Snmp Trap Notification Control - Avaya ERS 2500 Technical Configuration Manual

10.10

SNMP Trap Notification Control

SNMP Trap functionality on the ERS 4500 5.4, ERS 2500 4.3, and ERS 5000 6.2 is changed to
align all SNMP trap control to the new „notification control‟ method. Previously on the Ethernet
Routing Switch the following functions used this new method: DHCP Snooping, Dynamic ARP
Inspection (DAI) and IP Source Guard (IPSG).
The new trap support is based on the bsncNotifyControlTable where each application registers its
trap(s) with the table. Each application when registering new traps will set the configuration
change flag, so that if autosave is enabled, the new traps will be saved to NVRAM when
autosave next executes.
By default, all traps are enabled. Entries in the bsncNotifyControlTable are pre-created, you can
not add or delete entries in the table; you can only control if the application will generate SNMP
traps.
If a PoE unit is present or is present in a stack, then three PoE specific trap notifications

will be present: pethPsePortOnOffNotification, pethMainPowerUsageOnNotification,
pethMainPowerUsageOffNotification
The Rapid Spanning Tree (RSTP) specific traps are not available when operating in the

Avaya STG or the MSTP modes. If you have configured RSTP notification types and
change the switch operational mode, the previous RSTP notification types are saved in
the configuration, though will not be displayed in non RSTP mode.
The previous application specific SNMP trap commands are now hidden, so that customers
should use the new notification control commands.

[no] mac-security snmp-trap

[no] [default] snmp-server authentication-trap

[no] [default] spanning-tree rstp traps
The „[no] [default] snmp trap link-status‟ is still an available CLI command as it provides per port
control which is not provided by the SNMP trap Notification control.
The following command displays the various notification type names and the status showing if the
notification control is enabled or disabled.

ERS-Stackable# show snmp-server notification-control
The following commands either enables or disables a notification control type. Please note, the
word entered can either be any one of the SNMP descriptions displayed when the show snmp-
server notification-control command is issued or the OID of a supported notification type. EDM
can be used to view both the notification type name and OID where the CLI only shows the name.

ERS-Stackable(config)# snmp-server notification-control <word>

ERS-Stackable(config)# no snmp-server notification-control <word>
