**Table 1** MTU management
Object	Description	Value	Remarks
/ietf-interfaces:interfaces/interface/ietf-ip:ipv4/mtu	Indicates the MTU for IPv4 traffic on an interface.	Physical interface, VLANIF interface, Eth-Trunk interface, physical sub-interface, and Eth-Trunk sub-interface: The value is an integer that ranges from 128 to 9216, in bytes. VE sub-interface: The value is an integer that ranges from 46 to 1500, in bytes. VBDIF interface: The value is an integer that ranges from 46 to 1560, in bytes. Tunnel interface: The value is an integer that ranges from 128 to 1530, in bytes. For the S5720-EI, S5720-HI, S5730-HI, S6720-EI, S6720-HI, and S6720S-EI, the value ranges from 128 to 9216. For other device models, the value ranges from 128 to 1530. The default value is 1500 bytes.	-
/ietf-interfaces:interfaces/interface/ietf-ip:ipv6/mtu	Indicates the MTU for IPv6 traffic on an interface.	GE interface, GE sub-interface, XGE interface, XGE sub-interface, 25GE interface, 25GE sub-interface, MultiGE interface, MultiGE sub-interface, tunnel interface, and VLANIF interface: The value is an integer that ranges from 1280 to 9600, in bytes. Other interfaces: The value is an integer that ranges from 1280 to 1500, in bytes. The default value is 1500 bytes.	-
