Ethernet Interface Configuration

introduction introduction ethernet interfaces are commonly used for carrying out business related tasks and data transmission they are often referred to as ports numbering scheme numbering scheme the numbering scheme for ethernet interfaces in this product series is as follows ethernetx here, x represents the interface number, starting from 1 and increasing incrementally it's important to note that the naming conventions for interfaces may vary based on the series for instance, in enterprise level products with 100g interfaces, the naming interval for 100g interfaces is 4 taking the example of cx206p 48s m h, the interface with the number 49 is the first 100g interface, and its name is ethernet49 the second 100g interface is named ethernet53, and so on default configuration of interfaces default configuration of interfaces parameter default value interface management status up interface fec (forward error correction) disabled interface description n/a interface mtu (maximum transmission unit) 9216 bytes interface poe (power over ethernet) supply disabled interface lldp (link layer discovery protocol) function disabled interface mac address same as device mac address basic configuration of interfaces basic configuration of interfaces the product series supports interface speeds of 1g, 10g, 25g, and 100g for example, the cx204y 48gt, cx204y 24gt, and cx206y 48gt series default to interface speeds of 1g and 25g the cx204y 48s series defaults to 10g and 25g speeds the cx206p 48gt series defaults to 10g and 100g speeds operation command description enter the system configuration view configure enter the interface view interface ethernet id set interface description description string set interface speed speed {1000|2500|10000|25000} different types of interfaces support different configuration parameters please execute the speed ? command in the relevant interface view to view specific options modify interface fec mode fec {rs|fc} by default, the fec mode is disabled the fec mode must be consistent at both ends of the link for the interface to come up use the no fec command to disable the fec mode for the interface enable interface poe supply function no shutdown by default, the poe supply function for the interface is disabled use the no poe enable command to disable the poe supply for the interface note in the cx206p 48s series, the 10g interfaces do not support configuration at 25g speed the 10g ports of the cx532p m series products do not support being configured to 1g speed configuring layer 2/3 mode switching for ethernet interfaces configuring layer 2/3 mode switching for ethernet interfaces by default, the switch's interfaces do not belong to any vlan and have no ip address configured when an interface is configured with an ip address, vrf, or other layer 3 attributes, it automatically switches to layer 3 mode if you need to change the layer 2/3 mode of an interface, you should first remove the layer 3 attribute configurations from the interface afterward, execute the no router interface command operation command description enter the system configuration view configure enter the interface view interface ethernet id switch the interface operation mode to layer 2 no router interface configuring interface splitting configuring interface splitting interface splitting refers to dividing a 100g bandwidth physical interface on the device into multiple independent lower bandwidth interfaces to meet the requirements of connecting to lower bandwidth interfaces the device supports splitting a 100g interface into four 1g/10g/25g interfaces after splitting, each interface is assigned an independent identifier for example, when a 100ge interface like ethernet17 is split into four 10ge interfaces, the resulting interfaces are numbered ethernet17 to ethernet20 note when splitting or canceling splitting, you need to check the configurations on the interface clear all configurations before performing the split or cancel split operation after performing the split or cancel split operation, the device needs to be restarted for the changes to take effect the command to cancel splitting must be executed on the first interface generated after splitting the last two 100g interfaces of the cx532p m series products do not support splitting operation command description enter the system configuration view configure enter the interface view interface ethernet id split the interface breakout {4x25g|4x10g|4x1g} unsplit the interface no breakout maintenance interface maintenance interface operation command description view interface description show interface description view interface poe supply information show interface poe \[detail] view interface status show interface status view interface module information show interface transceiver eeprom dom \[ ethernet id ] view interface statistics show counters interface \[ ethernet id ] clear interface statistics clear counters interface
