If I understand your question correctly you are looking for the
IfIndex of an interface:

Switch> show port 3/1
Port  Name               Status     Vlan       Level  Duplex Speed Type
----- ------------------ ---------- ---------- ------ ------ ----- ------------
 3/1  AK                 connected  10         normal   half    10 10BaseFL MM

Port  Security Secure-Src-Addr   Last-Src-Addr     Shutdown Trap     IfIndex
----- -------- ----------------- ----------------- -------- -------- -------
 3/1  disabled                                     No       disabled 10     
                                                                     XX
                                                  This is what you need.

Alternatively "show port ifindex" will give you the list:

Switch> show port ifindex

Port   ifIndex
-----  -------
 1/1   3
 1/2   4
 2/1   22
 2/2   23
 2/3   24
 2/4   25
[...]
