Issue/Introduction

What attribute is used to populate the "serial_nbr" field in the Spectrum SRM reporting database?

Environment

Release : 10.4.x

Component : Spectrum Core / SpectroSERVER

Resolution

• For a device model the Serial_Number (0x10030) attribute is used to populate serial_nbr in the SRM devicemodel table.
• For modules the NRM_LineCardData (0x12a6d) attribute is used to populate serial_nbr in the SRM devicemodule table.

Additional Information

• NRM_LineCardData (0x12a6d) is populated from the device Entity MIB\table.
• NRM_LineCardData (0x12a6d) is refreshed based on configInterval attribute (10 Minute default).
• This attribute is on a device's application model but the application model name can vary based on the vendor, for example some Cisco devices use CatStackApp where Extreme Devices use ExtrChas2App.

While reading the NRM_LINE_CARD data SRM will fetch all those physical entities and save them into the devicemodule table.

In SRM while processing the device model it will verify the mtype is derived from parent type ID (0x1004b) and not in the below list then it will be considered as Device type.

UNPLACED_MTYPE : 0x103d8
DIALUPLINK_MTYPE : 0x22f0000
INB_MTYPE : 0xd80023
SFSMARTCELL_MTYPE : 0xd80033
COAXSEGMENT_MTYPE : 0x102e3
FANOUT_MTYPE : 0x100ae
WASEGMENT_MTYPE : 0x10322
GENFDDIMAC_NM_MTYPE : 0xf40009
GENTRSTN_NM_MTYPE : 0xf4000b
PROVIDER_CLOUD_MTYPE : 0x1048f

All the device types may not contain the LINE_CARD data. For whichever devices the Line_Card data is present, it will be processed and saved in DB.

If the entity MIB exists on a given device the attribute is populated but there is no static mapping of which devices types will provide this data.
