Here's the procedure to backup a config file for an SGE2010 switch to a TFTP Server using SNMP.
1) Download the MIB files we officially released from cisco.com
http://www.cisco.com/cisco/software/release.html?mdfid=282414069&flowid=3650&softwareid=283415684&release=3.0.0&relind=AVAILABLE&rellifecycle=&reltype=latest
2) Compile the MIB files on MIB browser e.g. MG-SOFT, SilverCreek. Make sure there is no compilation errors.
3) Configure SNMPv2 or SNMPv3 accordingly on SGE2010 switch
4) Look for CISCOSBCopy.mib file.
The OID is SNMPv2-SMI::enterprises(1.3.6.1.4.1).cisco(9).otherEnterpise(6).ciscosb(1).odm1(101).CISCOSBCopy(87)
Using rlCopyTable(2), create an new entry on this particular table:
a. rlCopyRowStatus: 4 (createAndgo)
b. rlCopySourceLocation: 1 (local)
c. rlCopySourceIpAddress: 0.0.0.0
d. rlCopySourceUnitNumber: 1
e. rlCopySourceFileName: (blank)
f. rlCopySourceFileType: 3 (startup config), 2 is for running config
g. rlCopyDestinationLocation: 3 (tftp)
h. rlCopyDestinationIpAddress: 192.168.10.22 (tftp server ip)
i. rlCopyDestinationUnitNumber: 1
j. rlCopyDestinationFileName: 0x61:62:63 (in hex, abc)
By doing that, it should able to backup device startup config from device to remove tftp server.
