Cabletron Systems DLE23-MA, DLE33-MA, DLE22-MA Year 2000 Compliant, Runtime IP Address Discovery

DLE2X-MA and DLE3X-MA Overview

1.1.8Year 2000 Compliant

The DLE2X-MA and DLE3X-MA have an internal clock that can maintain the current time and date beyond the year 1999.

1.1.9Runtime IP Address Discovery

This feature enables the modules to automatically accept an IP address from a BootP server on the network into NVRAM without requiring a user to enter an IP address through Local Management.

When the modules are connected to the network and powered up, Runtime IP Address Discovery (RAD) checks the modules for an IP address. If one has not yet been assigned (module and DLM6C-AA chassis IP address set to 0.0.0.0), RAD checks to see if any of the module interfaces have a link. If so, RAD sends out Reverse Address Resolution Protocol (RARP) and BootP requests to obtain an IP address from a RARP or BootP server on the network.

The RAD requests start out at an interval of one second. The interval then doubles after every transmission until an interval of 300 seconds is reached. At this point, the interval remains at 300 seconds. The RAD requests continue until an IP address is received from a RARP or BootP server, or an IP address is entered using Local Management.

1.1.10 Local Management Features

Local Management provides the tools that allow management of the DLE2X-MA and DLE3X-MA, the Fast Ethernet Interface Modules, the High Speed Interface Module (HSIM) and the DLM6C-AA chassis. It also allows the following tasks to be performed:

•Manage any module installed in the DLM6C-AA via a single terminal connection.

•Assign an IP address and subnet mask to the DLM6C-AA chassis, DLE2X-MA and DLE3X-MA.

•Select a default gateway.

•Control local and remote access.
