Re: Send trap to subnet

Hi,

I have just taken a look into the link provided in your last mail for man
page of snmpd.conf. It is also having the description for community string
as follows

A restricted source can either be a specific hostname (or address), or a
subnet - represented as IP/MASK (e.g. 10.10.10.0/255.255.255.0), or IP/BITS
(e.g. 10.10.10.0/24), or the IPv6 equivalents.
