Cabletron Systems 2E42-27R Manual Do Utilizador

 

Introduction

 

This feature enables the 2E42-27 to automatically accept an IP address 
from a Boot Strap Protocol (BootP) server on the network into NVRAM 
without requiring a user to enter an IP address through Local 
Management.

When the 2E42-27 is connected to the network and powered up, Runtime 
IP Address Discovery (RAD) checks the 2E42-27 for an IP address. If one 
has not yet been assigned (2E42-27 IP address set to 0.0.0.0), RAD 
checks to see if any of the 2E42-27 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 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 server, or 
an IP address is entered using Local Management.

 

Management of the 2E4X-27 is accomplished using SNMP compliant 
management tools for in-band management. Out-of-band Local 
Management is provided through the RJ45 COM port on the front panel 
using a VT100 terminal or a VT100 terminal emulator. In-band remote 
management is possible through any SNMP compliant Network 
Management Software.

Local Management provides the ability to manage the 2E4X-27 and any 
of the optional Fast Ethernet Interface Modules installed in ports 15 and 
16 and the optional High Speed Interface Module (HSIM). 

The associated High Speed Interface Module user’s guide provides 
detailed information about Local Management of the HSIM.
