Convergence End Point (CEP)

CEP detects an IP telephony or video device on a port and dynamically applies a specific policy to the port. The switch detects a convergence end point by inspecting received packets for specific traffic attributes. CEP does not require a RADIUS configuration.

The CEP implementation supports the following detection methods:

• Cisco Phone Detection - the firmware parses a Cisco Discovery Protocol (CDP) packet to identify the phone type. If it was sent by an IP phone, the firmware uses the phone type. A response is sent back to the phone, verifying authentication.
• Siemens HiPath Phone Detection - TCP/UPD port number snooping is used. Port 4060 is the default port for communication.
• H.323 Phone Detection - TCP/UDP port number snooping and reserved IP address snooping are used. Ports 1718 - 1720 and IP address 224.0.1.41 are the default values.
• LLDP-MED – Detects LLDP-MED on the specified port.
• Session Initiation Protocol (SIP) Phone Detection - TCP/UDP port number snooping and reserved IP address snooping are used. Port 5060 and IP address 224.0.1.75 are the default values.

CEP agent accounting is supported and defaults to disabled. To use CEP agent accounting RADIUS accounting must be enabled using the set radius accounting command. PWA agent accounting can be enabled using the set pwa accounting command.
