Verifying the forwarding database

To view all instances of the forwarding database (FDB), use the following CLI command:

diagnose netlink brctl list

Example

FGT # diagnose netlink brctl list

list bridge information

1. root.b fdb: size=256 used=6 num=7 depth=2 simple=no

2. mgmt.b fdb: size=256 used=5 num=4 depth=2 simple=no

Total 2 bridges

Here above we can see two bridge instances for 2 VDOMs in transparent mode: root and mgmt.

• This command will dump the L2 forwarding table for each VDOM bridge instance:

diagnose netlink brct1 name host <VDOM_name>.b

Example for the root VDOM:

FGT# diag netlink brctl name host root.b

show bridge control interface root.b host.

fdb: size=256, used=6, num=7, depth=2, simple=no

Bridge root.b host table
