Cisco Systems 3825 manual Routerconfig# controller e1 0/2/0, Routerconfig-controller# mode atm aim

Chapter 4 Configuring the Cisco 3825 Mobile Wireless Edge Router in a RAN-O Solution with the Command-Line

Configuration Sequence

When the command is used for the first time, the configuration takes effect immediately. A subsequent change in the card type will not take effect unless you enter the reload command or reboot the router

Step 2 Specify the controller that you want to configure by entering the controller configuration mode. Controller E1 0/0/0 maps to the first port of the Cisco 2-port T1/E1-RAN interface card located in the Cisco 3825 router serial slot 0 (physical slot HWIC0). Controller E1 0/0/1 maps to the second port of the Cisco 2-port T1/E1-RAN interface card located in the Cisco 3825 router serial slot 0 (physical slot HWIC0).

Note If you install a Cisco 2-port T1/E1-RAN interface card in the Cisco 3825 router in physical slot HWIC1 (leaving physical slot HWIC0 empty), the logical interfaces in physical slot HWIC1 become Serial 0/0/0 and Serial 0/0/1. If you later add a Cisco 2-port T1/E1-RAN interface card to physical slot HWIC0, the logical interface numbering shifts. The configuration that you created for interfaces Serial 0/0/0 and Serial 0/0/1 will now be applied to the

Cisco 2-port T1/E1-RAN interface card in physical slot HWIC0, and you will need to create a new configuration for the logical interfaces that you previously configured on HWIC1 (which will now be Serial 0/1/0 and Serial 0/1/1). For more information about interface numbering, see Understanding the Cisco 3825 Router Interface Numbering, page 3-1.

Router(config)# controller e1 slot/subslot/port

Where:

•slot—Number of serial slot the Cisco 2-port T1/E1-RAN interface card located in the Cisco 3825 router.

•subslot—Number of serial subslot the Cisco 2-port T1/E1-RAN interface card located in the Cisco 3825 router.

•port—Number of the serial port the Cisco 2-Port T1/E1-RAN interface card is using.

With a Cisco 2-port T1/E1-RAN interface card located in the Cisco 3825 router slot 0 (physical slot HWIC0), for example, the following command specifies the E1 controller as the first port of the Cisco 2-port T1/E1-RAN interface card located in the Cisco 3825 router serial slot 0 (physical slot HWIC0):

Router(config)# controller e1 0/2/0

Router(config-controller)#

Step 3 Configure the AIM for ATM card to be used for ATM traffic on the previously specified E1 controller.

Router(config-controller)# mode atm aim aim-slot

Where aim-slotsets the mode of the E1 controller in the AIM slot.

For example, the following command sets the mode of the E1 controller in AIM slot 1:

Router(config-controller)# mode atm aim 1

Step 4 Enter the clocking source.

Router(config-controller)#clock source {line [primary] internal}

Where:

•line—Specifies the E1 line from which the clocking is taken.

•internal—Specifies internal clocking.

•primary—Primary clock source.
