Port And Switch Redundancy Configuration; Rstp Configuration - Avaya G430 Manual

Supported LAN deployments
When the gateway senses that the link is out of service at the primary port, it automatically
enables the secondary link. Both the ports must be administratively enabled on the LAN switch
peer.

Port and switch redundancy configuration

Branch Gateway can be deployed in the LAN using port and switch redundancy to provide
redundancy. Branch Gateway is connected to two external LAN switches. Each of the Ethernet
LAN ports located on the Branch Gateway's front panel is connected to one of the switches.
One of the Ethernet LAN ports is configured to be the active primary link, and the other Ethernet
LAN port is configured to be on standby (disabled). For information about configuring the
Ethernet LAN ports in a port redundancy pair,
When Branch Gateway senses that the link is out of service on the primary port or failure of
the switch to which the primary link is attached, it automatically enables the secondary link to
the backup switch. Both the ports must be administratively enabled on their respective LAN
switch peers.

RSTP configuration

Branch Gateway can be deployed in the LAN using RSTP to provide redundancy. Branch
Gateway is connected to an external LAN switch using both the Ethernet LAN ports located
on the Branch Gateway's front panel.
