UDP port number for UDT traffic?
Does anyone know what UDP port number is used by VPLEX WAN COM over IP (UDT) traffic?

Actually, the default port is 11000. See the IP WAN COM spreadsheet (IPComConfigWorksheet_v6.12.xls) on support.emc.com. Access to the file is limited, however. Port 11000 is the default, but can be changed when the IP WAN COM is configured. This port must be open end to end between VPLEX clusters for the WAN COM links.
Also, locally at each cluster, port 10000 is for multi-cast discovery between local directors within each site.
I hope this helps.

Hello there,
VPLEX uses standard UDP for the WAN communication. There is no proprietary port. If you are looking to understand the firewall settings then any firewall would provide a standard UDP setting which is for the opening of the range as determined by the standard. In order to lock down a UDP firewall rule granularly you would need to determine the source and target IP addresses. Other than that, it should just be straight forward settings.

Great catch Andrew. In general, most customers firewall port settings are wide open to hit the standard UDP ports. There are many within the range allocated for the protocol that covers many applications.

UDP, like TCP, has tens of thousands of ports that can be opened for various types of traffic. For example, NTP uses UDP port 123. My question is, what UDP port or ports does VPLEX UDT traffic use? I am not aware of a "standard" port for UDT traffic, but if there is one, can you please share? Thanks!

Hi there,
You are correct, there is no standard port for UDT. It rides over UDP.

Thanks Andrew! That is exactly what I needed!

You can view the port numbers by utilizing the VPLEX CLI and looking at the /clusters/cluster-X/cluster-connectivity contenxt:
VPlexcli:/> ls -l /clusters/cluster-1/cluster-connectivity
/clusters/cluster-1/cluster-connectivity:
Attributes:
Name Value
---------------------------------- --------------------------------------------
discovery-address 224.100.100.100
discovery-port 10000
listening-port 11000
remote-cluster-addresses cluster-2 [192.168.11.251:11000, 10.6.11.251:11000]
