NCS 540 N540-24Z8Q2C-M How to convert 25G port to 10G port?

[jm-barreto]

Greetings

I am recently been working with the NCS 540 router, specifically with the N540-24Z8Q2C-M model. In the specs, the 25GB ports can be used as 10GB. But the link does not go up when placing a 10G SFP. From the information I could find in this link http://networkingbodges.blogspot.com/2019/03/how-to-use-25g-ports-in-110g-mode-on.html, you have to change the ports from 25 to 10 in hw-module. But when I try to change them, it won't let me make the change.

hw-module quad 0 location 0/rP0/CPU0 mode 10g

hw-module quad 0 location 0/RP0/CPU0
mode 10g
!!% 'CfgMgr' detected the 'fatal' condition 'This configuration has not been verified and can not be accepted by the system.'
!

I may be using the wrong location. Can the ports be changed from 25 to 10?

I appreciate any help you can provide.

Ok So i was able to change the 25GB port to 10GB port. As i mentioned before i was using the wrong location

The command is

hw-module quad 0 location 0/0/CPU0 mode 10g 

on config mode. The # after quad represent the group of 4 25GB port. Quad 0 is the first 4 port and quad 1 the last 4 port, in my case i have 8 25GB port.

I get a little nervous bcause after I hit commit the CLI get stuck for a moment but was working again, and when i check the 25GB interface are now 10GB interface.

Before

interface TwentyFiveGigE0/0/0/30

Operational values:
Speed: 25Gbps
Duplex: Full Duplex

After

TenGigE0/0/0/30

Operational values:
Speed: 10Gbps
Duplex: Full Duplex
