Figure 3-94. The UPnP Configuration
Parameter Description
These parameters are displayed on the UPnP Configuration page:
• Mode: Indicates the UPnP operation mode. Possible modes are:
- Enabled: Enable UPnP mode operation.
- Disabled: Disable UPnP mode operation.
When the mode is enabled, two ACEs are added automatically to trap UPNP related packets to CPU. The ACEs are automatically
removed when the mode is disabled.
• TTL: The TTL value is used by UPnP to send SSDP advertisement messages. Valid values range from 1 to 255.
• Advertising Duration: The duration, carried in SSDP packets, is used to inform a control point (or control points) how often it (or
they) should receive an SSDP advertisement message from this switch. If a control point does not receive any message within
the duration, it will think that the switch no longer exists. Because of the unreliable nature of UDP, the standard recommends
that such refreshing of advertisements should be done at less than one-half of the advertising duration. In the implementation,
the switch sends SSDP messages periodically at the interval of one-half of the advertising duration minus 30 seconds. Valid val-
ues range from 100 to 86400.
• Buttons:
- Save: Click to save changes.
- Reset: Click to undo any changes made locally and revert to previously saved values.
