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

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

Your picture show right direction, ODD on Top, EVEN number down.

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

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.
