Hi Nick,
Use Policy to only allow DHCP from a specific server? Kind regards, Simon Read Service Engineer Nashua Communications (Pty) Ltd. Unit 10 Growthpoint Business Park, No 2 Tonnetti Street, Midrand, 1685 M: +27 84 676 9200 Fax: +27100012500 [email protected] <mailto:[email protected]> www.nashua-communications.com <http://www.nashua-communications.com> From: Nick Allen [mailto:[email protected]] Sent: 08 March 2011 04:05 PM 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.
