7. With dual-radio model Brocade Mobility 7131N-FGR Access Point, refer to the Mesh Timeout
drop-down menu to define whether one of the radio’s beacons on an existing WLAN or if a
client bridge radio uses an uplink connection. The following drop-down menu options are
available:
NOTE
The Mesh Time Out variable overrides the Ethernet Port Time Out (EPTO) setting on the LAN
page when the access point is in bridge mode. As long as the mesh is down, the access point
acts in accordance to the Mesh Time Out setting regardless of the state of the Ethernet.
However, if the Ethernet goes down and the mesh link is still up, the EPTO takes effect.
For a detailed overview on mesh networking and how to configure the radio for mesh
networking support, see
“Configuring mesh networking support” on page 523.
8. Click Apply to save any changes to the Radio Configuration screen. Navigating away from the
screen without clicking Apply results in all changes to the screens being lost.
CAUTION
When defining a Mesh configuration and changes are saved, the mesh network temporarily goes
down. The Mesh network is unavailable because the access point radio is reconfigured when
applying changes. This can be problematic for users making changes within a deployed mesh
network. If updating the mesh network using a LAN connection, the access point applet loses
connection and the connection must be re-instated. If updating the mesh network using a WAN
connection, the access point applet does not lose connection, but the mesh network is
unavailable until the changes have been applied.
9. Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the
settings displayed on the Radio Configuration screen to the last saved configuration.
10. Click Logout to securely exit the Access Point applet. A prompt displays confirming the logout
before the applet is closed.
Disabled When disabled, both radios are up at boot time and beaconing. If
one radio (radio 1) does not have a mesh connection, the other
radio (radio 2) is not affected. Radio 2 continues to beacon and
associate MUs, but MU's can only communicate amongst
themselves using the access point. Disabled is the default value.
Uplink Detect When Uplink Detect is selected, the access point only boots up the
radio configured as a client bridge. The access point boots up the
second radio as soon as the first mesh connection is established.
However, if the client bridge radio loses its uplink connection, the
second radio shuts down immediately. Uplink detect is the
recommended setting within a multi-hop mesh network.
Enabled If the mesh connection is down on one radio (radio 1), the other
radio (radio 2) is brought down and stops beaconing after the
timeout period (45 - 65535 seconds). This allows the client bridge
(radio 1) to roam without dropping the MU's associated to radio 2.
The disadvantage is that radio 2 may beacon for the timeout
period and have to drop associated MU's because radio 1 could
not establish its uplink. The default timeout period is 45 seconds.
