I do not know the details of using tcindex to setup queuing.  Take a look
at:

http://www.opalsoft.net/qos/DS-210.htm

... for more info.

As for using exp2tc and tc2exp ...

Here is how to use exp2tc, directly translating EXP bits to TCINDEX:

mplsadm2 -A -I gen:16:0
mplsadm2 -I gen:16:0 -i exp2tc:0x0:0x0:0x1:0x1:0x2:0x2:0x3:0x3:0x4:0x4:0x5:0x5:0x6:0x6:0x7:0x7:pop:peek


Here is how to use tc2exp to directly translate TCINDEX to EXP bits:

mplsadm2 -A -O 0
Key: 0x00000002
mplsadm2 -O 0x2 -o tc2exp:0x7:0x0:0x0:0x1:0x1:0x2:0x2:0x3:0x3:0x4:0x4:0x5:0x5:0x6:0x6:0x7:0x7:push:gen:17:set:eth0:ipv4:192.168.1.1

NOTE: the first number after tc2exp is a mask against TCINDEX.
