1.3.8
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 6C105 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.

LOCAL MANAGEMENT FEATURES
 
Local Management provides the tools that allow management of the 
6E12X-26 and 6E13X-25, the Fast Ethernet Interface Modules, all 
HSIMs, and the 6C105 chassis. Local Management for the 6E12X-26 and 
6E13X-25 provides the features detailed in Sections 1.4.1 through 1.4.6.
 
1.4.1
Distributed Chassis Management
 
From a management perspective, the 6C105 SmartSwitch 6000 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 6E12X-26 and 6E13X-25, can be used to manage 
the entire chassis, and any other attached module through Local 
Management, SNMP, or Telnet applications.
