Local Vcs Inbound Ports; Local Vcs Outbound Ports; Remote Listening Ports - Cisco TelePresence Video Communication Server Administrator's Manual

The information can be sorted according to any of the columns on the page, so for example you can
sort the list by IP port, or by IP address.
Each page contains an Export to CSV option. This lets you save the information in a CSV (comma
separated values) format file suitable for opening in a spreadsheet application.
Note that IP ports cannot be configured separately for IPv4 and IPv6 addresses, nor for each of the
two LAN interfaces. In other words, after an IP port has been configured for a particular service, for
example SIP UDP, this will apply to all IP addresses of that service on the VCS. Because the tables
on these pages list all IP ports and all IP addresses, a single IP port may appear on the list up to 4
times, depending on your VCS configuration.
The port information is split into the following pages:

Local VCS inbound ports

n

Local VCS outbound ports

n

Remote listening ports

n
On a VCS Expressway you can also configure the specific listening ports used for firewall traversal by
going to the Ports page (VCS configuration > Expressway >
Further information about ports can be found in the
Local VCS inbound ports
The Local VCS inbound ports page
ports) shows the listening ports on this VCS. These are the IP ports on the VCS used to receive
inbound communications from other systems.
For each port listed on this page, if there is a firewall between the VCS and the source of the inbound
communications, your firewall must allow:
inbound traffic to the IP port on the VCS from the source of the inbound communications, and
n
return traffic from that same VCS IP port back out to the source of the inbound communication.
n
Note: this firewall configuration is particularly important if this VCS is a traversal client or traversal
server, in order for Expressway firewall traversal to function correctly.
Local VCS outbound ports
The Local VCS outbound ports page
outbound ports) shows the source IP ports used by this VCS. These are the IP ports on the VCS
used to send outbound communications to other systems.
For each port listed on this page, if there is a firewall between the VCS and the destination of the
outbound communications, your firewall must allow:
outbound traffic out from the IP port on the VCS to the destination of the outbound communications,
n
and
return traffic from that destination back to the same VCS IP port.
n
Note: this firewall configuration is particularly important if this VCS is a traversal client or traversal
server, in order for Expressway firewall traversal to function correctly.
Remote listening ports
The Remote listening ports page
shows the destination IP addresses and IP ports of remote systems with which the VCS
communicates.
