Chapter 1: Introduction
1.4.4Runtime IP Address Discovery
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.
1.4.5Management
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.
Information about how to access and use Local Management is contained in Chapter 5.
