Hello,
let's take this port-profile (port-Channel) as exemple:
!
port-profile type ethernet Channel-VLAN1601
description Channel Uplink Access to VLAN1601
vmware port-group
switchport mode access
switchport access vlan 1601
channel-group auto mode on mac-pinning
no shutdown
state enabled
!
When this port profile is associated to a vmnic the port-channel in created automatically with an auto number.
Is it possible to force the po number to vmnics ? Let's assume that I'd like to have all PO from VEM4 starting with PO4x ?

Currently the Port Channel #'s are sequentially assigned during creation. They do not inherit the vmnic # (unlike the Sub group IDs when using MAC pinning).
If you want administrative control over the assignment of PC numbering you can manually create them instead. This of course adds a great deal of manual overhead & greater chance for error. Best practice is to let the system assign the PC#.
Regards,
Robert

Thank's for reply ...
I must use MAC-pinning because I'm connecting vmnic1 and vmnic 2 to different switch (Cat2660) therefore the only possibibility is MAC-pinning that require auto mode isn't ?

You could use the auto "sub-group cdp" option, but MAC Pinning is doing the same thing, and is a better option (doesn't rely on CDP timers which could delay link up) and doesn't require CDP for that matter on the upstream switches (in case of non-Cisco switches or those with CDP disabled).
