FDB Update
Use the FDB update option to notify other devices on the network about updates to the Forwarding
Database (FDB). When you enable FDB update (/cfg/l2/hotlinks/sndfdb ena), the
switch sends multicasts of addresses in the forwarding database (FDB) over the active interface, so
that other devices on the network can learn the new path. The Hot Links FBD update option uses the
station update rate (/cfg/l2/update <packets per second>) to determine the rate at which to
send FDB packets.
Configuration Guidelines
The following configuration guidelines apply to Hot links:
Only uplink ports and inter-switch links can be configured as Hot Links.
Ports that are configured as Hot Link interfaces must have STP disabled.
When Hot Links is turned on, MSTP, RSTP, and PVRST must be turned off
(/cfg/l2/mrst/off).
When Hot Links is turned on, UplinkFast must be disabled (/cfg/l2/upfast d).
A port that is a member of the Master interface cannot be a member of the Backup interface. A
port that is a member of one Hot Links trigger cannot be a member of another Hot Links
trigger.
An individual port that is configured as a Hot Link interface cannot be a member of a trunk.
Configuring Hot Links
Use the following CLI commands to configure Hot Links.
>> # /cfg/l2/hotlink/trigger 1 ena (Enable Hot Links Trigger 1)
>> Trigger 1# master/port 20 (Add port to Master interface)
>> Master# ../backup/port 21 (Add port to Backup interface)
>> Backup# ../..
>> Hot Links# on (Turn on Hot Links)
>> Hot Links# apply (Make your changes active)
>> Hot Links# save (Save for restore after reboot)
