Layer 2 switches support all the basic switching functionality. QoS, SNMP, POE, VLANs, Etc... depending on the model and features. Layer 3 switches are essentialy basic routers with a switch built in.
One thing about Cisco CDP and a lot of POE switches is you can get CDP support with a custom Ethernet cable, just swap pins 4-5 with 7-8 (This is how I'm running Cisco 7940G's with a Dell POE Switch). --------------------------------- William J McCloskey Information Technology Manager [EMAIL PROTECTED] 503-827-8141 503-228-6747 fax www.timbercon.com --------------------------------- -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Cory Andrews Sent: Monday, December 11, 2006 7:32 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: RE: [asterisk-users] Re: Recommendations for QoS, PoE Switches Edgewater Networks markets a 24 port switch, with PoE (both Cisco CDP and 802.3af supported), and Layer 2/3 management features that retails for less than $1500.
