Chapter 20 POS on ONS Ethernet Cards
POS Interoperability
The CRC size option does not need to match on the two endpoints when using GFP-F framing mode.
All Ethernet cards do not interoperate or support all the POS port characteristic options. The following
two tables list the interoperable Ethernet cards and characteristics. Table 20-1 lists this information for
cards supporting and configured with high-level data link control (HDLC) framing mode.
Table 20-2 lists this information for cards supporting and configured with frame-mapped generic
framing procedure (GFP-F) framing mode. With Table 20- 2 and GFP-F framing, the word LEX is used
to represent standard mapped Ethernet over GFP-F according to ITU-T G.7041. Under GFP-F framing,
the Cisco IOS CLI also uses this lex keyword to represent standard mapped Ethe rnet over GFP-F
according to ITU-T G.7041.
