Out Ucast
(ifOutUcastPkts) The total number of packets transmitted 
by the selected LAN interface that were destined for a 
single address (unicast), expressed as a rate 
(packets/second).
Out NUcast
(ifOutNUcastPkts) The total number of packets 
transmitted by the selected LAN interface that were 
destined for more than one address (either broadcast or 
multicast), expressed as a rate (packets/second).
Out Discards
(ifOutDiscards) The total number of outbound packets 
which were discarded even though no errors were 
detected, expressed as a rate (packets/second); 
well-formed packets are typically discarded in order to 
free up buffer space.
Out Errors
(ifOutErrors) The total number of outbound packets 
which contained errors that prevented them from being 
delivered, expressed as a rate (packets/second).
Viewing Statistics Thresholds
The Hub View provides a way to view trap thresholds that have been set through 
console management for RLP and port health statistics. For each RLP and port 
statistic, you can specify a threshold that, when crossed, causes a trap to be sent to 
a management workstation. A threshold is either a number or a percentage, 
depending on the statistic. The valid range for any number threshold is 0 - 65535 
with the default value being 0. When the measured value for the health statistic 
crosses the threshold (in either direction), a trap is sent to the collecting 
management workstation. (For information on designating workstations to accept 
traps, see Chapter 3, ConÞguring the Trap Table. For deÞnitions of RLP and 
Serial Port Health Statistics, see 
RLP Statistics Thresholds

1.
In the Hub View, click on the appropriate Module Index or Module Name text 
box to display the RLP Menu (see 
). 
2.
Drag down to Thresholds, and release. The RLP Statistics Thresholds
