Save router configuration to tftp server:

#Set copy method via OID ccCopyProtocol:
snmpset -v 2c -c  {community-string} {device-ip-address} 1.3.6.1.4.1.9.9.96.1.1.1.1.2.112 i 1
#Set source filetype to running-config via OID ccCopySourceFileType:
snmpset -v 2c -c  {community-string} {device-ip-address} 1.3.6.1.4.1.9.9.96.1.1.1.1.3.112 i 4
#Set destination to networkfile via OID ccCopyDestFileType:
snmpset -v 2c -c  {community-string} {device-ip-address} 1.3.6.1.4.1.9.9.96.1.1.1.1.4.112 i 1
#Set TFTP server ip via OID ccCopyServerAddress:
snmpset -v 2c -c  {community-string} {device-ip-address} 1.3.6.1.4.1.9.9.96.1.1.1.1.5.112 a {ip-address-tftp-server}
#Set destination filename via OID ccCopyFileName:
snmpset -v 2c -c  {community-string} {device-ip-address} 1.3.6.1.4.1.9.9.96.1.1.1.1.6.112 s router.cfg
#Start tftp download via OID ccCopyEntryRowStatus:
snmpset -v 2c -c  {community-string} {device-ip-address} 1.3.6.1.4.1.9.9.96.1.1.1.1.14.112 i 1

Upload router configuration from tftp server:

#Set copy method:
snmpset -v 2c -c {community-string} {device-ip-address} 1.3.6.1.4.1.9.9.96.1.1.1.1.2.116 i 1
#Set sourcefile to network file:
snmpset -v 2c -c {community-string} {device-ip-address} 1.3.6.1.4.1.9.9.96.1.1.1.1.3.116 i 1
#Set destination to running-config:
snmpset -v 2c -c {community-string} {device-ip-address} 1.3.6.1.4.1.9.9.96.1.1.1.1.4.116 i 4
#Set TFTP server ip:
snmpset -v 2c -c {community-string} {device-ip-address} 1.3.6.1.4.1.9.9.96.1.1.1.1.5.116 a {ip-address-tftp-server}
#Set desination filename:
snmpset -v 2c -c {community-string} {device-ip-address} 1.3.6.1.4.1.9.9.96.1.1.1.1.6.116 s output.cfg
#Start tftp upload via via OID ccCopyEntryRowStatus:
snmpset -v 2c -c {community-string} {device-ip-address} 1.3.6.1.4.1.9.9.96.1.1.1.1.14.116 i 1

Note: The integer highlighted in red is a random integer and you can choose any integer between 1 and 255. Keep in mind to use the same integer for the whole download procedure! See the integer as a session.

This guide describe how to install and configure SNMP on Ubuntu.

1.Installation

root@netflow:/# sudo apt-get install snmpd

2. Configuration
Move existing /etc/snmp/snmpd.conf configuration file to /etc/snmp/snmpd.conf.org

root@netflow:/# mv /etc/snmp/snmpd.conf /etc/snmp/snmpd.conf.org

Create a new /etc/snmp/snmpd.conf file:

# Configure Read-Only community and restrict who can connect
rocommunity COPUBLIC 103.12.179.0/24
rocommunity COPUBLIC 127.0.0.1

# Information about this host
sysLocation bdHUB Dhaka Bangladesh
sysContact noc@bdhub.com

# Which OSI layers are active in this host
# (Application + End-to-End layers)
sysServices 72

Make snmpd use the newly created file and make it listen to all interfaces:

Edit /etc/default/snmpd

root@netflow:/# vi /etc/default/snmpd

Change from:

# snmpd options (use syslog, close stdin/out/err).
SNMPDOPTS=’-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid 127.0.0.1’

To:

# snmpd options (use syslog, close stdin/out/err).
#SNMPDOPTS=’-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid 127.0.0.1’
SNMPDOPTS=’-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid -c /etc/snmp/snmpd.conf’

and restart snmpd

root@netflow:/# /etc/init.d/snmpd restart

3. Test
Check SNMP is running

root@netflow:/# sudo netstat -ulnp | grep 161
udp 0 0 0.0.0.0:161 0.0.0.0:* 28676/snmpd

Check the snmpstatus output

root@netflow:/# snmpstatus -c ‘COPUBLIC’ -v2c 103.12.179.12
