Enabling Cut-Through Switch Forwarding

The following example for Dell PowerConnect 6200 series switches cover enabling cut-through switching

globally on the switch and begins assuming the user is in privileged EXEC mode.

Note: Cut-through mode does not support passing packets from lower to higher speed network interfaces as it

disrupts the continuous flow of data model. Hence, Dell PowerConnect 6200 series switches can not cut-

through data traffic from 1G to 10G ports, and will instead use store-and-forward in this transaction.

Note: Cut-through mode on the Dell PowerConnect 6200 series switches does not take effect till reboot.

Please remember to copy your running-config to the startup-config prior to rebooting the switch for cut-

through mode to take effect.

Dell PowerConnect 6200 Series CLI Example:

# configure

# cut-through mode

# exit

# copy running-config startup-config

# reload

Please see your switch model’s documentation for further information regarding specific Packet Forward mode

support and configuration.

Enabling QoS

PS series arrays will benefit from QoS settings permitting iSCSI traffic elevated packet priority. The

following examples for Dell PowerConnect 5400 and 6200 series switches cover enabling elevated

QoS support on switch interfaces. Note that if the PowerConnect 62xx switch is running FW

2.2.0.3 or greater, then the below QoS settings are not needed. The below examples begin

assuming the user is in privileged EXEC mode.

Note: The Dell PowerConnect 5400 series switches are iSCSI-aware and provide iSCSI flows with a

QoS profile that ensures that iSCSI endpoints connected via the switch will get a differentiated

service over other network traffic. The configuration settings are applied to the switch globally.
