Port Utilization Table Column Definition
The columns in the Port Utilization tables in this document describe the following:
•
Protocol. A value representing a formal description of rules to follow and messages to be used by two or more systems to
exchange information. The protocol is also used to communicate with an application or service listening to or connecting
to a remote device.
exchange information. The protocol is also used to communicate with an application or service listening to or connecting
to a remote device.
•
Port. A numeric identifier the Internet transport protocol uses to distinguish among multiple, simultaneous connections to
a single destination host.
a single destination host.
•
Remote Source Port. An identifier—usually dynamic—for the port the remote application or service uses to connect to the
local destination port.
local destination port.
•
Destination Port. An identifier for the TCP or UDP port that the local service or application is listening on, along with the
IP address for incoming connection requests when acting as a server.
IP address for incoming connection requests when acting as a server.
•
Remote Device Destination Port. The identifier for the TCP or UDP port that the remote device’s service or application is
listening on, along with the IP address for incoming connection requests when acting as the server.
listening on, along with the IP address for incoming connection requests when acting as the server.
•
Remote Device. The remote application or device making a connection to the server or service specified by the protocol.
Note
When accessing the Real Time Reporting (RTR) Client on CRS using a browser, the following occurs: The client will
initially communicate to CRS via the pre-configured RMI Port (1099). The CRS server side OS will then determine
what port out of the Ephemeral port range will be used. These have traditionally been between 1024 and 4999 for the
Windows OS. Ephemeral (Dynamic) port range for OS 2000.2.7 and beyond has been changed to 49152 – 65534. This
change was implemented to prevent ports used by Cisco IP Telephony applications from being dynamically assigned
and to bring the OS in alignment with the IANA recommendations. These additional ports have been reserved for
compatibility with some Cisco IP Telephony applications: 57606, 59000-59100, 63432. Previous OS versions used the
Windows 2000 default of 1024 - 4999.
