In computer networking, the maximum transmission unit (MTU) is the size of the largest protocol data unit (PDU) that can be communicated in a single network layer transaction. The MTU relates to, but is not identical to the maximum frame size that can be transported on the data link layer, e.g. Ethernet frame.. Larger MTU is associated with reduced overhead.

mtu size limited to 1492 on PPPoE on EA9500 - Linksys Bell uses PPPoE+VLAN ID to established the connection. I understant that the usual maxium mtu on a PPPoE connection is 1492 (1500 minus the 8 bits that PPPoE is adding). but that said, Bell allows us to use 1500 (1500+8).

Packet size, often referred to as MTU (Maximum Transmission Unit) is the greatest amount of data that can be transferred in one physical frame on the network. For Ethernet, the MTU is 1500 bytes, for PPPoE 1492, dial-up connections often use 576. Each transmission unit consists of header and actual data.

Mar 29, 2017 Changing the MTU The Maximum Transmission Unit (MTU) is the maximum length of IP packet that a Layer 2 packet can contain. IP packets that are longer than the MTU are fragmented and sent in multiple Layer 2 packets. You can change the MTU globally or on individual ports. The default MTU is 1500 bytes for Ethernet II packets and 1492 for Ethernet SNAP packets. Maximum MTU for PPPOE - Plusnet Community
