smtring(1M)smtring(1M)NAMEsmtring - examines the state of FDDI ring
SYNOPSIS
/usr/etc/smtring [-pdn] [-i interval] [-t timeout] [-I interface] [host]
DESCRIPTIONsmtring is a tool to examine the state of an FDDI ring. The default is
to report once either when smtring is interrupted or when it terminates
after a 60-second timeout.
The options are:
-d Increase the debug level. Multiple ``d''s increase the level up to
a maximum of five.
-p Passive NIF collection. With this option, smtring ``passively''
collects the NIF frames on the FDDI ring. Without this option, by
default, smtring collects NIF frames ``actively'' by issuing
broadcast NIF_REQUEST frames to elicit an NIF_RESPONSE frame from
FDDI stations and concentrators.
-n Numeric output only. Does not try to translate the MAC address into
its symbolic name in the ethers database.
-i interval
Continually report FDDI neighbor information every interval seconds.
-I interface
Examine the state of an FDDI ring in which interface is inserted.
The interface is a string of the form ``name unit'', for example,
``ipg0''. The default is set to the station's primary interface.
-t timeout
Change the default timeout from 60 seconds to timeout seconds.
host The host can be a FDDI station's MAC address or the symbolic name of
a FDDI station's MAC address which can be found in /etc/ethers or
the NIS ethers.byname map. The ring status data will be collected
by host . The default is set to ``localhost''.
