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 long-preamble command at the
Interface level of the CLI.
Brocade(config)#interface ethernet 1/2/1
Brocade(config-if-e10000-1/2/1)#long-preamble
Syntax: [no] long-preamble
Use the no form of the command to revert to the 4-byte Ethernet preamble.
