Usage
Information
If an IP address or VRRP group is assigned to the interface, you cannot use the switchport command
on the interface. To use the switchport command on an interface, only the no ip address and no
shutdown statements must be listed in the show config output.
When you enter the switchport command, the interface is automatically added to the default VLAN.
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
EMC Networking OS Configuration Guide.

Version Description
9.10(0.1) Introduced on the S6010-ON and S4048T-ON.
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:
