Please excuse my newness. This is my new lab environment where I'm trying to teach myself UCS. Problem: I've created a port-channel in UCSM (on a standalone 6248up, firmware 2.2(3f)) and connected it to my 2960 switch, but I'm only seeing multicast t...

In my lab environment, I tried connecting the 10Gb Cisco transceivers that came with my 6248, to ports to be used as uplinks to my 2960-S (because I'm trying to use my current infrastructure, instead of putting in an extender and moving all my equipm...

The UCS drives I have are firmware A005 since we keep them updated with HUU as recommended. The UCS-C22-M3 requires a 9240-8i for ESXi to be able to be installed. We are trying to find an actual use for it. The 9240-8i requires firmware A001 to be on...

So I got a hand me down UCS-C22-M3 with 96Gb ram, dual 8 core processors, and 8 300Gb hard drives. It won't run ESX because it only has software RAID. You can't even see the hard drives to boot from them during startup. Software RAID sees the drives ...

Perhaps I've never noticed before and they are always like this, but do the 5548UP switches run hot (50+C) and with fans at full speed by design (seems extraordinarily power inefficient), or is there some performance tweaking that needs to be done to...

To identify the core of the problem - the Native VLAN box was not checked in my vNIC configuration for the interface in the Service Profile, so everything was being tagged to VLAN 1. So, while changing the VLAN of the management interface of the ESXi...

Your comment below made me think to check the mac address-table on the FI:"As the default native untagged vlan on a Cisco switch is vlan1 do you also have a untagged vlan 1 on the server and are the vnics assigned to vlan 101"When I checked it, I onl...

I tried pinning the vNIC to the port-channel in question, and it appears to have had no effect. I think this is because that was the only port-channel on the system which is used to connect upstream, and the UCS switch would have automatically used t...

The ESXi server is installed on a B440 blade in a UCS 5108 chassis. I did create vlan 101 in UCSM, and applied it to the vNIC's that are on the VMware service profile for the blade. The vlans should be transparent to the guest on the blade. My only q...

There is no vpc command in the port-channel interface configuration mode.I removed both Gb ports and the po1 from specifically allowing vlan 101 in the trunk, and also blocked the BPDU's with the commands you suggested (except for port type edge trun...
