Failed to http firewall (pdm) page

Dear sir,

We have an existing 5 ip address 192.168.81.15-18 that able to http into the pdm page. We try to add in 4 new ip address 192.168.81.11-14 for http into the pdm page as well. Hereby we applies below steps 1 & 2 to achieve the objective.We try to use 1-4 pc that used the new ip address 192.168.81.11 , 192.168.81.12, 192.168.81.13 & 192.168.81.14 to http into the pdm but we not able to login as shown in attachment "can't login.jpg" and prompt up error message as shown below --Java Error--.

Please advise any idea to solve this issue. Thank you very much and appreciation.

Step 1

To identify the IP addresses from which the FWSM accepts HTTPS connections, enter the following command for each address or subnet:

hostname(config)# http source_IP_address mask source_interface

Step 2

To enable the HTTPS server, enter the following command:

hostname(config)# http server enable

For example, to enable the HTTPS server and let a host on the inside interface with an address of 192.168.1.2 access ASDM, enter the following commands:

hostname(config)# http server enable

hostname(config)# http 192.168.1.2 255.255.255.255 inside

To allow all users on the 192.168.3.0 network to access ASDM on the inside interface, enter the following command:

hostname(config)# http 192.168.3.0 255.255.255.0 inside

Re: Failed to http firewall (pdm) page

PIX Device Manager (PDM) versions 3.0(1) , 3.0(2), 4.0(1), and 4.1(1), and IDS Device Manager (IDM) version 5.0(1), are incompatible with Java Plug-in versions 1.4.2_08 and 1.5.0_02 or later. If these Java Plug-ins are used in conjunction with the impacted PDM or IDM releases, the application will not load.

The latest maintenance releases PDM 3.0(3) and later, PDM 4.1(2) and later, and IDM 5.0(2) and later resolve this issue.

Re: Failed to http firewall (pdm) page

Hi fungchai2020,

please check if your problem still occures if you downgrade to some Java Version 1.6_6. I've often noticed that Cisco has some problems with Java versions later in ASDM/ PDM etc.

cheers

michael
