lltdump - Low Latency Transport (LLT) Protocol dump utility
lltdump -f network_device [-A] [-c cluster] [-C] [-p sap | -S] [-P] [-R] [-t linktype] [-v] [-V]
lltdump -f network_device [-D] [-p sap | -S] [-P] [-t linktype]
The lltdump utility displays the LLT traffic being received by a system on a particular network interface. It accomplishes this by opening a stream, binding to the LLT SAP, reading a copy of network packets as they are received, then interpreting and displaying them as LLT packets. This option should be used only on private network interfaces using LLT because other protocol traffic can cause erroneous output.
-A Suppress the printing of ACK packets, which are data ACKs that may be used as heartbeats and that can clutter the output. -c cluster Set the cluster number to monitor. This option is useful with the -P option to filter out packets destined for systems in another cluster. -C Suppress the printing of CONN_REQ packets, which may be abundant and may clutter the output. -D Print a list of unique clusterid-nodeid-version tuples present on the network. -f network_device Specify the name of the network device to monitor. The device name and unit number may be separated by a colon for DLPI style-2 devices (for example, /dev/net0, /dev/hme:1). - h Display the usage message. -p sap Set the sap to monitor. On some platforms, the same sap cannot be bound more than once. In that case one can use the -S option. -P Set the interface to promiscuous mode (MAC_address) to see traffic destined for other systems, as well as traffic destined for the local system. -R Suppress the printing of AAK packets, which are address resolution ACKs that may be used as broadcast heartbeats and that can clutter the output. -S Set the stream to promiscuous SAP mode. This is available only on platforms that support it. It is useful if the network device does not allow more than one stream to bind to the same SAP. If the network is used for traffic other than LLT, the output is undefined because other packets are interpreted as LLT. -t linktype Specify the link type. Curently, only link type "ether" is supported. -v Enable verbose output. This option shows the first 12 octets of packet data. -V Enable verbose output. This option shows all packet data.
