Disabling The Snmp Agent; Configuring Community Strings - Cisco WS-C3560-48PS-S Software Configuration Manual

Configuring SNMP

Disabling the SNMP Agent

Beginning in privileged EXEC mode, follow these steps to disable the SNMP agent:
Command
Step 1
configure terminal
Step 2
no snmp-server
Step 3
end
Step 4 show running-config
Step 5
copy running-config startup-config
The no snmp-server global configuration command disables all running versions (version 1, version 2C,
and version 3) on the device. No specific IOS command exists to enable SNMP. The first snmp-server
global configuration command that you enter enables all versions of SNMP.
