Users Guide

To use the switchport backup interface command on a port, first enter the switchport
command. For more information, see “Configuring Redundant Links” in the Layer 2 section in the Dell
Networking OS Configuration Guide.

History
This guide is platform-specific. 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 configured only on a tunable 10–Gigabit SFP+ optic. The wavelength range is
from 1528.3 nm to 1568.77nm.
If you configure the wavelength on a non-tunable optic, there is no change to the existing wavelength.
The configured wavelength is saved in the running configuration and is applicable, when a tunable optic is
used.
If you do not configure 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 configure 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 configuring and using Port Channels, refer
to the Dell Networking OS Configuration Guide.
