About ANCP Client
ANCP Multicast enables you to control multicast traffic on a Catalyst 4500 series switch using either
ANCP (instead of IGMP) or direct static configuration on the CLI. You can configure the switch as an
ANCP client that connects to a remote ANCP server with multicast enabled. You can then initiate joins
and leaves from that server. Use the switch in a system in which a subscriber requests that a digital right
management (DRM) server receive a given channel (multicast)
potentially through any private protocol
mechanism.
Note The ANCP client does not allow more than four multicast streams per-port per-VLAN. If a fifth join
arrives, it is rejected.
If the digital right management (DRM) server determines that a subscriber is allowed to receive a
multicast, it requests that the ANCP server sends an ANCP join command to the ANCP client
(Catalyst 4500 series switch) for the port on which the subscriber is connected.
Note IGMP snooping must be enabled on an ANCP client (Catalyst 4500 series switch) for processing
multicast commands (join, leave, leave all requests, and request for active flows report) from the ANCP
server. For information on enabling IGMP snooping. Refer to
Chapter 28, “Configuring IGMP Snooping
and Filtering, and MVR.”
