CHAPTER 1: INTRODUCTION
Flash memory allows for the downloading of firmware to the module without requiring that the module be shut down. The firmware download may be performed at any time during the operation of the module, and the new firmware image will be utilized at the next reset of the module.
Expandable LDRAM
The EMM-E6 comes with 8 MB of Local Dynamic Random Access Memory (LDRAM). LDRAM is the “Main” memory from which the routing or bridging functionality of the EMM-E6 operates. When the EMM-E6 needs to support additional functionality, an LDRAM upgrade may be required. If you are planning to add any functionality to your EMM-E6 module, determine if an LDRAM expansion is required.
Expandable SDRAM
The EMM-E6 comes with 4 Megabytes (MB) of Shared Dynamic Random Access Memory (SDRAM). SDRAM holds packets coming onto the module temporarily while forwarding, filtering, and error checking decisions are made. While SDRAM has been designed to facilitate future expansion, at this time there are no EMM-E6 functions which require or are assisted by the expansion of SDRAM memory.
SNMP and RMON support
Since the EMM-E6 is SNMP compliant, you can control and monitor the device remotely and locally using different SNMP Network Management packages. EMM-E6 firmware also supports several RMON groups, including:
• | Alarms | • HostTopN |
• | Events | • | Matrix |
• | History | • | Statistics |
•Host
LANVIEW Diagnostic LEDs
Cabletron provides a visual diagnostic and monitoring system, called LANVIEW, with the EMM-E6. LANVIEW LEDs can help you quickly identify device, port, and physical layer problems.
