Customer founds that all the MX-SPC3 cards failed to bring either the VMS unit interfaces, or mams unit intefaces to be up in the MX Virtual-Chassis box.

Further investigation found there has traceoptions enabled under the [security] stanza. Once the traceoptions is disabled, the problem is cleared.

This issue is under investigation by Juniper engineering team. As a workaround, customer can disable the traceoptions under the [security] stanza to make the MX-SPC3 work.
