This chapter contains the following sections:
Before you can begin managing your networks, you must create a domain. A domain is a collection of multicast routers, Layer 2 (L2) devices, video probe, and VidMon devices. Multiple domains can exist, and routers can belong to multiple domains. Using Domain Management, you can create and edit domains.
You can create a domain by in two ways:
•By adding a domain and setting the domain configuration options on the System Configuration page.
See Creating a Domain.
•By importing an existing domain configuration from a comma-separated value (CSV) file.
See Importing a Domain.
To create a domain:
Step 1 From the Multicast Manager menu, select System Configuration.
Step 2 Select Domain Management.
The Domain Management Summary page appears, as shown in Figure 4-1.
Figure 4-1 Domain Management Summary Page
The list of domains shows any domains that have been defined previously and indicates whether they have been discovered. You can discover undiscovered domains by clicking the Start Discovery link for the domain, and you can rediscover previously discovered domains by clicking the Re-discovery link for the domain.
Step 3 To add a new domain, click the Add button and from the drop-down list, choose By Domain.
Step 4 To edit an existing domain, check the check box for the desired domain listing and click Edit.
If you click Add and choose By Domain or click Edit, the System Configuration page appears, as shown in Figure 4-2.
Figure 4-2 System Configuration Page
The System Configuration page contains the following fields:
Step 5 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 new domain name appears in the list of domains on the Domain Management page.
Step 6 If you want to discover the devices in the domain at this time, click on the Start Discovery link in the table row for the domain.
If you click on Start Discovery, the Multicast Discovery page appears, which allows you to enter parameters for the discovery process.
Step 7 For information on the Multicast Discovery page and discovering a domain, see Multicast Discovery, page 6-1.
Rediscovering a Domain
On the Domain Management domains, domains that have been previously discovered have a Re-discovery link in the table row for the domain.
If you want to rediscover the domain, click the Re-discovery link for the domain.
If you click on Start Discovery, the Multicast Discovery page appears, which allows you to enter parameters for the discovery process.
For information on the Multicast Discovery page and discovering a domain, see Multicast Discovery, page 6-1.
To import a domain:
Step 1 From the Multicast Manager menu, select System Configuration.
Step 2 Select Domain Management.
Step 3 From the drop-down list in the Add field, choose By Import button to import a new domain.
Step 4 Click the Browse button to locate the CSV file that contains the domain information to import.
Step 5 Click the Upload button.
Note After the upload process is initiated, the System Configuration page populates with information.
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 On the top part of the Global Polling Configuration page, configure polling intervals and run times for each type of polling, as indicated in Table 4-1.
Note Setting any one of these values to less than 1 disables that specific polling feature.
Step 4 Scroll down the page to see the Trap Receiver and Global Default E-mail configuration sections of the page, shown in Figure 4-3.

Step 5 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 6 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 Mixed Signal 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 7 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 8 To add or remove e-mail addresses, use the Configure Global Default E-mail Addresses for Event Notification section. E-mail addresses are notified of SSG exceptions and threshold related events. The e-mail addresses specified here are used only if domain-specific e-mail addresses are not specified. Domain-specific email addresses are specified from the Domain Trap/Email Polling Configuration page.
