Saving Configuration Changes

Follow the procedures in this chapter to configure the Cisco IAD manually or, if you wish, to change the configuration after you have run the setup command facility (see the "The setup Command Facility" section on page 2-2).

This chapter does not describe every configuration possible—only a small portion of the most commonly used configuration procedures. For advanced configuration topics, see the Cisco IOS configuration guide and command reference publications. See the "Obtaining Documentation and Submitting a Service Request" section on page -ix.


Note If you skipped Chapter 2, "Using the setup Command Facility," and you have never configured a Cisco IAD, return to Chapter 2, "Using the setup Command Facility," and read it now. The chapter contains important information that you need for configuring your Cisco IAD.



Note The Cisco IAD2435 router is a fixed-configuration router and does not support interface cards.



Note The Cisco IAD2435 IAD does not support loss plan or idle voltage features available on other Cisco IAD2430 series IADs.


Configuring the Hostname and Password

One of the first configuration tasks is to configure the hostname and set an encrypted password. Configuring a hostname allows you to distinguish multiple Cisco IADs and routers from each other. Setting an encrypted password allows you to prevent unauthorized configuration changes.


Note A hostname can be specified only when the router has a DNS server available for hostname resolution.


To configure the hostname and password, perform the following steps.

SUMMARY STEPS

1. enable

2. configure terminal

3. hostname

4. enable secret password

5. line-console

6. exec-timeout

7. exit

8. end

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

enable

Example:

Router# enable

Enters privileged EXEC mode.

Step 2 

configure terminal

Example:

Router# configure terminal

Enters global configuration mode.

Step 3 

hostname

Example:

Router(config)# hostname IAD2430

Changes the name of the Cisco IAD to a meaningful name.

Step 4 

enable secret password

Example:

Router(config)# enable secret guessme

Enters an enable secret password. This password provides access to privileged EXEC mode. When you press Enter at the user EXEC prompt
(Router>), you must enter the enable secret password to gain access to configuration mode. Substitute your enable secret password for guessme.

Step 5 

line console

Example:

Router(config)# line console 0

Enters line configuration mode to configure the console port. When you enter line configuration mode, the prompt changes to Router(config-line)#.

Step 6 

exec-timeout

Example:

Router(config-line)# exec-timeout 0 0

If no input is detected during the interval, the EXEC facility resumes the current connection. If no connections exist, the EXEC facility returns the terminal to the idle state and disconnects the incoming session.

Note To specify no timeout, enter the exec-timeout 0 0 command.

Step 7 

exit

Example:

Router(config-line)# exit

Exits to global configuration mode.

Step 8 

end

Example:

Router(config-if)# end

Returns you to privileged EXEC mode.

Verifying the Hostname and Password

To verify that you configured the correct hostname and password, follow these steps:


Step 1 Enter the show config command:

Router(config)# show config

Using 1888 out of 126968 bytes
!
version XX.X
.
.
.
!
hostname IAD2430
!
enable secret 5 $1$60L4$X2JYOwoDc0.kqa1loO/w8/
.
.
.

Check the hostname and encrypted password displayed near the top of the command output.

Step 2 Exit global configuration mode and attempt to reenter it, using the new enable password:

Router# exit
.
.
.
Router con0 is now available
Press RETURN to get started.
Router> enable
Password: guessme
Router#



Tip If you are having trouble, ensure the following:

Caps Lock is off.

You entered the correct passwords. Passwords are case sensitive.


Configuring Fast Ethernet Interfaces

To configure a Fast Ethernet interface, use the configuration software provided with your Cisco IAD or network module, if any. Otherwise, for greatest power and flexibility, use configuration mode (manual configuration).


Note Before you begin, disconnect all WAN cables from the Cisco IAD to prevent it from running the AutoInstall process. Whenever you power on the Cisco IAD, if there is a WAN connection on both ends and the Cisco IAD does not have a valid configuration file stored in NVRAM (for instance, when you add a new interface), the Cisco IAD tries to run AutoInstall. It can take several minutes for the Cisco IAD to determine that AutoInstall is not connected to a remote TCP/IP host.


This section describes basic Fast Ethernet interface configuration, including enabling the interface and specifying IP routing. Depending on your own requirements and the protocols you plan to route, you might also need to enter other configuration commands.

Before you begin configuring the interfaces, make sure to do the following:

Connect a console to the Cisco IAD.

Power on the Cisco IAD.

To configure Fast Ethernet interfaces, perform the following steps.

SUMMARY STEPS

1. enable

2. configure terminal

3. ip routing

4. interface type number

5. ip address ip address subnet mask

Enables routing protocols as required for your global configuration. This example uses IP routing.

Step 4 

interface type number

Example:

Router(config)# interface fastethernet 0/0

Enters interface configuration mode. You have entered interface configuration mode when the prompt changes to Router(config-if)#.

Step 5 

ip address ip address subnet mask

Example:

Router(config-if)# ip address 172.16.74.3 255.255.255.0

Assigns an IP address and subnet mask to the interface.

Step 6 

exit

Example:

Router(config-if)# exit

Exits to global configuration mode.

Repeat Step 4 through Step 6 if your Cisco IAD has more than one interface to configure.

Step 7 

Ctrl-z

Example:

Router# Ctrl-z

Returns to enable mode when you finish configuring the interfaces.

Configuring Network Clock

At initialization, all controllers on the Cisco IAD2430 IAD, including onboard T1/E1 or VWIC T1/E1, participate in the system clock domain. The default network clock algorithm selects one of the controllers as a default network clock. The default network clock algorithm provides a best estimate of the clocking system. This is mainly for voice applications to be configured easily after power up.

Cisco recommends that when you power up the system, make sure that network clocks are configured properly for the applications to work, with consideration for the specific network system requirements.

To view the current primary clock, use the show network-clocks or show run command. Note that the show network-clocks and show run commands do not display the default network clock, which is selected by the default network clock algorithm.

To have the T1/E1 controller participate as a clock source for the Cisco IAD system clock domain and to make sure it is available as a candidate for a clock selection algorithm, use the following CLI configuration. If you have data applications that do not require clock participation, use the no form of the commands.

To configure the network clock, perform the following steps.

SUMMARY STEPS

1. enable

2. configure terminal

3. network-clock-participate slot/port

4. controller {t1 | e1 | j1} slot/port

5. network-clock-participate slot/port

6. network-clock-select priority bri|atm|t1|e1 slot/port

7. network-clock-select priority serial slot/port

8. exit

9. Ctrl-z

Example:

Router# configure terminal

Enters global configuration mode.

Step 3 

network-clock-participate slot/port

Example:

Router(config)# network-clock-participate WIC 0

Enters the controller into the system clock domain.

Note The IAD2435 IAD is configured with network-clock-participate by default. You cannot remove or configure this default configuration.

Step 4 

controller t1 slot/port

Example:

Router(config)# controller t1 0/2

Enters the first part of the VWIC controller at slot 0 into the system clock domain.

Step 5 

network-clock-participate slot/port

Example:

Router(config-controller)# controller t1 0/2

Router(config-controller)# network-clock-participate wic 0

Enters both parts of the VWIC controller at slot 0 into the system clock domain.

Step 6 

network-clock-select priority {bri|atm|t1|e1} slot/port

Example:

Router(config)# network-clock-select 1 T1 1/0

Selects the controller as a candidate for the clock selection algorithm according to the priority entered. Use either slots 1/0 or 0/0.

Step 7 

network-clock-select priority serial slot/port

Example:

Router(config)# network-clock-select 1 Serial 0/0

In case of a serial interface, selects the serial controller as a candidate for the clock selection algorithm according to the priority entered. This applies only when the serial interface is used for time-division multiplexing (TDM) connections.

Step 8 

exit

Example:

Router(config-if)# exit

Exits to global configuration mode.

Step 9 

Ctrl-z

Example:

Router#

Returns to enable mode when you finish configuring interfaces.

Configuring T1/E1 Interfaces

To configure an ISDN PRI, channel-associated signaling (CAS) interface, or a T1/E1 multiflex trunk interface, use the configuration software provided with your Cisco IAD or network module (if any). Otherwise, for greatest power and flexibility, use configuration mode (manual configuration). In this mode, you enter Cisco IOS commands at the prompt.

This section covers the following topics:

Configuring Channel Groups on T1/E1 to Support Data

Configuring Channel Groups on T1/E1 to Support Data Under SHDSL Controller

Configuring Digital Voice on T1/E1

Configuring TDM Cross-Connect


Note Before you begin, disconnect all WAN cables from the Cisco IAD to prevent it from running the AutoInstall process. Whenever you power on the Cisco IAD, if there is a WAN connection on both ends and the Cisco IAD does not have a valid configuration file stored in NVRAM (for instance, when you add a new interface), the Cisco IAD tries to run AutoInstall. It can take several minutes for the Cisco IAD to determine that AutoInstall is not connected to a remote TCP/IP host.


This section describes basic configuration, including enabling the interface and specifying IP routing. Depending on your own requirements and the protocols that you plan to route, you might need to enter additional configuration commands.

Before you begin configuring the interfaces, make sure to do the following:

Connect a console to the Cisco IAD.

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

enable

Example:

Router# enable

Enters privileged EXEC mode.

Step 2 

configure terminal

Example:

Router# configure terminal

Enters global configuration mode.

Step 3 

controller t1/e1 slot/port

Example:

Router(config)# controller t1 0/2

Enters controller configuration mode for controller 1 (the trunk controller for the T1-PBX port).

Note DS0-group number should be different from channel-group number and TDM-group number under the same controller.

Step 4 

mode css

Example:

Router(config-controller)# mode css

Enters CAS configuration mode and configures the T1/E1 trunk to support signaling that matches the PBX signaling type:

cas—Channel-associated signaling

Common channel signaling cross-connect—CCS cross-connect for bearer channels

ccs frame-forwarding—CCS transparent signaling

Step 5 

ds0-group ds0-group-number timeslots timeslot-list

Example:

Router(config-controller-cas)# ds0-group 1 timeslots 1-4

Creates a DS0 group on the T1/E1 trunk. A DS0 group can contain from 1 to 24 time slots numbered from 0 to 23 for T1, and 1 to 32 time slots numbered from 0 to 31 for E1.

Note The maximum number of time slots available in a T1 DS0 group is 24. The maximum number of time slots available in an E1 DS0 group is 32.

Note You can configure a maximum of 8 time slots in a DS0 group on the IAD2435 IAD.

When configuring a DS0 group for a T1/E1 line to a PBX, make sure that the time slot numbers match the channels on the PBX. Contact the PBX administrator to determine which channels to use.

Time slots with identical voice-port configuration can be assigned to one DS0 group.

Time slots with nonidentical voice-port configurations must be assigned to different DS0 groups.

Note The maximum number of time slots available in a T1/E1 is 24. The time slots can be assigned to one DS0 group, or they can be assigned to as many as 24 DS0 groups within the T1/E1.

Step 6 

Repeat Step 3 for each additional DS0 group. After DS0 groups are defined, exit CAS configuration mode.

Configures additional DS0 groups on the T1/E1 interface to the PBX.

Step 7 

voice-port slot/port ds0-group-no

Example:

Router(config)# voice-port 1:D

Enters voice-port configuration mode, and specifies the voice port that you want to configure. The logical slot for these voice ports is the same as for the T1 controller. (See Step 1). The logical port is 0 to 23 for T1 and 0 to 31 for E1, corresponding to the DS0 group.

Step 8 

dial-type {pulse|dtmf}

Example:

Router(config-voice-port)# dial-type dtmf

(FXO only) If this voice port supports rotary pulse dialing, changes the transmit dial type to pulse. The default is dtmf.

Step 9 

compand-type {u-law|a-law}

Example:

Router(config-voice-port)# compand-type a-law

Changes the companding, if necessary. The default is u-law (the North American mu-law ITU-T pulse code modulation (PCM) encoding standard). Specify a-law to use the European a-law ITU-T PCM encoding standard.

Step 10 

no shutdown

Example:

Router(config-voice-port)# no shutdown

Activates the voice port. You should activate only the voice ports that you plan to use.

Step 11 

Exit voice-port configuration mode and repeat Step 5 through Step 8 for the remaining digital voice ports.

Configuring a WIC-1DSU-T1/E1 Serial WAN Interface Card

You can manually configure the synchronous serial interfaces on a WIC-1DSU-T1/E1 serial interface card by entering Cisco IOS commands on the command line. This method, called configuration mode, provides the greatest power and flexibility.


Note Before you begin, disconnect all WAN cables from the Cisco IAD to prevent it from running the AutoInstall process. Whenever you power on the Cisco IAD, if there is a WAN connection on both ends and the Cisco IAD does not have a valid configuration file stored in NVRAM (for instance, when you add a new interface), the Cisco IAD tries to run AutoInstall. It can take several minutes for the Cisco IAD to determine that AutoInstall is not connected to a remote TCP/IP host.


Before you begin configuring the synchronous serial interface, make sure to do the following:

Connect a console to the Cisco IAD.

Power on the Cisco IAD.

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

enable

Example:

Router# enable

Enters privileged EXEC mode.

Step 2 

configure terminal

Example:

Router# configure terminal

Enters global configuration mode.

Step 3 

ip routing

Example:

Router(config)# ip routing

Enables routing protocols as required for your global configuration. This example uses IP routing.

Step 4 

interface type number

Example:

Router(config-controller)# interface serial 0/0

Enters interface configuration mode. You have entered interface configuration mode when the prompt changes to Router(config-if)#.

Step 5 

ip address ip address subnet mask

Example:

Router(config-if)# ip address 172.16.74.1 255.255.255.0

Assigns an IP address and subnet mask to the interface.

Step 6 

half-duplex timer dcd-drop-delay value

Example:

Router(config-if)# half-duplex timer dcd-drop-delay 100

Specifies the time that the interface waits in controlled carrier mode. See Table 3-1 for a list of half-duplex timer commands.

Step 7 

clockrate value

Example:

Router(config-if)# clockrate 7200

To use a port in DCE mode, connect a DCE cable and set the internal transmit clock signal (TXC) speed in bits per second. See Table 3-2, Table 3-3, and Table 3-4 for lists of clock rate settings for specific interfaces. (For ports used in DTE mode, the Cisco IAD automatically uses the external timing signal.)

Step 8 

dce-terminal-timing-enable

Example:

Router(config-if)# dce-terminal-timing-enable

When a port is operating in DCE mode, the default operation is for the DCE to send serial clock transmit (SCT) and serial clock receive (SCR) clock signals to the DTE, and for the DTE to return a serial clock transmit external (SCTE) signal to the DCE.

If the DTE does not return SCTE, enter this command to configure the DCE port to use its own clock signal.

Step 9 

invert-txc

Example:

Router(config-if)# invert-txc

Cisco IADs that use long cables might experience high error rates when operating at higher transmission speeds, because the clock and data signals can shift out of phase.

If a DCE port is reporting a high number of bad packets, inverting the clock by means of this command can often correct the shift.

Step 10 

nrzi-encoding

Example:

Router(config-if)# nrzi-encoding

All serial interfaces support both nonreturn to zero (NRZ) and nonreturn to zero inverted (NRZI) formats. NRZ is the default; NRZI is commonly used with EIA/TIA-232 connections in IBM environments. To enable NRZI encoding on an interface, enter this command.

Step 11 

exit

Example:

Router(config-if)# exit

Exits to global configuration mode.

Repeat Step 4 through Step 12 if your Cisco IAD has more than one serial interface that you need to configure.

Step 12 

Ctrl-z

Example:

Router#

Returns to enable mode when you finish configuring the interfaces.

Configuring a WIC-1T or WIC-2T Serial WAN Interface Card

The WIC-1T or WIC-2T serial interface cards include an integrated DSU/CSU and can be configured either for full T1/E1 service at 1.544 Mb/s or for fractional T1/E1 service. You can configure the interfaces on your T1/E1 WAN interface card manually by entering Cisco IOS commands on the command line. This method, called configuration mode, provides the greatest power and flexibility.


Note Before you begin, disconnect all WAN cables from the Cisco IAD to prevent it from running the AutoInstall process. Whenever you power on the Cisco IAD, if there is a WAN connection on both ends and the Cisco IAD does not have a valid configuration file stored in NVRAM (for instance, when you add a new interface), the Cisco IAD tries to run AutoInstall. It can take several minutes for the Cisco IAD to determine that AutoInstall is not connected to a remote TCP/IP host.



Note The Cisco IAD2435 router is a fixed-configuration router and does not support interface cards.


Before you begin configuring interfaces on a WIC-1T or WIC-2T serial WAN interface card, make sure to do the following:

dsl operating-mode {adsl2[annex a|annex m]|adsl2+ [annex a|annex m]|ansi-dmt|auto|itu-dmt}

Example:

Router(config-if)# dsl operating-mode adsl2+ annex m

Configure the ADSL/SHDSL interface to operate in a specified mode:

ansi-dmt—ANSI full rate mode per T1.413 (ITU G.DMT Issue 1)

auto—Automatic detection mode

itu-dmt—ITU full rate mode (ITU G.DMT Issue 1)

splitterless—G.lite mode per ITU G.992.2


Caution This command is for testing or lab environments only. Using a configuration other than the default configuration for the DSL operating mode can lead to unpredictable behavior on the ADSL/SHDSL line.

Step 11 

no shutdown

Example:

Router(config-if)# no shutdown

Activates the ATM interface.

Step 12 

exit

Example:

Router(config-if)# exit

Exits from ATM interface configuration mode.

Step 13 

exit

Example:

Router(config)# exit

Exits from global configuration mode.

Step 14 

show interface atm slot/port

Example:

Router> show interface atm 1/0

Verifies the ATM interface configuration.

Verifying ATM Configuration

Use the following commands to verify the ATM configuration:

To verify current configuration and to view the status for all controllers, use the show running-config command.

To view ATM controller statistics, use the show controllers atm slot/port command.

To verify the PVC status, use the show atm vc command. Make sure that active PVCs are up.

To help identify ATM-related events as they are generated, use the debug atm events command.

To indicate which interfaces are having trouble, use the debug atm errors command.

To identify an entry for the ATM interface you configured and to show an entry for the ATM slot/port that you configured, use the show ip route command.

To display the configured list of ATM static maps to remote hosts on an ATM network, use the show atm map command.

To view the status of an ATM interface, use the show interface atm slot/port command. Make sure that the ATM slot/port and line protocol are up, as shown in the following example:

Configuring a VIC2-2BRI-NT/TE Card

ISDN BRI VICs provide digital connectivity for VoIP networks using the European Telecommunications Standards Institute (ETSI) Net3 switch type.


Note The Cisco IAD2435 router is a fixed-configuration router and does not support interface cards.


BRI VICs present an ISDN S/T physical interface that connects to a network termination (NT) or terminal equipment (TE) device. With ISDN BRI VICs, you can connect a Cisco IAD2431 or IAD2432 series IAD to a private branch exchange (PBX) network in NT or TE mode or to a public switched telephone network (PSTN) in TE mode.

Each of the two BRI ports can operate in NT mode because the clock source can operate in TE mode as a clock slave.


Note When a VIC port operates in NT mode, it sources a clock to the BRI interface (a PBX trunk card, for example) which is operating in TE mode. When a VIC port operates in TE mode, it receives a clock from the BRI interface (a PBX line card, for example) which is operating in NT mode.


Perform the following steps to configure a VIC2-2BRI-NT/TE card.

Step 3 

no isdn switch-type switch-type

Example:

Router(config)# no isdn switch-type basic-net3

Removes the ISDN switch type.

Step 4 

tdm clock bri-auto

or

tdm clock bri slot/port export

and/or

tdm clock bri slot/port import {t1|e1|atm|bri|onboard}

Example:

Router(config)# tdm clock bri-auto

Configures automatic TDM selection for the BRI VIC.

Configures the BRI port that exports the TDM clock.

Configures the BRI port(s) that import(s) the TDM clock.

Step 5 

interface bri slot/port

Example:

Router(config)# interface bri 0/0

Changes to interface configuration mode for port 0 in slot 0.

Step 6 

no ip address

Example:

Router(config-if)# no ip address

Specifies that there is no IP address for this interface.

Step 7 

shutdown


isdn layer1-emulate {user|network}







no shutdown

Example:

Router(config-if)# shutdown

Router(config-if)# isdn layer1-emulate user

Router(config-if)# no shutdown

Shuts down the interface.

Configures the Layer 1 port mode and clock settings:

Enter user to configure the port as TE and to function as a clock slave. This is the default.

Enter network to configure the port as NT and to function as a clock master.

Activates the interface after the port configuration.

Step 8 

line-power

Example:

Router(config-if)# line-power

(Optional only for NT-configured ports.) Turns on the power supplied from the port to a TE device.

Step 9 

isdn protocol-emulate {user|network}

Example:

Router(config-if)# isdn protocol-emulate user

Configures the Layer 2 port protocol emulation:

Enter user to configure the port as TE so that the PBX is the master. This is the default.

Enter network to configure the port as NT so that the PBX is the slave.

Step 10 

exit

Example:

Router(config-if)# exit

Exits global configuration mode.

Saving Configuration Changes

Perform the following steps to prevent loss of the Cisco IAD configuration.

SUMMARY STEPS

1. enable

2. copy running-config startup-config

3. Ctrl-z

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

enable

Example:

Router# enable
