Problem: You are Authorized to Access Only Home and Monitoring Views
If you click the Configuration tab in the ASDM, you might recieve this error message: 'you are authorized to access only Home and Monitoring Views'.
Solution
The error occurs due to the user privilege. Go to the PIX/ASA CLI prompt, and create the new user and password with full privilege 15 as shown here:
The full privilege level allows you to log into the ASDM.
Problem: Your Firewall Image has a Version Number Null which is not Supported by ASDM
When you try to run the ASDM interface, the Your Firewall image has a version number null which is not support by ASDM error may be received.
The same error on the FWSM appears as:
This error is caused by one of these reasons:
No ASDM image in the flash
No aaa related configuration for ASDM access through http
Incompatible Java version
Solution 1
Verify whether or not the compatible ASDM image exists in the flash, and then specify the location of the image:
Solution 2
Enter the aaa command for ASDM access through http:
Solution 3
Verify whether or not the Java version is compatible. Then upgrade/downgrade the Java version accordingly and install the JRE.
Solution 4
If you attempt to access the ASDM over a VPN connection, make sure the management-access <ASDM access Interface name> command is configured on the ASA. For example, if the ASDM is accessed using the inside interface, then use the management-access Inside command.

Solution
Downgrade to Java 6 Update 7.
Problem: Unable to Reset the VPN Tunnel using ASDM
The user is unable to reset the VPN Tunnel using ASDM.
Solution
Select Monitoring > VPN > VPN statistics > VPN session and choose active tunnel and log off in order to reset the tunnel.
Problem: Unable to load the DLL 'C:Program FilesJavajre6binclientjvm.dll'
Not able to start ASDM because of the Java version mismatch.
Solution
In order to avoid this error, perform these steps:
Downgrade the Java version to Version 6, Update 7.
Edit the adsm-launcher config file and modify the Java path to the folder that contained the jvm.dll.
Problem: Unable to view access list hit count entry on ASDM
The Hit Counter of ASDM does not display a value, including zero (0).
Solution
ASDM always sends a request for all ACLs in one HTTP server request string to the FWSM. The FWSM device is unable to handle the super long request to its HTTPS server from the ASDM, runs out of buffer space, and finally drops the request. When you have too many access lists, the request from ASDM to the FWSM becomes too long for the FWSM to process. As a result, it does not get the correct response. This is an expected behavior with the functionality of ASDM and the FWSM. Bugs CSCta01974 (registered customers only) and CSCsz14320 (registered customers only) have been filed to address this behavior with no known workaround. A temporary workaround is to use the CLI to monitor the ACL hits.
There are several other bugs filed to address this issue which are superseded by another bug, CSCsl15055 (registered customers only) . This bug shows that the issue is fixed in 6.1(1.54). For the FWSM, the fixed ASDM version is 6.2.1F. The issue has been fixed by tweaking how the ASDM queries the FWSM for the ACL information. Instead of sending one big, long request string that contains all the access list information, the ASDM now splits them into multiple meaningful requests and sends to the FWSM for processing.
Note: The access list hit count entry on the FWSM is supported from version 4.0 onwards.
Problem: Unable to access ASDM when SSL encryption level is set to AES256-SHA1
User is unable to access ASDM when SSL encryption level is set to AES256-SHA1 on the PC.
Solution
This issue occurs when the command ssl encryption rc4-sha1 aes128-sha1 aes256-sha1 3des-sha1 is used which sets encryption level to AES256-SHA1. The issue can be resolved by either removing this command or by installing the JCE version of Java so that the PC becomes AES 256 compatible.
Problem: ASA network objects get deleted when using ASDM version 6.4.5
Cisco Asdm-idm Launcher Not Working For Macos Windows 10
While editing an existing network object using ASDM version 6.4.5, the object disappears from the list of all objects when you click OK.
Solution
Working For Mac Cosmetics
Downgrade to ASDM version 6.2.4 in order to resolve this issue.
Problem: Error - ASDM cannot be loaded. Unconnected sockets not implemented.
The user receives the ASDM cannot be loaded. Unconnected sockets not implemented. error message when accessing the ASDM.
Solution
This error message is the result of an incompatibility between the ASDM version and Java version, and is logged in Cisco bug ID CSCsv12681 (registered customers only) .
In order to resolve this issue, try one of these methods:
Upgrade the ASDM to version 6.2 or later.
Specify the Java version as Java 6 Update 7.
Problem: Performance issues when ASDM configuration size exceeds 512 kb on Windows
Performance issues seen on ASDM when the configuration exceeds 512 kb on a Windows machine.
Solution
ASDM supports a maximum configuration size of 512 kb. If you exceed this amount, you may experience performance issues. For example, when you load the configuration, the status dialog shows the percentage of the configuration that is complete. However, with large configurations, it stops incrementing and appears to suspend operation, even though ASDM might still be processing the configuration. If this situation occurs, we recommend that you consider increasing the ASDM system heap memory.
In order to increase the ASDM heap memory size, modify the launcher shortcut.
Cisco Asdm-idm Launcher Not Working For Mac Os 2
Complete these steps:
Right-click the shortcut for the ASDM-IDM Launcher, and choose Properties.
Click the Shortcut tab.
In the Target field, change the argument prefixed with -Xmx in order to specify your desired heap size. For example, change it to -Xmx768m for 768 MB or -Xmx1g for 1 GB. For more information about this parameter, refer to the Xmx topic in this Oracle document .
Note: This solution applies only to Windows PCs.
Problem: Error received when accessing the IPS functionality tab in ASDM 6.2
After the upgrade to Java 1.6.0_18, ASDM 6.2 generates this error:
Your current Java memory heap size is less than 512 MB. You must increase the Java memory heap size before accessing IPS functionality
Solution
In order to resolve this issue, you need to increase the memory specification to 512 MB:
Use the ASDM launcher on Windows:
For ASDM versions lesser then/equal to 6.2 - Right-click the ASDM launcher icon on the desktop and change the target string value from -Xmx256m to -Xmx512m.
For ASDM versions greater than 6.2 - Go to file C:Program FilesCisco SystemsASDMasdm-launcher.config and update string -Xmx256m to -Xmx512m.
Use the Run ASDM option on Windows/Linux:
When the Run ASDM option is selected, you will receive an option to download the asdm.jnlp file or bring up the ASDM using Java webstart. After you download the asdm.jnlp file, edit it in order to change the 'max-heap-size' value from 256m to 512m. Then, bring up the asdm.jnlp file with Java webstart in order to bring up ASDM.
