Chapter 5 Configuring POS on the ML-Series Card
Configuring the POS Interface
Scrambling on the ONS 15310-CL and ONS 15310-MA ML-Series card is on by default and is not
configurable. The C2 byte is not configurable. CRC-under-HDLC framing is restricted to 32-bit and is
not configurable. CRC-under-GFP-F is restricted to 32-bit, but can be enabled (default) and disabled.
Note ML-Series card POS interfaces normally send PDI-P to the far end when the POS link goes down or RPR
wraps. ML-Series card POS interfaces do not send PDI-P to the far end when PDI-P is detected, when
RDI-P is being sent to the far end, or when the only defects detected are GFP LFD, GFP CSF,
V C AT L O M , or VC AT SQ M .
Configuring POS Interface Framing Mode
You can configure framing mode on an ML-100T-8 card through Cisco IOS. You cannot configure
framing mode through CTC on the ML-100T-8 card.
Framing mode can be changed on a port by port basis. The user does not need to delete the existing
circuits or reboot the ML-100T-8 card. On the ONS 15454 or ONS 15454 SDH ML-Series cards, the
circuits must be deleted and the card must reboot for the framing mode to change.
To configure framing mode for the ML-Series card, perform the following steps, beginning in global
configuration mode:
Command Purpose
Step 1
Router(config)# interface pos
number
Activates interface configuration mode to
configure the POS interface.
Step 2
Router(config-if)# shutdown
Manually shuts down the interface. Encapsulation
and framing mode changes on POS ports are
allowed only when the interface is shut down
(ADMIN_DOWN).
