The module has four 1-Gigabit SFP module slots. Any combination of standard
SFP modules is supported. SFP+ modules are not supported.

If you insert an SFP+ module in the 1-Gigabit network module, the SFP+ module
does not work, and the switch logs an error message.

The module has four slots. Two slots support only 1-Gigabit SFP modules. Two
slots support either 1-Gigabit SFP or 10-Gigabit SFP+ modules.
slots support either 1-Gigabit SFP or 10-Gigabit SFP+ modules.
Note
The GLC-T SFP is not supported on the SFP+ slots of C3KX-NM-10G.
The four slots are grouped as two pairs, with each pair consisting of one SFP slot
and one SFP+ slot. Each pair supports either two 1-Gigabit SFP modules or one
10-Gigabit SFP+ module. A 10-Gigabit SFP+ module cannot operate at the same
time as the corresponding 1-Gigabit SFP module in the pair.
and one SFP+ slot. Each pair supports either two 1-Gigabit SFP modules or one
10-Gigabit SFP+ module. A 10-Gigabit SFP+ module cannot operate at the same
time as the corresponding 1-Gigabit SFP module in the pair.
Supported combinations of SFP and SFP+ modules:
•
Slots 1, 2, 3, and 4 with 1-Gigabit SFP modules
•
Slots 1 and 2 with 1-Gigabit SFP modules and Slot 4 with one 10-Gigabit
SFP+ module

Slot 2 with one 10-Gigabit SFP+ module and Slots 3 and 4 with 1-Gigabit

Slot 2 and Slot 4 each with 10-Gigabit SFP+ modules
A 10-Gigabit SFP+ module takes precedence over a 1-Gigabit SFP module except
when an SFP module is first inserted in Slot 1 and has link. When you insert an
SFP+ module in Slot 2, the SFP in Slot 1 retains link. The SFP+ module in Slot
2 does not operate.
when an SFP module is first inserted in Slot 1 and has link. When you insert an
SFP+ module in Slot 2, the SFP in Slot 1 retains link. The SFP+ module in Slot
2 does not operate.
When the SFP module in Slot 1 is shutdown, loses link, or is removed, the SFP+
module in Slot 2 turns on. The SFP module in Slot 1 does not work as long as an
SFP+ module is in Slot 2, whether it has link up or not.

The same precedence applies to Slots 3 and 4.
