A WPP portal group allows users to configure up to eight WPP portals in a portal group. The system can receive portal-initiated WPP request packets from any configured portal in the portal group. When the system must initiate a WPP NTF_LOGOUT message, it sends a NTF_LOGOUT message to all configured portals in the portal group, and the first received ACK_LOGOUT stops retransmission of the NTF_LOGOUT message.
A WPP portal group can be used to achieve WPP portal redundancy:
Each portal is only allowed to be configured in a single portal group
Each can be in a portal group and be used as an individual portal simultaneously
Mixed WPP versions (version 1 and version 2) of portals are allowed in the same portal group
This feature is also supported for WPP triggered hosts and SRRP/MCS.
