Cisco Systems 3825 manual Where, Routerconfig# card type e1 t1 slot subslot

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

Configuration Sequence

Note This configuration assumes that the Cisco 2-port T1/E1-RAN interface card is installed in all three Cisco 2-port T1/E1-RAN interface card slots (physical slots HWIC0, HWIC1, HWIC2, and HWIC3) of the Cisco 3825 router.

Router(config)# card type {e1 t1} slot subslot

Where:

•e1—Card type E1.

•t1—Cart type T1.

•slot—Slot number of the interface.

•subslot—Specifies the Cisco 2-port T1/E1-RAN interface card (serial slot) port number.

For example, there is no Cisco 2-port T1/E1-RAN interface card located in the Cisco 3825 router serial slot 0 (physical slot HWIC0). So, the interface card is located in physical slot HWIC1. As a result, the following command configures the Cisco 2-port T1/E1-RAN interface card located in the Cisco 3825 router serial slot 0 (physical slot HWIC1), first port of the Cisco 2-port T1/E1-RAN interface card as a E1:

Router(config)# card type e1 0 1

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 interface numbering shifts. The configuration that you created for logical 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 the serial slot the 2-port T1/E1-RAN card is located in the Cisco 3825 router.

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

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