The external Layer 2 switches should also be configured for VLANs and tagging.

FDB static entries
Static entries in the Forwarding Database (FDB) allow the switch to forward packets without flooding ports to
perform a lookup. A FDB static entry is a MAC address associated with a specific port and VLAN. The switch
supports 128 static entries. Static entries are manually configured, using the /cfg/l2/fdb/static command.
FDB static entries are permanent, so the FDB Aging value does not apply to them. Static entries are manually
added to the FDB, and manually deleted from the FDB.
Incoming frames that contain the static entry as the source MAC can use only ports configured for the static entry.
Trunking support for FDB static entries
A FDB static entry can be added to a port that is a member of a trunk group, as follows:
•
Static (manually configured) trunk group
•
Dynamic (LACP) trunk group
The trunk group supports the FDB static entry. If the port with the static entry fails, other ports in the trunk handle
the traffic. If the port is removed from the trunk, the static entry is removed from the trunk, but remains configured
on the port.
The FDB information commands (/info/l2/fdb) display trunk support for static FDB entries, if applicable:
