These Web UI pages provide a view into central configuration of the regional cluster. These pages are available only to administrators assigned the central-cfg-admin role. This role can centrally manage local server clusters and routers, virtual private network (VPN) properties, DHCP scope templates, policies, client-classes, and failover server pairs.

• View the server cluster tree
• Manage the local server clusters
• View the router interface configuration (RIC) server tree
• Manage routers
• View the regional replica data
• Manage virtual private networks (VPNs)
• Manage DHCP scope templates
• Manage DHCP policies
• Manage DHCP client-classes
• Manage DHCP failover server pairs

This page lists the local server clusters. It is available only to administrators assigned the central-cfg-admin role. Each server cluster forms a top level tree node, and is expandable to show the child nodes of individual local cluster servers (DNS, DHCP, TFTP, CCM/MCD, and server agent). To expand the tree, click the plus sign (+) to the left of the cluster name.

You can click each cluster name to open its Edit Server Cluster page. You can also click the Go Local icon () to open the Manage Servers page in the local cluster's Web UI. (NOTE: If authentication to the local cluster fails, you first get the login screen for the local Web UI.) Click the Go Regional icon () at the top of the local cluster Manage Servers page to return to the regional cluster Web UI.

NOTE: If you log out of the local cluster after connecting to it, you return to the regional cluster.

The columns on this page are:

Column	Description
Name	Name of the cluster. These clusters are created on the Add Server Cluster page. Once expanded (using +), the cluster list shows the local servers on the cluster. Edit the cluster by clicking the cluster name to open the Edit Server Cluster page. You can also view the related servers for a DHCP server by clicking the Related Servers icon () to open the List Related Servers for DHCP Server page.
Connect	Click the Go Local icon () to access the local cluster's Manage Servers page (if you have single sign-on privileges) or the login page (if you do not). Click the Go Regional icon () at the top of the local cluster Manage Servers page to return to the regional cluster Web UI.
Type	Cluster or Server.
IP Address	IP address of the cluster.
SCP Port	SCP port of the cluster, usually 1234.

Refresh the list whenever possible. There are four additional functions on this page:

• Resynchronize () -- Click this icon to update the regional CCM database with the latest data from the local cluster.

  Synchronization is configuring a regional and local cluster so that they can work together in a unified fashion. The main steps of synchronization are:

  1. Copy the list of local servers to the regional cluster.
  2. Establish a shared secret so that single sign-on can work.

  Synchronization occurs once when setting up a local cluster. If you get an error message during synchronization, check that the local cluster is running properly or has the proper base licenses.

• Replicate Data () -- Click this icon to initialize or update data replication on the regional server from the local clusters.

  Replication is copying the authoritative data from a master server to a replica database. These include zones, scopes, address blocks, subnets, policies, scope templates, client-classes, and VPNs. The main steps in this operation are:

  1. Copy the current data from the master database if the replica database does not have data for the master. This usually occurs once.
  2. Copy any changes made at the master database since the last replication. This usually occurs on a periodic basis, but you can force it using this function.

• Poll Subnet Utilization () -- Click this icon to poll subnet utilization data from the local clusters. (This function appears only if you have address space privileges.) Note that the local DHCP server has new data to report only at each collect-addr-util-interval, so once the data is up to date for a collection period, subsequent polling actions within that interval return no new records, even if address utilization changed on the local server. It is best to wait until after the collection interval to repoll for subnet utilization data.

• Poll Lease History () -- Click this icon to poll lease history data from the local clusters. (This function appears only if you have address space privileges.)

This page lists the local server clusters added to the regional cluster. This is core functionality of the central-cfg-admin role. You can add clusters from this page. You can also click the cluster name to open an Edit Server Cluster page.

If you have single sign-on privileges to the local cluster, click the Go Local icon () to access the local cluster's Manage Servers page. If you do not have these privileges, you access the local cluster's login page. Click the Go Regional icon () at the top of the local cluster Manage Servers page to return to the regional cluster Web UI.

There are four additional functions on this page:

• Resynchronize () -- Click this icon to update the regional CCM database with the latest data from the local cluster.

  Synchronization is configuring a regional and local cluster so that they can work together in a unified fashion. The main steps of synchronization are:

  1. Copy the list of local servers to the regional cluster.
  2. Establish a shared secret so that single sign-on can work.

  Synchronization occurs once when setting up a local cluster.

• Replicate Data () -- Click this icon to initialize or update data replication on the regional server from the local clusters.

  Replication is copying the authoritative data from a master server to a replica database. These include zones, scopes, address blocks, subnets, policies, scope templates, client-classes, and VPNs. The main steps in this operation are:

  1. Copy the current data from the master database if the replica database does not have data for the master. This usually occurs once.
  2. Copy any changes made at the master database since the last replication. This usually occurs on a periodic basis, but you can force it using this function.

• Poll Subnet Utilization () -- Click this icon to poll subnet utilization data from the local clusters. (This function appears only if you have address space privileges.) Note that the local DHCP server has new data to report only at each collect-addr-util-interval, so once the data is up to date for a collection period, subsequent polling actions within that interval return no new records, even if address utilization changed on the local server. It is best to wait until after the collection interval to repoll for subnet utilization data.

• Poll Lease History () -- Click this icon to poll lease history data from the local clusters. (This function appears only if you have address space privileges.)

Click Add Cluster to open the Add Server Cluster page. You can also delete clusters on this page.

Use this page to add local server clusters to the regional cluster.

The attributes on this page are:

The additional cluster attributes that you can set, such as HTTP ports and polling, appear in separate categories on this page. Note that using the HTTPS port is disabled by default. Click any attribute name to open a help window describing it.

The replication settings are for setting the interval and time offsets for data replication of the local clusters on the regional cluster. By default, the CCM server polls the replica data as a background process every four hours. If the local and regional cluster servers are separated by time zones, use the poll-replica-offset value to account for it. The replication-initialized value shows if replication is initialized once the clusters are synchronized.

For details on the subnet utilization and lease history polling attributes, see Querying Subnet Utilization and Querying Lease History.

When you finish, click Add Cluster, or Cancel to cancel. Adding clusters effectively synchronizes the local cluster server and registers the local CCM servers for single sign-on. You return to the List Server Clusters page. Refresh that page before choosing any items for editing.

This page is the edit version of the Add Server Cluster page. You can also unset fields on this page. Click Modify Cluster to effect the changes, or Cancel to cancel. You return to the List Server Clusters page. Refresh that page before choosing any items for editing.

This page lists the routers accessible from the regional cluster. This function is available only if the router license is entered, and it is accessible only by administrators assigned the ric-management subrole of a central-cfg-admin role.

The tree levels are the routers, their parent router interfaces, and any child interfaces. Parent/child relationships can be either physical/virtual (as in Cable2/0 and Cable2/0.1) or master/slave (as in the case of router interface bundling, where the bundle is identified by one of the interfaces).

The routers must be one of the Cisco routers in the family Ubr72xx or Ubr10k.

At the regional cluster, this page displays the DHCP failover server pairs created at the local clusters and discovered upon replication, or created on the regional server to be pushed down to the local cluster. This and the related pages are available only to regional administrators assigned the dhcp-management subrole of the central-cfg-admin role.

Note that failover pairs show up in this list if they were set up using the server or scope failover attributes when editing the local cluster DHCP server attributes or creating or editing a local cluster scope. Be sure to set at least the following on the Edit DHCP Server or Edit DHCP Scope page, then reload the DHCP server:

• Failover to on for the DHCP server, or use-server-settings (if set to on for the server) or scope-enabled for the scope.

• Main Server and Backup Server IP addresses on the DHCP server or scope.

At the regional cluster, you can name the failover pair any unique string.

• To add a failover pair, click Add Failover Pair to open the Add Failover Pair page.

• To edit a failover pair, click its name in the list. This opens the Edit Failover Pair page.

• To view the related servers for a main or backup DHCP server, click the Related Servers icon () to open the List Related Servers for DHCP Server page.

At the regional cluster, this page appears when you click Add Failover Pair on the List Failover Pairs page. The following table describes the attributes to set:

You can set additional attributes in the Additional Attributes section by expanding the section and adding values to the desired attributes. Click an attribute name to open a help window describing the attribute. Some of these attributes relate to polling subnet utilization and lease history data, including whether to poll these first from the main or backup server. The server-default attribute is set by default to make this a server-level failover pair.

When finished, click Add Failover Pair, or Cancel to cancel. When you click Add Failover Pair, you open the Report Synchronize Failover Pair page.

At the regional cluster, when you click a failover pair's name on the List Failover Pair page, you can change some of the failover pair's attributes on the Edit Failover Pair page (in read-only mode, the View Failover page). The settings correspond to those on the Add Failover Pair page.

After you modify a failover pair, synchronizing it cleans up any dangling scopes.

The optional attributes appear at the bottom of the page. For a description of each attribute, click the attribute name to open a help window.

• To unset any of the attribute values, check the box in the Unset? column next to the attribute, then click the Unset Fields button.

• To modify the failover pair, click Modify Failover. You return to the List Failover Pair page. Click the Refresh icon () on that page to refresh the database.

• To cancel your updates, click Cancel.

At the regional cluster, when you click the Start icon () in the Synchronize column of the List Failover Pairs page, the Run Synchronize Failover Pair page shows the list of properties on the two servers that should be synchronized.

When you click the Report icon () in the Report column of the List Failover Pairs page, the Report Synchronize Failover Pair page lets you run a report on what kind of properties need to be synchronized.

There are three choices on this page:

• Synchronize Subnet -- Which subnets to synchronize:
  • Use Regional Subnet -- If there is a subnet and scope template chosen for the failover pair in the regional cluster, uses this subnet.

  • Use Local DHCP -- Uses the scopes at the local cluster DHCP servers. This is the default.

• Synchronize Direction -- Which direction to synchronize:
  • Synchronize from Main to Backup. This is the default.

  • Synchronize from Backup to Main.

• Synchronize Operation -- Intensity to which you want to synchronize the failover pair. There are three values:
  • Update -- Default and least radical of the operations, generally appropriate for update synchronizations in that it has the least effect on the unique properties of the backup server. The exact DHCP attributes replaced during an Update operation are described in the DHCP Attributes Affected by an Update Synchronization topic.

  • Complete -- Appropriate for all initial synchronizations. It is more complete than an update operation, while still preserving many of the backup server's unique properties, such as are required for back office failover configurations.

  • Exact -- Appropriate for initial basic and symmetrical failover configurations, and is not appropriate for back office configurations. It makes the two servers as much as possible mirror images of each other, although it retains unique DHCP server, LDAP event services, and extension points on the backup server.

    NOTE: Do not run the Exact operation when setting up a back office failover configuration, to prevent removing the union of properties between the two main servers and the backup server.

  These operations perform different functions on each of the failover properties, as listed in the table on the page. There are essentially four functions:

  • no change -- Makes no change to the list of properties or their values on the backup server.

  • ensure -- Ensures that a copy of the main server property exists on the backup server, but does not replace its value.

  • replace -- Replaces the value of a property that the two servers have in common by that of the main server.

  • exact -- Puts an exact copy of the main server's list of properties and values on the backup server and removes the unique ones.

On this page:

• To run the synchronization based on your choices, click Run to open the View Failover Pair Sync Report page.

• To report on what change entries would apply to a synchronization, click Report.

• To cancel the synchronization or report, click Cancel.

You return to the List Failover Pairs page. Click the Refresh icon () on that page to refresh the database.

When you click Run on the Run Synchronize Failover Pair page, this page shows the synchronization report. The parts of the report are:

• What changes were made on the main DHCP server
• What changes were made on the backup DHCP server
• What change set entries were made on the regional cluster

You can show or hide the synchronization details by clicking Show Detail or Hide Detail, respectively.

To update the report, click Run Update. To return to the List Failover Pairs page, click Return to Failover Pair List.

The following table describes the DHCP attributes affected by an Update synchronization of the server pairs. For a description of each attribute, click its name on the Edit DHCP Server page.

Zone distributions simplify creating multiple zones that share the same secondary server attributes. The default zone distribution is named Default. At the regional cluster, you can add more zone distributions, and you can single sign-on to the cluster having the primary DNS server. This page lets you:

• Pull zone distributions and forward and reverse zones from the replica database of the local clusters -- Click Pull Replica Zone Data to open the Select Pull Replica Zone Data page, where you can initiate the pull operation.

• Add a zone distribution -- Click Add Zone Distribution to open the Add Zone Distribution page, where you can add the primary and secondary server information.

• Edit the zone distribution -- Click its name to open the Edit Zone Distribution page, where you add the name of the authoritative nameserver for the distribution, and change the primary and secondary server names.

• Single sign-on to the primary DNS server -- Click the Go Local icon () in the DNS Primary Server column to open the Manage Servers page in the local cluster's Web UI, or the login page if you do not have single sign-on privileges. Click the Go Regional icon () at the top of the local cluster Manage Servers page to return to the regional cluster Web UI.

• Synchronize the servers in the distribution, or run a report on the synchronization -- For each zone distribution, click the Start icon () to synchronize the servers in the zone distribution, or the Report icon () to run a report. Both of these actions open the Sync Zone Distribution page. (Note that if you delete the primary zone for the authoritative server, synchronizing deletes the secondary zone on the secondary server.)

• Synchronize the servers in all the distributions, or run a report on the synchronization -- Choose one of the synchronization methods:
  • Replace -- Replaces the zones with the same name, but retains all others.

  • Exact -- Replaces the zones with the same name, but removes all others.

  Then, click the Start icon () to synchronize the servers in the zone distribution, or the Report icon () to run a report. Both of these actions open the Sync Zone Distribution page. (Note that if you delete the primary zone for the authoritative server, synchronizing deletes the secondary zone on the secondary server.)
