===Enable a SNMP server under IOS===

Go into __enable mode__, then __configure mode__:
<code>
GFlop$ enable
GFlop# conf t
</code>

Create an access list to __restrict snmp usage__:
<code>
GFlop(config)# access-list 1 permit 192.168.1.4
</code>

__Enable the snmp server__
<code>
GFlop(config)# snmp-server location Foo Bar
GFlop(config)# snmp-server contact Foo@Bar.net
GFlop(config)# snmp-server community public ro 1
</code>
(Note: You could remplace public with the community you wants, ro with rw for using snmp with write access, and 1 with the right access list you've created.)


====Sample Config====
<code>
access-list 1 permit 192.168.1.4
!
snmp-server community ilovecisco RO 1
snmp-server location Garage ed
!
