Using Syslog Messaging to Monitor Router
114088 Rev. A C-39
Parameter: Log Evt Lower Bound
Attribute Name: wfSyslogEntFltrLogEvtLowBnd
Attribute Number: 7
Default: 0
Range: 0 to 255
Function: Along with the Log Evt Upper Bound, this parameter/attribute specifies
an event number (code) or range of event numbers. The number(s)
correspond to event messages you want to forward to the remote host
associated with this filter.
For a complete list of event codes for each entity, refer to Event Messages
for Routers and BNX Platforms for this version of the router software.
Instructions: To specify a range of event numbers that identify messages you want to
forward to a remote host, set the value of this parameter/attribute to the
low number of the range. Set the value of the
wfSyslogEntFltrLogEvtUppBnd (Log Event Upper Bound) parameter to
the high number of the range.
Any range you specify includes the values for the lower and upper bound
parameters/attributes. For example, if you specify a lower bound of 2 and
an upper bound of 7, Syslog forwards all messages with event codes of 2
through 7 (inclusive), logged by the entity defined under
wfSyslogEntFltrNum (Filter Entity Name). Syslog ignores all other event
messages.
To filter (select only) a specific event, set the value of
wfSyslogEntFltrLogEvtLowBnd to the code number for that event. Set
the value of wfSyslogEntFltrLogEvtUppBnd (Log Evt Upper Bound) to
the same code number. For example, to forward only log messages that
have an event code of 10, enter 10 as the value of
wfSyslogEntFltrLogEvtLowBnd and as the value of the
wfSyslogEntFltrLogEvtUppBnd (Log Evt Upper Bound).
If you do not want to filter by event code, accept the lower and upper
bound default values of 0 to 255. In this case, Syslog checks for filtering
criteria based on a message severity mask (wfSyslogEntFltrSevMask). If
you specify lower and upper boundary values of 255 (the wildcard entity
number), Syslog ignores this attribute as filtering criterion.

set wfSyslogEntFltrEntry.wfSyslogEntFltrLogEvtLowBnd.
