Unified Access

The Summit 300-48 supports the Unified Access architecture, enabling wired and wireless applications
across a completely integrated enterprise infrastructure. With the Altitude product line, the Summit
300-48 supports 802.11 WLAN connectivity. Provisioning of Unified Access is completely controlled by
the Summit 300-48.

Virtual LANs (VLANs)

ExtremeWare has a VLAN feature that enables you to construct your broadcast domains without being
restricted by physical connections. A VLAN is a group of location- and topology-independent devices
that communicate as if they were on the same physical local area network (LAN).
Implementing VLANs on your network has the following three advantages:
• They help to control broadcast traffic. If a device in VLAN Marketing transmits a broadcast frame,
only VLAN Marketing devices receive the frame.
• They provide extra security. Devices in VLAN Marketing can only communicate with devices on
VLAN Sales using routing services.
• They ease the change and movement of devices on networks.
NOTE
For more information on VLANs, see Chapter 5, "Virtual LANs (VLANs)".

Spanning Tree Protocol

The Summit 300-48 supports the IEEE 802.1D Spanning Tree Protocol (STP), which is a bridge-based
mechanism for providing fault tolerance on networks. STP enables you to implement parallel paths for
network traffic, and ensure that:
• Redundant paths are disabled when the main paths are operational.
• Redundant paths are enabled if the main traffic paths fail.
A single spanning tree can span multiple VLANs.
NOTE
For more information on STP, see Chapter 13, "Spanning Tree Protocol (STP)".
