Port numbering/placment

Andrey.A

Hello,

As I'm not that familiar with Cisco equipment, I need some clarification about ports placement on card C9400-LC-48U, are ports placed like in picture I attached

ports.jpg

Or they are scheduled in upper row: 1-6; 13-18; 25-30; 37-42 / bottom row 7-12; 19-24; 31-36; 43-48

Maybe it seems like a silly question to you, but I really need to sort this out.

Thank you all,

Andrey

Hi,

The port numbering starts from the first port on the far left, top. So, the first port is 1/1 and the port below it will be 1/2, the next port on the top will be 1/3 and the one below is 1/4 and so on..... This is if the blade is inserted in slot 1 but if the blade is inserted in slot 2 than the first number starts with 2 e.g 2/1, 2/2, 2/3, 2/4 and so on...

Hi @Andrey.A 

 

Many switch models have the order of the ports indicated, as you can see in this image.

This order is the same on the other switches.

Hi Mr

How can I understand the interface if its for example 3/0/1 ... how do I figure out what port it is .

Thanks 

Hi

Three numbers are used with equipment that can use expansion cards.

G1/0/1 is switch 1, built-in device card (0) and port 1.

G5/0/28 is switch 5, built-in device card (0) and port 28.

If the switch is using expansion cards, the expansion card ports will be middle number.

Ten3/1/4 is a ten-gigabit port on switch 3, expansion card 1, port 4.
