Command History
This guide is platform-specic. For command information about other platforms, see the relevant Dell Networking
OS Command Line Reference Guide.
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:
Dell(conf-if-te-1/1/1)# wavelength 1528.30

Port Channel Commands
A Link Aggregation Group (LAG) is a group of links that appear to a MAC client as if they were a single link according to IEEE 802.3ad. In
Dell Networking OS, a LAG is referred to as a Port Channel.
• The platform supports 4096 port channels and 16 members per port channel.
As each port can be assigned to only one Port Channel, and each Port Channel must have at least one port, some of those nominally
available Port Channels might have no function because they could have no members if there are not enough ports installed. But stack
members can provide those ports.
NOTE
: The Dell Networking OS implementation of LAG or Port Channel requires that you congure a LAG on both switches
manually. For information about Dell Networking OS link aggregation control protocol (LACP) for dynamic LAGs, refer to the Link
Aggregation Control Protocol (LACP) chapter. For more information about conguring and using Port Channels, refer to the Dell
Networking OS Conguration Guide .
