ASA Hidden Interface

[robert.horrigan]

Hi,

My NMS is reporting that the below interface is Up/Down.  I cannot find any reference to this interface in the CLI.  It is not the mgmt or other gig interfaces.  Does anyone have any idea what this hidden interface is?  Appreciate any feed back.

DisplayName	AdminStatus	OperStatus	Type	Name	Mode
IF-asa5520/1 [Null0]	UP	UP	GENERIC	IF-asa5520/1	NORMAL
IF-asa5520/2 [0]	UP	DOWN	GENERIC	IF-asa5520/2	NORMAL
IF-asa5520/3 [outside]	UP	UP	ETHERNETCSMACD	IF-asa5520/3	NORMAL
IF-asa5520/4 [inside]	UP	UP	ETHERNETCSMACD	IF-asa5520/4	NORMAL

It should be gig0/2

If you perform the output of "show int ip brief" on the ASA, you should be able to get a summary of the interface status.

No this is some hidden interface...

Hi Robert,

We would need more information, like what version of ASA software is running, as well as the output of the SNMP walk of the interfaces combined with the "show interface detail" output.  There are some internal interfaces that may be exposed, but we need more information from you in order to provide a better response.

Sincerely,

David.
