Thanks. We will test the 3.7 code branch. I post result here after it is.

Need hardware upgrade? What version of board support SFFD?

Because one of switches not shutdown port when auto negotiation is disabled and one of two fibers damaged.

I want enable SFFD on optical port of 8616SX-E board, but I can’t do it. # config ethernet 3/5 auto-negotiate disable # config ethernet 3/5 sffd enable Error: port 3/5, this hardware does not support SFFD enabling/disabling In Network Design Guidelines I read that it is feature is supported on...

If Netgear switch support STP protocol it must prevent organizing loop when two ports of switch is interconnected. In other case switch not support STP protocol and BPDU can’t flood Ethernet segment. Or STP protocol realization is not correct and STP protocol must be disabled on this switch...

You can reset switch to default configuration if you stack it to other switch, with same firmware version and reset stack to default settings.

You not say me can you manage switch via console port. Try entering menu interface and pinging default gateway. Is it being successful? If it not success, use sniffer on port where exist management VLAN. Can you see BPDU packets, "hello" packets and ARP requests from switch?

Are you losing management via telnet, SNMP, SSH? Can you manage switch at this time via console port?

Are you seeking way to add static route?

Only one IP address can be assigned to Passport in one VLAN. You can use IP address in other IP network/subnetwork.

1200 not support multicast. FLP you must disable IGMP snooping on BayStacks.

I use Device Manager to request CPU load and when its tool sends SNMP request I sniff SNMP packet and decode it by SnifferPro.

Select one switch that always up. Set its switch STP root. After you not have problems with change topology.

I think it’s not correct. Different realization STP can break loop.

You may have this problem if new switch has more priority (MAC address and etc) than existed root. If you set lover priority value of existed root switch its situation may happened only if root switch go down. And plugging to existed network new switch with default values not called rebuilding...
