In order to achieve a high Quality of Service (voice quality/real time behavior of
signaling), the support of IEEE 802.1 p/q VLAN Tagging and IETF RFC 2474
DiffServ is recommended (see
IMPORTANT: If an access point is connected over Wide Area Networks in which
the available bandwidth is extremely restricted, the control information
(signaling) and voice data (payload) for access points must be given priority over
other services.
Frequently, only explicitly familiar TCP/IP or UDP/IP port numbers are supported
in the customer LAN for security reasons. All others are then blocked in such
cases. Precisely which port numbers must be supported for the HiPath HG 3500
component in the network is described in
This feature is used to configure additional nodes/IP gateways in the customer
LAN. Every node/IP gateway requires configuration data which must be
coordinated with the network administration of the customer, documented and
configured precisely as agreed.
The following data must be specified for every new node/IP gateway in the
customer LAN:
• IP address of the node
• Netmask for the network in which the new node is added
• Default router via which the other networks can be reached
Furthermore, the way in which Quality of Service is supported must be clarified
for all networks in which HiPath 4000 components are installed. As HiPath 4000
supports IP distributed architecture processes for controlling the Quality of
Service in a network on various protocol layers, the following must be clarified:
• Is IEEE 802.1 p/q VLAN Tagging (Layer 2) supported?
To this end, it is crucial that all network components with which a HiPath 4000
component communicates must support the standard and be configured
accordingly. If the network contains nodes (particularly switches and routers)
which do not support IEEE 802.1 p/q, VLAN tagging must remain deactivated.
The traffic type is assigned a fixed priority value.
• If DiffServ pursuant to RFC 2474 is supported, which CodePoints can be
utilized?
