Some Interfaces configured under interface-range are not working with applied configuration

Some of the interfaces works in the interface-range configuration for a while and stops working on the same configuration.
 

• Interfaces do not assign the vlan when connected with the end host.
• Interfaces does not come up even after reseat of end host on same port, and other ports which are under same interface-range configuration.
• We would some ports working with same vlan under same interface-range configuration.
• The port does not come up but the vlan will be mapped to port correctly.

We can perform the following to overcome the challenges on these interfaces:

• We need to see any configuration changes on the interfaces. Check the configuration on the interfaces and vlan mapped with specific to interface-range as below:

root@user> show configuration interface ge-0/0/X | display inheritance
root@user> show configuration interface ge-0/0/X | display inheritance | display set 
root@user > show ethernet-switching interface ge-0/0/X
root@user >show vlans

• Test the same host device with any other working vlan and see if the port comes UP and learning MAC.
• Check the interfaces status to validate if the respective vlan is mapped as above-mentioned commands.
• Reconfigure the interface-range configuration with non-working vlan to fix the issue.
• The ports will work as expected after reconfiguring and vlans will be mapped appropriately on the respective interfaces.
