SFP+ port
The LSWM124XG2Q, LSWM124XG2QFC, and LSWM124XG2QL interface modules each provide
24 SFP+ ports. The SFP+ ports support the following transceiver modules and cables:
• 10-GE SFP+ transceiver modules in Table 30.
• 10-GE SFP
+ copper cables in Table 31.
• 10-GE SFP
+ fiber cables in Table 32.
• GE SFP
transceiver modules in Table 17.
NOTE:
When a GE SFP module is installed in an SFP+ port on the LSWM124XG2QL interface card, the
SFP+ port does not support rate and duplex autonegotiation. You must configure the speed 1000
and duplex full commands on both ends.
