Simple Network
... [Show More] Management Protocol (SNMP) is a protocol which allows the user to
view how the network is managed/monitored. Currently there are 3 versions on SNMP;
SNMPv1, SNMPv2/c and SNMPv3. In SNMP, there are two main factors in which the
protocol follows, one being the Manager and the second Agent. A Manager is an
application in which the manager receives and manages requests coming from the
SNMP Agent, and an Agent is simply a software that detects traps messages (aka Alerts)
which is sent to the manager. (“Agents, Managers, and Subagents” n.d.) These trap
messages identify the possible risks that can occur in the user’s hardware and software,
which is why SNMP is needed to manage the operations of the network.
2.0 Discussion
For this project, the very first thing to do was to create a topology (Figure 1.1) and
this was achieved by using Cisco’s Packet Tracer Software. As shown in Figure 1.1,
there are currently three routers, three switches and three computers that are being
used. The following table (Figure 1.2) shows how each device is connected and what
significance they have such as PC105 being the Manager and S105 being the bridge
(name configuration shown in Figure 3.1). The next step was to route each PC to
their respective router. As shown in Figures 2.2 - 2.6 all devices were connected with
IP addressing and their serial ports for routers. Specifically for R105, this acts as the
central router connecting both R104 and R106 and this can only be done through
RIP routing (Figure 2.6). For configuring the routers, this routing protocol was used
to allow easy routing and optimization when configuring. When compared to
connecting routers using the Command-line interface (CLI), though optimization is
better to work with, for this report using the automatic RIP routing (Figure 2.6) was
more convenient due to the time it took to route. This interface wasn’t timely and it
was easy to configure routers because instead of typing code, this interface only
needed the routers IP address with their respective serial port. In R105’s case, the
first router’s address (10.0.0.2) came from serial 0/0/0 and the second router’s
address (11.0.0.3) came from serial 0/1/0. As for PC’s to configure each one, every
PC needed an IP address and a gateway to connect with each other (Figures 2.2 -
2.6). For this report, the following switches S104, S105 and S106 will not have an IP
address due to the switches acting as a bridge between the connection of Computers
and Routers. The switches are unmanaged and therefore does not require an IP
address (“Network Engineering” n.d) and for this report the switches are only
configured with the main purpose of enabling them to have community strings
(Figure 3.1), which will later be explained throughout the report. [Show Less]
