Figure 4-10 Fast Path operation overview
Fast Path Configuration
Fast Path is enabled from the Advanced Redundancy tab in NCU by checking the Fast Path
Failover checkbox (refer to Figure 4-11). Fast Path can also be monitored from the Advanced
Redundancy tab. Under the Team Members section, the Port/Path Cost column provides real-time
monitoring information. The Port Cost value (in other words, 4 in Figure 4-11) is the Spanning
Tree cost associated with the current speed of the teamed port. Fast Path uses IEEE 802.1D
guidelines for assigning costs based on the operating speed of teamed ports. For example, 4
would indicate the individual teamed port is running at 1000 Mbps, 19 would indicate 100 Mbps,
and 100 would indicate 10 Mbps. The Path Cost (in other words, 27 or 8 in Figure 4-11) indicates
the individual teamed port's full Path Cost from the teamed port itself all the way to the root
switch. The monitoring information displayed in Figure 4-11 would be the results of the network
configuration described in Figure 4-10.
