SPX Port Combinations

Speeds on each end of an SPX link must match. The following tables provide valid SPX port combinations.

Note: If you have potential PE units connected downstream over 1-Gbps links to be converted to 10-Gbps SPX links, refer to Converting 1-Gbps SPX PE links to 10-Gbps links.
Note: 1-Gbps connections between CB units and PE units are supported beginning from FastIron release 08.0.80.
