Modifying the SNMP Engine ID
Netvisor ONE allows you to modify the SNMP Engine ID and retrieve previous SNMP agent information for a switch no longer in use. If you have to remove a switch from the network, you can modify the SNMP Engine ID to use the old SNMP Engine ID so Netvisor ONE can query and maintain the same history records for the new switch.
(CLI network-admin@Spine1)>snmp-engineid-modify
 
engineid string
Specify the 28 character unique ID for the SNMP engine.
(CLI network-admin@Spine1)>snmp-engineid-modify engineid 0x80001f8880077f7820da49395a00000000
Warning: All SNMP users will be erased.

Additional SNMP commands supported:
snmp-engineid-showThe SNMP engine ID is a unique string of 24 characters that identifies the device for administrative purposes. This command displays the identification of the local SNMP engine and all remove engines configured on the switch.
snmp-trap-enable-modify — Used to enable notifications about link conditions and common system errors. This is used with the snmp-monitor commands.
snmp-trap-enable-show — Display enabled SNMP traps.
snmp-trap-sink-create — Used to specify a SNMPv1 trap receiver.
snmp-trap-sink-delete — Delete SNMP trap sinks
snmp-trap-sink-modify — Modify SNMP trap sinks.
snmp-trap-sink-show — Display SNMP trap sinks.
snmp-v3-trap-sink-create - Used to specify a SNMPv3 trap receiver.
snmp-v3-trap-sink-delete — Used to delete a SNMPv3 trap receiver.
snmp-v3-trap-sink-delete — Used to delete a SNMPv3 trap receiver.
snmp-v3-trap-sink-modify — Used to modify a SNMPv3 trap receiver.
snmp-v3-trap-sink-show — Used to display a SNMPv3 trap receiver.
SNMP Traps
SNMP MIBs send traps when a link becomes congested and when a node state in the fabric changes.
Link congestion can be detected when Netvisor ONE drops ingress or egress packets due to link congestion. Netvisor ONE logs this information into the system logs and you can enable Netvisor ONE to send “Link Congestion detected” SNMP traps.
When Netvisor ONE detects a fabric node as dead or keepalives are detected, Netvisor ONE checks the previous state of the node and determines if the previous state was online or offline. SNMP sends out traps as “Node status changed.”
To enable the traps, use the snmp-trap-enable-modify command:
CLI (network-admin@Spine1)snmp-trap-enable-modify
one or more of the following options:
link-up-down|no-link-up-down
Specify if you want to enable a link up|down trap.
