We suggest you use static addressing instead. Apply the changes? Restarting network services Do you want to continue with upgrade? Press 'Enter' to reboot the system.
Depending on available system resources CPU, memory, and disk , this may take 30 minutes or more to complete. Manage the device locally? After upgrade, the health monitor will alert if you lower the memory allocation. These new memory requirements enforce uniform requirements across all virtual environments, improve performance, and allow you to take advantage of new features and functionality.
We recommend you do not decrease the default settings. As of the Version 6. You cannot create new instances using them, even for earlier versions. You can continue running existing instances. From c3. From c4. We also offer a c5.
Stop the instance before you resize. Note that when you do this, data on the instance store volume is lost, so migrate your instance store-backed instance first.
Additionally, if your management interface does not have an Elastic IP address, its public IP address is released. For instructions, see the documentation on changing your instance type in the AWS user guide for Linux instances. Use the Azure portal or PowerShell. You do not need to stop the instance before you resize, but stopping may reveal additional sizes. Resizing restarts a running virtual machine. For instructions, see the Azure documentation on resizing a Windows VM.
Version 6. For Firepower series devices, you must power cycle the device after you upgrade to Version 6. The automatic reboot is not sufficient.
Other supported devices do not require the power cycle. All historical report data is removed during the upgrade due to a database schema change. After the upgrade, you cannot query historical data, nor view historical data in dashboards. Talos Intelligence Group has introduced new categories and renamed reputations to classify and filter URLs.
Also new are the concepts of uncategorized and reputationless URLs, although rule configuration options stay the same:.
You can filter Uncategorized URLs but you cannot further constrain by reputation. These rules will match all uncategorized URLs, regardless of reputation.
Note that there is no such thing as an Untrusted rule with no category. Otherwise uncategorized URLs with an Untrusted reputation are automatically assigned to the new Malicious Sites threat category. You cannot filter reputationless URLs. There is no option in the rule editor for 'no reputation.
These URLs must also be constrained by category. The following table summarizes the changes on upgrade. Although they are designed for minimal impact and will not prevent post-upgrade deploy for most customers, we strongly recommend you review these release notes and your current URL filtering configuration. Careful planning and preparation can help you avoid missteps, as well as reduce the time you spend troubleshooting post-upgrade. The upgrade modifies URL rules to use the nearest equivalents in the new category set, in the following policies:.
These changes may create redundant or preempted rules, which can slow performance. If your configuration includes merged categories, you may experience minor changes to the URLs that are allowed or blocked.
The upgrade clears the URL cache, which contains results that the system previously looked up in the cloud. Your users may temporarily experience slightly longer access times for URLs that are not in the local data set. For already-logged events, the upgrade labels any associated URL category and reputation information as Legacy. These legacy events will age out of the database over time.
The system must be able to communicate with the following Cisco resources after the upgrade:. Understand the upcoming changes. Examine your current URL filtering configuration and determine what post-upgrade actions you will need to take see the next section. You may want to modify URL rules that use deprecated categories now. Otherwise, rules that use them will prevent deploy after the upgrade. In FMC deployments, we recommend you generate an access control policy report , which provides details on the policy's current saved configuration, including access control rules and rules in subordinate policies such as SSL.
For each URL rule, you can see the current categories, reputations, and associated rule actions. After upgrade, you should reexamine your URL filtering configuration and take the following actions as soon as possible.
Depending on deployment type and the changes made by the upgrade, some — but not all — issues may be marked in the GUI. The upgrade does not modify URL rules that use deprecated categories.
Rules that use them will prevent deploy. On the FMC, these new categories are not marked after this upgrade, but Talos may add additional categories in the future. When that happens, new categories are marked. Each rule that included any of the affected categories now include all of the affected categories. If the original categories were associated with different reputations, the new rule is associated with the broader, more inclusive reputation. Depending on what changed and how your platform handles rule warnings, changes may be marked.
For example, the FMC marks wholly redundant and wholly preempted rules, but not rules that have partial overlap. The upgrade replaces each old, single category in URL rules with all the new categories that map to the old one. This will not change the way you filter URLs, but you can modify affected rules to take advantage of the new granularity. Understand which categories were renamed or are unchanged. Evaluate how you handle uncategorized and reputationless URLs.
Even though it is now possible to have uncategorized and reputationless URLs, you cannot still cannot filter uncategorized URLs by reputation, nor can you filter reputationless URLs. Make sure that rules that filter by the Uncategorized category, or by Any reputation, will behave as you expect. When you examine your URL filtering configuration before the upgrade, determine which of the following scenarios and guidelines apply to you.
This will ensure that your post-upgrade configuration is as you expect, and that you can take quick action to resolve any issues. When considering rules that include the same category, remember that traffic matches the first rule in the list that includes the condition. Merging categories in a single rule will merge into a single category in the rule. Merging categories in different rules will result in separate rules with the same category in each rule after the merge. How you choose to resolve this situation depends on the rule order, on the actions and reputation levels associated with the rules, on the other URL categories included in the rule, and on the non-URL conditions that are included in the rule.
If merged categories in different rules were associated with different actions, then after merge you may have two or more rules with different actions for the same category. If a single rule includes categories that were associated with different reputation levels before merging, the merged category will be associated with the more inclusive reputation level.
For example, if Category A was associated in a particular rule with Any reputation and Category B was associated in the same rule with reputation level 3 - Benign sites with security risks , then after merge Category AB in that rule will be associated with Any reputation. After merge, different rules may have the same category associated with different actions and reputation levels.
Redundant rules may not be exact duplicates, but they may no longer match traffic if another rule earlier in the rule order matches instead. On the FMC, rules with an identical category and reputation will show a warning. However, these warnings will not indicate rules that include the same category but a different reputation. Caution: Consider all conditions in the rule when determining how to resolve duplicate or redundant categories.
Therefore, if a particular category is duplicated after merge, you may want to modify rather than delete these rules. Rules with merged URL categories may also include other rule conditions, such as application conditions. In two-rule examples, Rule 1 comes before Rule 2. The specific result varies by the rules' order in the list, reputation levels, and associated actions.
You should also consider all other conditions in the rule when determining how to resolve any redundancy. Rule 2 will never match traffic, and will display a warning indicator if you show warnings after merge, because both category and reputation are the same. All the best Loris.
