1.1.1.31 Portal Escaping Examples
Fig 15-7 Portal server escaping function case
As shown above, in the situation of the normal working of portal server, the portal
authentication can be normal for the network accessing when client is on-line. When th
e portal server is down or the connection between it and switch is broken, client canno
t authenticate to on-line if the portal escaping function is not enabled on switch. If the
portal escaping function is enabled on switch, switch can probe that the portal server is
unavailable and start the portal escaping function. And the client can access the netw
ork without authentication. If client has passed the authentication before the portal serv
er is broken, it will not be affected and it can still access the network.
