Command History
Usage Guidelines Use this command to provide clocking for the client signal for specific protocols. The protocol
encapsulation must be configured for the transparent interface to allow signal monitoring to be enabled
with the monitor enable command. The following protocol encapsulation types are supported in 3R
mode plus protocol monitoring:
• ESCON
• Fibre Channel (1 Gbps only)
• FICON
• Gigabit Ethernet
• ISC compatibility mode
• SDH
• SONET
The following protocol encapsulation types are supported in 3R mode without protocol monitoring:
• Fast Ethernet
• FDDI
• Fibre Channel (2 Gbps)
• ISC peer mode
• Sysplex CLO (control link oscillator)
• Sysplex ETR (external timer reference)
To specify the signal clock rate without specifying a protocol, use the clock rate command.
Sysplex CLO and Sysplex ETR are supported outside the nominal range of the clock rates for the
Cisco ONS 15530 because of the nature of the traffic type.
Note Encapsulation cannot be changed without first disabling monitoring using the no monitor enable
command.
Removing the encapsulation on a transparent interface with the no encapsulation command does not
turn off the laser. To turn off the transmit laser to the client equipment, use the shutdown command.
Examples The following example shows how to configure SONET encapsulation at a rate of OC-3 on a transparent
interface.
Switch# configure terminal
Switch(config)# interface transparent 2/0/0
Switch(config-if)# encapsulation sonet oc3
