capable of performing much more sophisticated switching than an ordinary
learning­bridge switch.
In the descriptions in this guide, ‘switching domain’ is used, for the sake of
clarity, instead of the ‘
vlan
’ notation used in the CLI.
4.10 Connections
Ports, switching domains and connections are central concepts for switching in
the EFN324. A port is either an Ethernet port (called
ethernet_port
in the
CLI) or the Host port (called
host_port
in the CLI).
For a packet to travel through the switch, the following two connections must
be defined:

The ingress connection : the connection between the ingress port on
which the packet arrived and a switching domain.

The
egress connection
: the connection between the switching domain
and an egress port.
Figure 10 Ingress and Egress Connections
Even though the 26 Ethernet ports and 200 switching domain resources are,
by default, present from the start, connections must be defined (configured) by
the operator. A connection is created or deleted using the
connect or disconnect
