This feature enables the 2E4X-27R 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 2E4X-27R is connected to the network and powered up, 
Runtime IP Address Discovery (RAD) checks the 2E4X-27R for an IP 
address. If one has not yet been assigned (2E4X-27R IP address set to 
0.0.0.0), RAD checks to see if any of the 2E4X-27R 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.

 

Management of the 2E4X-27R 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. Local 
Management can also be accessed through a Telnet connection to the 
RJ45 COM port.

Local Management provides the ability to manage the 2E4X-27R and any 
of the optional Fast Ethernet Interface Modules installed in ports 25 and 
26 and the optional High Speed Interface Module (HSIM). 

The user’s guide for the HSIM provides detailed information about Local 
Management for the HSIM.
