Indicates the IP address of the SNMP printer. The field on the tab is "TCP/IP address". 3. Check this actual destination attribute: snmp-active Indicates whether the server has been able to establish an SNMP session with the printer. The field on the SNMP tab is "SNMP is active". 4. Set these server attributes: v snmp-discovery-during-startup Indicates whether the server queries the printer MIB when InfoPrint Manager starts or whether the server gets the printer status when it periodically polls the printer. The default is "true", but you might want to set it to "false" if you have several SNMP printers and you want to make the server start faster. The field on the SNMP tab is "Discover printers at startup". v snmp-normal-poll-interval Indicates the number of seconds that the server should wait after sequentially polling all the SNMP printers without known problems. Increasing the polling interval causes the server to use less CPU and network resources for SNMP polling, but it makes the currently shown printer status (for printers that are not currently printing) less accurate. The field on the SNMP tab is "Normal poll interval". v snmp-problem-poll-interval Indicates the number of seconds that the server should wait after sequentially polling all the SNMP printers with known problems. Increasing the polling interval causes the server to use less CPU and network resources for SNMP polling, but it makes the currently shown printer status (for printers that are not currently printing) less accurate. The field on the SNMP tab is "Problem poll interval". For more information about the SNMP actual destination attributes, see the "InfoPrint Object attributes" chapter in the InfoPrint Manager: Reference. Effects on performance with SNMP The performance areas that SNMP can influence are: v Server start-up v Actual destination queries v SNMP polling v Number of SNMP printers on a server Server start-up If you set snmp-discovery-during-startup to "true", the server start-up might be slow because the server queries the printer MIB for each SNMP enabled actual destination for the most current information. Setting this attribute to "false" can improve startup performance. However, the initial actual destination status is not current and won't be until because the server polls the printer next. Actual destination queries On an SNMP printer, when you query an actual destination attribute that might be affected by the printer MIB (for example, destination-state), the default is that the server uses SNMP at the same time to get the relevant information from the Chapter 13.
