Custom ContextEngineId and ContextName
++++++++++++++++++++++++++++++++++++++
Send SNMP SET request using the following options:
* with SNMPv3 with user 'usr-md5-none', MD5 auth and no privacy protocols
* over IPv4/UDP
* to an Agent at demo.snmplabs.com:161
* addressing particular set of Managed Objects at remote SNMP Engine by:
* contextEngineId 0x80004fb805636c6f75644dab22cc and
* contextName 'a172334d7d97871b72241397f713fa12'
* setting SNMPv2-MIB::sysName.0 to new value (type taken from MIB)
Functionally similar to:
| $ snmpset -v3 -u usr-md5-des -l authPriv -A authkey1 -X privkey1 \
| -E 80004fb805636c6f75644dab22cc -n a172334d7d97871b72241397f713fa12 \
| demo.snmplabs.com \
