Feature Summaries

The following summaries describe VH-8TX1UM/VH-8TX1MF features in areas such as standards compliance, functionality, performance, and options.

IEEE 802.1D Bridge

The VH-8TX1UM/VH-8TX1MF switch is fully compliant with IEEE 802.1D transparent bridging specifications. An address table is provided for learning, filtering, and forwarding. The switch can support up to a maximum of 8K addresses. Addresses are automatically learned by the switch, and can be individually assigned specific forwarding treatment by the network administrator if desired. Forwarding table configuration can be made

out-of-band via the console interface or in-band via SNMP or Telnet. Static and dynamic addresses are both stored in this table. One static address is assigned per port by default. The Static Unicast Address Table Configuration screen in the console menus allows you to assign additional static addresses if required.

Spanning Tree Protocol

The VH-8TX1UM/VH-8TX1MF switch supports the IEEE 802.1D Spanning Tree Protocol. This protocol allows redundant connections to be created between different LAN segments for purposes of fault tolerance. Two or more physical paths between different segments can be created through the switch, with the Spanning Tree Protocol choosing a single path at any given time and disabling all others. If the chosen path
