Chapter 4 Configuring the Cisco 3825 Mobile Wireless Edge Router in a RAN-O Solution with the Command-Line
Configuration Sequence
For example, the following command overwrites the number 16 for the packet of traffic for the umts-iub
interface:
Router(config-if)# umts-iub set peering dscp 16
Step 20 To configure the local parameters required to establish an IP/UDP backhaul connection, enter the
following command including the IP address and port you want to establish the IP/UDP backhaul
connection from.
Router(config-if)# umts-iub local
ip-address port
For example, the following command configures the umts-iub local interface with an IP address and port
of 20.20.20.21 6666:
Router(config-if)# umts-iub local 20.20.20.21 6666
Step 21 To configure the remote parameters required to establish an IP/UDP backhaul connection, enter the
following command including the IP address and port you want to establish the IP/UDP backhaul
connection from.
Router(config-if)# umts-iub remote
ip-address port
For example, the following command configures the umts-iub remote interface with an IP address and
port of 20.20.20.20 6666:
Router(config-if)# umts-iub local 20.20.20.20 6666
Step 22 Exit the interface configuration mode.
Router(config-if)# exit
Configuring Satellite Support
To support the configuration of a network when satellites are employed, you must implement a
configurable jitter buffer and a tunable retransmission timer of repetitive sub-rates to overcome the
network latency and satellite signal fade.
Use the following instructions to perform a GSM-Abis configuration with satellite support on the
Cisco 2-port T1/E1-RAN interface card located in the Cisco 3825 router by entering the following Cisco
IOS commands at the router prompt.
You might also need to enter other configuration commands, depending on the requir ements for your
system configuration and the protocols you plan to route on the i nterface.
Note In the following procedure, press the Return key after each step unless otherwise noted. At any time,
you can exit the privileged level and return to the user level by entering disable at the Router# prompt.
To configure the GSM-Abis attributes with satellite support, follow these steps while in the global
configuration mode:
Step 1 Perform Steps 1 through 10 as described in the previous procedure (see the “Configuring GSM-Abis
Links” procedure on page 4-20).
