Ethernet Redundancy
With two Ethernet modules, IPmux-8/16 supports Ethernet redundancy to back up
TDMoIP traffic if there is a failure in the Ethernet line. The system assigns the same
IP and MAC addresses to each Ethernet interface, so that if a failure occurs, the
data and management traffic will automatically switch to the second Ethernet
module. The switching is transparent to the remote IPmux, and the switches and
routers in the network. Ethernet redundancy provides a backup for the link and
module.
Enabling or disabling Ethernet redundancy can result in erasing all bundle
configurations, depending on the CES card arrangement. Refer the table below for
more exact information.

E1/T1 CES card is available only for IPmux-16.
• Ethernet redundancy is not possible when two E3 or T3 modules are installed.
Load Sharing
When IPmux-8/16 includes two Ethernet modules, the TDM data can be divided
between them, so that there is a smaller load on each network link. The TDM data
from slot 3 is mapped to the Ethernet module installed in slot 1, and the TDM data
from slot 4 is mapped to slot 2.
Internal Switch Operation Modes
4-port Ethernet modules of IPmux-8/16 offer up to three user ports in addition to
the network port. The device performs switching at Layer 2. The switch supports
both transparent bridging and VLAN-aware bridging. The switch supports rate
limiting of traffic going from the user ports to the network port. It supports up to
1024 MAC addresses (depending on their values and the order in which they are
learned).
