PA-4R Half-Duplex Token Ring Port Adapter Installation and Configuration
OL-3589-01
Cisco 7200 Series and the 4R Port Adapter
With the show interfaces type slot/port command, use arguments such as the interface type (Token Ring,
and so forth) slot, and the port number (slot/port) to display information about a specific Token Ring
interface only.
The following example of the show interfaces tokenring slot/port command shows all of the
information specific to the first 4R interface port (interface port 0) in port adapter slot 6:
Router# sh int tokenring 6/0
TokenRing6/0 is administratively down, line protocol is down

To determine which type of port adapter is installed on a Cisco 7206 in your system, use the show
diag slot command. Specific port adapter information is displayed, as shown in the following example
of a 4R port adapter in port adapter slot 6:
Router# show diag 6
Slot 6:
Token-ring port adapter, 4 ports
Port adapter is analyzed

Using the ping Command
The ping command allows you to verify that an interface port is functioning properly and to check the
path between a specific port and connected devices at various locations on the network. This section
provides brief descriptions of the ping command. After you verify that the system has booted
successfully and is operational, you can use this command to verify the status of interface ports. Refer
to the publications listed in the section “If You Need More Information” on page 2, for detailed
command descriptions and examples.
