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.
