NBR Features

MIB Navigation

NBR ﬁrmware supports a management tool which allows for MIB navigation from a remote station. Refer to the NBR-220,NBR-420, and NBR-620 Local Management Guide for more information regarding MIB navigation.

Spanning Tree Protocol Support

The NBR supports the following spanning tree protocols:

•802.1d

•DECnet

Serial Connections/Local Management

The NBR-220 provides one RJ45 port (COM) for serial connections and the NBR-420 and NBR-620 provide two RJ45 ports (COM 1 and COM 2). These ports allow you to access Local Management by locally connecting a DEC VT220 or VT320 terminal, or a PC using VT emulation software. Refer to your NBR-220,NBR-420, and NBR-620 Local Management Guide for additional information on how to use Local Management. In addition, any of the COM ports can be used as an Uninterruptible Power Supply (UPS) management port.
