Parameters 
group-id: Specifies a PEX group ID. The value is fixed at 1. 
Usage guidelines 
To allow user-side ports of different PEXs to join the same aggregation group, you must assign the 
cascade ports to which the PEXs are attached to the same PEX group. 
If you delete a PEX group, all PEXs in that group will go offline with all settings issued from the parent 
device removed. 
Examples 
# Create PEX group 1 and enter PEX group view. 
<Sysname> system-view 
[Sysname] pex group 1 
[Sysname-pex-group-1]
