Aruba 2530 - Supported Notifications; General Steps for Configuring SNMP Notifications; Snmpv1 and Snmpv2 C Traps

Supported Notifications
By default, the following notifications are enabled on a switch:
• Manager password changes
• SNMP authentication failure
• Link-change traps: when the link on a port changes from up to down (linkDown) or down to up (linkUp)
• Port-security (web, MAC, or 802.1X) authentication failure
• Invalid password entered in a login attempt through a direct serial, Telnet, or SSH connection
• Inability to establish a connection with the RADIUS or TACACS+ authentication server
• DHCP snooping events
• ARP protection events
General steps for configuring SNMP notifications
Procedure
1. Determine the versions of SNMP notifications that you want to use in your network.
If you want to use SNMPv1 and SNMPv2c traps, you must also configure a trap receiver. See the following
sections and follow the required configuration procedures:
• SNMPv1 and SNMPv2c Traps on page 155
• Configuring an SNMP trap receiver (CLI) on page 156
• Enabling SNMPv2c informs (CLI) on page 157
If you want to use SNMPv3 notifications (including traps), you must also configure an SNMPv3 management
station. Follow the required configuration procedure in Configuring SNMPv3 notifications (CLI) on page
158.
2. To reconfigure any of the SNMP notifications that are enabled by default to be sent to a management station
(trap receiver), see Enabling Link-Change Traps (CLI) on page 163.
3. (Optional) See the following sections to configure optional SNMP notification features and verify the current
configuration:
• Configuring the source IP address for SNMP notifications (CLI) on page 164
• Viewing SNMP notification configuration (CLI) on page 166
SNMPv1 and SNMPv2c Traps
The switches support the following functionality from earlier SNMP versions (SNMPv1 and SNMPv2c):
• Trap receivers: A trap receiver is a management station to which the switch sends SNMP traps and
(optionally) event log messages sent from the switch. From the CLI you can configure up to ten SNMP trap
receivers to receive SNMP traps from the switch.
• Default Traps: A switch automatically sends default traps to trap receivers using the configured community
name. You have to configure and supply the community name to use in the trap-receiver config, there is no
