Hi,

I've configured SNMP v3 correctly on an ERS4900 series switch, all is working fine. I'm able to send traps v3 too. But I would test to send Informs instead of Traps: so I've configured this with this command:

snmp-server host v3 inform

and nothing is sent by the switch. What I'm doing wrong ?

Thanks for any advice.

This is the script that I have always used with no issues -

no password security
snmp-server enable
snmp-server user <Username1> sha <Authentication Key> aes <Privacy Key> read-view nncli notify-view nncli
snmp-server user <Username2> sha <Authentication Key> aes <Privacy Key> read-view nncli

default snmp-server host
snmp-server host <Trap Receiver IP> v3 authPriv <Username1>

no snmp-server community

no password security isn’t required, but if you do have password security turned on then you can't script it out in one line and will have to confirm the Keys as you enter them.

Jean,

I'm having the same issue with a ERS 5900. Did you ever figure it out?

Hi,

I've already seen the doc about SNMP trap/inform notifications. I was wrong in my last message: the right command that I use is this one:

snmp-server host A.B.C.D v3 auth-priv inform

but as I mentionned, nothing is sent by the switch.

From the manual, SNMP inform configuration is as below.

Only different thing with Trap is "Generates acknowledge Inform requests"

snmp-server host {A.B.C.D | } [port <1-165535>] v3 {auth | no-auth | auth-priv} [filter ] [inform] [retries <0-255>] [timeout <1-2147483647>]
