Modifying the POS Framing
Command
Router(config-if)# pos framing {sonet | sdh}
To return to the default, use the no form of the command.
Verifying the POS Framing
To verify the POS framing, use the show controllers pos privileged EXEC command and observe the value
shown in the "Framing" field. The following example shows that POS framing mode is set to SONET for the
first interface (0) on the POS SPA installed in subslot 2 of a SIP installed in chassis slot 3:
Router# show controllers pos 3/2/0

Purpose
Specifies the POS framing type, where:
• sonet—Enables Synchronous Optical Network
framing for optical carrier (OC) rates. This is
the default.
• sdh—Enables Synchronous Digital Hierarchy
framing for synchronous transfer mode (STM)
rates.
The POS framing type must be configured to be the
same on both ends of the POS link.
