vpn tunnel overutilized?

I have an ASA 5500X series and the IT admin said that his data replication from his NAS only shows 2Mbps. She is doing the replication from one NAS to another via VPN. She said that the issue is from the VPN connection. Is there any Cisco commands that I can use to investigate to see of her claim is true? Thx

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

it may well be that the replication is as fast as 2Mbps. ASA will only slow down a little bit due to vpn encryption.
Please note that during the transfer one site use download data rate and the other use upload data rate: the bottleneck being of course the slowest data rate (which will probably be the upload).
First thing you need to know is what ISP data line you're using, e.g. what is the ISP provided bandwidth both in download than upload. Chances are that you have an upload guaranteed bandwidth of 2Mbps, which matches exactly with the one measured.
After checking that, you may go to ASDM ASA interface and look into bandwidth usage
hope this helps

Both side speed is 100Mbps download / 50Mbps upload.
50Mbps guaranteed or maximum bandwidth ?

I believe it is max bandwidth
well, then check for guaranteed, and do some speed test over the internet, by checking actual upload speed

any chance the storage admin means 2MBps? with the max of 50mbps (6.25MBps) that puts us much closer than 2mbps
leblancAccountingAuthor Commented:
no he said that it is 2mbps. I am looking for some commands on the ASA to check for utilization of the tunnel.
leblancAccountingAuthor Commented:
My question was: is there any commands on the ASA to check the stats concerning the VPN usage?
not much indeed.
The only thing you maght do is to use:
sh vpn-sessiondb full l2l
and do an average among
Duration: |  Bytes Tx: | Bytes Rx:
and then match another measure taken from data lines by uploading/downloading big files between the 2 sites.
You may find out that it is nearly the same, which means that the problem is in data line bandwith and not ASA.

hope this helps
