3. CLI Commands
CLI System Name is identified with the first 32 characters of the SNMP MIB-II OID
sysName. Configuration of sysName via SNMP changes the CLI command
prompt.
Port Configuration
The remainder of SET commands apply to each port within the IP DSLAM or Micro
DSLAM individually and may be configured independently for each subscriber line
(if so desired).
Backbone-VLAN
A Backbone-VLAN tag is the primary packet identifier. It allows a router with
backbone capabilities to make smarter decisions in directing unlearned traffic, by
pointing packets to the correct network clouds. Once the packets have made it to
the proper network, standard VLAN tags direct the packets to the intended ports.

Transmitted in accordance with standard VLAN rules
(see
VLAN Range
on page 3-10). If the packet adheres
to standard VLAN rules and the Backbone-VLAN is
currently configured, then a Backbone-VLAN tag will
automatically be added to the packet, prior to
transmission, along with the configured VLAN ID,
configured Priority and a zero [0] CFI bit.
Dropped if the Backbone-VLAN is not currently
configured, or if the Backbone-VLAN is configured but
the packet's Backbone-VLAN tag does not match the
current configuration. If the packet's Backbone-VLAN
tag DOES match the current configuration, the packet
will follow standard VLAN rules.
Dropped, if the Backbone-VLAN is currently configured.
If the Backbone-VLAN is NOT currently configured, then
