Chapter 5 Configuring POS on the ML-Series Card

Configuring the POS Interface

	Command	Purpose
Step 3
Step 3	Router(config-if)# [no] pos mode gfp	Sets the framing mode employed by the ONS
	[fcs-disabled]	Ethernet card for framing and encapsulating data
		packets onto the SONET transport layer. Valid
		framing modes are:
		• HDLC—A common mechanism employed in
		framing data packets for SONET. HDLC is
		not a keyword choice in the command. The no
		form of the command sets the framing mode
		to Cisco HDLC.
		• GFP (default)—The ML-Series card supports
		the frame mapped version of generic framing
		procedure (GFP-F).
		GFP-F with a 32-bit CRC, also referred to as
		frame check sequence (FCS), is enabled by
		default. The optional FCS-disabled keyword
		disables the GFP-F 32-bit FCS.
		The FCS-disabled keyword is not available when
		setting the framing mode to Cisco HDLC.
		Note CRC-under-HDLC framing is restricted to
		a 32-bit size and cannot be disabled.
		Note The GFP-F FCS is compliant with ITU-T
		G.7041/Y.1303
Step 4
Step 4	Router(config-if)# no shutdown	Restarts the shutdown interface.
Step 5
Step 5	Router(config)# end	Returns to privileged EXEC mode.
Step 6
Step 6	Router# copy running-config startup-config	(Optional) Saves configuration changes to
		NVRAM.

Configuring POS Interface Encapsulation Type Under GFP-F Framing

To configure the encapsulation type for a ML-Series card, perform the following steps beginning in global configuration mode:

	Command	Purpose
Step 1
Step 1	Router(config)# interface pos number	Activates interface configuration mode to
		configure the POS interface.
Step 2
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).
