Try running it locally first:

acl snmpbsu snmp_community snmpsecret
acl admins src 192.168.0.0/24
snmp_port 3401
snmp_access allow snmpbsu localhost
snmp_access allow snmpbsu admins
snmp_access deny all

#/usr/bin/snmpwalk -m /etc/squid/mib.txt -c snmpsecret -v1
localhost:3401 .1.3.6.1.4.1.3495.1

Hope that helps.

Thanking you...
