Optional Modules
S3100 series supports an optional small form-factor pluggable plus (SFP+) or 10GBase-T module.
In S3100 series, the hot swap of optional modules is supported with the following behavior:
• If you change the same type of optional module, then the old configuration is retained.
• If you change a different type of optional module, then the optional module is moved into error state.
• You can modify the configuration of optional module interfaces, only if the optional module is present.
• After removing the optional module, you need to wait for the syslogs to be removed before inserting the
optional module again. You cannot insert the module immediately.
View Basic Interface Information
To view basic interface information, use the following command.
You have several options for viewing interface status and configuration parameters.
• Lists all configurable interfaces on the chassis.
EXEC mode
show interfaces
This command has options to display the interface status, IP and MAC addresses, and multiple counters
for the amount and type of traffic passing through the interface.
If you configured a port channel interface, this command lists the interfaces configured in the port
channel.
NOTE: To end output from the system, such as the output from the show interfaces command,
enter CTRL+C and Dell Networking OS returns to the command prompt.
NOTE: The CLI output may be incorrectly displayed as 0 (zero) for the Rx/Tx power values. To obtain the
correct power information, perform a simple network management protocol (SNMP) query.
