Determine the serial number on GBIC

Question

Im trying to determine the serial number of Gbics already installed and running on a Catalyst 2950 switch. Is there a specific command to do so? There is a command on Catalyst 4506 that gives all info regarding the Gbic ("show idprom interface gi 1/1")
Is there something equivalent for 2950?
Thank you in advance!

You may try to snmp poll the entity mib table.
This will give you the name of the physical components:
1.3.6.1.2.1.47.1.1.1.1.7
This will give you the serial number for the components:
1.3.6.1.2.1.47.1.1.1.1.11
Here is an example that shows the component:
.1.3.6.1.2.1.47.1.1.1.1.7.1235 entityMIB.entityMIBObjects.entityPhysical.entPhysicalTable.entPhysicalEntry.entPhysicalName.1235 OCTET STRING Transceiver Gi1/8 "Transceiver Gi1/8"
Here is a poll that references the index number of 1235 (Transceiver Gi1/8) and therefore the GBIC in port Gi1/8:.1.3.6.1.2.1.47.1.1.1.1.11.1235 entityMIB.entityMIBObjects.entityPhysical.entPhysicalTable.entPhysicalEntry.entPhysicalSerialNum.1235 OCTET STRING FGS16450R4R      "FGS16450R4R     "
