6.2.4 LAG Provisioning - Network Elements
Table 6-2 describes the network elements that may be required for a Packet Voice
Processor network configuration using LAGs. Use this table when first planning to
incorporate a Packet Voice Processor within your network.
Note Figure 6-2 on page 63 displays an example of how the network elements described
in Table 6-2 connect and operate in an IP network.
Table 6-2 PVP Network Elements
Network Element Description
Packet Voice Processor System The Packet Voice Processor uses Link Aggregation Groups
(LAGs) to increase media (bearer) traffic capacity and for
redundancy purposes. The Packet Voice Processor supports up
to 4 separate LAGs.
Each LAG can support the following features:
• IP address - Maximum of 4 IP addresses
• UDP Port Numbers - Minimum range of 10000
• UDP Port Numbers - Maximum range of 65535
• LACP Mode - Static
• Total LAG ports - Maximum number of 4 ports
Switch Router or Routers -
For the Signaling IP network.
The Packet Voice Processor supports the SIP signaling protocol.
A Packet Voice Processor network configuration requires a router
or routers for SIP signaling. Note that a single router can be used
for both SIP signaling and Packet Voice Processor system
management or voice bearer traffic.
The Packet Voice Processor requires at least 1 network interface
(IP address) for signaling purposes.
Switch Router or Routers -
For the Management IP network.
A Packet Voice Processor network configuration may require a
router or routers for Packet Voice Processor system
management. Note that a single router can be used for both
Packet Voice Processor system management and SIP signaling.
The Packet Voice Processor requires 1 network interface (IP
address) for system management.
Switch Router or Routers -
For the Voice Bearer (Media) IP
network.
The following configuration is recommended for the voice bearer
(media) IP network:
• VLAN/IP subnet: Packet Voice Processor LAG (IP interface)
• RIP – Routing Information Protocol (RIP) is preferred, but not
required. If RIP is not enabled, user adds a default route using
the CLI.
• IRDP/IGMP – ICMP Router Discovery Protocol (IRDP) or Inter-
net Group Management Protocol (IGMP) for route discovery
(optional)
• LACP – Link Aggregation Control Protocol (LACP) For link pro-
tection (optional) or equivalent link aggregation capability.
• HSRP/VRRP – Hot Standby Router Protocol (HSRP) or Virtual
Router Redundancy Protocol (VRRP) for router fail-over
(optional)
Note that a single router can be used for both the bearer (media)
IP network and SIP signaling.
SIP Proxy and/or Session Border
Controller (SBC) The SIP proxy and/or Session Border Controller must be
connected to the signaling networks and reachable by the Packet
Voice Processor.
FTP/TFTP Server The FTP/TFTP server is used for software upgrades and must be
connected to the management IP network, as well as reachable
by the Packet Voice Processor.
