How Do You Handle Ethernet Port Management?

MTL-Stalker asks: "I am currently investigating the best way to handle Ethernet port management for an organization with over 75,000 Ethernet ports spread out over 700+ sites. I was wondering how members of the Slashdot community are handling this issue in their organizations? Obviously this is as much a business process issue as a technological solution. In today's threat-filled networks, it seems like asking for trouble to rely on a simple switch based 'port enabled/port disabled' methodology. Do you think Cisco-style port security (tying a MAC address to a particular port) or PACLs (port access control lists) are worth the effort? Are products like Cisco Campus Manager or HP OpenView worth the cost and deployment headaches? Do they address your security concerns? How many of you are using homegrown scripting and/or SNMP solutions? How many ports can you effectively manage with these solutions? I would also be interested in knowing what industries these solutions are being implemented in."

As far as port management goes, you may want to look at Netdisco. If I recall correctly, UC Santa Cruz was using it to manage about 20K ports. It's open source, so you so should be able to customize it for your environment. I haven't run it personally, but the demo looks impressive.

When considering how to secure the ports, I think you have to find the balance between security and functionality. If you lock down each MAC to a specific port, how much time will you spend managing it? Whenever there is a connectivity problem, will you have to fight with the other groups assuring them that it isn't the network?

As a final thought, you generally get out of a network management system what you put into it. With a network as large as yours, there isn't a silver bullet to fix all of your problems. Whether you customize, roll your own or use vanilla off the shelf software, you need to figure out what makes the most sense for your business. Good luck. It sounds like you need it.
