This trace includes SNMP records for the stations associated with 4 access points at a three-day computer-science conference.

This trace contains 12 trace files. Those files are 
named Stations_%AP_Name%_%Day%.out -- where %AP_Name% 
can be one of NE, NW, SE, or SW; and %Day% can be Wed, Thu, 
or Fri. Thus the trace file for the NE AP on Wednesday, 
is Stations_NE_Wed.out. The SNMP OID used to generate these 
trace files was .1.3.6.1.4.1, which corresponds to the MIB 
entry for "Associated Stations" and gives the MAC address, 
average received SNR, total transmitted bytes, and total 
transmitted packets for each mobile station associated to 
the AP. 
Each poll entry begins with a timestamp and entries from 
successive polls are separated by the line "End of MIB subtree".

The trace-collection routine polled the APs at one minute intervals.

The snmputil tool is a command-line utility that uses the standard Win32 SNMP Management API.

SNMP files whose format is the same as those of 
				ucsd/sigcomm2001/snmp/Stations and ucsd/sigcomm2001/snmp/AP_Mibtree.

option[get|getnext|walk] node_address password snmp_oid

The usage for snmputil is: 
snmputil option[get|getnext|walk] node_address password snmp_oid
For example, to walk the entire MIB tree at the AP, the usage is: 
snmputil walk AP_IP_address password .1.3.6.1.2.1

The snmputil tool is a command-line utility that uses the standard 
Win32 SNMP Management API. The source-code consists of one 
source file (snmputil.c) and a makefile. If you are building 
snmputil.exe on your own, make sure that you have the Windows SNMP 
libraries, snmpapi.lib and mgmtapi.lib.

This tool generates the data matching the pattern given by the users.

SNMP trace obtained by snmputil

data matching the pattern given by the users

The extract.pl script can be used to parse all SNMP output files 
in the trace to look for a certain pattern. The pattern may be 
a phrase representing all or part of an SNMP OID, or simply text 
that appears in the trace file. The script has detailed comments 
on how to use it. Since we collected the SNMP data using snmputil, 
the scripts are written specifically to parse that output. 
The traces contain the SNMP data collected at one-minute intervals, 
and extract.pl uses these timestamps in the trace file to parse 
the data. Since each SNMP OID has a unique entry in the trace, 
extract.pl can be used to extract the values of all the SNMP 
variables over the entire duration of the trace.
