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 brctl 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
