How to Configure CEP

The CEP (Convergence End Point) feature provides support for CEP products such as IP phones. Using this feature, you can select the CEP product types supported on a device, and map a role for each type. Then, when a convergence endpoint (such as an IP phone) connects to the network, the device identifies the type of endpoint and applies the assigned role. In addition to configuring CEP on a device, you must also enable CEP protocols on each port. Once you have configured CEP on the device and each port, you can monitor CEP product activity using the Port Usage tabs.

Use the Device Configuration Wizard and Port Configuration Wizard to configure CEP on multiple devices/ports, or follow these steps to enable it on a single device and port.

  1. Select a device in the left-panel Network Elements tab, and click the Authentication tab in the right panel.
  2. In the Authentication Type section, select the appropriate CEP checkbox: Single User or Multi-User. If the device does not support the CEP feature, the CEP checkboxes are grayed out.
  3. For Authentication Status, select Enabled.
  4. If you have configured Multi-User authentication types, set the authentication type precedence. This allows you to set the order in which the authentication types will be tried on the device, with the authentication type on the left having the highest precedence (it will be tried first). Select the authentication type you want to position, and use the left or right arrow to arrange the types in the desired order of precedence.
  5. Click Apply to set any changes you have made in this section.
  6. At the bottom of the window, click on the CEP tab.
  7. The CEP Detection sub-tab lists the CEP detection rules that are used to determine if a connecting end-system is a CEP device, and what type of CEP device it is. This allows Policy Manager to assign the appropriate role to the port based on the type of CEP device detected. Click Add to open the Add CEP Detection Rule window where you can create your detection rules. (For information on creating rules, see the Add CEP Detection Rule window help topic.) Your rules will be added to the list. To remove a rule from the list, select the rule and click Remove. To edit a rule, select the rule and click Edit. The Edit CEP Detection Rule window opens where you can edit the rule's parameters.
  8. Click Apply to set any changes you have made in the CEP Detection sub-tab.
  9. The CEP Role Mappings sub-tab lists the CEP types supported by the device and the role mapped to each type. Click Add to open the Add CEP Mapping window where you can select a CEP product type and map a role for that type. Your selections will be added to the list. To remove a CEP type from the list, select the type and click Remove. To edit a CEP type in the list, select the type and click Edit. The Edit CEP Mapping window opens where you can select a different CEP type and/or role.
  10. Click Apply to set any changes you have made in the CEP Role Mappings sub-tab.
  11. Now, select the right-panel Details View tab and expand a slot or ports grouping.
  12. Right-click the desired port and select Properties from the menu. In the Port Properties window, select the Authentication Configuration tab (in the top row of tabs).
  13.  Select the CEP Access sub-tab. The CEP Access table lists the protocols supported by this device.
  14. Use the checkboxes to enable or disable CEP protocols for this port.
  15. Click Apply to set any changes you have made in the tab.
  16. Repeat steps 12 through 15 for each port on the device where you want to enable CEP support.
