Configuring The Ha Devices - AudioCodes Mediant 800B User Manual


If the two devices are connected through two (or more) isolated LAN switches (i.e.,
packets from one switch cannot traverse the second switch), configure the mode to
2RX/2TX:
Figure 41-2: Redundancy Mode for Two Isolated Switches

For Geographical HA (both units are located far from each other), 2Rx/1Tx port mode
connected to a port aggregation switch is the recommended option:
Note:
•
When two LAN switches are used, the LAN switches must be in the same subnet
(i.e., broadcast domain).
•
To configure Rx/Tx modes of the Ethernet ports, see 'Configuring Ethernet Port
Groups' on page 130
