Usage
Information
Splitting a 40G port into 4x10G port is supported only on a standalone unit.
• Split ports cannot be used as stack-link to stack an S5000.
• Split ports on the S5000 cannot be a part of any stacked system.
• 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.
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.
S5000
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.
