Operations Guide ­ DOC. 7036A 24-Port Managed PoE Switch: CEN-SWPOE-24 · 17 24-Port Managed PoE Switch Crestron CEN-SWPOE-24 SNMP Simple Network Management Protocol (SNMP) is a communication protocol designed specifically for managing devices on a network. SNMP is used to configure devices for proper operation in a network environment, as well as to monitor them to evaluate performance or detect potential problems. Traps indicating status changes are issued by the switch to specified trap managers. You must specify trap managers so that key events are reported by this switch to your management station. You can specify up to five management stations that will receive authentication failure messages and other notification messages from the switch. To configure SNMP, select either of the following from the drop-down list: · · Disabled: Prevents the switch from being administered remotely via SNMP. Enabled: (Default setting) Allows the switch to be administered remotely via SNMP. Assign read-only or read-write privileges to the SNMP manager (applicable only if SNMP is enabled): · Read-only community: In the text box, enter a text string that functions as a password to allow the SNMP manager to read configuration settings from the switch. The read-only community text string appears as solid black circles. Read-write community: In the text box, enter a text string that functions as a password to allow the SNMP manager to read configuration settings from and write configuration settings to the switch. The read-write community text string appears as solid black circles. · Add entries to the SNMP Trap Table to send notification events from the switch to SNMP managers when a significant event occurs: 1. Syslog Remote Logging Click the checkbox to activate trap notification. In the IP Address column, enter the IP address of the device to which the switch is to send traps.
