If you migrate to 8.3 or later, the ASA creates named network objects to replace inline IP addresses in some features. In addition to named objects, ASDM automatically creates non-named objects for any IP addresses used in the configuration. These auto-created objects are identified by the IP address only, do not have a name, and are not present as named objects in the platform configuration. When the ASA creates named objects as part of the migration, the matching non-named ASDM-only objects are replaced with the named objects. The only exception are non-named objects in a network object group. When the ASA creates named objects for IP addresses that are inside a network object group, ASDM retains the non-named objects as well, creating duplicate objects in ASDM. To merge these objects, choose Tools > Migrate Network Object Group Members. See Cisco ASA 5500 Migration to Version 8.3 and Later for more information. |

Figure 5-4 Firewall Dashboard Tab
|
|
|
|---|---|
Traffic Overview Pane
Enabled by default. If you disable basic threat detection (see the firewall configuration guide), then this area includes an Enable button that lets you enable basic threat detection. The runtime statistics include the following information, which is display-only :
- The number of connections and NAT translations.
- The rate of dropped packets per second caused by access list denials and application inspections.
- The rate of dropped packets per second that are identified as part of a scanning attack, or that are incomplete sessions detected, such as TCP SYN attack detected or no data UDP session attack detected.
Top 10 Access Rules Pane
Enabled by default. If you disable threat detection statistics for access rules (see the firewall configuration guide), then this area includes an Enable button that lets you enable statistics for access rules.
In the Table view, you can select a rule in the list and right-click the rule to display a popup menu item, Show Rule. Choose this item to go to the Access Rules table and select that rule in this table.
Top Usage Status Pane
Disabled by default. This pane contains the following four tabs:
- Top 10 Services—Threat Detection feature
- Top 10 Sources—Threat Detection feature
- Top 10 Destinations—Threat Detection feature
- Top 10 Users—Identity Firewall feature
The first three tabs—Top 10 Services, Top 10 Sources, and Top 10 Destinations—provide statistics for threat detection features. Each tab includes an Enable button that let you enable each threat detection feature. You can enable them according to the firewall configuration guide.
The Top 10 Services Enable button enables statistics for both ports and protocols (both must be enabled for the display). The Top 10 Sources and Top 10 Destinations Enable buttons enable statistics for hosts. The top usage status statistics for hosts (sources and destinations), and ports and protocols are displayed.
The fourth tab for Top 10 Users provides statistics for the Identity Firewall feature. The Identity Firewall feature provides access control based on users’ identities. You can configure access rules and security policies based on user names and user groups name rather than through source IP addresses. The ASA provides this feature by accessing an IP-user mapping database.
The Top 10 Users tab displays data only when you have configured the Identity Firewall feature in the ASA, which includes configuring these additional components—Microsoft Active Directory and Cisco Active Directory (AD) Agent. See Configuring the Identity Firewall for information.
Depending on which option you choose, the Top 10 Users tab shows statistics for received EPS packets, sent EPS packets, and sent attacks for the top 10 users. For each user (displayed as domain \ user_name), the tab displays the average EPS packet, the current EPS packet, the trigger, and total events for that user.
Enabling statistics can affect the ASA performance, depending on the type of statistics enabled. Enabling statistics for hosts affects performance in a significant way; if you have a high traffic load, you might consider enabling this type of statistics temporarily. Enabling statistics for ports, however, has a modest effect.
Top Ten Protected Servers Under SYN Attack Pane
Disabled by default. This area includes an Enable button that lets you enable the feature, or you can enable it according to the firewall configuration guide. Statistics for the top ten protected servers under attack are displayed.
For the average rate of attack, the ASA samples the data every 30 seconds over the rate interval (by default 30 minutes).
If there is more than one attacker, then “<various>” displays, followed by the last attacker IP address.
Click Detail to view statistics for all servers (up to 1000) instead of just 10 servers. You can also view history sampling data. The ASA samples the number of attacks 60 times during the rate interval, so for the default 30-minute period, statistics are collected every 60 seconds.
Top 200 Hosts Pane
Disabled by default. Shows the top 200 hosts connected through the ASA. Each entry of a host contains the IP address of the host and the number of connections initiated by the host, and is updated every 120 seconds. To enable this display, enter the hpm topnenable command.
Top Botnet Traffic Filter Hits Pane
Disabled by default. This area includes links to configure the Botnet Traffic Filter. Reports of the top ten botnet sites, ports, and infected hosts provide a snapshot of the data, and may not match the top ten items since statistics started to be collected. If you right-click an IP address, you can invoke the whois tool to learn more about the botnet site.
Cluster Dashboard Tab
The Cluster Dashboard tab shows a summary of cluster membership and resource utilization.
- Cluster Members—Shows the names and basic information about the members comprising the cluster (their management IP address, version, role in the cluster, and so on) and their health status (environment status, Health Status, and resource utilization meters).
Note In multiple context mode, if you connect ASDM to the admin context, and then change to a different context, the Management IP Address listed does not change to show the current context management IP addresses; it continues to show the admin context management IP addresses, including the main cluster IP address to which ASDM is currently connected.
- System Resource Status—Shows resource utilization (CPU and memory) across the cluster and traffic graphs, both cluster-wide and per-device.
- Traffic Status—Each tab has the following graphs.
Cluster Overall—Shows the connections per second throughout the cluster.
Per-Member Total—Shows the average connections per second for each member.
Cluster Overall—Shows the aggregated egress throughput throughout the cluster.
Per-Member Throughput—Shows the member throughput, one line per member.

Defining ASDM Preferences
This feature lets you define the behavior of certain ASDM settings.
To change various settings in ASDM, perform the following steps:
Step 1 In the main ASDM application window, choose Tools > Preferences.
The Preferences dialog box appears, with three tabs: General, Rules Table, and Syslog.
Step 2 To define your settings, click one of these tabs: the General tab to specify general preferences; the Rules Table tab to specify preferences for the Rules table; and the Syslog tab to specify the appearance of syslog messages displayed in the Home pane and to enable the display of a warning message for NetFlow-related syslog messages.
Step 3 On the General tab, specify the following:
a. Check the Warn that configuration in ASDM is out of sync with the configuration in ASA check box to be notified when the startup configuration and the running configuration are no longer in sync with each other.
b. Check the Show configuration restriction message to read-only user check box to display the following message to a read-only user at startup. This option is checked by default.
c. Check the Confirm before exiting ASDM check box to display a prompt when you try to close ASDM to confirm that you want to exit. This option is checked by default.
d. Check the Enable screen reader support (requires ASDM restart) check box to enable screen readers to work. You must restart ASDM to enable this option.
e. Check the Warn of insufficient ASA memory when ASDM loads check box to receive notification when the minimum amount of ASA memory is insufficient to run complete functionality in the ASDM application. ASDM displays the memory warning in a text banner message at bootup, displays a message in the title bar text in ASDM, and sends a syslog alert once every 24 hours.
f. Check the Preview commands before sending them to the device check box to view CLI commands generated by ASDM.
g. Check the Enable cumulative (batch) CLI delivery check box to send multiple commands in a single group to the ASA.
h. Enter the minimum amount of time in seconds for a configuration to send a timeout message. The default is 60 seconds.
i. To allow the Packet Capture Wizard to display captured packets, enter the name of the network sniffer application or click Browse to find it in the file system.
Step 4 On the Rules Table tab, specify the following:
a. Display settings let you change the way rules appear in the Rules table.
– Check the Auto-expand network and service object groups with specified prefix check box to display the network and service object groups automatically expanded based on the Auto-Expand Prefix setting.
– In the Auto-Expand Prefix field, enter the prefix of the network and service object groups to expand automatically when displayed.
– Check the Show members of network and service object groups check box to display members of network and service object groups and the group name in the Rules table. If the check box is not checked, only the group name is displayed.
– In the Limit Members To field, enter the number of network and service object groups to display. When the object group members are displayed, then only the first n members are displayed.
– Check the Show all actions for service policy rules check box to display all actions in the Rules table. When unchecked, a summary appears.
b. Deployment settings let you configure the behavior of the ASA when deploying changes to the Rules table.
– Check the Issue “clear xlate” command when deploying access lists check box to clear the NAT table when deploying new access lists. This setting ensures the access lists that are configured on the ASA are applied to all translated addresses.
c. Access Rule Hit Count Settings let you configure the frequency for which the hit counts are updated in the Access Rules table. Hit counts are applicable for explicit rules only. No hit count will be displayed for implicit rules in the Access Rules table.
– Check the Update access rule hit counts automatically check box to have the hit counts automatically updated in the Access Rules table.
– In the Update Frequency field, specify the frequency in seconds in which the hit count column is updated in the Access Rules table. Valid values are 10 - 86400 seconds.
Step 5 On the Syslog tab, specify the following:
- In the Syslog Colors area, you can customize the message display by configuring background or foreground colors for messages at each severity level. The Severity column lists each severity level by name and number. To change the background color or foreground color for messages at a specified severity level, click the corresponding column. The Pick a Color dialog box appears. Click one of the following tabs:
– On the Swatches tab, choose a color from the palette, and click OK.
– On the HSB tab, specify the H, S, and B settings, and click OK.
– On the RGB tab, specify the Red, Green, and Blue settings, and click OK.
- In the NetFlow area, to enable the display of a warning message to disable redundant syslog messages, check the Warn to disable redundant syslog messages when NetFlow action is first applied to the global service policy rule check box.
Step 6 After you have specified settings on these three tabs, click OK to save your settings and close the Preferences dialog box.
Note Each time that you check or uncheck a preferences setting, the change is saved to the.conf file and becomes available to all the other ASDM sessions running on the workstation at the time. You must restart ASDM for all changes to take effect.
Using the ASDM Assistant
The ASDM Assistant tool lets you search and view useful ASDM procedural help about certain tasks.

Step 3 Click any links that appear in the Search Results and Features sections to obtain more details.
Enabling History Metrics
The Configuration > Device Management > Advanced > History Metrics pane lets you configure the adaptive ASA to keep a history of various statistics, which ASDM can display on any Graph/Table. If you do not enable history metrics, you can only monitor statistics in real time. Enabling history metrics lets you view statistics graphs from the last 10 minutes, 60 minutes, 12 hours, and 5 days.
To configure history metrics, perform the following steps:
Step 1 Choose Configuration > Device Management > Advanced > History Metrics.
The History Metrics pane appears.
Step 2 Check the ASDM History Metrics check box to enable history metrics, and then click Apply.
Unsupported Commands
ASDM supports almost all commands available for the adaptive ASA, but ASDM ignores some commands in an existing configuration. Most of these commands can remain in your configuration; see Tools > Show Commands Ignored by ASDM on Device for more information.
This section includes the following topics:
- Ignored and View-Only Commands
- Effects of Unsupported Commands
- Discontinuous Subnet Masks Not Supported
- Interactive User Commands Not Supported by the ASDM CLI Tool
Ignored and View-Only Commands
Table 5-5 lists commands that ASDM supports in the configuration when added through the CLI, but that cannot be added or edited in ASDM. If ASDM ignores the command, it does not appear in the ASDM GUI at all. If the command is view-only, then it appears in the GUI, but you cannot edit it.
Effects of Unsupported Commands
If ASDM loads an existing running configuration and finds other unsupported commands, ASDM operation is unaffected. To view the unsupported commands, choose Tools > Show Commands Ignored by ASDM on Device.
Discontinuous Subnet Masks Not Supported
ASDM does not support discontinuous subnet masks such as 255.255.0.255. For example, you cannot use the following:
Interactive User Commands Not Supported by the ASDM CLI Tool
The ASDM CLI tool does not support interactive user commands. If you enter a CLI command that requires interactive confirmation, ASDM prompts you to enter “[yes/no]” but does not recognize your input. ASDM then times out waiting for your response.
1. Choose Tools > Command Line Interface.
2. Enter the crypto key generate rsa command.
ASDM generates the default 1024-bit RSA key.
3. Enter the crypto key generate rsa command again.
Instead of regenerating the RSA keys by overwriting the previous one, ASDM displays the following error:
- You can configure most commands that require user interaction by means of the ASDM panes.
- For CLI commands that have a noconfirm option, use this option when entering the CLI command. For example:
