G'day cisco SMB switchers,
I have run a couple SG300 devices for ~9 months as a test deployment. I have had a majority of the features including ACL working perfectly without issue until now. Presently, my SG300-28 is working however whenever I remove an ACL on vlan 200 to block a couple IPs the switch hangs and requires power-cycling to become responsive again. I have tried multiple times from both the GUI and command line to remove the troublesome ACL, always resulting in a complete hardware hang (no ping, no response).
Curiously, the ACL is related to vlan 200 which is a wireless vlan that has nothing to do with my wired management of the device via vlan 1. Further, the IPs which the offending ACL are related to a network across town accessible via VPN only, so they have nothing to do with my local network. As such, I really don't think I am making a mistake by locking myself out, and think the hardware is problematic. Presently I am using the switch on the edge of my network, and for now it is working as long as I don't delete that offensive ACL.
Normally the next step I would take would be to reload the config from file, then reload the firmware (already latest version, has been working for months as is), and finally google how to hard-reset the switch. But if I were to do so, I would lose trust in the SG300 line, and hesitate to roll it out across networks as I originally planned to do in a few months after completing this testing phase.
Can anybody restore my confidence in the SG300 line, such that we can understand what is wrong, so I can avoid writing off the hardware and trying another solution?
Many thanks,
-Brian
