Could someone check this configuration please?
I have 3 Procurve switches each connected to each other to form a redundant loop.
Everything appears to work however I'm seeing some funny stuff going on with arp caching and vsphere if I pull a switch to simulate a failure.
I'd really appreciate a sanity check that I'm not doing something stupid with the switch configuration.
All I need is a VLAN (100 in this instance) for iSCSI that is tagged/trunked so it spans all the switches.

Hi,
Could you confirm what ports your switches are interlinked on?
Also, it's generally a good idea to tag vlans on switch-switch links and use untagged ports for just access ports.

Re: Could someone check this configuration please?
Ok, well that looks fine as far as connectivity on VLAN 100 goes. Obviously you haven't got the same redundancy setup for VLAN 1.
When you say "pull a switch" are you powering off a whole switch or simulating a link failure?
What is the odd behaviour you experience?
