Table 4-1 lists the half-duplex timer commands.
The following clock rate settings are for two-port asynchronous/synchronous
serial WICs:
• 1200 bps
• 2400 bps
• 4800 bps
• 9600 bps
Step 10
Exit back to global configuration mode.
If your Catalyst 4224 has more that one serial interface that
you need to configure, repeat Step 4 through Step 9.
gateway(config-if)# exit
Step 11
When you finish configuring the interface, return to enable
mode.
gateway(config)# Ctrl-z
