Implement QoS in IP networks 131
Internet Protocols and ports used by IP Trunk 3.01 (and later)
The following IP applications and protocols are used by IP Trunk 3.01 (and
later) and must be transmitted across the customer’s intranet by all IP
routers and other network equipment. This information should be validated
and included in the IP Trunk 3.01 (and later) network engineering guidelines.
Customers using firewalls must be aware of all UDP and TCP ports being
used by IP Trunk 3.01 (and later) and provision their equipment accordingly.
IP Trunk 3.01 (and later) management protocols
IP Trunk 3.01 (and later) uses the UDP and TCP port numbers for
SNMP, Telnet, and FTP (the default port numbers for these common IP
applications).
IP Trunk 3.01 (and later) management LAN ports
In addition to the TCP and UDP ports used for standard IP applications,
there are IP trunk-specific ports used. Messages sent between the DCHIP
Leader card and other cards use TCP port 6001. When the Backup Leader
card and the Follower cards boot up, they obtain their IP address from the
Leader card over UDP ports 67 – 68.
IP Trunk 3.01 (and later) H.323 Voice Gateway Protocols
H.225 Call Setup Signaling uses TCP port 1720 for the destination port.
H.323 Register and Admission Signaling (RAS) uses UDP port 1719. RAS
is used when registering with a Signaling Server Gatekeeper.
Realtime Transport Protocol (RTP) uses UDP port 2300-2363 by default. In
TM 3.1, RTP can also be provisioned to use UDP port 17301 – 17362.
The option is also available to manually enter the starting value for the RTP
port range in TM 3.1. This should only be done at the request of a field
engineer.
IP Trunk 3.01 (and later) Voice Gateway Protocols
On the TLAN subnet, IP trunk cards within a node use UDP ports 2001 –
2002 for inter-card communication.
When using the dialing plan tables to resolve an address for non-call
associated signaling, Nortel MCDN messages use UDP port 15000 on the
TLAN subnet to communicate with cards on the far end of the network.
IP Trunk 3.01 QoS Network Probing Proprietary Protocol
QoS probing uses UDP port 5000.
