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."
