Port Numbering

Port numbers

In the AlliedWare Plus OS, switch ports are named portx.y.z (e.g. port1.0.1), where:
the first number (x) is the stack ID number
the second number (y) is the module number.
For ports on the base unit, the module number is 0.
For XEMs, the module numbering starts at 1 on the left-hand side of the switch when you
view the switch from the front, as the following figure shows for an x900 series switch:
For switches with multiple rows of XEMs, the numbering starts at the top left-hand corner,
as the following figure shows for a SwitchBlade x908:
The XEM bay number is printed on the top left-hand corner of each XEM bay.
the third number (z) is the port number.
