RouterOS The Dude
1

Hello to all

I have Cisco switch for testing 2960-24TT-L ios 15, latest. I also have MT CCR1009-7G-1C-1S+ router with Dude 6.38.
I like to know is it someone configure cisco device to work in dude over snmp v3 priv ??? I setup cisco but i cann’t see anything in SNMP tab in dude. I use sha auth and des priv in cisco and in snmp profile in dude. Also try with md5 auth and des priv… And any of this combination also, but no luck.

All work fine in v2c and community, but not in any case in v3.

Thank you

Someone ??? Snmp v3 usage on other devices exapt MT ? ex Cisco, D-Link…

Still can’t make it work over v3…

I use snmp with cisco (sg serie) but without security… because only in local networks.
Maybe you can try without security to be sure in first time

5

I try with v3 no auth and it work… in any case, snmp v3 auth or priv woudn’t work.

I’m trying to get probe from APC UPS with SNMPv3 without any luck… Works only without any auth, if any security option selected it fails.
Also tried to connect to Cisco devices, same story.
Bad news, guys.

It looks like Dude is using AES256 or at least not standard AES128

On Cisco routers, it works :

  • if you use just auth and no priv
  • if you use auth and AES256 priv
    It says that the packet is badly crypted if you set it for priv with AES128.


    I don’t know exactly what the moving pieces are.
    On OneAccess routers configured as AES128, it works as long as the packets are small enough.
    As soon as the packet get over some size, it’s considered badly crypted.
    And AES256 is buggy on OneAccess, so…

BTW, AES256, is not supported on standard linux snmpwalk, so we’re king of stuck here.

I filed a support request today.
We’ll see if these tests help us go any further.

Cheers
