Web Agent Procedure

To display the multicast forwarding cache Web page:

  1. In the navigation pane, expand the Routing > DVMRP folders, and then click Multicast Forwarding Cache.

    2. The Multicast Forwarding Cache Web page is displayed in the content pane. See Figure�125.

Figure�125:�Multicast Forwarding Cache Web Page


  1. To modify the Multicast Forwarding Table:
  2. See Table�88 for an explanation of the Multicast Forwarding Cache parameters:

Table�88:�Multicast Forwarding Cache Parameters �
Parameter
Description
Select
Selection of the multicast forwarding cache.
Destination Group Address
Destination group address of the multicast transmission.
Source SubNetwork
Subnet from which the flow is coming.
Source Address Mask
Subnet mask associated with the DVMRP source subnetwork.
Upstream Interface
Local interface which is receiving this flow.
Upstream Neighbor (Router) Address
IP address of the upstream neighbor (router).
Invalid Flows From Upstream
Number of invalid flows received from the upstream neighbor.
Packets Forwarded Through Cache Entry
Number of packets successfully forwarded in the CPU (supervisor module) for this flow.
Upstream Interface is Pruned
Router that is sending prunes to the upstream neighbor. Allows you to open the DVMRP Upstream Prune Information Web page.
Next Pruned Downstream Interface to Timeout
Next interface that is currently pruned which will be grafted back.
Downstream Interface(s)
Number of downstream interfaces. Allows you to open the DVMRP Downstream Links Web page.
Upstream Source(s)
Number of upstream interfaces. Allows you to open the Upstream Sources Web page.

  1. Select the number in the Upstream Interface is Pruned field. The Upstream Prune Information Web page is displayed.
  2. See Table�89 for an explanation of the Upstream Prune Information parameters.

�

Table�89:�Upstream Prune Information Parameters �
Parameter
Description
Destination Group Address
Destination group address of the multicast session.
Source SubNetwork
Subnet on which the DVMRP interface exists.
DVMRP Upstream Interface
Name of the upstream interface.
Interface Type
The interface type. Types include:
  • Broadcast - All traffic is forwarded through the routers. This is not a tunnel and does not require encapsulation.
  • IPIP Tunnel - All multicast traffic (data and protocol messages) on this interface is encapsulated in IP unicast packets with the protocol set to IPIP (IP in IP).
  • Non-Encapsulated Tunnel - All multicast data traffic on this interface is IPIP encapsulated, but the protocol messages are simple unicast.
Interface is Pruned
Status of whether the interface has been pruned.
Prune Expiration Time in sec
Time (in seconds) that the interface times out waiting for the prune message to expire.

  1. Select the number in the Downstream Interface(s) field. The DVMRP Downstream Link(s) Web page is displayed.
  2. See Table�90 for an explanation of the DVMRP Downstream Link parameters.

Table�90:�DVMRP Downstream Link Parameters �
Parameter
Description
Destination Group Address
Destination group address.
Source SubNetwork
Source subnetwork.
DVMRP Downstream Interface
DVMRP Downstream interface.
Interface Type
Interface type. Types include:
  • Broadcast - All traffic is forwarded through the routers. This is not a tunnel and does not require encapsulation.
  • IPIP Tunnel - All multicast traffic (data and protocol messages) on this interface is encapsulated in IP unicast packets with the protocol set to IPIP (IP in IP).
  • Non-Encapsulated Tunnel - All multicast data traffic on this interface is IPIP encapsulated, but the protocol messages are simple unicast.
Interface is Pruned
Status of whether the interface has been pruned.
Prune Expiration in (sec)
Time (in seconds) that the interface times out waiting for the prune message to expire.

  1. Select the number in the Upstream Source(s) field. The DVMRP Upstream Source(s) Web page is displayed.
  2. See Table�91 for an explanation of the DVMRP Upstream Source parameters.

Table�91:�DVMRP Upstream Source Parameters �
Parameter
Description
Destination Group Address
Destination group address for the upstream interface.
Flow Source Address
Host source address for the upstream flow.
Flow Upstream Interface
Name of the flow source interface.
Payload Protocol Type
Protocol type for the payload.
Source Port Number
Source port number.
Destination Port Number
Destination port number.
