Model 58000 Switch Operation

Figure 2-10. Redundant connections of different community switches to two
Ethernet segments
In Figure 2-10 , the switches are not connected by a trunk link. This means that
each switch is part of a different switch community; therefore, the switches do
not share community management information and network traffic.
Ports 1 through 3 are configured to operate in feeder mode and are all part of
the same virtual LAN. Switch ports 1 and 3 in community 1 are designated
active feeder ports, and switch port 2 is designated a standby feeder port.
Switch port 1 in community 2 is designated the active feeder port, and switch
ports 2 and 3 are standby feeder ports.
If an active feeder port or an active feeder link on a switch fails, the active
feeder port is partitioned and the standby feeder port is enabled. The newly
enabled port resumes communications between the switch and the active
devices on the connected Ethernet segment until the partitioned port
reestablishes connection.
