Hello Community,
I tried to describe my issue through the title of this discussion. I have a problem in regards to the connection between the MDS Switches and Nexus Switches at a Customers Data Center. So far we have configured our Ports in this way:
1) Nexus is in NPV Mode, port to MDS is in NP Mode, Trunking is off
2) MDS is in its Default Mode(IDK what it's called, sorry), I have zones configured in it, and the port to the Nexus Switch is configured as an F port, with trunking off.
Normally in this case the Nexus Switch should get the WWNs from all the Hosts and Storages "advertised" through it's NP port, but it's seeing none of them. Here is the show interface command:
MDS:
Hardware is Fibre Channel, SFP is short wave laser w/o OFC (SN)
Port WWN is 20:02:00:3a:9c:ca:44:e0

----------------------------------------------
On the MDS Side, I can see the pWWN of the Nexus Switch, but the Nexus Switch isn't even seeing the MDS. Do you guys have had any experience like this and how can I solve it?

Is NPIV enabled on MDS?
switch(config)# npiv enable

I enabled the feature through: feature npiv
I will check for the npiv enable command, if that is necessary too and I'll reply if that solved the problem.
