Displaying Information About the Access Server
17-14 Managing the Access Server
Receive Failure Reasons Mask providing information about the type or
types of receive failure encountered if the
Receive Failures counter is not zero. This is a
cumulative mask. The following are the bits
defined in the mask:
Bit
0
1
2
Unrecognized Destination Number of times a frame was passed through
the hardware, but the access server did not
recognize the multicast address and discarded
the message. This value reflects multicast
traffic or other traffic addressed to the access
server from protocols not supported by the
access server. The count will be high if the
access server does not have an IP address and
is connected to a network with ARP traffic. If
this count is extremely high (greater than 10
for each second of uptime), the access server
performance could be adversely effected.
Data Overrun Number of times the access server hardware
lost an incoming frame, because it was unable
to keep up with the data rate. This value should
be 0.
User Buffer Unavailable Number of times the access server did not have
a user buffer available to store an incoming
frame that passed through the system buffer.
This counter should accumulate at a rate of less
than two counts per day. Note that the value
of this counter could be high if there are a large
number of LAT service multicast
announcements on the network. Also, it is
normal to experience some errors when nodes
are added to the Ethernet.
