ICX 6430 device port regions

• A 24-port Gbps module has one port region. The four SFP ports on the device also belong to this

single port region.

• A 48-port Gbps module has two port regions:

Ports 1-24 and SFP ports 1& 2 belong to port region 0

Ports 25-48 and SFP ports 3 & 4 belong to port region 1

ICX 6450 device port regions

• A 24-port Gbps module has one port region. The four SFP+ ports on the device also belong to this

single port region.

• A 48-port Gbps module has two port regions:

Ports 1-24 and SFP+ ports 1& 2 belong to port region 0

Ports 25-48 and SFP+ ports 3 & 4 belong to port region 1

ICX 6650 device port regions

ICX 6650 device has only one port region.

Brocade ICX 6650 has only one port region. All ports belong to region 0.

ICX 7750 device port regions

Brocade ICX 7750 has only one port region. All ports belong to region 0.

Enabling or disabling the Spanning Tree Protocol (STP)

STP (IEEE 802.1D bridge protocol) is supported on all Brocade devices. STP detects and eliminates
logical loops in the network. STP also ensures that the least cost path is taken when multiple paths
exist between ports or VLANs. If the selected path fails, STP searches for and then establishes an
alternate path to prevent or limit retransmission of data.

NOTE
This section provides instructions for enabling and disabling STP. For configuration procedures and
more information about STP, refer to

Spanning Tree Protocol

on page 251 in this guide.

STP must be enabled at the system level to allow assignment of this capability on the VLAN level. On
devices running Layer 2 code, STP is enabled by default. On devices running Layer 3 code, STP is
disabled by default.

To enable STP for all ports on a Brocade device, enter the following command.

device(config)#spanning tree

Syntax: [no] spanning-tree
