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 53 describes the significant fields shown in the display.

Table 53 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.

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.

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.

Table 54 describes the significant fields shown in the display.

Table 54 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 57 describes the significant fields shown in the display:

Table 57 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

Table 59 describes the significant fields shown in the display.

Table 59 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 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 EXEC 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 (CEF)-switched, virtual access input counters are incremented by the CEF switching function by the formula:

IP len + 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 CEF fast-switched, virtual access counters are incremented by the PPPoE payload size.

Accounting is done for PPPoE, PPPoA PTA and L2X as follows:

•For PPPoE PPP Termination Aggregation (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.

Table 60 describes the significant fields shown in the display.

Table 60 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), is 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 consider the line to be usable (that is, whether keepalives are successful).
Hardware is	Type of interface. In this case, the interface is a dynamically created virtual access interface that exists 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 kbps.
DLY	Delay of the virtual access interface, in microseconds.
reliability	Reliability of the virtual access interface as a fraction of 255 (255/255 is 100 percent 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 the IP control protocol for PPP, IPXCP is the IPX control protocol for PPP, and ATCP is the AppleTalk control protocol for PPP. The network control protocol (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. 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 large to be displayed. Zeros (0:00:00) indicate that the counters were cleared more than 231 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 on account of a full queue.
Queueing strategy	Type of queueing selected to prioritize network traffic. The options are first-come-first-served (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 on account of 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, 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 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 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 that 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 that the output buffer was swapped out.
carrier transitions	Number of times that 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.

Table 61 show ip interface virtual-access Field Descriptions

Field	Description
Virtual-Access1 is up, line protocol is up	Virtual access interface is up and the upper layers consider the line usable.
Interface is unnumbered. Using the address of Ethernet0 (172.21.114.132)	The ip unnumbered ethernet 0 command was included in the virtual template interface cloned on this interface.

Related Commands

Command	Description
ip unnumbered	Enables IP processing on a serial interface without assigning an explicit IP address to the interface.

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

Privileged EXEC

Command History

Release	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.

Examples

The following is sample output from the show ip local pool command when pool groups have not been created:

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 BACKHAUL on DSL 0. Layer 3 output may not apply" is displayed for those users that expect ISDN commands to show the required output.

The following sections in the "Examples" section show how to display and interpret reports from the show isdn command options:

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

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 STANDBY.

The backup D-channel is DSL 1 in state IN SERVICE.

The current active layer 2 DSL is 1.

Table 72 describes the significant fields shown in the previous displays of the show modem command.

Table 72 show modem Field Descriptions 

Field	Description
Mdm	Slot and modem port number. Also, the following modem states can appear to the left of a slot/modem port number: •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.
Out calls	Number of outgoing calls that successfully and unsuccessfully dialed out from an available modem.
Busied Out	Number of modems that have been manually removed from service.
Failed Dial	Number of modems that attempted to dial in to the network but failed to make a connection.
No Answer	Number of modems that detected an incoming ring but failed to answer the call.
Succ Pct.	Successful connection percentage of total available modems.

The following example shows the statistics and current configurations for the manageable modem 2/10, which exists on a V.34 modem card in a Cisco 3600 router. A dash (-) indicates a field that is not available on basic modems. An x indicates a field that is available and active on manageable modems.

The type of display output generated from the show modem slot/port command depends on the version of Cisco IOS software running on the router or access server. For example, the following shows example output for a 56K modem card, which carries digital modems that transmit at 56 kbps. (In truth, 56K modems do not modulate or demodulate data. A pure digital-to-digital connection is made.) See Table 73 for a description of the fields displayed by this modem card.

show modem call-stats

To display the local disconnect reasons for all modems inside an access server or router, use the show modem call-stats command in EXEC mode.

show modem call-stats [slot]

Syntax Description

slot	(Optional) Slot number, which limits the display output to a particular range of modems in the system.

Command Modes

EXEC

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.

Table 74 describes the significant fields shown in the display.

Table 74 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.
