Configure Switch Features
Redundant Gateways
Stratix 5400, Stratix 5700, ArmorStratix 5700 switches that support DLR also
support redundant gateways.
The redundant gateway feature provides redundant paths from a DLR
network to the outside network. You can configure multiple gateways and
assign each gateway a precedence value. Only one gateway can be active at any
given time. A backup gateway uses the configuration of the active gateway if the
active gateway becomes inactive. The network can switch from the active
gateway to a backup gateway within 14 ms…6.1 seconds, depending on the
uplink network redundancy protocol.
Typically, the redundant gateway feature is configured on trunk ports
independent of the DLR configuration of the access ports.
IMPORTANT
Redundant gateways do not work with End to End Transparent mode for
Precision Time Protocol. For more information about End to End Transparent
mode, see
.
IMPORTANT
The redundant gateway feature requires all devices on the ring to be
compatible with redundant gateway. Connections to devices wired to or
through a DLR network can be lost upon a gateway changeover if all DLR
network devices are not compatible with redundant gateway.
