Configuring port redundancyConfiguring port redundancyThis section contains information about port redundancy configuration on G350 switch portsand includes the following topics:●●●●●Port redundancy overview — an overview of port redundancy on the G350Secondary port activation — a description of how the secondary port is activatedSwitchback — a description of how switchback occursPort redundancy CLI commands — a list and description of the CLI commands used toconfigure port redundancyPort redundancy configuration examples — examples of port redundancy configurationsPort redundancy overviewRedundancy involves the duplication of devices, services, or connections, so, in the event of afailure, 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 thenetwork continues to function even if a piece of equipment fails. Even the most reliableequipment might fail on occasion, but a redundant component can ensure that the networkcontinues to operate despite such failure.To achieve port redundancy, you can define a redundancy relationship between any two ports ina switch. One port is defined as the primary port and the other as the secondary port. If theprimary port fails, the secondary port takes over.You can configure up to 25 pairs of ports per chassis. Each pair contains a primary andsecondary port. You can configure any type of Ethernet port to be redundant to any other. Youcan configure redundant ports from among the Ethernet LAN port on the G350 front panel andthe Ethernet ports (1-24) and the Gigabit Ethernet port (51) on the MM314 Media Module.Secondary port activationThe secondary port takes over within one second and is activated when the primary port linkstops functioning. Subsequent switchovers take place after the minimum time betweenswitchovers has elapsed. To set the minimum time between switchovers, use the set portredundancy-intervals command.Issue 3 January 2005 139
