Cisco VIP-4R/4T Installation And Configuration Manual page 65

The show version (or show hardware) command displays the configuration of the system hardware
(the number of each interface processor type installed), the software version, the names and sources
of configuration files, and the boot images. Following is an example of the show version command
used with a Cisco 7500 series system:
Router# show version

Configuring Timing (Clock) Signals
All interfaces support both DTE and DCE mode, depending on the mode of the interface cable
attached to the port. To use a port as a DTE interface, you need only connect a DTE adapter cable to
the port. When the system detects the DTE mode cable, it automatically uses the external timing
signal. To use a port in DCE mode, you must connect a DCE interface cable and set the clock speed
with the clockrate configuration command. You must also set the clock rate to perform a loopback
test. This section describes how to set the clock rate on a DCE port and, if necessary, how to invert
the clock to correct a phase shift between the data and clock signals.
Setting the Clock Rate
All DCE interfaces require a noninverted internal transmit clock signal, which is generated by the
4T port adapter. The default operation on an 4T port adapter DCE interface is for the DCE device
(4T port adapter) to generate its own clock signal (TxC) and send it to the remote DTE. The remote
DTE device returns the clock signal to the DCE (4T port adapter interface). The clockrate command
specifies the rate as a bits-per-second value. In the following example, the clock rate for the serial
interface on a 4T port adapter on a VIP in interface processor slot 3 (3/1/0) is defined as 72 kbps:
Router(config)# interface serial 3/1/0
Router(config-int)# clockrate 72000
Use the no clockrate command to remove the clock rate.
