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.
Secondary port activation
The secondary port takes over within one second and is activated when the primary port link
stops functioning. Subsequent switchovers take place after the minimum time between
switchovers has elapsed. To set the minimum time between switchovers, use the set port
redundancy-intervals command.
