Field

Description

 

 

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.
