VIP2 and the 4R Port Adapter
Router>
Use the following procedure to perform a basic configuration:
Step 1 After you access the privileged level of the EXEC as described in the section “Using the EXEC Command Interpreter” on page 20, enter the configure command:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Step 2 Specify the first Token Ring interface to configure by entering the subcommand interface type slot/port adapter/interface. For example, if you are configuring Token Ring interface 0 for a 4R port adapter installed in port adapter slot 0, on a VIP2 installed in chassis slot 3, enter the following command:
Router(config)# interface tokenring 3/0/0
Step 3 If IP routing is enabled on the system, you can assign an IP address and subnet mask to the interface with the ip address configuration subcommand as follows:
Caution Each Token Ring port must be configured for the same ring speed as the ring to which it is connected; either 4 or 16 Mbps. If the port is set for a different speed, it will cause the ring to beacon, which effectively brings the ring down and makes it inoperable.
Note Token Ring ports operate at either 4 or 16 Mbps. The default speed for the 4R port adapter’s Token Ring ports is 4 Mbps, which you can change to 16 Mbps on any port using the configuration
Step 4 Change the default shutdown state and enable the interface:
When you enable the interface by using the no shutdown command, the LED for 4 Mbps or 16 Mbps is turned on after about 5 seconds. The In Ring LED for that interface is turned on about 5 to 18 seconds later, when the port is initialized and connected to the ring.
Step 5 Either accept the default ring speed of 4 Mbps, or enable the Token Ring interface speed for
Step 6 Enter any additional configuration subcommands required.
Step 7 Repeat Steps 2 through 6 for each new interface.
Step 8 When all new interfaces are configured, press
Router# copy
[OK]
Router#
Step 10 Enter quit to exit configuration mode:
Router# quit
