Bonding multiple NIC's w/ Cisco 3750
I have a new ReadyNAS 4220. I'm trying to bond all 4 1GbE NIC ports to a Cisco 3750G switch. I'm connecting to the management tool via the 10GbE port so the tool connectivity isn't affected by my tw...
If I had to pick a suspect, I would say that you had a VLan mismatch between your Cisco device and your NAS, but as already said, Cisco is pretty much a world of its own and depending on your configuration and the configuration of surrounding devices that could be quite complicated to diagnose. VLan mismatch on the NAS and 3750G interfaces would explain the loss of connectivity (since everything would be isolated at layer 2 of the OSI model, so no DHCP, no IP, no ping...).
I'm no Cisco expert (passed CCNA a few years back but didn't practice until recently with my 20€ 1812 bought in a garage sale) but what I can tell you is that trunk ports are used to let multiple VLANs flow through a single port, typically between switches, or between a switch and a router. Access ports are used otherwise. When in doubt I always let the switch decide the VLAN, it should do the tagging for you and you shouldn't have to set anything on your NAS.
As for the light, that's normal that you got amber light for a second or two, that's the time the Switch took to configure the interface, therefore resulting in a wrong port configuration for a moment.
Anyway, glad you worked it out. You know what we say "in computer science, when things should be working, they usually don't ; and when they work nobody knows why.".
