interpret show interface status and capability command

[n2sj]

Hi,

I am new to Alcatel Omniswitch and currently working on perfomance problem of particular port.

I have checked with status with "show interface status" command, for some port it shows duplicate line (1/1) as below.
Slot/ AutoNego Speed Duplex Hybrid Speed Duplex Hybrid Trap
Port (Mbps) Type (Mbps) Mode LinkUpDown
-----+--------+------+------+------+--------+------+------+------
1/1 Enable - - - 1000 Full PF -
1/1 Enable 1000 Full C Auto Auto PF -

Other port just one line.
2/25 Enable - - - Auto Auto NA -

From the document, duplicate line appear if it is combo port. But what is difference between first and second line?


Another question is capability, if I look at combo port of capability it show like below.
Slot/Port AutoNeg Flow Crossover Speed Duplex
-----------+---------+--------+-----------+----------+----------
1/1 CAP EN/DIS EN/DIS - 1G Full
1/1 DEF EN DIS MDI 1G Full

Document said "CAP this field displays the valid line speed configurations for the port. DEF this field displays the default line speed settings for the port. The possible values are 10/100, 100,1G, 10/100/1G, or Auto"

Does this mean, first line (CAP) is possible configuration of 1/1 and second line is actual configuration?

Thanks for your help in advance,

Thanks,
