Ok, so I just received some 9348 switches. Since that product is NX-OS based; I wondered (without looking at the support chart FIRST) if they supported FEX's; since the NX-OS versions one can run on them do. And since they have 4 SFP+ and 2 QSFP po...
I want to create a double layered vpc environment using 9336c-fx2 switches running nx-os 9.x. According to some doc I've seen; each vpc switch pair's vdc id needs to be unique in the network.By default; the id seems to be 1. Is it possible to chang...
I've looked; but documentation on this isn't exactly clear.I read where a Cisco device running IOS can function as a DNS forwarder - ie not resolving the name/IP relationship itself; but passing it on to the "real" nameservers and relaying the respon...
Nexus 9k 9336C-FX2 running nx-os 9.3.5. Upon upgrade from nx-os 9.2.2; I immediately began getting messages about mac learning being disabled on the native vlan (which is distributed world-wide over thousands of switches) due to "to many mac moves"....
Ok, so I wanted to set up multi-homed active/active FEX connections which apparently came out in nx-os 9.3.5. At the previous 9.2 level; I had no bpdu issues on my FEX's; since while one cannot disable bpdu guard on FEX ports; bpdu filtering takes c...
Sergio, Sorry this is soooo late. For some odd reason I missed the notification of your reply. ALL 2xxx versions of FEX hardware get their operating firmware via download from the parent switch. Which is NX-OS based in my case. So; yes; one *c...
Well, first of all allegedly this *shouldn't* be working *at all* according to the documentation. The FEX support matrix says connection to a Nexus 9348 switch is not supported. Yet one can configure one; and from all show command output; it's work...
Additional info: https://www.letsconfig.com/how-to-configure-double-sided-vpc-in-cisco-nexus/"For second peer of vPC, we are choosing N7K-03 as primary and N7K-04 as secondary. Here note that, vPC domain id needed to be unique, which means you can ...
I've found differing information in the various manuals and articles too. I don't use those switches in ACI mode; and I generally use ports 32-36 as uplinks or VPC connections; but on the rest breakout seems to work. At least for 4 10G breakouts; a...
Apparently you can't. Or; for that matter; for the entire switch until nxos 10. Just another of those things that would have been really useful in the initial nxos release that Cisco apparently overlooked.
