Chapter 1: Introduction
1-4 DLE28-MA User’s Guide
a wide variety of industry standard MIBs including RFC 1213 (MIB II),
RFC 1757 (RMON), RFC 1493 (Bridge MIB) and RFC 1354 (FIB MIB).
A full suite of DIGITAL Enterprise MIBs provide a wide array of
statistical information to enhance troubleshooting.
1.1.6 LANVIEW Diagnostic LEDs
LANVIEW diagnostic LEDs serve as an important troubleshooting aid by
providing an easy way to observe the status of individual ports and overall
network operations. Chapter 4 provides details about the DLE28-MA
LANVIEW LEDs.
1.1.7 Year 2000 Compliant
The DLE28-MA has an internal clock that can maintain the current time
and date beyond the year 1999.
1.1.8 Runtime 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
BootP or RARP server on the network.
The RAD requests start out at an interval of 1 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 BootP or RARP
server, or an IP address is entered using Local Management.
