Issue the command show ip interface brief to view whether the switch has Gigabit port and then Issue the command show interface gigabit ethernet < port number>.

This command gives all information like MTU, MAC address and speed.

You are not answering me.

These commands don't permit me how long gigabyte port has been up.

Issued the command like #sh int g/2/35 instead of 2/35 you enter which port you want see.

I'm afraid the only way I know to do it is to have it syslog link-event traps. At least that way you get a written record as well.

Yes but I haven't a syslog infraestructure.

Tha most seemed that I discovered that I will need is with sh log command that It shows that time when interface changed state to down and goes up again.
