RE: (ASCEND) SNMP questions

Peter,  I've read the responses to your message but don't think they
addressed your question completely.  Available Channels totals are kept in
two places in the Ascend advanced.mib.

This variable (529.4.23.0) is the scalar used to keep track of all the
available channels for the entire device.
    wanAvailableChannels OBJECT-TYPE
        SYNTAX  INTEGER
        ACCESS  read-only
        STATUS  mandatory
        DESCRIPTION
          "The sum of wanLineAvailableChannels for all lines."
       ::= { advancedAgent 23 }

This variable (529.4.21.1.12) is the number available per wan interface.
 wanLineAvailableChannels OBJECT-TYPE
        SYNTAX  INTEGER
        ACCESS  read-only
        STATUS  mandatory
        DESCRIPTION
          "The number of DS0 channels of the line configured as Switched and
	  available for making or accepting calls.
          This variable counts the number of wanLineChannels with the
          wanLineChannelState of bs-idle(7) for all the entries in its
          wanLineChannelEntry table."
       ::= { wanLineEntry 12 }

If your trunk group is all of the wan lines in the entire box then use
wanAvailableChannels.  If your trunk group is a subset of the wan lines then
use wanLineAvailableChannels for each of the member interfaces. Just add the
numbers together. The table is indexed by ifIndex so you should be able to
easily pick what you want.

Subject: (ASCEND) SNMP questions


I've started fooling with MRTG. Inevitably, now I need to know a whole lot
more than I do about SNMP.

Is there an OID equivalent to wanAvailableChannels that returns available
channels by trunk group? I'm thinking wanLineAvailableChannels might be
close, but I'm not sure how to refer to it.

Is there documentation that actually explains what the OIDs actually
return? Ascend's docs list them, but don't explain them?

Finally, how do I do an snmpwalk? Is it a Unix command or a feature of SNMP
managers?

Thanks.
