Hi Muris
A couple of things I can think of. First, for Cisco there is a setting to
control whether the stack is discovered as individual items or one:
https://github.com/netdisco/netdisco/wiki/Vendor-Tips#report-cisco-as-single-device-instead-of-stacked-37xx29xxetc
I wonder if there is the same for H3C. Second, this setting is the one
which is aborting your discovery:
https://github.com/netdisco/netdisco/wiki/Configuration#snmp_field_protection
You can change it to force the job to continue, although lack of Serial is
a bit weird and I would want to dig further.
(for example change to '!group:__ANY__' to suppress the function)
Hope that helps,
Oliver.

I have an issue where Cisco 1100 series routers are not reporting connected
mac's/ip addresses on ports, Eg the C1113 version.
I noticed in the debug for macsuck, it says Vlan 1 and 10 are not in use by any
port skipping, but they are actually in use and configured on the port.. so
something doesnt seem right.
Maybe someone else has the same issue? As a comparison ive compared the C1113
and C897 routers (the previous models) where it works.
