Information About D6 Discovery Protocol
The following sections provide more information about the D6 discovery protocol.
Overview of the D6 Discovery Protocol
You should configure the D6 discovery protocol for each Logical Edge Device (LED). When the LED is set to active, the D6 discovery protocol establishes a connection with the ERM and sends out the below information to the ERM:
-
Streaming Zone—The streaming zone within which the LED operates. You must configure a streaming zone.
-
Component Name—The name of the LED for the ERM to associate the subsequent update messages. You must configure a component name.
-
Vendor Specific String—Contains the vendor and mode names. When using PME encryption, the D6 vendor-string must be changed to something other than “Cisco”, for example, vendor-string “CBR8”. For PowerKEY encryption, the vendor-string is an optional configuration and the default value is “Cisco CBR8k”.
Edge inputs are configured under the LED or the Virtual Carrier Groups (VCG) associated to the LEDs. For each edge input, the following information is sent to the ERM:
-
IP Address—As configured under LED or VCG associated to the LED.
-
Port—As configured for each input port.
-
Max Bandwidth—As configured under the input group of D6 configuration. The defaults value is 20 Gbps.
-
Group name—As configured under the input group of D6 configuration. The default value is the LED name if the input port is configured under LED or the VCG name if the input port is configured under VCG
For every QAM (RF channel) configured under the LED through VCG, the following information is sent to the ERM:
-
Route—Route state as Reachable, if a QAM is added, Withdrawn, if a QAM is removed.
-
QAM Group Name—As configured for the VCG name.
-
QAM Name—Streaming zone.tsid (for example, 1234.100). Streaming zone is configured under D6 and TSID is configured under VCG for every QAM.
-
Total Bandwidth— Total bandwidth of the QAM.
-
QAM Parameters: -
Frequency—Center frequency of this carrier
-
Interleaver
-
Modulation Mode
-
TSID
-
Annex—A/B
-
Channel Width - 6 MHz/8 MHz
-
-
UDP Map—This is sent only for the table-based session configurations. A table of the UDP port for each MPEG program number is sent out through this.
-
Output Port—The configured VCG ID is sent out as the Output Port ID.
The configuration updates are sent to the ERM through different update messages. D6 also exchanges the keep alive messages periodically to retain the TCP connection with the ERM.
Prerequisites for D6 Discovery Protocol
- As the D6 configuration is
placed under the LED protocol configuration, you must complete the following
configurations before configuring the D6 discovery protocol:
-
Service Distribution Group (SDG)
-
Virtual Carrier Group (VCG)
-
Bind VCG to SDG
-
Logical Edge Device (LED)
-
Associate VCG to LED
-
-
Since the D6 discovery protocol requires a management IP for communicating with the external server, ensure that the virtual port group interface is configured and the same is set for the management interface under cable video. Follow the procedure below to configure a virtual port group: configure terminal cable video mgmt-intf VirtualPortGroup virtual port group id
-
If you must configure a Fully Qualified Domain Name (FQDN) for the D6 server configuration instead of the IP address, then ensure that you configure the name server before configuring the D6 discovery protocol. Use the show ip dns view command to see if the DNS name server is configured. Follow the procedure below to configure the name server: ip name-server ip address ip domain name domain name ip domain lookup
