The default encapsulation for the ML-Series card is LEX and the corresponding default MTU is
1500 bytes. When connecting to an external POS device, it is important to ensure that both the
ML-Series switch and the external device uses the same configuration for the parameters listed in
Table 5-6 .
ML-Series Card to G-Series Card
Figure 5-3 illustrates a POS configuration between an ML-Series card and a G-Series card.

Command Parameter
Router(config-if)# encapsulation ppp
or
Router(config-if)# encapsulation hdlc
Encapsulation—Default encapsulation on the Cisco
12000 GSR Series is HDLC, which is supported by the
ML-Series. PPP is also supported by both the ML-Series
card and the Cisco 12000 GSR Series.
The Cisco 12000 GSR Series does not support LEX,
which is the default encapsulation on the ML-Series
card.
Router(config-if)# show controller
pos
C2 Byte—Use the show controller pos command to
verify that the transmit and receive C2 values are the
same.
Router(config-if)# pos flag c2 value Sets the C2 byte value. Valid choices are 0 to 255
(decimal). The default value is 0x01 (hex) for LEX.
