NETWORK MANAGEMENT

The Engineering Department to twelve persons in a small corporation is on a regular 10 Base-T Ethernet Lan hub with 16 ports. The busy group started complaining because of the slow network performance. The network was operating at 50% utilization, whereas 30% utilization is acceptable. If you are the corporation’s Information Technology Engineer and have to resolve the problem technically,

a. Describe four choices for resolving the problem, maintaining the LAN as an Ethernet LAN.

b. State the advantages and disadvantages of each approach.

1. Two virtual LANs, 145.50.50.1 belonging to NM lab, and 145.50.60.1 belonging to Networking lab, each have three workstations. The former has workstations 145.50.50.11-13, and the latter 145.50.60.21.-23. They are connected to a switched hub on ports 2 through 7. the NICs (network interface cards) associated with ports are made by Cabletron and their MAC addresses start with the vendor’s global prefix 00-00-1D (hexadecimal notation) and end with 11,12,13,21,22, and 23 (same as the fourth decimal position of IP addresses).

2.

a. Create a conceptual matrix table, as shown below, that would be

generated by the hub that relates the IP address, MAC address,

and port number.

3.

|IP Address |MAC Address |Port Number |

| | | |

b. The workstation 23 is moved from networking lab to NM lab.

The appropriate parameter changes in the hub and the workstation.

3. Design a client/server network with two servers operating at...
