I recall from the forums that Cisco is somewhat odd, but does this help

New to Zenoss and I am trying to evaluate it. It would be helpful if anyone could answer my question about Zenoss monitoring Cisco devices. Does anyone know if it is possible to monitor Cisco switch ports for up/down status via SNMP and be able to create alerts based on the status? Thanks.
This isn't necessarily Cisco centric, but it may not be a good idea to monitor individual ports via snmp. For example, I don't monitor any individual switch ports as these tend to go up and down all the time. I am, however, interested in ports that are part of a port channel or multi-homed link ports. Zenoss is very powerful in the sense that you can get monitor happy; which equals alerts. Before I monitor anything, I try to decide do I really want to be notified of this event.
you can enable traps in the global configuration mode:
snmp-server enable traps snmp
snmp-server enable traps syslog
it might be worth while to have this command also:
where ip-address is the ip of your zenoss box
These commands take into the assumption that you already have snmp enabled on your cisco and that zenoss is currently monitoring it
