Nexus 5500 FCoE and Jumbo MTU I happened across an interesting scenario this morning while I was doing configuring jumbo MTU of 9216 on the Nexus 5500 switches in our lab. Storage and virtual Ethernet can take advantage of a maximum transmission unit (MTU) up to a 9000 byte ‘jumbo' frame if the iSCSI network supports the larger MTU. If you’ve forgotten to enable jumbo frames/9k MTU on your client device you’re sending the ping from. In all other situations, the effort of configuring jumbo frames everywhere on your network is not worth the marginal improvement, and has the potential of slowing down or breaking non-jumbo frame clients. MTU settings are changed switch-wide on 3750 switches, and not for individual interfaces. Does anyone know the default command system jumbo mtu 9216 is enough to allow jumbo mtu frames on fabricpath interfaces ? or Dow we need to configure mtu 9216 on Layer two interfaces as well ?. The default network proposal uses a MTU value of 1500. This is a know bug of Nexus 5000. I feel this good and high quality product. 0 this can be accessed by enabling unsupported tech support mode and on 4. User cannot change the MTU on an individual interface. Nimble recommends Jumbo frames. jumbo-frames size <1519-9216> default jumbo-frames enable. Some would even be shocked to learn jumbo frames are not a panacea. 1 Cisco Nexus 9000 Jumbo Frame Configurations Cisco Nexus 9000 switches support jumbo frame; however it is not enabled by default. PLEASE read these two articles first, as they do a lot better job at explaining the structure that we're going to be putting together in the video. A jumbo frame is a frame where the MTU has been adjusted to larger than the standard size. If Rx-No-Pkt-Buff increments and TxPauseFrames also increments, it means that the remote end disregards the pause frames (does not support flow control) and continues to send traffic. Configure a Virtual System to enable Jumbo Frames on these interfaces types: Physical interface; Bond interface ; VLAN interface. This document will also work for just about any UCS-based environment, however you will have to check on how to enable Jumbo Frames for their storage array.
