GbE port-pair 1 is composed of physical ports 1 and 2 (either one can be
configured as primary and the other as backup.
GbE port-pair 2 is composed of physical ports 3 and 4 (either one can be
configured as primary and the other as backup.
When operating in the Dual port-pair mode, only one of the physical GBE ports in a
pair can be used to receive input traffic (except for the Stream Redundancy detection
mode, explained later, where both ports of a pair can be used to receive multicast
stream). This port is termed as the Active port of the port pair. If a fault occurs on
the current Active port, the RF Gateway 1 will failover to the next physical port.
To facilitate network operation of GbE port redundancy, the RF Gateway 1
implements a single, user-configurable Video/Data IP address for each port-pair.
The Video/Data IP address is assumed by the active port of the port-pair. If a
failover occurs from an active port to a backup port, the backup port assumes the
Video/Data IP address once it becomes active. For all modes of operation, any
unicast streams destined for the RF Gateway 1 must be sent to the Video/Data IP
address for a given port-pair. The RF Gateway 1 does not implement a layer 2
address. Each physical GbE port is assigned a static, non-configurable MAC address.
In this manner, the active physical port of a given port-pair assumes the Video/Data
IP address of the port-pair, but retains its own unique hard-coded MAC address.
Several user-configurable options are available to the operator regarding
redundancy, including:
-
auto vs. manual operation
-
revertive vs. non-revertive
-
detection mode
Manual Redundancy Mode
The Active port of the pair is set by the user and remains fixed until changed by the
user again. It does not depend on the Port or Network status. The active port can be
either port 1 or 2 for the first pair and port 3 or 4 for the second pair.
Auto Redundancy Mode
This is the default redundancy mode of the input ports. When operating in the Auto
Redundancy mode, the RFGW-1 will dynamically select the Active port for a pair
based on the Port and/or the network condition. The user can configure the
condition that will trigger the change in the current Active port of the pair. The
triggers are referred to as Detection modes. Three different detection modes are
available,
Ethernet Link
Ethernet Link + UDP/L2TPv3 packets
Ethernet Link + UDP/L2TPv3 p TS Socket
