-- asa 5510 bandwidth question

Hi all,

We have a symetric 10 Mb line. But input is not more than 3 Mb, output is for sure around 10 Mb...

I am trying to identify the bottleneck of it. I put everything in 100FD. Even the switch to which the asa is connected to.

When i use the command "sh int", i have the following:

Interface Ethernet0/0 "inside", is up, line protocol is up

Hardware is i82546GB rev03, BW 100 Mbps, DLY 100 usec

Full-Duplex(Half-duplex), 100 Mbps(100 Mbps)

Interface Ethernet0/1 "outside", is up, line protocol is up

Hardware is i82546GB rev03, BW 100 Mbps, DLY 100 usec

Full-Duplex(Half-duplex), 100 Mbps(100 Mbps)

I am wondering why it Full-Duplex(Half-duplex) and not only Full-Duplex ?

Btw, if anyone know a good tool to measure bandwidth, it could be great 😉

Thanks,Regards,

The full-duplex(half duplex) issue is because you got 1 side in auto-negociation a 1 side is forced. In this case, the link will go into half duplex.

For your measuring needs, I would do it with good old wireshark sniffer. You capture the trafic and use the statistic feature.

If you got a router supporting netflow in you path, this would also work realy good.
