Chapter 4 Configuring the Cisco 3825 Mobile Wireless Edge Router in a RAN-O Solution with the Command-Line
Configuration Sequence
Step 17 Continue to configure HSRP to track Multilink1 and Loopback103 if needed.
Step 18 Specify a priority of 100.
Router(config-if)# standby group priority 100
Note If you are using the Cisco 3825 in a redundant configuration, you must also set the keepalives under the
GE interface to 1.
Router(config-if)# keepalive 1
Standalone Cisco 3825 Router
The Cisco 3825 router has relays that work with a special y-cable for redundancy and that are controlled
by HSRP. You can, however, use the Cisco 3825 as a standalone device. If you choose not to use the
Cisco 3825 in a redundant configuration, you should not configure HSRP and you must manually control
the relays of the Cisco 2-port T1/E1-RAN card.
To manually set the relays to open or closed, follow these steps, while in the global configuration mode:
Step 1 To go to the redundancy mode, enter redundancy mode:
Router(config)# redundancy
Step 2 In the redundancy mode, enter the y-cable mode:
Router(config-r)# mode y-cable
Step 3 Specify that the router is to be used as a standalone device. This command closes the relays.
Router(config-r-y)# standalone
Step 4 Exit y-cable configuration mode.
Router(config-r-y)# exit
To verify the status of the relays on an Cisco 3825 router, use the show controllers command.
Configuring for SNMP Support
Use the following instructions to configure for Simple Network Management Protocol (SNMP) support:
setting up the community access, establishing a message queue for each trap host, enabling the router to
send SNMP traps, enabling SNMP traps for alarms, and enabling SNMP traps for a specific environment.
You might also need to enter other configuration commands, depending on the requirements for your
system configuration and the protocols you plan to route on the interface.
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.
