Returns: XORP_OK on success, otherwise XORP_ERROR.

int  get_sg_count (const IPvX& source, const IPvX& group, SgCount& sg_count)

get_sg_count

Get MFC multicast forwarding statistics from the kernel.

Get the number of packets and bytes forwarded by a particular Multicast Forwarding Cache (MFC) entry in the kernel, and the number of packets arrived on wrong interface for that entry.

Parameters:

sourcethe MFC source address.
groupthe MFC group address.
sg_counta reference to a SgCount class to place the result: the number of packets and bytes forwarded by the particular MFC entry, and the number of packets arrived on a wrong interface.

Returns: XORP_OK on success, otherwise XORP_ERROR.

int  get_vif_count (uint16_t vif_index, VifCount& vif_count)

get_vif_count

Get interface multicast forwarding statistics from the kernel.

Get the number of packets and bytes received on, or forwarded on a particular multicast interface.

Parameters:

vif_indexthe vif index of the virtual multicast interface whose statistics we need.
vif_counta reference to a VifCount class to store the result.

Returns: XORP_OK on success, otherwise XORP_ERROR.
