1 LAN command This command executes the LAN-specific SDA extension image which is a collection of LAN-specific commands which mirror some of the display functions of SYS$SYSTEM:LANCP.EXE in SDA. By default this image is loaded from SYS$SHARE. However, it can be redirected with the following logical: $ define lan$sda [dir-spec]lan$sda.exe Format: SDA> LAN command 2 HELP This command displays help data for the LAN SDA extension. 2 COUNTERS Displays LAN device counters data.

Format LAN RINGS 3 Parameters None. 3 Qualifiers /DEVICE /DEVICE=(device1,device2,...) Includes specific LAN devices. The default is all LAN devices included. Device names are displayed by the LAN DEVICES command. Each device name may be preceded by "NO" to exclude the device(s). /DEVICE=ALL includes all devices. /DEVICE=NOdevname, equivalent to /DEVICE=(ALL,NOdevname), includes all devices except device devname. /DEVICE=devname, equivalent to /DEVICE=(NOALL,devname) selects only devname.. /VALIDATE /VALIDATE Looks for each VCRP or CXB address in the queues and notes which queue entry(s) they are found in. 3 Example SDA> LAN RINGS/DEVICE=EWA Displays LAN queue information for LAN device EWA. 2 TRACE This command displays the trace data logged for the specified devices. Tracing entries are displayed by default from oldest entries to most recent. It correspondingly creates the following symbols: TRACE - pointer to the trace data for the current device TRCHDR - pointer to the trace header data for the current device 3 Parameters None. 3 Qualifiers /CONTEXT /CONTEXT Displays LAN driver event definition. /DEVICE /DEVICE=(device1,device2,...) Includes specific LAN devices. The default is all LAN devices included. Device names are displayed by the LAN DEVICES command. Each device name may be preceded by "NO" to exclude the device(s). /DEVICE=ALL includes all devices. /DEVICE=NOdevname, equivalent to /DEVICE=(ALL,NOdevname), includes all devices except device devname. /DEVICE=devname, equivalent to /DEVICE=(NOALL,devname) selects only devname.. /EVENT /EVENT=(event1,event2,...) Enables trace display of specific events. The default is all events. Event names are displayed by the LAN TRACE/CONTEXT command. Each event name may be preceded by "NO" to exclude the event. /EVENT=ALL includes all events. /EVENT=(ALL,NOEVENTn) includes all events except EVENTn. /EVENT=EVENTn (equivalent to (NOALL,EVENTn) selects only EVENTn. /REVERSE /REVERSE Displays tracing data from the most recent entries to the oldest. 3 Example SDA> LAN TRACE/DEVICE=EWA Displays LAN trace information for LAN device EWA. 2 VC Displays LAN device VC data for ATM devices. Format LAN VC 3 Parameters None. 3 Qualifiers /DEVICE /DEVICE=(device1,device2,...) Includes specific LAN devices. The default is all LAN devices included. Device names are displayed by the LAN DEVICES command. Each device name may be preceded by "NO" to exclude the device(s). /DEVICE=ALL includes all devices. /DEVICE=NOdevname, equivalent to /DEVICE=(ALL,NOdevname), includes all devices except device devname. /DEVICE=devname, equivalent to /DEVICE=(NOALL,devname) selects only devname.. 3 Example SDA> LAN VC/DEVICE=HWA Displays LAN VC data for LAN device HWA. 2 FCARP Displays Address Resolution Table for FIbre Channel devices.
