RIDGE TATISTICS
The system collects bridge statistics for each LAN port and for WAN connections. These bridge
statistics include information on the number of frames received, forwarded, discarded or
transmitted. If the system is configured for two LAN ports, there is a line of counters for each LAN
port. However, the WAN counters are totaled for all WAN ports.
Display bridge statistics by issuing the br stats command at the administration console:
Received
Number of frames received from a LAN port or WAN connection.
Forwarded
Number of frames received from LAN port 1 or LAN port 2 or all WAN ports and processed for
transmission to the proper networks. Discarded frames are not forwarded for transmission.
Discarded
Number frames received and then discarded (i.e., not forwarded to another LAN port or WAN
connection).
Transmit
Number of frames sent out through LAN port 1 or LAN port 2 or all WAN ports to connected
networks.
Note: Forward refers to the passing of a received frame from one port to another within the
SmartSwitch Remote Access Module. A frame can be received on any port (LAN or WAN)
and forwarded to any other port, unless it is discarded. A forwarded frame is one which is
not deliberately discarded (for example, via filters) by the SmartSwitch Remote Access
Module. Once the frame gets to the new port, it is usually transmitted. However, it may not
be transmitted, such as when a packet is forwarded to a WAN port, but no connection is
up on that port.
C S
OMPRESSION TATISTICS
The system collects the following compression statistics for each active compression connection.
These statistics can be displayed by issuing the cmp stats or the cmp stats <device name>
command at the administration console. The cmp stats command will display the compression
statistics for all active connections. The cmp stats <device name> command will display the
compression statistics for the specified device. Note that the device name is case sensitive.
Note: When using PPP, it is possible that CCP can open with no agreed upon compression
algorithm in one or both directions. In such cases, the connection is considered to be
running with compression, and will consequently be picked up by the CMP command.
However, the ratios and counters for the direction(s) without an actual compression
algorithm negotiated will not indicate any effective compression or decompression.
