Version Description
9.2(0.0) Introduced on the M I/O Aggregator.
8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information Splitting a 40G port into 4x10G port is supported on standalone and stacked units.
• You cannot use split ports as stack-link to stack an MXL Switch.
• The split ports MXL switch unit cannot be a part of any stacked system.
• The unit number with the split ports must be the default (stack-unit 0).
• This set up can be veried using show system brief command. If the unit ID is dierent than 0, it must be
renumbered to 0 before ports are split by using the stackunit id renumber 0 command in EXEC mode.
The quad port must be in a default conguration before it can be split into 4x10G ports. The 40G port is lost in the
cong when the port is split, so be sure that the port is also removed from other L2/L3 feature congurations.
The system must be reloaded after issuing the CLI for the change to take eect.

Version Description
9.10(0.0) Introduced on the S6000, S6000–ON, S5000, S4810, S4820T, S3048–ON, S4048–ON,
M I/O Aggregator, FN I/O Module, MXL, C9010, S3100 series, and Z9100-ON.
Usage Information
The wavelength can be congured only on a tunable 10–Gigabit SFP+ optic. The wavelength range is from 1528.3
nm to 1568.77nm.
If you congure the wavelength on a non-tunable optic, there is no change to the existing wavelength. The
congured wavelength is saved in the running conguration and is applicable, when a tunable optic is used.
If you do not congure the wavelength on an inserted tunable optic, the existing wavelength is used.
Example
The following example shows the wavelength set for a tunable 10–Gigabit SFP+ optic:
