ANCP Guidelines and Restrictions
ANCP Guidelines and Restrictions
When using (or configuring) ANCP, consider these guidelines and restrictions:
• Entering a shut command on a port removes ANCP activated multicast streams from the port. They
must be reactivated by the ANCP server.
• Entering a suspend or shut command on a VLAN removes ANCP-activated multicast streams from
the VLAN.
• Deleting a VLAN removes ANCP-activated multicast streams from the VLAN.
• If a port enters the errdisable or blocked state, ANCP-activated multicast streams are removed from
the port.
• Disabling IGMP snooping globally or per-VLAN might disrupt ANCP client functionality.
• An ANCP client does not account for the Layer 3 interface state changes (if PIM interface at
Layer 3 shuts down, ANCP does not remove the streams). When a PIM interface is running again,
multicast streams are received by subscribers.
