I’ve been often asked how do you configure SNMP across the variety of network equipment and thought to include a listing here with the use of Variables to define the various inputs that go into an SNMP configuration for the various versions.

Variable Definitions

 ${Read Community String} = SNMP Read-Only
 ${Write Community String} = SNMP Read-Write
 ${NMS IP Address} = IP address of Network Management Server
 ${SNMP Version(v1 | v2c)} = SNMP version Only two choices, v1 and v2c
 ${ACL} = Access-list only allowing SNMP traffic from specificed sources
 ${AuthPasswd} = Password for Integrity
 ${PrivPasswd} = Password for Privacy
 ${User} = SNMPv3 user
 ${Group} = SNMPv3 group

SNMPv1/2c

PROCURVE

 snmp-server enable
 snmp-server community ${Read Community String} operator restricted
 snmp-server community ${Write Community String} manager unrestricted
 snmp-server trap-source
 snmp-server host ${NMS IP Address} community ${Write Community String} trap-level all

CISCO

 snmp-server community ${Read Community String} ro ${ACL}
 snmp-server community ${Write Community String} rw ${ACL}
 snmp-server enable traps
 snmp-server source-interface traps ${Interface}

COMWARE
