Description
If keepalive messages have been enabled for an IP multicast group,
using the
Multicast group IP address for the DSG stream.
Source IP address for the DSG stream. If an asterisk (*) appears as
the source IP address, it indicates that the source IP address is
0.0.0.0, which allows any IP address as the source IP address.
Well-known MAC address used for the DSG tunnel. If you
configured the DSG tunnel with a MAC address of 0000.0000.0000
using the
that the CMTS derived using the MAC to IP multicast addressing
mapping that is specified in
Cable interface on which this DSG tunnel is configured.
Number of times that this particular DSG tunnel mapping has been
used to resolve the well-known MAC address from the tunnel's
group address. This can be used as a very rough approximation of
the number set-top boxes (STBs) that have been mapped to this
DSG tunnel since the last time the counter was cleared.
Note
Number of packets transmitted over the DSG tunnel.
Name for the Conditional Access (CA) vendor that owns this tunnel.
Number of packets received by the multicast group. This counter
includes all interfaces that are receiving traffic for the multicast
group. The field is not shown when an interface is shut down, but
the counter continues to increase as long as the multicast group is
receiving traffic. When the interface is reenabled, the counter shows
the latest number of packets received.
