The "NIC MTU Ping Check" check tests CVM eth0 MTU settings by way of running ICMP echo (ping) with the DF bit (do not fragment) set from each CVM eth0 to all other CVM eth0, and hypervisor host external management IP, and reports back with a FAIL if the packets cannot pass unfragmented. A FAIL would indicate that the upstream network, including

The maximum transmission unit (MTU) is the largest size frame (packet), specified in bytes, that can be sent over a network interface. The MTU is a configurable setting. The default MTU used on Azure VMs, and the default setting on most network devices globally, is 1,500 bytes. The PING utility available in Windows and Linux provides the Understanding the difference between MTU and IP MTU Again to clear any confusion, the reason that MTU and IP MTU can have the same size configured is due to the fact that Cisco’s IOS doesn’t calculate the 14 bytes of Layer 2 headers in the MTU command, so even if I pinged with the maximum MTU which is 1600, the … Determining the optimal MTU size for your Switch to get

Increased MTU in LTE network allows for more efficient exchange between eNodeB and EPC, e.g. MTU value of 1600 in S1-U is sufficient for transmitting 1500 bytes of user data, and mobile network overhead (GTP + UDP + new IP header) without fragmentation. Increased MTU in 2g/3g network brings none or almost none profit.

ping R2 size 1600 is ok. ping R3 size up to 1530 only. ping R4 size up to 1530 only. fromR2: ping R1 size 1600 is ok. ping R2 size 1600 is ok. ping R4 size up to 1530 only. With this, does it mean p2p mpls router does not use the mtu. For the whole network, only 16 bytes is …
