what are the ports to open for snmpv3?

Hi,

This is the first time I'm using snmpv3.

I have a firewall.

Understand that normal snmpv1/2 uses TCP and UDP ports 161 and 162.

But snmpv3 also has authentication, usernames etc.

So, may I know what are the ports and protocols that I should open on the firewall besides 161 and 162?

Pls reply quickly.

Tks!

rgds,

rachel

SNMPv3 uses the same ports as SNMPv1/v2c. You need to open 161 for polling, and 162 for notifications (e.g. traps).
