The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This document describes how to determine the serial numbers of various replaceable components on Cisco Catalyst switches.
There are no specific requirements for this document.
The information in this document is based on these software and hardware versions:
Various Catalyst switches
Various software versions
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.
Refer to Cisco Technical Tips Conventions for more information on document conventions.
The serial numbers are necessary to create a database of the parts in the network. When you create a service request with Cisco Technical Support , you must have the serial number of the affected devices at hand. This requirement is especially the case when you need a replacement part, or return materials authorization (RMA).
The serial number of Cisco Catalyst switches cannot be modified. For management purposes, you can configure the Cisco Catalyst switches that run Cisco IOSĀ® software to return a custom string. In order to create a custom string, issue the snmp-server chassis-id command in global configuration mode.
Note: For specific information about show commands, see Show Commands.
To determine the serial number for the chassis and other components, issue the show idprom
command:
6506#show idprom ? all selects all FRU-types backplane specify backplane clock specify clock <number> earl specify earl <slot> fan-tray specify fan-tray <number> interface interface name module specify module <slot> power-supply specify power-supply <number> rp specify RP (MSFC) <slot> supervisor specify supervisor <slot> vtt specify VTT <number>
To obtain the chassis serial number, issue the show idprom backplane command:
6506#show idprom backplane IDPROM for backplane #0 (FRU is 'Catalyst 6500 6-slot backplane') OEM String = 'Cisco Systems' Product Number = 'WS-C6506' Serial Number = 'TBA03270652' Manufacturing Assembly Number = '73-3436-01' Manufacturing Assembly Revision = 'A0' Hardware Revision = 1.0 Current supplied (+) or consumed (-) = -A
To obtain the module serial number, issue the show idprom module slot <slot number> command. Alternatively, you can issue the show module command:
6506#show module Mod Ports Card Type Model Serial No. --- ----- -------------------------------------- ------------------ ----------- 1 2 Catalyst 6000 supervisor 2 (Active) WS-X6K-S2U-MSFC2 SAD055006NE 3 0 2 port adapter FlexWAN WS-X6182-2PA SAD04350EEU 4 48 SFM-capable 48-port 10/100 Mbps RJ45 WS-X6548-RJ-45 SAD055108C2 Mod MAC addresses Hw Fw Sw Status --- ---------------------------------- ------ ------------ ------------ ------- 1 0001.6415.a602 to 0001.6415.a603 3.2 6.1(3) 7.5(0.6)HUB6 Ok 3 0001.6413.c86b to 0001.6413.c8aa 1.5 12.1(13)E1 12.1(13)E1 Ok 4 0001.63d3.e77a to 0001.63d3.e7a9 4.0 6.3(1) 7.5(0.6)HUB6 Ok Mod Sub-Module Model Serial Hw Status --- --------------------------- --------------- --------------- ------- ------- 1 Policy Feature Card 2 WS-F6K-PFC2 SAD055004VA 3.0 Ok 1 Cat6k MSFC 2 daughterboard WS-F6K-MSFC2 SAD055006VF 2.0 Ok Mod Online Diag Status --- ------------------- 1 Pass 3 Not Supported 4 Pass
Note: Use the show diagbus
command to determine the serial number of port adapters on the Flex WAN module.
To determine the serial number of the chassis and other components use the show idprom command:
Switch#show idprom ? all show all non-interface IDPROMs chassis show IDPROM for chassis fan-tray show IDPROM for system fan tray interface show contents of gbic connected to this interface module show IDPROM for module power-supply show IDPROM for power supply supervisor show IDPROM for supervisor
To obtain the chassis serial number use the show idprom chassis
command:
Switch#show idprom chassis Chassis Idprom : Common Block Signature = 0xABAB Common Block Version = 1 Common Block Length = 144 Common Block Checksum = 4081 Idprom Size = 256 Block Count = 2 FRU Major Type = 0x4001 FRU Minor Type = 37 OEM String = Cisco Systems, Inc. Product Number = WS-C4506 Serial Number = FOX0627A001 Part Number = 73-8107-04 Part Revision = 01 Manufacturing Deviation String = 0 Hardware Revision = 0.4 Manufacturing Bits = 0x0000 Engineering Bits = 0x0000 Snmp OID = 0.0.0.0.0.0.0.0 Power Consumption = 0 RMA Failure Code = 0 0 0 0 Chassis Block Signature = 0x4001 Chassis Block Version = 1 Chassis Block Length = 22 Chassis Block Checksum = 628 Feature Bits = 0x0000000000000000 MAC Base = 000a.4172.df40 MAC Count = 64
To obtain the power supply serial number use the show idprom power-supply {1 | 2} command:
Switch#show idprom power-supply 1 Power Supply 1 Idprom : Common Block Signature = 0xABAB Common Block Version = 1 Common Block Length = 144 Common Block Checksum = 5857 Idprom Size = 256 Block Count = 2 FRU Major Type = 0x4501 FRU Minor Type = 1 OEM String = Cisco Systems, Inc.

To obtain the module serial number use the show idprom module slot <slot number> command. Alternatively, you can use the show module command:
Switch#show module Mod Ports Card Type Model Serial No. ----+-----+--------------------------------------+-----------------+----------- 1 2 1000BaseX (GBIC) Supervisor(active) WS-X4014 JAB054109H1 3 48 10/100BaseTX (RJ45) WS-X4148 JAB025202M6 4 6 1000BaseX (GBIC) WS-X4306 JAB023403BG M MAC addresses Hw Fw Sw Status --+--------------------------------+---+------------+----------------+--------- 1 000a.4172.df40 to 000a.4172.df41 0.5 12.1(12r)EW 12.1(13)EW(0.34) Ok 3 0050.730b.2340 to 0050.730b.236f 1.0 Ok 4 0010.7bfa.7ca4 to 0010.7bfa.7ca9 2.0 Ok
Use the show version command to determine the chassis serial number and switch model type, as the example here shows. You find all switch stack members, chassis, and serial number information in the output:
