Trigger Failover Configuration
This chapter contains Trigger Failover (TFO) configuration examples.
This example shows the complete configuration to enable TFO in a simple network topology. TFO complements NIC teaming functionality supported on blade servers. TFO allows a switch module to monitor specific uplink ports to detect link failures. When the switch module detects a link failure, it disables the corresponding downlink ports automatically.
TFO uses these components:
• A Fail Over Group (FOG) contains a Monitor Port Group (MPG) and a Control Port Group (CPG).
• An MPG contains only uplink ports.
• A CPG contains only downlink ports.
Note:
• TFO is supported in STP or RSTP bridge mode.
• TFO can be configured on a LAG interface.
