Hi Hugo, Many thanks for the reply.
If I can ask another related question. If we treat the switch as a single entity, how could we determine what was causing for example a switch ping latency?

You do not want to see each port. You might want to see each port if you run a tool like cacti to track the amount of traffic but that's it. In a normal network you take a switch as a single entity. Each host will have the switch as parent and the switch will have another parent. If the switch goes down so will all the host attached to it. And if just one or two hosts go down it is either a host, a cable or a switch port issue. The change of an individual port breaking down is not worth the trouble of having an entity set for each port. Even with templates it is quite a resource hog to keep it up-to-date. Some of the smarter switches will not enjoy getting a load of SNMP requests to verify each and every port. And if your switch is not SNMP manageble you will not even be able to get any status at all and this whole discussion is futile anyway. (Building and troubleshooiting network is what I do for a living.) If you monitor each switch port you will be in for surprises if someone plugs over a cable just to verify wether the cable, the host nic or the switch port is broken. Only paranoid type networks might even considere doing a portlevel check on the switch. But those networks have fixed MAC addresses assigned to each port and propably will not allow SNMP anyway. (SNMP being UDP and all. ;-) So in the 'real world' you considere your switch as a single entity and do not bother with the ports. Hugo. -- I hate duplicates. Just reply to the relevant mailinglist.
