problem about WS-X6724-SFP GLC-T

Answered Question

my environment:

WS7609-S <-----> 7204

SUP-720-3B with c7600s72033-adventerprisek9-mz.122-33.SRE1.bin

modules: WS-X6724-SFP , and several GLC-T

now i met these trouble/questions below:

1st: I try to use a twist UTP(straight) connect between 7609's GLC-T 1000M interface and 7200's FastEthernet interface.

But they couldn't go up both line and protocol.

2nd: Now I've to using the GigaEthernet of SUP720 instead of the GLC-T.

That would work well.

Q1: GLC-T can only work in 1000M mode ?

I can't input "speed 100" command in config-if

It is not the GLC-T, where it supports 10/100/1000

It is the 6724 line card. Since it is a mix media (SFP) line card, it only supports 1G.
