Spanning Tree Protocol
The TigerSwitch 1000 supports ANSI/IEEE 802.1d Spanning Tree
Protocol. This protocol adds a level of fault tolerance by allowing
two or more redundant connections to be created between a pair
of LAN segments. When there are multiple physical paths between
segments, the protocol will choose a single path and disable all
others to ensure that only one route exists between any two
stations on the network. This prevents the creation of network
loops. However, if the chosen path should fail for any reason, an
alternate path will be activated to maintain the connecti on.
The default setting for the Spanning Tree Protocol is “enabled.”
This protocol may be configured (enabled or disabled)
out-of-band via the serial console port or in-band via the Web
interface, Telnet, or SNMP network management software.
VLANs
The TigerSwitch 1000 supports up to 256 VLANs. A Virtual LAN is
a collection of network nodes that share the same collision domain
regardless of their physical location or connection point in the
network. By segmenting your network into VLANs, you can:
•Eliminate broadcast storms which severly degrade performance
in a flat network.
•Simplify network management for node changes/moves by
remotely configuring VLAN membership for the concerned
port, rather than having to manually change the node ’s IP
address.
•Provide data security by restricting all traffic to the originating
VLAN, except where a connection has been configu red
between separate VLANs using a router or Layer 3 sw itch.
