Can PagP and static Etherchannel run simultaneously on the same network?

Our network switches are configured to use PagP trunks between them. 

 

I have recently installed a UCS series server for CUCM with two quad NICs and have configured it for NIC teaming on the VM side and on the Cisco side have configured 'static Ether-Channel' (Per Cisco only 'static Ether-Channel' is allowed).

 

However, since doing so I keep getting flooded with syslog messages that state that the Mac addresses of both the Call Manager and Unity server VMs are flapping between port channels (i.e., the 'static Ether-Channel' and the PAgP Ether-Channels). 

 

Can the PAgP and Static Ether-Channels co-exist simultaneously?  I cannot find any documentation, Cisco or otherwise, that states that they can co-exist simultaneously. 

 

FYI, the load-balancing algorithms for each side is the following:

*VM-side NIC Teaming:  Route Based IP Hash 

*Cisco Switches: src-mac

 

Any assistance would be greatly appreciated.

Having PAGP on the uplink should not effect mode-on on the UCS side. Have you tried LACP on the UCS?

HTH

Per Cisco, only the static Ether-Channel (i.e., "on" mode) can be used with NIC teaming on the UCS server.

LACP is not an option on the UCS c-series stand-alone servers.
