MTU Configuration
- Limitations for MTU
- Interface MTU Setting
- MPLS MTU Setting
- Configure L2VPN MTU Negotiation
- Setting the MTU Value for NAT64 Services
You can change the MTU value so that the packets for NAT64 are not fragmented, improving NAT64 translation efficiency. - Configuring Parameters for the Path MTU Test
A path MTU test can obtain the maximum MTU value that does not require packet fragmentation during the packet transmission on the link. - Configuring the MTU for a POS Interface
The MTU is used to reassemble or fragment packets on a POS interface when packets are received or sent on the interface through the IP network protocol. - Configuring the MTU for a Serial Interface
This section describes how to configure the maximum transmission unit (MTU) for a serial interface. The MTUs for two directly connected serial interfaces must be the same. Otherwise, the link between the two interfaces cannot transmit services. - Configuring an MPLS MTU on an Interface
An MPLS MTU can be configured on an interface to determine the maximum number of bytes in an MPLS packet that an interface can forward without fragmenting the packet. - Configuring Path MTU Auto Discovery
Path MTU auto discovery allows BGP to discover the smallest MTU value on a path so that BGP messages are transmitted based on the path MTU. This function improves transmission efficiency and BGP performance. - Configuring the MTU for an Ethernet Interface
MTU is the largest packet of data that can be transmitted on a network, expressed in bytes. MTU is determined by data link layer protocols, and MTU values vary with networks. A proper MTU is a prerequisite for normal communication between network devices.
