Viewing Performance and ATM Statistics 195
Viewing Ethernet Card Ethernet statistics are collected according to the Ethernet bridge MIB on the Statistics Ethernet 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 the Ethernet port.
To view Ethernet port statistics, follow these steps:
1From the Card Statistics menu, shown earlier in Figure 146, select [6] ETHERNET.
2Select [1] Port 1.
3Select the option corresponding to the type of statistic you want to view: [1] Ethernet Statistics or [2] ATM Statistics.
Ethernet Statistics
The Ethernet Statistics screen displays the following statistics:
Bridge Statistics
Port 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 on this port.
Forwarded Frames—The number of incoming frames at this port that were forwarded.
Total frames transmitted—The total number of frames transmitted at this port.
Filtering Statistics
MAC MTU Exceeded—The number of frames discarded because of a size greater than the maximum MTU size for the port.
No ATM VCs present—The number of frames discarded because there was no
ATM 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 output port was disabled.
Source address filtered—The number of frames discarded due to source address filtering.
Destination address filtered—The number of frames discarded due to destination address filtering.
SAP Filtered—The number of frames discarded due to the protocol filtering operation.
