Solved: SNMP v3 - Error in Authentication password

misd.network.support · ‎07-15-2008

Hi,

Im trying to configure snmp v3 on a 2960 switch (IOS 12.2(44)SE. I use the following commands:

snmp-server group mygroup v3 priv

snmp-server user myuser mygroup v3 encrypted auth sha myauthpass priv aes 128 myprivpass

I then get the error message:

%Error in Authentication password

Any ideas?

Cheers,

Ben

When you specify the "encrypted" keyword, you need to specify the password in an encrypted string. It doesn't look like you want this. Try:

snmp-server user myuser mygroup v3 auth sha myauthpass priv aes 128 myprivpass

Looks like you need to specify a read or write view

Syntax for the group name :

snmp-server group [groupname {v1 | v2c | v3{auth | noauth | priv}}]

[read readview] [write writeview] [notify notifyview] [access

access-list]

snmp-server user username [groupname remote ip-address [udp-port port]

{v1 | v2c | v3 [encrypted] [auth {md5 | sha} auth-password [priv des56

priv password]] [access access-list]

Thanks for the reply.

As I understand the syntax in [] is optional. I tried specifying a readonly view by changing my group command to:

snmp-server group mygroup v3 priv read readonly

I still get the same error message. Interestingly if I drop the optional "encrypted" keyword from the snmp-server user command, it does indeed create the user. The user doesn't appear in the config - but a show snmp user does list it.

Cheers,
