The default MTU size is also dependent upon the ONT type. The GP1000x ONTs have an MTU size of 2k, while the GPR3000x ONTs have an MTU size of up to 9k. I'm not sure what ONT version you are using, but older releases had an issue with displaying the correct size. The …
RFC 2516 - A Method for Transmitting PPP Over Ethernet (PPPoE) RFC 3817 - Layer 2 Tunneling Protocol (L2TP) Active Discovery Relay for PPP over Ethernet (PPPoE) RFC 4638 - Accommodating a Maximum Transit Unit/Maximum Receive Unit (MTU/MRU) Greater Than 1492 in the Point-to-Point Protocol over Ethernet (PPPoE) ePMP PPPoE Configuration and Troubleshooting In some cases, verifying the configuration of the following parameters may improve the performance of the PPPoE connection: MTU Size (1492 bytes max) – A mismatch of MTU size between PPPoE server and client can result is smaller than optimal packets, causing throughput issues and unnecessary fragmentation of packets. Understanding MTU and MRU Configuration for PPP For PPPoE subscribers, the PPP MRU or PPP MTU size can be greater than 1492 bytes if the PPP-Max-Payload tag is received in the PPPoE Active Discovery Request (PADR) packets. The configuration of … The default MTU sizes for different network topologies Apr 17, 2018
Understanding MTU and MRU Configuration for PPP
MTU or Maximum transmission unit is a topic that pops up every once in a while in different discussions. = Ethernet v2 MTU (1500) – PPPoE Header (8) PPPoE over (1501 – 9198) – PPPoE Header (8) What happens if a packet size is bigger than path MTU? If one host is sending packets that are having a bigger length than the path MTU and Solved: MTU is it really 1492 | Tech Support Guy Feb 24, 2008 Solved: Manually Set MTU for Network Connect/Pulse - Pulse
IP fragmentation, MTU issues using PPPoE Vodafone sure
MTU Size Maximum Transmission Unit; the size in bytes of the largest data unit that the device is configured to process inside the PPPoE tunnel. Users may enter a MTU value up to 1492 bytes. However, if the MTU determined during link negotiations with the PPPoE server is less than this user-specified value, the PPPoE client uses the smaller
