To meet the requirements of configuring a QoS policy on Cisco UCS that includes a no-drop class and enables jumbo frames without fragmentation, a QoS system class must be created with an MTU value of 9216 bytes. This MTU size is large enough to support jumbo frames, which can carry more data than standard frames, reducing the number of frames sent and improving network efficiency. The no-drop class ensures that frames are not dropped, which is crucial for certain types of traffic that require reliable delivery, such as storage traffic.
References: The configuration approach is based on best practices for enabling jumbo frames on Cisco UCS blades, as described in the Cisco documentation1. The MTU size of 9216 bytes is commonly used in data center environments to enable jumbo frames
