I love this list, cause it makes me hack a little bit. So if you are on ontap8, bust into systemshell.
There's a cool little command called tcp_client. Using it, to test if 10566 (snapmirror tcp port) is open goes like this.
odin% tcp_client usage: tcp_client my_ip my_port server_ip server_port odin% tcp_client 10.0.0.2 10289 10.0.0.1 10566 ***25 bytes sent server closed odin%
port 22 is specifically not open, so it hung here. And ctrl-c got me out. It may have wanted a lower source port too.
odin% tcp_client 10.0.0.2 10289 10.0.0.1 22
^C odin% man tcp_client man: Command not found. odin% tcp_client -h usage: tcp_client my_ip my_port server_ip server_port odin% tcp_client 10.0.0.2 10289 10.0.0.1 10566 ***25 bytes sent server closed odin%
On the remote side, we see this.

So that seems to be a way to do it. If there's an easier way, let's here it (besides asking the network guys).

If it is an active snapmirror session, then maybe a netstat -a and look for port 10566

I need to check if the firewall is open between filers on snapmirror ports. I cannot find a "telnet" command so I can telnet from fi ler to to filer on specific port. How do I check from filer CMD line if the ports on the snapmirror partner are open Thanks!
