3Com 3800 - Manual (Page 23)

Network Configuration Example 1-5
Priority Access Control Enabled (PACE)
The Switch recognizes the PACE bit set by 3Com Etherlink ® adapters
and other devices supporting PACE. When enabled, traffic with these
bits receives priority service from the Switch.
Spanning Tree Protocol (STP)
The Switch 3800 supports the IEEE 802.1d Spanning Tree Protocol
(STP), which is a bridge-based mechanism for providing fault tolerance
on networks. STP allows you to implement parallel paths for network
traffic, and ensure the following:
■
Redundant paths are disabled when the main paths are operational.
■
Redundant paths are enabled if the main traffic paths fail.
For more information on STP, refer to Chapter 7.
IP Unicast Routing
The Switch 3800 can route IP traffic between the VLANs configured as
virtual router interfaces. Both dynamic and static IP routes are
maintained in the routing table. RIP version 1 and RIP version 2 are
supported.
For more information on IP unicast routing, refer to Chapter 8.
Network
Configuration
Example This section describes where to position the Switch 3800 within your
network. One common use of the Switch 3800 is on a Gigabit Ethernet
backbone. Figure 1-2 shows an example of a Gigabit Ethernet
backbone within a building.
