Hello list,

It has been some time since I was administering Spectrum every day. I am
involved in one project where we would like to use Spectrum in order to
get MAC addresses of end devices connected to Cisco switch ports.
Required information is located in dot1dTpFdbTable in MIB, but content
of the table has to be queried by SNMP community string indexed with
VLAN the relevant port belongs to. i.e. pub...@120

Is there any way to tell Spectrum to use such SNMP string to poll the
switch and get that values from particular VLAN, while polling the
device for fault management with standard SNMP string?

I remember a statement from development regarding similar topic asked
few years ago - Spectrum is NOT designed and ready to poll a single
device with multiple SNMP strings (except the attribute that stores the
RW SNMP string for special write actions)
Is this still a true? Has anything changed yet?

Thanks a lot for any comments.
Regards,
Ales

Switch VLANs 
Switch Port Trace (SPT) queries the switch CAM table for each VLAN;
therefore, the switch must be an unreserved and operational Ethernet
VLAN for success of the query. SPT queries vtpVlanTable to determine the
VLAN list. 
For each VLAN, SPT searches the CAM table for the MAC address. Since CAM
tables are stored per VLAN, community string indexing is used to query
the switch CAM table. SPT queries dot1dTpFdbTable to get the CAM table
entries. In addition to the switch CAM table, SPT also queries the
following MIB tables (see Figure 10-20
<http://www.cisco.com/en/US/docs/wireless/wcs/6.0/configuration/guide/6_
0ctrlcfg.html> ).

Note  <<Picture (Device Independent Bitmap)>> The switch CAM table must
be accessible using community string indexing (such as pub...@1).
