Rama,
From my experience on Sup-7E, if you use a one-gig transceiver in the supervisor, the port numbering stays the same. Kind of confusing but at least it's consistent! Example below:
Switch>show inter status mod 5
Port Name Status Vlan Duplex Speed Type
Te5/1 connected trunk full 10G 10GBase-SR
Te5/2 connected trunk full a-1000 1000BaseSX
Te5/3 inactive 1 full auto No XCVR
Te5/4 inactive 1 full auto No XCVR
Switch>
Does this answer your question?
