Node discovery with SNMPv3 on Cisco 3850
« on: March 10, 2020, 11:29:06 AM »
Hello,

I have a couple 3850 (~40 devices running in 8 stacks) - using NeDi 1.8 they are discovered fine, but I get a status line like:

10.x.x.x     frasw-closet-0E IlIx i362  j1   p1 b0 m24   Ac a4/0o0/0    f0   37/1-28s

.. so no "v#" or "FpXXX" status like I get them from other Cisco devices (older 65xx catalysts, and Nexus 7k/5k) when NeDi discovers nodes per vlan (and yes, there are vlans configured)

I wonder if somebody had success in discovering nodes attached to 3850's using SNMP v3 ?
Any hint welcome..

Best Regards,
Andreas


the v3 config used on the switches is very similar to our other v3 setups:

snmp-server view readview internet included
snmp-server group readonly v3 priv read readview
snmp-server user nedi-md5-aes readonly v3 auth md5 xxxxxxxxx priv aes 128 zzzzzzzzzz
snmp-server group readonly v3 priv context vlan- match prefix read readview


also tried to give context access by vlan id, but that made no change:
snmp-server group readonly v3 priv context vlan-20 read readview

Devices are WS-C3850-48P-S, sysobjid 1.3.6.1.4.1.9.1.1745
