1.1.8 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 DLEHF-MA
LANVIEW LEDs.
1.1.9 Runtime IP Address Discovery
This feature enables the DLEHF-MA to automatically accept an IP
address from a BootP server on the network into NVRAM without
requiring the user to enter an IP address through Local Management.
When the DLEHF-MA is connected to the network and powered up,
Runtime IP Address Discovery (RAD) checks the DLEHF-MA for an IP
address. If one has not yet been assigned, RAD checks to see if any of the
DLEHF-MA interfaces has 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 and double 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.
1.2 LOCAL MANAGEMENT FEATURES
Local Management provides the tools that allow management of the
DLEHF-MA, the Fast Ethernet Interface Modules, all HSIMs, and the
DLM6C-AA chassis. Local Management for the DLEHF-MA provides
the features detailed in Sections 1.4.1 through 1.4.6.
1.2.1 Distributed Chassis Management
From a management perspective, the DLM6C-AA MultiSwitch 700
chassis can be viewed as a single entity with a single IP address. Its
management functions are distributed to all modules. This means a single
module in the chassis, such as the DLEHF-MA, can be used to manage
the entire chassis, and any other attached module through Local
Management, SNMP, or Telnet applications.
