Configuring A Default Stacking Port To Function As; A Data Port - Dell PowerConnect B-FCXs Configuration Manual

Configuring a default stacking port to function as

a data port

You can configure one of the two default stacking ports as a stacking port and the other port as a
regular data port. By default, the 4-byte Ethernet preamble for the Ethernet frame is used when a
port is configured as a default stacking port. This is done to compensate for extra overhead caused
by stacking protocol. To use a default stacking port as a regular data port, the Ethernet preamble
must be set to 8 bytes.
To configure a default port to use the long preamble, enter the following command at the Interface
level of the CLI:
PowerConnect(config)#int e 1/2/1
PowerConnect(config-if-e10000-1/2/1)#longpreamble
Syntax: [no] longpreamble
