Hi Oliver,
OK, good to hear that they all use SNMP::Info::Layer2::Catalyst.
Looks like there haven't been many changes to this device class between
release 2.01 and current SNMP::Info so I don't understand yet how it has
changed... but can you try a local modification as a workaround?
Find the Catalyst.pm file (with SNMP/Info/Layer2/ in the path leading to
it) and locate the "sub cisco_comm_indexing {" function; the next line
will read "return 1;" and can be changed to "return 0;". This should
avoid macsucking each VLAN for the SNMP::Info::Layer2::Catalyst device
class.

Yes, it was running very fine all the time.
Let's try something else.
1) What's the "SNMP Class" reported for these switches in your
Netdisco2 install?
SNMP::Info::Layer2::Catalyst
I checked it for all switches.
2) What models are involved, can you share one or two "Description"
examples?

Generally a combination of "layers" capabilities with description
and/or SNMP vendor ID is used to determine the SNMP::Info class. If we
can find some common factor there allowing your "problematic" switches
to be put into a different SNMP::Info class, we can probably find a
class that supports the basic functionality without doing a macsuck
per VLAN.
What would be great.
Thanks a lot.

Hi Oliver,
Going through the list mails, I saw that nobody had replied to your
question yet.
Netdisco 2.0 does macsuck in the same way that Netdisco 1.x does: it
asks the SNMP::Info class whether or not to do the macsuck per VLAN
and then collects all the forwarding table entries.
Can you share with us what version of SNMP::Info is running on the ND1
system and what version is installed on the ND2 system? Maybe we can
find some way to fix this for you.

Problem as described in a post from Drik Troendle some time ago.
*[Netdisco] Netdisco2 Macsuck CPU Utilization on Cisco Catalyst 6500
<http://sourceforge.net/p/netdisco/mailman/message/33520728/>*
From: Troendle, Dirk (SCC) <dirk.troendle@pa...> - 2015-03-02 15:54:47
It takes about 2-3 hours, depending from the device type, to read all
mac address assignment from the switch. The CPU get up to 100 %. With
Netdisco Version 1.0 I had no problems. The MacSuck run took max. 1.5
minutes. Cisco Nexus and IOS and some other vendor did not run into
problems with Version 2.
Netdisco Version1.0 runs MacSuck in a different way as Version 2.0 do,
right ?
Version 2 request mac address assignments per Vlan and Catalyst with
CatOS spend a lot of time (CPU) to send snmp answers. Version 1.0
seems
to get the mac addresses from the bridgetable.
'Saw : 1440 forwarding table entries. Took 82 seconds.'
Any ideas to get that kind of request in Netdisco Version 2 ?

Oliver Buehrig
