 Notification Configurations Step 2 Step 3 Step 4 Step 5 snmp-server host ip udp-port user-name [smode { v1 | v2c | v3 }] [slev {noAuthNoPriv | authNoPriv | authPriv }] [type { trap | inform}] [retries retries] [timeout timeout] Configure parameters of the NMS host and packet handling mechanism. ip: Specify the IP address of the NMS host in IPv4 or IPv6. Make sure the NMS host and the switch can reach each other. udp-port: Specify a UDP port on the NMS host to receive notifications. The default is port 162. For communication security, we recommend that you change the port number under the condition that communications on other UDP ports are not affected. user-name: Enter the name used by the NMS host. When the NMS host uses SNMPv1 or SNMPv2c, enter the Community Name; when the NMS host uses SNMPv3, enter the User Name of the SNMP Group. v1 | v2c | v3: Choose the security model used by the user from the following: SNMPv1, SNMPv2c, SNMPv3. The NMS host should use the corresponding SNMP version. noAuthNoPriv | authNoPriv | authPriv: For SNMPv3 groups, choose a security level from noAuthNoPriv (no authorization and no encryption), authNoPriv (authorization and no encryption), authPriv (authorization and encryption). The default is noAuthNoPriv. Note that if you have chosen v1 or v2c as the security model, the security level cannot be configured. trap | inform: Choose a notification type for the NMS host. For SNMPv1, the supported type is Trap. For SNMPv2c and SNMPv3, you can configure the type as Trap or Inform. Trap: The switch will send Trap messages to the NMS host when certain events occur. When the NMS host receives a Trap message, it will not send a response to the switch. Thus the switch cannot tell whether a message is received or not, and the messages that are not received will not be resent. Inform: The switch will send Inform messages to the NMS host when certain events occur. When the NMS host receives an Inform message, it sends a response to the switch. If the switch does not receive any response within the timeout interval, it will resend the Inform message. Therefore, Inform is more reliable than Trap. retries: Set the retry times for Inform messages. The range is between 1 to 255 and the default is 3. The switch will resend the Inform message if it does not receive any response from the NMS host within the timeout interval. And it will stop sending Inform message when the retry times reaches the limit. timeout: Set the time that the switch waits for a response. Valid values are from 1 to 3600 seconds; the default is 100 seconds. The switch will resend the Inform message if it does not receive a response from the NMS host within the timeout interval. show snmp-server host Verify the information of the host. end Return to Privileged EXEC Mode. copy running-config startup-config Save the settings in the configuration file.
