SNMP on Dlink 3100 + Zabbix

[freelsd]

Hi guys. I install zabbix and wanna see traffic on Dlink 3100.
-I create community "mycommunity"
-Dlink option "SNMP Trap Enabled"

Now I have some troubles:
Actual problem:
How I can fast see traffic using ifInOctets ifOutOctets on 20 switches having 50 ports every?


I use template SNMPv2 for my DGS-3100, most items are active. I wanna see traffic on all ports. Can I do it it in standart template SNMPv2?
Dgs supported RFC, what OID(or where OID) for traffic on ports?
Done ifInOctets ifOutOctets - see RFC

#snmpwalk -c mycommunity -v 2c Alex ip_adress
Timeout: No Response from ip_adress
Problem Done - open 161 port

Ty for watching.
