I'd like to know how much a lan interface is used? that's mean how much MB by second ?

Try netstat or nfstat

There are other tools like NetMetrix or a LAN analyzer to watch lan performance.

If you have it you could run glance and select the network screen (i.e. "l" key).

If you lack glance you could read the NICs octet counters, say every 5 minutes and run something like this (this queries lan0 MIB stats):

$ /usr/sbin/lanadmin -g mibstats 0|awk -F' = ' '$1~/(Inbound|Outbound) Octets/{print$2}'

At each run subtract the counts from your last query from the current counts.
Multiply result by 8, and divide by your query interval in secs (viz. 300).
Further devision by 10^6 should give a rough approximation to throughput in Mbit/s.
If you don't want to distinguish in- and outgress just add octet counters for in and out.

You should use a software like MRTG, http://oss.oetiker.ch/mrtg/
That one is nice :).
