– PPP authentication type: CHAP or PAP
– PPP client name to access the router
– PPP password to access the router
- If you are setting up IP routing:
– Generate the addressing scheme for your IP network.
- If you are setting up the serial interface:
– Mode of operation (sync, async, bisync)
– Clock rate depending on the mode
– IP address depending on the mode
- If you are setting up 3G:

Configuring the Cellular Wireless WAN Interface
The Cisco 819 ISRs provide a Third-Generation (3G) wireless interface for use over Global System for Mobile Communications (GSM) and code division multiple access (CDMA) networks. The interface is a 34-millimetre embedded mini express card.
Its primary application is WAN connectivity as a backup data link for critical data applications. However, the 3G wireless interface can also function as the router’s primary WAN connection.
To configure the 3G cellular wireless interface, follow these guidelines and procedures:
Prerequisites for Configuring the 3G Wireless Interface
The following are prerequisites to configuring the 3G wireless interface:
- You must have wireless service from a carrier, and you must have network coverage where your router will be physically placed. For a complete list of supported carriers, see the data sheet at:
www.cisco.com/go/m2m
– Username
– Password
– Access point name (APN)
- To configure your CDMA (CDMA only) data profile for manual activation, you need the following information from your service provider:
– Master Subsidy Lock (MSL) number
– Mobile Directory number (MDN)
– Mobile Station Identifier (MSID)
– Electronic Serial Number (ESN)
- Check the LED located on the front panel of the router for signal strength and other indications. Table 2-1 describes the 3G LEDs for the Cisco 819 ISR.
Restrictions for Configuring the Cellular Wireless Interface
The following restrictions apply to configuring the Cisco 3G wireless interface:
- A data connection can be originated only by the 3G wireless interface. Remote dial-in is not supported.
- Because of the shared nature of wireless communications, the experienced throughput varies depending on the number of active users or the amount of congestion in a given network.
- Cellular networks have higher latency than wired networks. Latency rates depend on the technology and carrier. Latency may be higher when there is network congestion.
- VoIP is currently not supported.
- Any restrictions that are part of the terms of service from your carrier also apply to the Cisco 3G wireless interface.
- Inserting a different type of modem from what was previously removed requires configuration changes and you must reload the system.
Data Account Provisioning
Note To provision your modem, you must have an active wireless account with a service provider. A SIM card must be installed in a GSM 3G wireless card.
To provision your data account, follow these procedures:

Configuring Dual SIM for Cellular Networks
The Dual SIM feature implements auto-switch and failover between two cellular networks on a Cisco 819 ISR. This feature is enabled by default with SIM slot 0 being the primary slot and slot 1 being the secondary (failover) slot.
Note For instructions on how to configure the Dual SIM feature for 4G LTE cellular networks, see the Cisco 4G LTE Software Installation Guide.
You can configure the Dual SIM feature using the following commands:
|
|
|
gsm failovertimer |
gsm failovertimer <1-7> |
Sets the failover timer in minutes. |
gsm sim authenticate |
gsm sim authenticate <0,7> <pin> slot <0-1> |
Verifies the SIM CHV1 code. |
gsm sim max-retry |
gsm sim max-retry <0-65535> |
Specifies the maximum number of failover retries. The default value is 10. |
gsm sim primary slot |
gsm sim primary slot <0-1> |
Modifies the primary slot assignment. |
gsm sim profile |
gsm sim profile <1-16> slot <0-1> |
Configures the SIM profile. |
Note the following:
- For auto-switch and failover to work, configure the SIM profile for slots 0 and 1 using the gsm sim profile command.
- For auto-switch and failover to work, configure the chat script without a specific profile number.
- If no SIM profile is configured, profile #1 is used by default.
- If no GSM failover timer is configured, the default failover timeout is 2 minutes.
- If no GSM SIM primary slot is configured, the default primary SIM is slot 0.
The following example shows you how to set the SIM switchover timeout period to 3 minutes:
router(config-controller)# gsm failovertimer 3
The following example shows you how to authenticate using an unencrypted pin:
router(config-controller)# gsm sim authenticate 0 1234 slot 0
The following example shows you how to set the maximum number of SIM switchover retries to 20:
router(config-controller)# gsm sim max-retry 20
The following example shows you how to set SIM slot 1 as the primary slot:
router(config-controller)# gsm sim primary slot 1
The following example shows you how to configure the SIM card in slot 0 to use profile 10:
router(config-controller)# gsm sim profile 10 slot 0
Perform the following commands to manually switch the SIM:
|
|
|
cellular GSM SIM |
cellular GSM SIM {lock | unlock} |
Locks or unlocks the SIM. |
gsm sim |
cellular <unit> gsm sim [lock | unlock] <pin> |
Locks or unlocks the gsm SIM. |
gsm sim unblock |
cellular <unit> gsm sim unblock <puk> <newpin> |
Unblocks the gsm SIM. |
gsm sim change-pin |
cellular <unit> gsm sim change-pin <oldpin> <newpin> |
Changes the PIN of the SIM. |
gsm sim activate slot |
cellular <unit> gsm sim activate slot <slot_no> |
Activates the GSM SIM. |
The following command forces the modem to connect to SIM1:
Router# cellular 0 gsm sim activate slot 1
Configuring Router for Image and Config Recovery Using Push Button
A push button feature is available on the Cisco 819 ISR. The reset button on the front panel of the router enables this feature.
Perform the following steps to use this feature:
Step 1 Unplug power.
Step 2 Press the reset button on the front panel of the router.
Step 3 Power up the sytem while holding down the reset button.
The system LED blinks four times indicating that the router has accepted the button push.
Using this button takes effect only during ROMMON initialization. During a warm reboot, pressing this button has no impact on performance. Table 5-4 shows the high level functionality when the button is pushed during ROMMON initialization.
Table 5-4 Push Button Functionality during ROMMON Initialization
|
|
- Boots using default baud rate.
- Performs auto-boot.
- Loads the *.default image if available on compact flash
Note If no *.default image is available, the ROMMON will boot up with the first Cisco IOS image on flash. Examples of names for default images: c800-universalk9-mz.SPA.default, c-800-universalk9_npe-mz.151T.default, image.default Note You can only have one configuration file with *.cfg option. Having more than one file will result in uncertain operational behavior. |
If the configuration named *.cfg is available in nvram storage or flash storage, IOS will perform a backup of the original configuration and will boot up using this configuration. |
Use the show platform command to display the current bootup mode for the router. The following sections show sample outputs when the button is not pushed and when the button is pushed.
Output When Button Is Not Pushed: Example
router# show platform boot-record
Platform Config Boot Record :
============================
Configuration Register at boot time : 0x0
Reset Button Status at Boot Time : Not Pressed
Startup-config Backup Status at Boot: No Status
Startup-config(backup file)location : No Backup
Golden config file at location : No Recovery Detected
Config Recovery Status : No Status
Output When Button Is Pushed: Example
router# show platform boot-record
Platform Config Boot Record :
============================
Configuration Register at boot time : 0x0
Reset Button Status at Boot Time : Pressed
Startup-config Backup Status at Boot: Ok
Startup-config(backup file)location : flash:/startup.backup.19000716-225840-UTC
Golden config file at location : flash:/golden.cfg
Config Recovery Status : Ok
Push Button in WLAN AP
When the push button on the front panel is pressed, WLAN AP will perform both image and configuration recovery.
To perform image recovery, WLAN will go into the boot loader so that the user can download the image from the bootloader prompt.
To perform configuration recovery, WLAN AP will overwrite the contents of flash:/config.txt with the contents of flash:/cpconfig-ap802.cfg file if available in flash drive. Otherwise, flash:/config.txt will be deleted.
Configuring the Fast Ethernet LAN Interfaces
The Fast Ethernet LAN interfaces on your router are automatically configured as part of the default VLAN and are not configured with individual addresses. Access is provided through the VLAN. You may assign the interfaces to other VLANs if you want. For more information about creating VLANs, see the “Configuring the Ethernet Switches” section.
Configuring Dynamic Routes
In dynamic routing, the network protocol adjusts the path automatically, based on network traffic or topology. Changes in dynamic routes are shared with other routers in the network.
The Cisco routers can use IP routing protocols, such as Routing Information Protocol (RIP) or Enhanced Interior Gateway Routing Protocol (EIGRP), to learn routes dynamically. You can configure either of these routing protocols on your router.
Configuring Routing Information Protocol
To configure the RIP routing protocol on the router, perform these steps, beginning in global configuration mode:
SUMMARY STEPS
1. router rip
2. version {1 | 2}
3. network ip-address
4. no auto-summary
5. end
DETAILED STEPS
|
|
|
Step 1 |
router rip Example:
Router> configure terminal
Router(config)# router rip
|
Enters router configuration mode and enables RIP on the router. |
Step 2 |
version { 1 | 2 } Example:
Router(config-router)# version 2
|
Specifies use of RIP version 1 or 2. |
Step 3 |
network ip-address Example:
Router(config-router)# network 192.168.1.1
Router(config-router)# network 10.10.7.1
|
Specifies a list of networks on which RIP is to be applied, using the address of the network of each directly connected network. |
Step 4 |
no auto-summary Example:
Router(config-router)# no auto-summary
|
Disables automatic summarization of subnet routes into network-level routes. This allows subprefix routing information to pass across classfull network boundaries. |
Step 5 |
end Example:
Router(config-router)# end
|
Exits router configuration mode and enters privileged EXEC mode. |
For general information on RIP, see the “RIP” section.
Example
The following configuration example shows RIP version 2 enabled in IP network 10.0.0.0 and 192.168.1.0.
To see this configuration, use the show running-config command from privileged EXEC mode.
Router# show running-config
Verifying Configuration
To verify that you have properly configured RIP, enter the show ip route command and look for RIP routes signified by “R.” You should see a verification output like the following example:
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route
Gateway of last resort is not set
10.0.0.0/24 is subnetted, 1 subnets
C 10.108.1.0 is directly connected, Loopback0
R 3.0.0.0/8 [120/1] via 2.2.2.1, 00:00:02, Ethernet0/0
Configuring Enhanced Interior Gateway Routing Protocol
To configure Enhanced Interior Gateway Routing Protocol (EIGRP), perform these steps, beginning in global configuration mode:
SUMMARY STEPS
1. router eigrp as-number
2. network ip-address
3. end
DETAILED STEPS
|
|
|
Step 1 |
router eigrp as-number Example:
Router(config)# router eigrp 109
|
Enters router configuration mode and enables EIGRP on the router. The autonomous-system number identifies the route to other EIGRP routers and is used to tag the EIGRP information. |
Step 2 |
network ip-address Example:
Router(config)# network 192.145.1.0
Router(config)# network 10.10.12.115
|
Specifies a list of networks on which EIGRP is to be applied, using the IP address of the network of directly connected networks. |
Step 3 |
end Example:
Router(config-router)# end
|

The following configuration example shows the EIGRP routing protocol enabled in IP networks 192.145.1.0 and 10.10.12.115. The EIGRP autonomous system number is 109.
To see this configuration, use the show running-config command, beginning in privileged EXEC mode.
Verifying Configuration
To verify that you have properly configured IP EIGRP, enter the show ip route command and look for EIGRP routes indicated by “D.” You should see a verification output similar to the following:
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route
Gateway of last resort is not set
10.0.0.0/24 is subnetted, 1 subnets
C 10.108.1.0 is directly connected, Loopback0
D 3.0.0.0/8 [90/409600] via 2.2.2.1, 00:00:02, Ethernet0/0
