Issue/Introduction

How can I check and confirm with the help of CA Spectrum if an interface is really down?

Environment

Any

Resolution

To determine if an interface is down you need to determine in which state is the interface is.

1. Check on your CA Spectrum and Select the device model in question.

2. Click on the Interface tab.

3. Check on the Admin status and Oper Status ( if is not present you can right click and add column)

4. if you still have doubts that the interface is down, then you need to check on the OID coming from the Device:

1.3.6.1.2.1.2.2.1.7 - ifAdminStatus

1.3.6.1.2.1.2.2.1.8 - ifOperStatus

5. This can be done either calling for that specific OID along with the index of the interface:

* Click on the Component details of the Interface and select attributes column.

* Type ifindex and copy the number in this case 32 is the index.

6. Then you can use the MibTools utility from Ca Spectrum to call the OID

ifOperStatus 1.3.6.1.2.1.2.2.1.7.32
ifAdminStatus 1.3.6.1.2.1.2.2.1.8.32

This will provide you the state of the interface straight from the device as CA Spectrum sees the device.
