capturing 100Mbps traffic with ms-dos Sniffer 5.09c for Ethernet IV

[gfernval]

Hello:

Finally, with the Cogent EM110 TX PCI card, the Sniffer 5.09c for the Ethernet IV (Cogent card) can capture 100Mbps traffic, but oddly, the Adaptec ANA-6911/UC can capture only traffic at 10Mbps. The differences between Cogent EM110 TX and Adaptec ANA-6911/UC are only that the Adaptec card has AUI and BNC connectors in addition of RJ45 connector both cards have. Is possible to convert an Adaptec ANA-6911/UC card to behave exactly like the Cogent EM110 TX card in order to capture at 100Mbps? Both cards are from Network General (MAC address: 000065xxxxxx)

thanks

I can't recall seeing a 100mb NIC with BNC and AUI ports.

In BNC and AUI ports, the capture is at 10Mbps only, but in RJ45 the capture can be at 100Mbps. The problem with the Adaptec ANA-6911/UC card is that only captures traffic at 10Mbps in the RJ45 connector with Sniffer 5.09c for the Ethernet IV, regardless I specify 100 TX in the capture options. This matter doesn´t occur in the Cogent EM110 TX PCI card (only has an RJ45 connector, no BNC or AUI connectors)
I would like to know how to convert an Adaptec ANA-6911/UC card to behave exactly like a Cogent EM110 TX card, so I can capture traffic in the RJ45 port of the Adaptec ANA-6911/UC card at 100Mbps
