Since the NBR is SNMP compliant, you can control and monitor the
device remotely and locally using different SNMP Network Management
packages. NBR firmware also supports DLM and all RMON groups,
including:
• Alarms
• Hosts Top N
• Events
• Matrix
• History
• Statistics
• Hosts
• Filter
• Packet capture
D.2 ETHERNET CHANNELS A, B, C, AND D
The NBR manages all Ethernet bridging traffic within its resident hub.
This means that the NBR-620 controls up to four of the Ethernet bridging
channels—A, B, C, and D and the NBR-220 and NBR-420 control up to
two channels—A and B. These channels access the same NBR shared
memory, so bridging between channels is concurrent.
D.3 CHANNELS E AND F
The NBR-420 and NBR-620 support two optional Bridge/Router
Interface Modules (BRIMs). These modules provide additional
connectivity and either bridging or routing functions for your NBR. At the
same time, BRIMs provide access to various transmission methods (e.g.,
ATM, FDDI, Wide Area, etc.).
NOTE
Refer to the Customer Release Notes to see which BRIMs are
supported.
