It is hard to help you when I miss the step by step answers to my proposed test scenario in #7 post. I only asked for one connection of Eth interface from the NAS to switch - to be clear in the evaluation. When you have seen 2 IP addresses you have connected two interfaces parallelly from the NAS. For this test, it was the wrong attitude.
I'm afraid to ask for more complicated things through SSH because I don't know what I'll get from you.
First, you need to create a fixed address of the switch. It is a must.
Better is to create fixed IP addresses for the NAS also.
Then you can use this test:
- connect NAS with the SINGLE 1G interface ---->> to the switch port No. (1-8)
+ together
- connect NAS with the 10G interface ---->> to the switch port No. 9
+ together
- connect the Mac to the switch, but don't use the external 10G card (one from the ports 1-8)
then Mac terminal:
ssh into the NAS ----->>> ssh user@hostname
where
user is the NAS administrator account
the hostname is IP of the 1G NAS interface .... must be100% sure, when no unplug the 10G interface from NAS and check the NAS IP, then plug-in back the 10G
so the command is like
then psw and:
again the same psw
then copy-paste results here for these commands (in the defined order):
then
Bash:
ifconfig -s -a | grep eth
then little bit complicated (because I don't know how is attached the PCI-e Eth NIC to the system:
where <ethx> = name for each the ethernet interfaces from previous command results, e.g. eth0, or eth1
then
Bash:
ping -I <ethx> -a -c 4 <IPadressoftheSwitch>
>
e.g. 'ping -I eth0 -a -c 4 192:168:1:104'. Be sure, that the IP address is 1000000% the IP address of your switch
repeated it for each the <ethx> interface ..... eth0, eth1, ....
same pings to your Mac IP address
When you are lost, open a beer and be lucky for other things in your life.
