Enable Channelization

Enable channelization on a port to configure it to operate as four channels, or ports.

Note

Note

The switch automatically channelizes a port if the port operates in Auto-sense mode and you insert a QSFP+ to SFP+ or QSFP28 to SFP28 adapter, or a breakout cable.

About this task

Important

Important

Enabling or disabling channelization resets the port QoS configuration to default values.

Procedure

  1. Enter GigabitEthernet Interface Configuration mode:

    enable

    configure terminal

    interface GigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...]}

    Note

    Note

    If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.

  2. Enable channelization on a port:

    channelize [port {slot/port[-slot/port][,...]}] enable

  3. Display the status of the ports:

    show interfaces gigabitEthernet channelize [{slot/port[-slot/port][,...]}]

    To display the details of the sub-ports, use:

    show interfaces gigabitEthernet channelize detail [{slot/port/sub-port[-slot/port/sub-port][,...]}]

  4. Optional: To disable channelization on a port, enter:

    no channelize [port {slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}] enable

Examples

Switch:1> enable
Switch:1# configure terminal
Switch:1(config)# interface gigabitethernet 2/1
Switch:1(config-if)# channelize enable
Enabling channelization on port 2/1. Subport 2/1/1 will inherit port 2/1 configuration. Subports 2,3,4 will use default config. QSFP will be reset as removal and re-insert.
    NOTE: Modify QOS configurations on all subports as required.

Display the port status:

Switch:1(config)# show interfaces gigabitEthernet channelize 2/2-2/4

The following is an example of how to disable channelization on a port:

Switch:1> enable
Switch:1# configure terminal
Switch:1(config)# interface gigabitethernet 2/2/1
Switch:1(config-if)# no channelize enable

The following example shows a device inserted into a port and auto channelized:

Variable Definitions

The following table defines parameters for the channelization command.

Variable

Value

{slot/port[/sub-port][-slot/port[/sub-port]][,...]}

Identifies the slot and port in one of the following formats: a single slot and port (slot/port), a range of slots and ports (slot/port-slot/port), or a series of slots and ports (slot/port,slot/port,slot/port). If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.
