values displayed by this parameter range from 0 to 70 decibels (dB) and change in 1-dB steps.

Parameter #22 Receive Level:

The receive level is the power of the received signal and ranges from 0 to -128 dBm in 1-dBm incremental steps. The ideal range is about -22 dBm in the United States and -12 dBm in Europe.

In theory, MICA technologies modems can handle a receive level up to -4 dBm. However, the receive level they can handle is a function of the echo level. If there is absolutely no echo, the MICA modem should be able to handle a -4 dBm level. As the echo level goes up, the receive level that the MICA modem can handle moves from -4 dBm to -5 dBm, and so on.

The optimum range for the receive level displayed by this parameter is from -12 dBm to -24 dBm.

Parameter #23 Frequency Offset:

Frequency offset is a difference between the modulation carriersthat is, the frequency shift in the receive spectrum between the expected RX carrier frequency and the actual RX carrier frequency.

The values displayed by this parameter range from +/-32 in 0.125-Hz steps. The typical value is 0 Hz.

Note Values of up to +/-7 Hz can be found on analog trunk circuits and will be compensated for by the MICA technologies modems.

Parameter #24 Phase Jitter Frequency:

Phase jitter frequency is the peak-to-peak differential between two signal points.

The following calculation models a typical RX carrier:

e^j(wt + a)

but when phase jitter is detected, the RX carrier is modeled as follows:

e^j[wt + a + K sin(bt + c)]

where:
w = carrier frequency

a = carrier phase

K = magnitude of sinusoidal phase jitter

b = frequency of sinusoidal phase jitter

c = phase of sinusoidal phase jitter

Uncanceled phase jitter looks like "rocking" of the baseband QAM constellation. The points look like arcs with the outer points having longer arcs.

The phase jitter measurements displayed by this parameter range from +/-32 in 0.125-Hz steps. The typical value is 0 degrees (that is, phase jitter is not normally present).

Note This phase jitter value is found only on analog trunk circuits. Typical frequencies are power generation frequencies and their harmonics (that is, 60, 120 Hz within the United States; 50, 100 Hz international). MICA technologies modems cancel all known frequencies.

Parameter #25 Phase Jitter Level:

Phase jitter level is the amount of phase jitter measured and indicates how large the "rocking" is, in degrees. On an oscilloscope, the constellation points would look like crescent moons. The jitter level corresponds to magnitude K as described in Parameter #24.

Values displayed by this parameter can range up to 15 degrees. The typical value is 0 degrees (that is, phase jitter is not normally present).

Parameter #26 Far End Echo Level:

Over long connections, an echo is produced by impedance mismatches at 2-wire-to-4-wire and at 4-wire-to-2-wire hybrid circuitry.

This parameter displays the far-end echo level (that portion of the transmitted analog signal that has bounced off of the analog front end of the remote modem), which can range from 0 to -90 dBm.

A MICA modem cannot handle near-end echo if far-end echo is present and the round-trip delay is greater than 10 microseconds. This constraint comes from the number of taps in the echo canceler of MICA modems.

Assuming that there is no near-end echo, the performance of the receiver varies as the ratio of the receive level divided by the far-end echo (RECEIVE LEVEL/FAR END ECHO). As the echo level rises, the receiver performance degrades. (This is why the MICA modem can handle "hotter" receive levels with less echo.)

The technical reason for this degradation has to do with dynamic range. Every echo canceler has some residual echo (error) left in the signal. This residual echo adds to the power of the receive signal going through the rest of the MICA modem receiver. With little residual echo, there is more dynamic range for the actual receive signal.

For a call to go from the MICA modem to the local switch and back into MICA, the reported far-end echo level must be less than -55 dBm. A greater echo level indicates a digital-to-analog conversion in the path between the MICA modem and the switch. MICA modems are not supported in this topology.

Parameter #27 Phase Roll:

This parameter displays the phase roll, which affects the echo signal coming back to the MICA modem.

A certain constellation pattern is transmitted from a MICA modem when the echo signal reaches the central office (CO). Some echoed form of this signal/constellation pattern is sent back to the MICA modem; however, the constellation shape may be rotated from 0 to 359 degrees. This rotation is called the phase roll.

The echoed signal consists of a frequency component and a phase component. If the frequency component changes at all, a correction is needed for echo cancellation to work correctly. A slight variance (an unknown amount that would have to be determined through experimentation) in the phase may not affect how the echo canceler performs. Too much change in phase also needs correcting for proper echo cancellation to occur.

The phase roll value ranges from +/-32 in 0.125-Hz steps. The typical value is 0 or close to 0.

Parameter #28 Round Trip Delay:

Round-trip delay is the total round-trip propagation delay of the link in microseconds. This delay is important for proper echo cancellation.

This parameter displays the round-trip delay; the amount of delay varies with each network.

Note The buffer speed for MICA modems is 4096 bps; therefore, at 2400 bps the delay is 1.7 seconds, and at 3429 bps, 1.19 seconds. Because round-trip delay is measured before the bps rate is chosen, round-trip delay is used to disable those bit rates for which the round-trip delay cannot be supported. For example, if the round trip-delay is 1.25 seconds, 3429 is disabled for that train attempt.

Parameter #30 Characters transmitted, received:

This parameter displays the total count of characters (before modem compression of any type) received and transmitted.

Parameter #32 General Portware Information:

Not used.

Parameter #33 PPP/SLIP packets transmitted, received:

This parameter displays the total count of Point-to-Point Protocol (PPP) and Serial Line Internet Protocol (SLIP) packets transmitted and received. This total could include all PPP/SLIP packets, including BAD/ABORTED packets.

Parameter #35 PPP/SLIP packets received (BAD/ABORTED):

This parameter displays the total count of the bad or aborted PPP/SLIP packets, and is a subset of the counter shown in Parameter #33 (PPP/SLIP packets received). A counted PPP packet has a bad FCS, or the SLIP packet has a transparency error. Errored PPP frames should be displayed only when asynchronous framing (no EC protocol) is being used.

Parameter #36 EC packets transmitted, received OK:

This parameter displays the number of EC packets transmitted (the number of TX frames that the client modem has accepted) and the number of EC packets received (the number of RX frames that the MICA modem has accepted).

Parameter #38 EC packets (Received BAD/ABORTED):

Parameter #38 is identical to Parameter #3 (EC Retransmission Count). It may read differently from Parameter #3, depending on how the software requests the parameter information.

Parameter #39 Robbed Bit Signalling (RBS) pattern:

This parameter displays the number of robbed bits detected in the connection. The robbed bits are used for in-band signaling. This information is reported only for K56Flex by the analog modem. The six least significant bits of the returned value indicate the periodic RBS pattern, where a 1 denotes a pulse code modulation sample with a robbed bit.

Parameter #40 Digital Pad, Digital Pad Compensation:

A digital pad can be implemented by the CO to attenuate a "hot" signal. Compensation boosts the signal by the amount of the pad.

This parameter displays values that usually range from 0 to 10 dB, with typical values being 0, 3, and 6 dB.

Note A digital pad is mandatory for K56Flex, but configurable for V.90 using S52. K56Flex supports only 0, 3, and 6 dB. V.90 supports steps of 1/8192 dB, but it is reported to the host in steps of 0.125-dB granularity.

Line Shape:

The display at the end of the report shows line shaping as a frequency-response graph of the channel. The Y (vertical) axis represents frequencies from 150 Hz (top of chart) to 3750 Hz (bottom of chart) in 150-Hz steps. The X (horizontal) axis represents a normalized amplitude. The graph can help identify nulls, bandwidth, and distortion (irregular shape). A flat spectrum plot is best.

This display is available only for V.34, V.90, and K56Flex connection standards.

This command was enhanced to display service processing element (SPE) features. The "-/-" in the DSP REV field indicates that the spe configuration commands for firmware download are unavailable on that modem.


Usage Guidelines

This command is useful for verifying the version of modem firmware running on the system before or after a modem firmware upgrade. If there is a "-/-" in the DSP REV field, you cannot use the spe configuration commands for firmware download on that modem.

Examples

The following example displays information for modem firmware, which includes modem firmware version, boot code version, controller and DSP code version (56K modem modules only), modem board hardware version, and carrier card information. This particular example displays information for Microcom 56K modem cards (modules 0/0, 2/0, and 2/1) and V.34 cards (module 0/1) installed in a Cisco AS5200.

If the version number is displayed as 0.0.0, verify that out-of-band status polling is functioning.

This command was introduced.


Usage Guidelines

When a modem name is supplied, this command displays the available modem values.

As an alternative to repeatedly entering the same data, use templates as a way to join modemcap entries. For example, consider the following modemcap entries:

modemcap entry gv_basics:FD=&F:AA=S0=1:CD=&C1:DTR=&D2:NEC=E0:NRS=Q1
modemcap entry global_village:HFL=&K3\\X1:BCP=%C1:NCP=%C0:TPL=gv_basics
modemcap entry gv_teleport:NCP=%C0:TPL=gv_basics
 
   

To look up the factory default for a global_village modem, perform the following steps:


Step 1 Look at the global_village modemcap entry for the factory default (FD).

Step 2 If you fail to find FD in global_village, look at the global_village modemcap entry for a template (TPL).

Step 3 Find a TPL called "gv_basics."

Step 4 Look in the gv_basics modemcap entry for the FD.

Step 5 Find FD=&F in the gv_basics modemcap entry.

Step 6 Use &F as the FD for the global_village.

Table 87 identifies and describes the list of attributes.

Table 87 Modem Attributes 

Modem Attribute
Description

Factory defaults (FD)

Returns the modem to factory default configuration. This is commonly "&F."

Autoanswer (AA)

Sets the modem to answer the phone if data terminal ready (DTR) is high, preferably on the first ring. This is commonly "S0=1."

Carrier detect (CD)

Instructs the modem to raise the CD signal when a carrier is detected. Cisco configures modems into auto-answer mode by default. This is not the default for most modems, which just raise CD and leave it high. This is commonly "&C1."

In auto-answer mode, the modem waits until it detects a ring, then responds to the incoming call and negotiates an end-to-end connection with the other modem. At this point, the modem receiving the call informs the router that it has a call ready to be processed; this notification is performed by raising the signal on EIA/TIA-232 pin 8 (the Data Carrier Detect signal) to high.

Drop with DTR (DTR)

Drops the connection if DTR signal drops. There is frequently an option to reset the configuration while this drop occurs; however, this option should not be used. The connection should only drop. The correct value for this is commonly "&D2."

Set Hardware Flowcontrol (HFL)

Uses ready to send/clear to send (RTS/CTS) out-of-band flow control.

Set Software flowcontrol (SFL)

Uses transmit on/transmit off (XON/XOFF) in-band flow control.

Lock DTE speed (SPD)

Instructs the modem to lock the speed at which it communicates to the router to a single rate, preferably the highest. This attribute is important and is often hard to find in manuals.

SPD is often linked to the hardware flow control variable. Look for phrases like "bps rate adjust" and "bit rate adjust."

Some modems set the speed to a value that depends on an S-register; other modems simply lock to the speed that was used when the last AT command was issued. Locking to the speed that was last used is handled automatically. To enable the S-register to set the speed, you must include the proper S-register value for the fastest possible DTE speed.

Best Error Control (BER)

Instructs the modem to negotiate its best error control with remote modems. For ARAP users, this is Microcom Network Protocol (MNP) 5/Link Access Procedure, Balanced (LAPB), but not MNP4.

Best Compression (BCP)

Instructs the modem to negotiate its best compression with remote modems.

No Error Control (NER)

Instructs the modem to negotiate no error control with remote modems. This attribute will be used when placing outgoing (callback) AppleTalk Remote Access protocol (ARAP) calls.

No Compression (NCP)

Instructs the modem to negotiate no compression with remote modems. This attribute is used when placing outgoing (callback) ARAP calls.

No Echo (NEC)

Requests the modem not to echo characters. This attribute is commonly "E0."

No Result Codes (NRS)

Requests the modem not to send a response when you issue a command. This attribute is commonly "Q1."

Caller ID (CID)

Requests that Caller ID information be returned when dial in occurs. Not used.

Miscellaneous (MSC)

Sends any extra commands that are needed for the modem to work (possibly with specific platforms).

Template entry (TPL)

This is the name of another modem type. It is referenced as the value of any of the previously listed attributes if they are not set on the current modem type.

Examples

In the following example, two modem pools are set up: v90service and v34service. Each pool contains one Dialed Number Information Service (DNIS) number: 1234 and 5678, respectively. Each DNIS number is allowed a maximum of 48 simultaneous connections. A total of 96 modems are assigned to the modem pools: 48 and 48, respectively. Modems that are left unassigned to modem pools are automatically put into the default modem pool (displayed as System-def-Mpool). The default pool is empty in this example.

Router# show modem-pool
