Ethernet Interface Configuration
Ethernet interfaces are commonly used for carrying out business-related tasks and data transmission. They are often referred to as ports.
Numbering Scheme
Section titled “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
Section titled “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
Section titled “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 |
hint{type=“warning”} 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 |
