The EX12 is a packet broker designed to have a good price versus performance ratio because the EX12 supports 12 x 10 Gbit interfaces and a combination of 8 native copper or 8 SFP interfaces for Gbit. As usual non-blocking design and thousands of filters are possible without impacting the function.
A bypass is a hardware device that provides a fail-safe access port for an in-line active security appliance. EX12 monitors the health of the active, in-line appliance by sending heartbeats to the in-line security appliance. As long as the in band security appliance is on-line, the heartbeat packets will be returned to the EX12, and the link traffic will continue to flow through the in-line security appliance. This function also works on the copper ports with a copper hardware switch. It allows the in-line appliance to be removed or serviced without impacting network traffic.
