It is also possible to stop an egress connection from sending broadcast
packets, by setting ‘broadcast_allowed’ in the egress connection to
false
.
Broadcast packets are thereby totally eliminated on that connection.
5.4 Egress Connection Functions
The egress connection functions are illustrated in Figure 19 on page 38.
Figure 19 Detailed Path from Switching Domain to Egress Port
When the switching domain has decided to forward a packet on an egress
connection, the following steps are performed before the packet is sent out on
the egress port:
1. Quality of Service
Quality of Service functions are performed, as described in section 5.5.2
on page 43.
2.
VLAN Tagging
The packet is provided with the VLAN Tag, or tags, defined for the egress
connection. Note that the outgoing packets may be ‘untagged’ so that the
tags, if any, in incoming packets are removed. The outgoing packet is
either untagged, single tagged or double tagged (QinQ).
Configuring VLAN IDs to be handled as transparent is possible, and as a
result, the VLAN IDs will not be changed.
3.
Priority Based Queuing and Traffic Scheduling
Priority based queuing and traffic scheduling functions are performed, as
described in section 5.5.2 on page 43.
