Interface Configuration Guide

the interfaces supported by this series of switches include ethernet interfaces, management ethernet ports (hereinafter referred to as management ports), console ports (hereinafter referred to as serial ports), and usb ports for the specific interface types and quantities supported by each model, please refer to the product installation manual this chapter primarily introduces the configuration and commands related to management ethernet ports and ethernet interfaces ethernet interface for management configuration ethernet interface for management configuration introduction introduction the management port, usually with an rj 45 connector, is used to connect to a back end computer for debugging or to connect to a remote device for remote control it is generally named eth0 or mgmt 0 in the switch for asterfusion data center series products, the ip address is automatically obtained via the dhcp management port when asternos is installed, and can be viewed via the linux command /sbin/ifconfig eth0 or " sudo ifconfig eth0 once the system has been installed automatically, you can log in to the switch directly via ssh management port configuration management port

rules for numbering default rules for numbering the ethernet interface numbering format for asterfusion products is x/y x indicates the board number there are no boards in the current series, so x is specified as 0 y indicates the interface number, starting from 0 and increasing it should be noted that the naming intervals vary for different rate interfaces 25ge interfaces are numbered in increments of 1, e g , 0/0, 0/1 , and so on; 100ge and 200ge interfaces are numbered in increments of 4, e g , 0/0, 0/4, 0/8 , and so on; and 400ge interfaces are numbered in increments of are 8, such as 0/0, 0/8, 0/16 , and so on alias mode rules for numbering alias mode rules for numbering in addition to the default mode, the alias attribute (interface alias) is defined, with a one to one

configure interface self negotiation configure interface self negotiation in the network, if the switches at both ends of the link cannot negotiate the appropriate data transmission capacity, the two parties cannot communicate properly the self negotiation function provides a way for interconnected devices to exchange information so that the switches at both ends of the physical link automatically select the same operating parameters through interactive packets in order to achieve the maximum transmission capacity that both parties can support the self negotiation includes the duplex mode and interface speed of the interfaces at both ends once the negotiation is passed, the switches on both ends of the link are locked to the same duplex mode and interface speed in non self negotiating

unhandled content type configure the interface mtu configure the interface mtu the network layer generally needs to limit the maximum length of each packet sent when the network layer receives a copy of an ip packet to be sent, it which interface it should be forwarded to and queries the maximum transmission unit (mtu) of that interface the network layer compares the mtu value with the length of the ip packet to be sent if the length of the ip packet is greater than the mtu value, then the packet is fragmented and the length of the fragmented packet is less than or equal to the mtu the size of the mtu determines the maximum number of bytes that can be sent at one time by the sender a correctly configured mtu value is a prerequisite for proper and efficient communication between devices when the packet size in the network is large but the mtu configuration is too small, it may cause excessive packet fragmentation, which may be discarded by the qos queue and affect normal data transmission; if the mtu configuration is too large, it may exceed the maximum value that the receiving end can handle or exceed the maximum value that a device passing through on the sending path can handle, which may also cause packet fragmentation or even discard, adding to the burden of network transmission and affecting the normal transmission of data by default, the mtu of the interface is
