Domain Management
Creating a Domain
Before you can begin managing your networks, you must create a domain. A domain is a collection of multicast routers, Layer 2 (L2) devices, and video probes. Multiple domains can exist, and routers can belong to multiple domains. Using Domain Management, you can create and edit domains.
To create a domain:
Step 1 From the Multicast Manager menu, select System Configuration.
Step 2 Select Domain Management.
Figure 2-1 Domain Management Summary Page
Step 3 Click the Add button to add a new domain.
Note To edit an existing domain, check the check box for the desired domain listing and click Edit.
Step 4 Complete the fields in the System Configuration page and click Save, Reset to clear the data fields and create the new domain. Click Cancel to exit without creating a domain.
The System Configuration page contains the following fields:
Field
|
Description
|
Management Domain
|
A management domain is defined as a contiguous group of PIM neighbors sharing the same SNMP community string.
|
Read Only
|
SNMP read-only community string. Verify the string.
|
Read Write
|
SNMP read-write community string. This is required for retrieving and validating device configurations. Verify the string.
|
SNMP Timeout
|
Retry period if the node does not respond. Default value is 0.8.
|
SNMP Retries
|
Number of retries to contact a node before issuing a timeout. Default value is 2.
|
TFTP Server
|
TFTP server IP address. Default is the IP address of the Cisco Multicast Manager server.
|
VTY Password
|
The VTY password is required if you want to issue to show commands from the application. Certain features, such as querying Layer 2 switches, also require this. If TACACS is being used, then a username and password can be supplied instead of the VTY password. Verify the password.
|
Enable Password
|
Enter the password and verify the password.
|
TACACS/RADIUS Username
|
If you are using TACACS/RADIUS, you can enter a username here. See VTY Password above.
Note If you enter a TACACS/RADIUS username and password here, the application will use these values regardless of who is logged in. Users can also enter their own username and password when issuing show commands.
|
TACACS/RADIUS Password
|
If you are using TACACS/RADIUS, you can enter a password here. See VTY Password above.
Note If you enter a TACACS/RADIUS username and password here, the application will use these values regardless of who is logged in. Users can also enter their own username and password when issuing show commands.
|
CLI Access
|
Select either Telnet or SSH.
|
Threshold Polling
|
Check the check box for enabling CLI mode of threshold polling. The routers being polled are the ones for which Cisco IOS and chassis information were configured in the rmspollcli.conf file.
|
Cache TACACS Info
|
Check the check box to cache the TACACS username and password until the browser is closed. This eliminates the need to enter the username and password each time that you issue a router command from the application.
|
Resolve Addresses
|
Performs Domain Name System (DNS) lookups on all sources found. The DNS name appears alongside the IP address on the "Show All Groups" screen. If the server is not configured for DNS, then do not check the box. If the box is checked, you may receive a slower response, because the application is trying to resolve names. We recommend disabling this option if your network contains a large number of source and groups (S,Gs). The Resolve Addresses option also causes discovery to do a reverse DNS lookup on a device name. The IP address returned by DNS is then used for management purposes. Otherwise, the IP address by which the device is found is used for management purposes.
|
Use Cache
|
Some networks contain thousands of S,Gs. During discovery, CMM caches all the S,Gs found in the RPs. If this box is checked, CMM reads the S,G cache when showing lists of sources and groups, rather then retrieving them again from the RPs in the network. The cache can also be refreshed manually by clicking the Reload Cache button in the Multicast Diagnostics window. This button appears only if you have the Use Cache option selected. We highly recommend that you use the S,G cache option. If there are no RPs in the domain being discovered, then the S,G cache is created by querying all the devices that have been discovered, as would be the case in a PIM Dense-Mode network. In this case, the S,G cache is updated only when you click the Reload Cache button.

Importing a Domain
To import a domain:
Step 1 From the Multicast Manager menu, select System Configuration.
Step 2 Select Domain Management.
Step 3 Click the Add > By Import button to import a new domain.
Step 4 Click the Browse button to locate a file.
Step 5 Click the Upload button.
Note After the upload process is initiated, the table populates with information.
Global Polling Configuration
You can configure each polling element to start and stop at specific times. Each element also has its own polling interval. You can configure these values through the Global Polling Configuration page.
Note You must restart the polling daemon after making changes on this page. Click the Restart button in the Polling Actions field to restart polling. Click the Stop button to stop polling.
To configure global polling:
Step 1 From the Multicast Manager menu, select System Configuration.
Step 2 Select Global Polling Configuration.
The Global Polling Configuration page appears.
Step 3 The following table describes the fields and selections on the Global Polling Configuration page:
Note Setting any one of these values to less than 1 disables that specific polling feature.
Field or Button
|
Description
|
Default Run Times—Use Defaults
|
Selecting the Use Defaults check box sets all the start and stop times, and days to the default values.
|
DR Polling Interval
|
Checks the status of all DRs in the network. If a user changes a DR, an SNMP trap is sent.
|
Layer 2 Polling Interval
|
Time between polling of the Layer 2 ports.
|
RP Cache Polling interval
|
RP Polling queries the RP configured in Specific Multicast Polling and looks for new forwarding entries (S,G) added/removed.
|
RP Status Polling Interval
|
RP Status Polling queries the sysUpTime of the RPs configured on the RP Polling Configuration page.
The purpose of this query is to report availability of the RPs. If the RP responds, an rpReachable trap is sent. If the RP does not respond, an rpUnreachable trap is sent. Since at least one of these traps is sent at each polling interval, you can also use them to ensure that the polling daemon is up and running.
|
RPF Failure Polling Interval
|
Time interval at which each router will be polled for each source and group configured, to check the number of RPF failures.
|
Threshold Polling Interval
|
Time interval that each router will be polled for the existence of each source and group configured, and CMM will ensure that no thresholds are exceeded.
|
Multicast Topology Polling Interval
|
Topology polling queries the sysUpTime of each router in the multicast domain to see if it has been reloaded. If it has, the polling daemon launches a Single Router Discovery of that device in the background, to ensure that the SNMP ifIndexes have not changed.
|
Tree Polling Interval
|
Time interval at which the monitored trees are drawn and compared with their baselines.
|
Interface Polling Interval
|
Time interval where the percent of multicast bandwidth per interface is compared to the thresholds.
|
Health Polling Interval
|
Time interval at which the configured health checks are scheduled to run.
|
Selective Source Polling Intervals
|
Time intervals set to the source and group to be monitored for the particular time and day. The time interval configured should not be overlapping for the same source and group.
|
Heart Beat Polling Interval
|
Time interval at which the heart beat trap is sent to the northbound application. These traps serve as the notification about the health of the polling daemon.
|
MVPN Polling Interval
|
Frequency MVPN data and whose entries would be polled PE devices.
|
Video Probe Polling
|
Time interval that the video probes are polled for MDI values.
|
Video Probe Clear Timer
|
Interval that Cisco Multicast Manager changes a yellow warning indicator to a green OK indicator.
|
Save
|
Sets the values that you have entered.

Figure 2-2 Trap Receiver/Email Polling Configuration
Step 4 To enable or disable the continuous sending of PPS threshold traps, use the Enable Rising/Falling and Normalized Traps for Thresholds section:
•If the Rising/Falling option is not checked (disabled), traps are sent whenever the PPS rate for a monitored S,G exceeds specified thresholds.
•If the Rising/Falling option is checked (enabled), a trap is sent only when the PPS rate initially exceeds the high or low threshold. After the PPS rate returns to the specified range, a normalized threshold trap is sent.
•Because SNMP v1 traps are sent unreliably, you can set the Trap-Repeat option to allow the initial and normalized traps to be sent from 1 to 5 times when an event occurs.
Step 5 To add trap receivers, complete these steps:
a. Go to the Configure Global Default SNMP Trap Receivers section.
b. Enter the IP address for the trap receiver.
c. Click the Add button.
The IP address appears in the Configured Trap Receivers list.
d. If you want to forward MixedSignal traps northbound to another application, check the Forward Mixed Signal Traps check box.
Note If you enable the Mixed Signal trap forwarding option, the Mixed Signal traps are not displayed on the trap viewer page.
Note The SNMP trap receivers specified here are only used if domain-specific SNMP trap receivers are not specified. Domain-specific trap receivers are specified from the Domain Trap/Email Polling Configuration page.
e. Click the Save button.
A message appears instructing you to start the snmptrapd processes to cause the changes in Mixed Signal trap forwarding to take effect.
Step 6 To remove trap receivers, click the IP address of the trap receiver that you want to remove and then click the Remove button, then click Save.
Step 7 To add or remove email addresses, use the Configure Global Default Email Addresses for Event Notification section. Email addresses are notified of SSG exceptions and threshold and existence events. The email addresses specified here are used only if domain-specific email addresses are not specified. Domain-specific email addresses are specified from the Domain Trap/Email Polling Configuration page.
