MSAP2000 AAMS User's Guide
For example, you want to give high priority to voice service on one of the ADSL
ports.
First configure a static VLAN on the MSAP2000 AAMS for voice on the port.
Then do the following:
•
Configure a channel on the port for voice service.
•
Set the channel to use the PVID of the static VLAN you configured.
•
Assign the channel a high priority.
7.8.1 Super Channel
The MSAP2000 AAMS forwards frames belonging to VLAN groups that are not
assigned to specific channels to the super channel. Enable the super channel
option to allow a channel forward frames belonging to multiple VLAN groups
(that are not assigned to other channels). The super channel functions in the
same way as the channel in a single channel environment. One port can have
only one super channel.
7.8.2 LLC
LLC is a type of encapsulation where one VC (Virtual Circuit) carries multiple
protocols with each packet header containing protocol identifying information.
Despite the extra bandwidth and processing overhead, this method may be
advantageous if it is not practical to have a separate VC for each carried protocol,
for example, if charging heavily depends on the number of simultaneous VCs.
7.8.3 VC Mux
VC Mux is a type of encapsulation where, by prior mutual agreement, each
protocol is assigned to a specific virtual circuit, for example, VC1 carries IP, VC2
carries IPX, and so on. VC-based multiplexing may be dominant in environments
where dynamic creation of large numbers of ATM VCs is fast and economical.
7.8.4 Virtual Channel Profile
Virtual channel profiles allow you to configure the virtual channels efficiently. You
can configure all of the virtual channels with the same profile, thus removing the
need to configure the virtual channels one-by-one. You can also change an
individual virtual channel by assigning it a different profile.
The MSAP2000 AAMS provides two default virtual channel profiles: DEFVAL
(for LLC encapsulation) and DEFVAL_VC (for VC encapsulation). By default, all
virtual channels are associated to DEFVAL.
