CISCO NCS 540 router SFP28 interface rate configuration
Time: 2025-01-16
Moduletek Limited Laboratory uses CISCO N540-ACC-SYS router, according to the device datasheet, the SFP28 interface supports 10G rate, but the rate configuration is different from the regular CISCO switch; the next step is to take you to learn to understand the CISCO NCS 540 series router SFP28 interface rate configuration.
CISCO N540-ACC-SYS router SFP28 interface default state rate of 25G, if directly access to the 10G optical module, the interface can not adapt to the 10G rate and can not be linked up, you need to configure the interface in order to link up. the next use of the MOTEK 25G, 10G optical module access to the N540-ACC-SYS router SFP28 interface for demonstration. SFP28 interface for demonstration.
Figure 1 N540-ACC-SYS Router
Use Motek SFP-25G-LR-C-J12 module, write MSA code, access N540-ACC-SYS router SFP28 interface, default state 25G rate, the module can be normal LINK at 25G rate, at this time the interface FEC mode is RS-FEC.

Figure 2 Division and configuration of SFP28 interface groups
Execute the command "hw-module quad quad-number location 0/0/CPU0 mode port-speed" to configure the SFP28 interface of the router to 10G rate. Note that the interface naming changes after the rate change, the original twentyFiveGigE 0/0/0/29 changes to tenGigE 0/0/0/29.
Figure 3 Configuring the SFP28 Interface Rate to 10G
Use the Motek SFP-10G-LR-C-D12 module, write the MSA code, and access the SFP28 interface of the N540-ACC-SYS router to configure the 10G rate, and the module can be normally LINKed at the 10G rate, and at this time, the interface FEC mode is off.
