Switchport - Dell Force10 Z9000 Reference Manual

The quad port must be in a default configuration before it can be split into 4x10G ports. The 40G
port is lost in the config when the port is split, so be sure the port is also removed from other
L2/L3 feature configurations.
The system must be reloaded after issuing the CLI for the change to take effect.

switchport

Place an interface in Layer 2 mode.
C-Series, E-Series, S-Series, Z-Series, S4810
Syntax switchport [backup interface {gigabit slot/port | tengigabit
slot/port | fortyGigE slot/port | port-channel number}]
To remove an interface from Layer 2 mode and place it in Layer 3 mode, enter the no
switchport command. If a switchport backup interface is configured, you must first remove
the backup configuration. To remove a switchport backup interface, enter the no
switchport backup interface {gigabit slot/port | tengigabit
slot/port | fortyGigE slot/port | port-channel number} command.
Parameters

• The unit number with the split ports must be the default (stack-unit 0).
• This can be verified using CLI show system brief. If the unit ID is different than
0, it must be renumbered to 0 before ports are split by using the stackunit id
renumber 0 command in EXEC mode.
Use this option to configure a redundant Layer 2 link without using
Spanning Tree. The keywords backup interface configures a
backup port so that if the primary port fails, the backup port changes
to the up state. If the primary later comes up, it becomes the backup.
Enter the keyword gigabit if the backup port is a 1G port.
Enter the keyword tengigabit if the backup port is a 10G port.
Enter the keyword fortyGigE if the backup port is a 40G port.
Enter the keywords port-channel if the backup port is a static or
dynamic port channel.
Specify the line card and port number of the backup port.
Introduced on the Z9000.
Added support for 4-port 40G line cards on ExaScale.
Added support for port-channel interfaces (the port-channel
number option).
