is it possible to sniff spantree traffic on a 1900 switch

I am trying to look at bridging traffic on the monitor port of a cat..1900

but the unicast floofing and multicast flooding are disabled by default on the monitoring port. This is preventing the sniffer from capturing these packets. I tried to enadle this feature but was unable to do so.

How do I solution this. code ver...

It shouldn't keep the sniffer from seeing unicast/multicast from the monitor port, it just prevents it from being "flooded" out of this port. You should still be able to see all traffic on the switch. As far as enabling those features I don't think that it is ever supported on the 1900.
