If you are assigned the server-management subrole of the ccm-admin role, you can manage the Cisco Prime Network Registrar servers as follows:
- Start —Load the database and start the server.
- Stop —Stop the server.
- Reload —Stop and restart the server. (Note that you do not need to reload the server for all RR updates, even protected RR updates. For details, see the "Managing DNS Update” chapter in Cisco Prime Network Registrar 9.1 DHCP User Guide.)
- Check statistics —See the Displaying Statistics.
- View logs —See the Searching the Logs.
- Manage interfaces —See the specific protocol pages for how to manage server interfaces.
Starting and stopping a server is self-explanatory. When you reload the server, Cisco Prime Network Registrar performs three steps—stops the server, loads configuration data, and restarts the server. Only after you reload the server does it use your changes to the configuration.
The CDNS, DNS, DHCP, and SNMP servers are enabled by default to start on reboot. The TFTP server is not enabled by default to start on reboot. You can change this using [server ] type enable or disable start-on-reboot in the CLI.
If exit-on-stop attribute of DHCP, DNS, or TFTP server is enabled, then the statistics and scope utilization data only from the last start (reload) is reported while if the attribute is disabled, information across reloads is displayed.
Local Basic or Advanced and Regional Web UI
You can manage the protocol servers in the following ways depending on if you are a:
Servers from the
Operate menu to
open the Manage Servers page.
The local and regional cluster web UI access to server administration is identical, even though the available functions are different. As a regional administrator, you can check the state and health of the regional CCM server and server agent. However, you cannot stop, start, reload, or view statistics, logs, or interfaces for them.
At the local cluster, to manage the DHCP, DNS, CDNS, TFTP, or SNMP servers, select the server in the Manage Servers pane and do any of the following:
- Click the Statistics tab to view statistics for the server. (See the Displaying Statistics.)
- Click the Logs tab in the View Log column to view the log messages for the server. (See the Searching the Logs.)
- Click the Start Server button to start the server.
- Click the Stop Server button stop the server.
- Click the Restart Server button to reload the server.
Deploy menu to
open the Manage DNS Authoritative Server page.
Along with the Statistics, Startup Logs, Logs, HA DNS Server Status, Start Server, Stop Server, and Restart Server functions, you can also perform other functions when you click the Commands button to open the DNS Commands dialog box.
The server command functions are:
- Forcing all zone transfers (see the "Enabling Zone Transfers" section in Cisco Prime Network Registrar 9.1 Authoritative and Caching DNS User Guide)—Click the Run icon. This is the equivalent of dns forceXfer secondary in the CLI.
- Scavenging all zones (see the "Scavenging Dynamic Records" section in Cisco Prime Network Registrar 9.1 DHCP User Guide)—Click the Run icon. This is the equivalent of dns scavenge in the CLI.
to open the Manage DNS Caching Server page.
Along with the Statistics, Startup Logs, Logs, Start Server, Stop Server, and Restart Server functions, you can also perform other functions when you click the Commands button to open the CDNS Commands dialog box.
In Advanced and Expert modes, you can flush Caching CDNS cache and flush the resource records. Click the Commands button to execute the commands.
to open the Manage DHCP Server page.
Along with the Statistics, Startup Logs, Logs, Start Server, Stop Server, and Restart Server functions, you can also perform other functions when you click the Commands button to open the DHCP Server Commands dialog box.
This page provides the Get Leases with Limitation ID feature, to find clients that are associated through a common limitation identifier (see the "Administering Option 82 Limitation" section in Cisco Prime Network Registrar 9.1 DHCP User Guide). Enter at least the IP address of the currently active lease in the IP Address field, then click the Run icon. You can also enter the limitation ID itself in the form nn: nn: nn or as a string (" nnnn" ), in which case the IP address becomes the network in which to search. This function is the equivalent of dhcp limitationList ipaddress [limitation-id] show in the CLI.
In the CLI, the regional cluster allows CCM server management only:
- To start the server, use server type start (or simply type start ; for example, dhcp start ).
- To stop the server, use server type stop (or simply type stop ; for example, dhcp stop ). If stopping the server, it is advisable to save it first using the save command.
- To reload the server, use server type reload (or simply type reload ; for example, dhcp reload ). Cisco Prime Network Registrar stops the server you chose, loads the configuration data, and then restarts the server.
To set or show attributes for the server, use [server ] type set attribute= value or [server ] type show . For example:
nrcmd> ccm set ipaddr=192.168.50.10
