If the sustained, combined data rate of send + receive data is greater than 1000Mbps, the SharkTap will not be able to duplicate all packets to the TAP port, so some packets can be dropped. On linux it's generally the rx-all option in ethtool. But note, not all NIC cards will accept bad packets, and/or you may have As above, the SharkTap does not care about packet format. Will the SharkTap show packets with bad FCS? This is done for all four pairs, so all standard PoE techniques are supported. So the high speed data is blocked, but DC power is passed through. The center tap of of the isolation transformers for each pair are connected to the corresponding center tap of the other NETWORK port. The SharkTapBYP model provides power-fail bypassĭoes the SharkTap support Power over Ethernet? Yes - if the SharkTap loses power, the Network link will stop working.The SharkTap needs to look for the SFD nibble in the preamble to get byte alignment on 10 and 100Base-T, but beyond that the SharkTap completely ignores Everything between idle line and the next idle is considered a packet. The SharkTap doesn't respond to any kind of packet. The SharkTap has a 64KB buffer to absorb bursts of full duplex traffic.ĭoes the SharkTap respond to flow control packets? If two packets are received at the same time they will be duplicated sequentially on the tap port. Yes, the SharkTap will 'aggregate' packets from the two NETWORK ports and mirror (i.e.
