Cisco Cisco ASA 5585-X Adaptive Security Appliance Guía Para Resolver Problemas

that you understand the potential impact of any command.

There are three major failure points on which this troubleshooting document focuses. If you adhere to the
general troubleshooting process in this order, this document should help you to determine the exact problem
with ASDM use/access.

• 

• 

• 

There are three essential configurations that are present on the ASA that are needed in order to successfully
access the ASDM:

ASDM Image in Flash

• 

ASDM Image in Use

• 

HTTP Server Restrictions

• 

Make sure that the required version of the ASDM is uploaded to the flash. It can either be uploaded with the
currently run version of the ASDM or with other conventional methods of file transfer to the ASA, such as
TFTP.

Enter show flash on the ASA CLI in order to help you list the files present on the ASA flash memory. Check
for the presence of the ASDM file:

ciscoasa# show flash −−#−−  −−length−−  −−−−−date/time−−−−−−  path

249  76267       Feb 28 2013 19:58:18  startup−config.cfg

250  4096        May 12 2013 20:26:12  sdesktop 

251  15243264    May 08 2013 21:59:10  asa823−k8.bin 

252  25196544    Mar 11 2013 22:43:40  asa845−k8.bin 

253  17738924    Mar 28 2013 00:12:12  asdm−702.bin    −−−− ASDM Image

In order to further verify if the image present on the flash is valid and not corrupt, you can use the verify
command in order to compare the stored MD5 hash in the software package and the MD5 hash of the actual
file present:

ciscoasa# verify flash:/asdm−702.bin

Verifying file integrity of disk0:/asdm−702.bin

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Done!

Embedded Hash MD5: e441a5723505b8753624243c03a40980

Computed Hash MD5: e441a5723505b8753624243c03a40980

CCO Hash      MD5: c305760ec1b7f19d910c4ea5fa7d1cf1

Signature Verified

Verified disk0:/asdm−702.bin

This step should help you verify if the image is present and its integrity on the ASA.
