How to find out the actual speed of an interface?

I'm learning the metric values for EIGRP. Among 5 of the, Bandwidth and Delay are static. For smart serial cables between routers, it defaults at 1554 Kbits I always wondered how fast is the smart serial cable I used between routers. Is there a way for me to measure the real speed of the smart serial cable?

    Also, doing some labbing last night I ran a speedtest with different clock rates on wic2t card, got the following results

    LA test - clock set to 250000
    download speed 217 kb/sec
    upload speed 238 kb/sec


    la test - clock set to 800000
    698 kb/sec down
    763 kb/sec up

    I believe a serial cable will support up to 2 Mbps (E1 Speed).

    [EDIT] try typing "clock rate ?" in interface configuration mode. It should tell you what clock rates are supported. Use the highest one and see if it works and what speed you get.
