. If you plan to support the extensible messaging and presence protocol (XMPP) for your deployment, select the Enable XMPP federation (port 5269) check box (for the external edge server interface).
. The number 5269 and 23456 that is passed to findstr as a parameter instructs findstr to search the output of netstat for the strings 5269 and 23456. If XMPP is correctly configured, the result of the commands should result in listening and established connections, both on the external (port 5269) and the internal (port 23456) interfaces of the Edge Server.
