Connecting Multiple Hosts
If more than one host is configured, a
Host Mode
option appears. Host Mode controls how
multiple hosts will be accessed. For the PremierWave device, the Connect Mode supports up to 32
hosts. Hosts may be accessed sequentially or simultaneously:
Sequential
– Sequential host lists establish a prioritized list of tunnels. The host specified as
Host 1 will be attempted first. If that fails, it will proceed to Host 2, 3, etc, in the order they are
specified. When a connection drops, the cycle starts again with Host 1 and proceeds in order.
Establishing the host order is accomplished with host list promotion (see
). Sequential is the default Host Mode.
Simultaneous
– A tunnel will connect to all hosts accepting a connection. Simultaneous
connections occur at the same time to all listed hosts. The device can support a maximum of
64 total aggregate connections.
Host List Promotion
This feature allows Host IP promotion of individual hosts in the overall sequence.
To promote a specific Host:
1. Click the
icon in the desired Host field, for example Host 2 and Host 3.
2. The selected Host(s) exchanges its place with the Host above it.
3. Click
Submit
. The hosts change sequence.
Disconnect Mode
Specifies the optional conditions for disconnecting any Accept Mode or Connect Mode connection
that may be established. If any of these conditions are selected but do not occur and the network
disconnects to the device, a Connect Mode connection will attempt to reconnect. However, if none
of these conditions are selected, a closure from the network is taken as a disconnect.
