commands. Note that apart from the management VLAN, which is configured
during initial configuration, the connections are made automatically by the
Public Ethernet Manager (PEM).
4.10.1 Bandwidth Limitation
A bandwidth limitation may be imposed on each connection (ingress and
egress). It is implemented as a bandwidth profile (se set
bandwidth_limitation in section 13.8.8 on page 118), which is then
selected for a specific connection with the connect vlan command (see
section 13.8.6 on page 114. Up to 32 profiles can be used. Eight profiles are
created per default and can be modified.
When a bandwidth limitation profile is applied to a connection it will limit the
following traffic types:
Applied on an Ingress connection: unicast and broadcast packets
Applied on an Egress connection: unicast Multicast and broadcast packets
Unless VLAN per End-user is used, only the connections from the switching
domain to the downlink port should be configured with bandwidth limitation.
That is egress connection for the downstream and ingress for the upstream.
The reason is that these are the only connections that are connected to a
single End-user. The connection from the switching domain will transport
traffic from several End-users and there is therefore no meaning in applying
bandwidth limitation to that connection.
