Network Management

Hi,

I need to check the health of my network. A tool that can give me the details of broadcast and multicast in the network, the LAN (fiber, copper) link utilization. If any host is making un-necessary broadcast i should be able to track it down from its MAC address or IP address.

Kindly suggests.

Regards

Amol

Re: Network Management

Hi Amol,

You can look at the following options to start with,

1) A sniffer tool to monitor the traffic patterns, broadcast and multicast levels in the network.

Later you can plan to have netflow monitoring enabled in your network to monitor the traffic patterns in your network, using which you can get extensive reports.

2) For link utilisation you can opt any freeware SNMP monitoring tools like MRTG.etc. which will give you clean graphical representation of link utilisation etc.

3) you can use the CLI show commands to trace any particular host in your network.

Hi,

I will just add that with MRTG you can get not only link utilization figures but practicaly every parameter possible to get from a device via SNMP. For example in my system I have graphs for link utilization, interface errors, CPU utilization, memory utilization and response time for several services in the network.

Re: Network Management

Hey Thanx Guys for this, let me try for MRTG.

My concern first started when i faced a slow network for one specific ODC. After troubleshooting it almost a month i came to know there was faulty NIC making unneccarry broadcast. I hope this tool can help me in one shot analysis.

Thx
