Viewing Performance and ATM Statistics 195Viewing Ethernet CardStatisticsEthernet statistics are collected according to the Ethernet bridge MIB on theEthernet port and on every ATM connection tied to this port. You can view bridge,filtering, and Ethernet statistics, and you can also view ATM VC statistics for theEthernet port.To view Ethernet port statistics, follow these steps:1 From the Card Statistics menu, shown earlier in Figure 146, select [6] ETHERNET.2 Select [1] Port 1.3 Select the option corresponding to the type of statistic you want to view:[1] Ethernet Statistics or [2] ATM Statistics.Ethernet StatisticsThe Ethernet Statistics screen displays the following statistics:Bridge StatisticsPort state—The state of the Ethernet port: connected or not connected.Total frames received—The total number of frames received at this port.Broadcast Frames—The number of broadcast frames received on the port.Discarded Frames—The number of valid frames received that were discarded(filtered) by the forwarding process.Flooded Frames—The total number of incoming frames that were flooded onthis port.Forwarded Frames—The number of incoming frames at this port that wereforwarded.Total frames transmitted—The total number of frames transmitted at this port.Filtering StatisticsMAC MTU Exceeded—The number of frames discarded because of a size greaterthan the maximum MTU size for the port.No ATM VCs present—The number of frames discarded because there was noATM VC associated with the physical port.Bridge discards—The number of frames discarded due to the bridging operation.Output port disabled—The number of frames discarded because the outputport was disabled.Source address filtered—The number of frames discarded due to source addressfiltering.Destination address filtered—The number of frames discarded due todestination address filtering.SAP Filtered—The number of frames discarded due to the protocol filteringoperation.
