Cobalt Digital COMPASS 9220 Bidirectional ASI_MPTS Gateway - Manual (Page 37)

37 9220-UM V1.1
Once a MAC address is obtained, the 9220 will cache it for about 5 minutes, as it is usual for IP
devices. Unlike other IP devices, the 9220 will keep on using the MAC address until a response
is received, to avoid stream interruptions. If no response is received at that time, the 9220 will
raise a yellow alarm. This alarm can be seen in the IP Output Statistics tab, described in detail
below.
The current state of the 9220 current streaming ARP cache is available in the Advanced View of
the Active IP Outputs table, described above.
IP Outputs: Statistics Tab
The Statistics tab for the IP output ports contains a summary of each port status. There are two
sub-tabs: one for Ethernet 1, and another for Ethernet 2. The tab is depicted below:
Ethernet Port 1 Ethernet Port 2 Ethernet Port 1 Ethernet Port 2 Ethernet Port 1 Ethernet Port 2
The indicators can have the following values:
•
OK: The IP Output is operating normally (either streaming or ready to stream).
•
No Response: The IP Output is configured for unicast operation, but it does not have a
destination MAC address. If there is a connection to this output, Dashboard™ Card State
and the Status LED will be red.
•
No Response: The IP Output is configured for unicast operation, and the destination
stopped responding to ARP. The IP Output is using an old cached MAC address. If
there is a connection to this output, the Dashboard™ Card State will be yellow (but
packets are being transmitted).
•
Disabled: The IP Output has been disabled (by setting Enable to No).
