External SNMP polls are packaged in poll libraries, which can be downloaded from the ARRIS Digital CM site.
Because they are external to SDM software and device firmware releases, External SNMP polls can be loaded onto the SDM at any time, using the SDM's user interface. It is not necessary to install a software release to get them. Each poll library contains one or more poll definitions, with revisions. When a poll is loaded, all instances of that poll are updated to that definition. The SDM accepts only the highest loaded version of a poll definition.
Poll definitions packaged in a poll library contain SNMP MIB parameters that are to be polled from a specific device. Once a poll has been loaded, it is associated with a device instance. External SNMP polls can then be used and managed in the same manner as any other performance poll.
