ucs fabric interconnect learns dynamic MAC address

Use policies such as Boot policies for service profiles.Name Service Profiles to match a particular use case.Leverage a deterministic logical addressing scheme for UUID, WWNN/WWPN, and MAC addresses to represent a given compute resource.Map Service Profiles to blades with a deterministic approach By distributing compute resources across I/O modules and chassis uplinks, fault domains are limited and better utilization can be achieved.Use Service Profiles to manage compute resources logically.Pre-provision SAN resources where applicable to reduce deployment time and enhance stateless infrastructure.Use host-based multipathing for redundancy and load-balancing.Use VSAN names and IDs that correlate to upstream fabrics (where applicable).Leverage Boot Policies to distribute initial boot traffic across backend storage array ports.Utilize default pinning (round robin) for server vHBA to uplinks.Leverage Boot from SAN to enable a stateless infrastructure.Utilize System QoS to prioritize traffic between environments at the vnic level Guarantees minimums but does not rate-limit those interfaces.Reserve several VLANs for use internally for FCoE traffic.

Use meaningful names for VLANs within UCS.

Enable STP Port Fast and type “edge trunk” on upstream switch interfaces.

Prune unnecessary VLANs from upstream interfaces.

Match native VLAN tags between the Fabric Interconnect and northbound switch ports it is not necessary that this tag match the vnic trunk parameters.

Use Port Channels for connectivity to upstream resources pinned server interfaces will take advantage of the Port Channel hashing algorithm.Leverage host-based methods to enable traffic that is east-west in nature to be switched locally on an FI.Utilize default pinning (round robin) for servers to uplinks.Use End Host Mode (EHM) where possible to allow for simple deployment methodologies.This list is not exhaustive but is useful for any UCS deployment. This document explains some best practices and common mistakes observed in UCS setups and provides recommendations.
