Cache Locator membership port range 1024–65535

[sathya66]

Hi All,

Opening ports from 0/1024 to 65535 means we are opening everything for inbound and outbound connections .  Is it safe to open to sas Clients as well  or just sas servers ? If we give this range then we can ignore other ports? (ex: metadata ports, compute ports,etc )?

how this works?

Cache Locator membership port range (TCP/UDP port range)1	1024–65535	Inbound and outbound
TCP port for middle-tier cache communications3	0–65535	Inbound and outbound

Opening the required ports would not cause an issue in the SAS installation. During installation one selects the required port number (or the default value).

In any case all ports are not used.

If there is a firewall installed the selected  ports need to be open for communications.
