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\ \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\ \table 1 management port configuration\ purpose commands description

are virtual interfaces that are capable of data exchange functions but do not physically exist and need to be created through configuration this section focuses on the several types of logical interfaces supported by the switch, as shown in the following table \table 5 types of logical interface\ type of logical interface description vlanif interface vlanif interfaces are vlan based logical interfaces with layer 3 characteristics, each vlan corresponds to a vlanif interface lagif interface lagif interface is a bundle of multiple ethernet interfaces into a logical interface with layer 2 characteristics or layer 3 characteristics each ethernet interface that is bundled together is called a member interface ethernet layer 3 sub interface ethernet layer 3 sub interfaces are logical interfaces with layer 3 characteristics configured on a physical interface, and multiple sub interfaces can be configured on a physical interface loopback interface loopback interface is logical interface, and any data packets sent to it are considered to be sent to the switch itself once it has been created, its physical and link protocol state is always up until it is deleted loopback interfaces are configured with an ip address and can then be published to the public \logical interface default configuration\ the default setting of the logical interfaces is shown in the table below \table 6 logical interface default configuration\ parameters default value vlanif interface none lagif interface none ethernet layer 3 sub interface none loopback interface default ip address is 10 1

as service interfaces to undertake service transmissions and are sometimes referred to as ports \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\ in addition to the default mode, the alias attribute (interface alias) is defined, with a one to one relationship with the physical port, related to the interface speed with the naming convention as table 10 shown, where the numbering starts at 1 \table 10 alias schema of interface id naming convention\ interface speed alias 1g g 10g x 25g y 40g q 100g c 200g d 400g qc 800g e note x1 indicates the first 10g interface of the box switch c1 y1 indicates the first 25g interface of the first 100g interface after breakout \interface default setting\ the default setting of the ethernet interface is shown in the table below \table

interface disable interface startup delay 150s \interface base configuration\ this section describes the basic configuration of ethernet interfaces \configure the administrative state of the interface\ the state of the ethernet interface is divided into admin and oper, of which there are two physical states, up and down the communication state may only be up when the administrative state of the interface is up; when the administrative state of the interface is down, the communication state will also be down this command is used to switch the administrative state of an interface by default, the administrative status of the interface is up and the user can turn the interface on or off according to needs \table 12 configure the administrative status of interface\ purpose commands description enter global configuration view configure terminal enter ethernet interface view interface ethernet interface name startup the interface no shutdown shutdown the interface shutdown note once a loopback interface has been created, it will remain up and cannot be shut down or started using the command \configure the interface speed\ the series supports the following interface speeds 10g, 25g, 40g, 100g, 200g, 400g and 800g users can configure the interface speed using the commands in the table below \table 13 configure the interface rate\ purpose commands description enter global

delay time, range \[1, 65535], in seconds \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 mode, the above parameters need to be configured manually \table 16 configure interface self negotiation\ purpose commands description enter global configuration view configure terminal enter ethernet interface view interface ethernet interface name enable interface self negotiation autoneg advertise self negotiation speed advertised speeds { speed | all } speed specify negotiation speedall advertise all supported speed \configure the interface fec mode\ fec (forward error correction) is an error correction method that improves signal quality by attaching error correction information to the data packet at the transmitter side and using the error correction information at the receiver side to correct errors generated during transmission, but also causes some delay to the signal the user can choose to turn this function off or on depending on the actual situation the fec methods supported by the switch are rs, fc and none note the fec method must be the same at both ends of the link, otherwise the interface will not be up \table 17 configure the interface fec mode\ purpose commands description enter global configuration view configure terminal enter ethernet interface view interface ethernet interface name configure the interface fec mode fec { rs | fc } \configure interface layer 2 and 3 mode switch\ when using this command to switch between layer 2 and layer 3 modes of interface, only attribute configuration information (e g shutdown, description configuration) or configuration information that is supported by both layer 2 and layer 3 interfaces can be present under the interface for the mode switch function to take effect there must not be any configuration that is not supported by the switched interface mode if there are unsupported configurations on the interface, please clear all these configurations before executing the switchport or no switchport command for example, when an ip address is configured on interface 0/1, the ip needs to be removed before the switchport command can be executed \table 18 configure layer 2 and 3 mode switch for interfaces\ purpose commands description enter global configuration view configure

interface, also known as a rif (router interface) the layer 3 port works at the network layer and can be configured with ipv4/ipv6 addresses, handle layer 3 protocols and provide route functions \configure the interface ip address\ \table 23 configure the interface ip address\ purpose commands description enter global configuration view configure terminal enter ethernet interface view

addresses with the host portion all zeros are not allowed, but all ones are allowed \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 9216 bytes \table 24 configure the interface mtu\ purpose commands description enter global configuration view configure terminal enter ethernet interface view interface ethernet interface name configure the interface mtu mtu mtu mtu range 1312 to 9216 \configure the mac address of the interface\ by default, the mac address of the interface is dynamically
