1570.0. "SNMP on 900EF" by STROP::LAYLAND (The good die young, the wealthy stay healthy.) Thu Oct 13 1994 12:29

I have been asked to set up a demonstration of Hubwatch
and Netview. The purpose is to see link and wan failure
on Brouters/WAN90 and the bridge900EF(MX).  It would be
helpfull if someone has a similar configuration and could 
answer some of the following:-

What interface information can I obtain from the bridge 
FDDI port, (900EF), WAN90, Brouter 90. Since the WAN90
and brouter can be asigned a numbered (IP) link, then
an SNMP get from the iftable should indicate a link down,
but I am not sure what to expect from the bridge. 

Regards John Layland, partners support UK.

ps note entered in the netview and wan90 notes.

1570.3...and WANrouter and DECbrouter 90's, too.SLINK::HOODI'd rather be at the PenobscotFri Oct 14 1994 10:2444
Hmmm,  I only gave the bridge/switch info in .1

HUBwatch does not support the WANrouter 90's (other than front panel).
They support only MIB-II GET's.


For the DECbrouter 90's, the following are used by HUBwatch:

Module info:
   sysName           snmpInPkts                   snmpInTooBigs
   sysLocation       snmpOutPkts                  snmpInNoSuchNames
   sysContact        snmpInGetRequests            snmpInBadValues
   sysDescr          snmpInGetNexts               snmpInReadOnlys
   sysUpTime         snmpInSetRequests            snmpInGenErrs
   ifNumber          snmpOutTraps                 snmpOutTooBigs
   bufferElFree      snmpInBadVersions            snmpOutNoSuchNames
   bufferElMiss      snmpInBadCommunityNames      snmpOutBadValues
   bufferElHit       snmpInBadCommunityUses       snmpOutReadOnlys
   freeMem           snmpInASNParseErrors         snmpOutGenErrs
   avgBusy5          snmpInBadTypes

Port info:
   ifOperStatus      locIfInPktsSec
   ifAdminStatus     locIfOutPktsSec
   ifDescr           ifPhysAddress   [Ethernet port only]
   locIfDescr        ifInErrors
   ifType            ifOutErrors

   For the following protocols, in and out packets, and
   in and out octets per port:
      Apollo         MOP
      Appletalk      Novell
      ARP            PUP
      bridge         stp (bridging)
      chaosnet       srb
      CLNS           stun
      DECnet         vines
      IP             xns

For the DECbrouters, if a variable isn't MIB-II, it's from the Cisco
MIB extensions.

1570.4MIB variables for polling bridge portsNETCAD::SLAWRENCEMon Oct 17 1994 10:218
    
    All the 900 series switches support MIB-II and the IETF Bridge MIB (rfc
    1493).  You can poll ifOperStatus - another one to look at is
    dot1dStpPortState, which will tell you the state of the spanning tree
    on each port.  
    
    For the FDDI port, I also poll fddimibPORTConnectState.
