Can't access BE6k/ESXi from same VLAN

Philip Denton — Tue, 19 Mar 2019 18:33:10 GMT

In order to upload ISOs to my VMWare host I usually traverse a 100Mb switch and an ASA5505. This is painfully slow so I figured that temporarily putting my laptop in the same VLAN/subnet as my VMWare hosts would speed things up since my core switch is 1Gb.

Unfortunately this is only half true. From the same VLAN/subnet I can't access my BE6k at all. No ping, SSH, web, or vSphere. I can upload a 2.5Gb ISO to my first UCS host (of Windows guests) in about 75 seconds. I can also access it via vSphere and web.

Is there some funky network or security setting that is barring direct network access to my BE6k? I can access it via every method when I do it through my firewall but nothing works from the same subnet. I feel like I'm missing something here but the fact that two VMWare boxes with almost identical versions of ESXi running are behaving differently I am led to believe there's a setting in Cisco's stock ESX config that's different.

Any ideas? TLDR: Two VMWare hosts in the same VLAN/subnet. I can reach one but not the other when I put my laptop in the same VLAN. Both are reachable when traversing the firewall.

You may want to check your IP, Subnet, Gateway, and VLAN settings using a VGA monitor and USB keyboard.

Good thinking. I'll check it

Good thinking. I'll check it out tomorrow. Everything is /24 for simplicity's sake but maybe I fat-fingered something.
