An engineer is configuring ACI VMM domain integration with Cisco UCS-B Series. Which type of port channel policy must be configured in the vSwitch policy?
UCS-B = Mac-Pinning
" [..] the only supported load balancing mechanism when UCS B series is used is Route Based on Originating Virtual Port. If you configure a mac-pinning policy, it programs the port groups to use this mechanism. This is very important in order to prevent packet loss."
By default on the DVS, the Discovery Protocol used is LLDP. This is fine for any servers that support LLDP, but the UCS B series blades only support LLDP on UCSM version 2.2(4b) and later. Because of this, ESXi cannot report LLDP information to the APIC, unless you are on the correct code.
As an alternative to LLDP, use CDP in order to discover the hosts. In order to get the DVS to use CDP, configure a vSwitch policy on the VMM Domain that has CDP enabled and LLDP disabled.
Along with this, the only supported load balancing mechanism when UCS B series is used is Route Based on Originating Virtual Port. If you configure a mac-pinning policy, it programs the port groups to use this mechanism. This is very important in order to prevent packet loss.
