Packet Voice Processor Commands Manual
6.1.1 Media Interface Features
The Packet Voice Processor Interface Processing cards (see
)
support the following Ethernet interfaces for connection to the RTP media network:
1000Base-T interface (RJ-45 connectors), full duplex
1000Base-LX interface (SC connectors)
1000Base-SX interface (SC connectors)
These interfaces provide the following networking (Layer 2, Layer 3, and Layer 4)
features:
Link Aggregation Control Protocol (LACP) through IEEE 802.3ad, supporting
1 to 8 Link Aggregation Groups (LAGs), and 1:N redundancy
IPv4, UDP, RTP, RTCP support
UDP port number range 10,000-65,535
Configurable for 1 to 8 IP addresses
Support for static IP address configuration
Route discovery for RIP v1 and v2 based route daemon, as well as IRDP
6.2 LAG
Link Aggregation Groups (LAGs) are logical groupings of Gigbit Ethernet ports. Link
aggregation, defined in IEEE standard 802.3ad, is a method where multiple physical
links are combined into a single logical link. This provides the following important
features: increased link capacity and redundancy.
Link aggregation provides both data flow distribution (transmit) from the Packet Voice
Processor and data flow collection (receive) to the Packet Voice Processor. Transmit
and receive data flows occur across the LAG ports within each provisioned LAG.
With an upper bound of four ports (links) in a LAG, link aggregation with Gigabit
Ethernet can provide a single logical link capable of achieving an aggregate
theoretical 4 Gbit/s in each direction with full duplex operation. Link aggregation does
not modify the 802.3 frame structure. Link aggregation is also completely transparent
to all upper-layer protocols. The Packet Voice Processor supports up to four static
LAGs.
6.2.1 LACP
The IEEE standard 802.3ad uses the link aggregation control protocol (LACP) to
automatically establish the link aggregation groups. Once implemented, link
aggregation can be configured and reconfigured quickly and automatically with a low
risk of duplication or reordering of frames.
6.2.2 Static LACP Mode
The Packet Voice Processor supports Static LACP Mode (see
