Symptoms

A Line card failed to boot when inserted in an MDS Director slot which was previously populated.

When the new line card is the same model as the original line card, then the following syslog message is seen:

%PORT-5-MODULE_BRINGUP_NOT_ALLOWED: Not allowing module 8 to come up for reason: Speed group configuration is not supported. (0x4029018c)

If the new line card is a different model than the original line card, then the following syslog message is seen:

%PORT-5-MODULE_BRINGUP_NOT_ALLOWED: Not allowing module 10 to come up for reason: Speed change not allowed (0x4029007f)

In both scenarios, the following sequences of syslogs are recorded:

%VMM-2-VMM_SERVICE_ERR: VDC1: Service SAP Port manager (high) for slot 8 returned error 0x402901ac (Module insertion failed) in if_bind sequence

%MODULE-2-LCM_MODULE_INSERT_FAILURE_NEG_RSP: Slot-8 has failed to boot up because of service "Im SAP" due to module insertion failure

The module finally goes into a failure state as shown in show module command:
