Nick, Assuming this is a C2G124-24P or 48P, You could just shut POE off on all ports that aren't being used. This way the Cisco phone won't power up. Richard
Richard Hart Telecommunications Engineer Tidewater Community College From: Nick Allen [mailto:[email protected]] Sent: Tuesday, March 08, 2011 9:05 AM To: Enterasys Customer Mailing List Subject: [enterasys] Cross-connected switch... Hi, We have an office with an Enterasys C2G in it. Also in that office and in the same cabinet is a Cisco switch that belongs to another sister company. Devices plugged in the Cisco switch were getting IP address in the DHCP range that would normally be only available on the C2. We traced it with Compass to an IP phone with the passthrough port plugged into the Cisco switch instead of a workstation. What's the best way to prevent this happening from a config point of view on the Enterasys only (given that we don't have access to the Cisco). Thanks, Nick.
