You can set maximum 16 SNMP trap hosts with inputting one by one.
The following is an example of setting an SNMP trap host.
SWITCH(config)# snmp trap-host 10.1.1.3
SWITCH(config)# snmp trap-host 20.1.1.5
SWITCH(config)# snmp trap-host 30.1.1.2
SWITCH(config)#
7.1.12.3 Enabling SNMP Trap
The system provides various kind of SNMP trap, but it may inefficiently work if all these
trap messages are sent very frequently. Therefore, you can select each SNMP trap sent
to an SNMP trap host.
• admin-access-login is shown to notify the administrator that the system is accessed
by SNMP. The system leaves the login information by syslog when it is logged by tel-
net or console. When the system is accessed by SNMP, it regards the connection as
having been maintained for the connection valid time (300 seconds). During the time,
the system is accessed by SNMP from the same origin, the connection time will be
refreshed to 300 seconds. If there is no SNMP access during the time (300 seconds),
the system regards that the connection is invalid. After that, if the system is accessed
by SNMP again, the trap will be generated again.
• authentication-failure is shown to inform wrong community is input when user trying
to access to SNMP inputs wrong community.
• cold-start is shown when SNMP agent is turned off and restarts again.
• cpu-threshold is shown when CPU utilization exceeds the threshold specified by
user. Also, when CPU load falls below the threshold, trap message will be shown to
notify it.
• dhcp-lease is shown when no more IP address is left in the DHCP pool. Even if this
occurs only in one DHCP pool of several pools, this trap message will be shown.
• dying-gasp is shown when a power outage of any downstream equipments occur
with a critical error.
• link-up/down is shown when network of port specified by user is disconnected, or
when the network is connected again.
• login-failed is shown in case of a security violation (failed login, unauthorized SNMP
query).
• memory-threshold is shown when memory usage exceeds the threshold specified
by user. Also, when memory usage falls below the threshold, trap message will be
shown to notify it.
• port-threshold is shown when the port traffic exceeds the threshold configured by
user. Also, when port traffic falls below the threshold, trap message will be shown.
• system-restart is shown to inform the system rebooting.
• trap-log is shown when the trap logs are more than 90% full and will wrap around
soon.
The system is configured to send all the SNMP traps as a default.
