4.93 UPnP
This page allows the user to configure the UPnP parameters for the switch.
4.93.1 UPnP Configuration The displayed settings are:
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 are in the range 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. Due to the unreliable nature of UDP, in the standard it is recommended that such refreshing of advertisements to be done at less than one-half of the advertising duration. In the implementation, the switch sends SSDP messages periodically at the interval one-half of the advertising duration minus 30 seconds. Valid values are in the range 100 to 86400.
