Cabletron Systems 2E43-51R User Manual

 

When Auto-Negotiation is supported at both ends of a link, the two 
devices dynamically adjust to full or half duplex operation based on the 
maximum capability that can be reached between the two devices. If the 
device connected to the FE-100TX cannot auto-negotiate, the FE-100TX 
Fast Ethernet Interface Module operates according to the capabilities of 
the other device.

 

SmartTrunk, also referred to as SmartTrunking, is Cabletron Systems’ 
terminology for load balancing or load sharing. SmartTrunk technology 
provides an easy-to-implement mechanism to group, or aggregate, 
multiple physical links together to scale the backbone bandwidth beyond 
the limitations of a single link. All links are user-configurable so 
administrators can scale the backbone bandwidth by adding SmartTrunk 
links. The SmartTrunk benefits are as follows:

 

All purchased bandwidth is used.

 

Distributed, resilient links increase reliability and performance.

 

Multiple technologies are supported within a single trunk for 
maximum flexibility.

This feature enables the 2E43-51 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 2E43-51 is connected to the network and powered up, Runtime 
IP Address Discovery (RAD) checks the 2E43-51 for an IP address. If one 
has not yet been assigned (2E43-51 IP address set to 0.0.0.0), RAD 
checks to see if any of the 2E43-51 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.
