CHAPTER 41
Port Protection Switching
Port protection switching creates a protection path for traffic in case the working path fails.
41.1 Uplink Port Protection Switching
The uplink port protection switching feature creates a working path (active port) and backup path
(backup port) for uplink traffic.
Use uplink protection groups to have active and backup uplink ports. You put 2 uplink ports into a
protection group. There are 2 groups for the 4 uplink ports. Each group has an active port and a
backup port. Normally, the uplink traffic uses the working path (traffic is sent out the active port).
When the active port is down, the OLT sends out packets using the backup path (traffic is sent out
the backup port). You assign downlink (Gigabit Ethernet or PON) access ports for each protection
group. Assign specific Gigabit Ethernet or PON ports to a protection group to group services or
users and separate them from the services and users in other protection groups.
Figure 64 Uplink Port Protection Switching
You can also use a command to change the current active port.
The following section lists the commands for this feature.
