Port redundancy overview
Redundancy involves the duplication of devices, services, or connections, so, in the event of a failure, the
redundant duplicate can take over for the one that failed.
Since computer networks are critical for business operations, it is vital to ensure that the network
continues to function even if a piece of equipment fails. Even the most reliable equipment might fail on
occasion, but a redundant component can ensure that the network continues to operate despite such
failure.
To achieve port redundancy, you can define a redundancy relationship between any two ports in a switch.
One port is defined as the primary port and the other as the secondary port. If the primary port fails, the
secondary port takes over.
You can configure up to 25 pairs of ports per chassis. Each pair contains a primary and secondary port.
You can configure any type of Ethernet port to be redundant to any other. You can configure redundant
ports from among the Ethernet LAN port on the G350 front panel and the Ethernet ports (1-24) and the
Gigabit Ethernet port (51) on the MM314 Media Module.
