Use the channelization feature to configure a single port to operate as four individual ports. Channelization can apply to the following port speeds:

You can use breakout direct attach cables (DAC) or transceivers with fiber breakout cables to connect the channelized ports to other servers, storage, and switches.

By default, the ports are not channelized, which means that the ports operate as one single port at the fully supported speed. You can enable or disable channelization on a port.

For the number of ports on the switch that support channelization, see the applicable hardware documentation.

If the product supports channelization and you enable or disable channelization on a port, the port QoS configuration resets to default values. For information about configuring QoS values, see Quality of Service.

Note

Note

When you use channelized ports in an Split Multi-Link Trunking (SMLT) configuration, the system does not display the channelized ports properly when you show MLT information for the remote port member if the remote switch runs a release that does not support channelization.

When a port is channelized, use only break out cables (copper or active optical DAC) in it. Using other cables in either a channelized port or a non-channelized port results in mismatched link status between link partners, which can lead to network issues.

SFP-DD Ports

Note

Note

Product Notice: SFP-DD ports are specific to 5420 Series.

Advanced Feature Bandwidth is enabled by default on the SFP-DD ports. When Advanced Feature Bandwidth is disabled, SFP-DD ports can operate as 1 Gbps ports with an SFP and as 10 Gbps ports with an SFP+. When the SFP-DD split DAC is used, SFP-DD ports can accept two SFP+ with 10 Gbps port speed.

Note

Note

SFP-DD split DAC applies to certain 5420 Series models.

For more information about SFP-DD ports, see 5420 Series.
