Trunking Application Used With Switch; Single Ip - Agent Mode" Application Used With Switch - NetComm NP2624M User Manual

5.2. Trunking Application used with switch

Trunking allows you to increase the available bandwidth between switches by grouping ports into a
trunk. Trunking can also be used to connect servers to switches when higher bandwidth services are
required. You can use trunking to improve the throughput between segments. Moreover, this switch
also provides trunking with a fail-over function, that is, when one of the links of the trunk fails or
is broken, the traffic going through that link will automatically be re-directed to other links of the
trunk. This redundancy greatly increases the value of trunking.
5.3. "Single IP – Agent mode" application used with switch
Single IP is a management utility of network devices for administrators to access private IP devices
through a single IP (real IP or private IP). By this utility, an administrator can manage many more
network devices and reduce the demand of real IPs, because every real IP switch can be an agent
host for any network devices in their private IP domain.
There are some defects in the current solutions of network management. For example, switches
with legacy "stack" capability have to stack together due to their special limited-length cables, and
have the limitation of stacking quantities and brand compatibility due to hardware specification.
Moreover, the administrator always has trouble in finding out the target window among those multi-
display interfaces. Although there are expert network management utilities like HP OpenView,
available in the current market, they are too expensive to purchase and too difficult to implement
into embedded systems for their practical application.
Because of the rapid development of Ethernet, the scare of real IP shortage becomes a serious
issue when an enterprise continues its IA growth. It is a waste of money and resources for every
individual host to have its own real IP inside the enterprise's network. Privates IPs and NAT
function (provided by router, gateway or IP sharing) provide a solution to the shortage of real IP, but
gives rise to new issue that remote users from the internet have no access permission into the private
IP domain. Thus an administrator until now had no choice but to assess private IP devices from the
very location of the local area network to trouble shoot any problems that network clients report.
The "Single IP-Agent mode", one of this switch special features, provides a new solution for the
issues above.
There are benefits of "Single IP-Agent mode":
