Configuring the SNMP server hosts

NOTE

The Audit log messages are not converted into swEventTrap.

The SNMP traps are unreliable because the trap recipient does not send any acknowledgment
when it receives a trap. Therefore, the SNMP agent cannot determine if the trap was received.

Brocade switches send traps out on UDP port 162. To receive traps, the management station IP
address must be configured on the switch. You can configure the SNMPv1, SNMPv2c, and SNMPv3
hosts to receive the traps. For more information, refer to

“Configuring the SNMP (version 1 or

version 2c) server host”

on page 9.

SNMP informs

An SNMP inform is similar to the SNMP trap except that the management station that receives an
SNMP inform acknowledges the system message with an SNMP response PDU. If the sender does
not receive the SNMP response, the SNMP inform request can be sent again. An SNMP inform
request is saved in the switch memory until a response is received or the request times out. The
SNMP informs are more reliable and they consume more resources in the device and in the
network. Use SNMP informs only if it is important that the management station receives all event
notifications. Otherwise, use the SNMP traps.

Brocade devices support SNMPv3 informs. For more information, refer to

“Configuring the SNMPv3

server”

on page 9.

Port logs

The Network OS maintains an internal log of all port activity. Each switch maintains a log file for
each port. Port logs are circular buffers that can save up to 8,000 entries per switch. When the log
is full, the newest log entries overwrite the oldest log entries. Port logs capture switch-to-device,
device-to-switch, switch-to-switch, some device A-to-device B, and control information. Port logs are
not persistent and are lost across power cycles and reboots.

Port log functionality is completely separate from the system message log. Port logs are typically
used to troubleshoot device connections.

Configuring the SNMP server hosts

Network OS v4.1.1 supports SNMP version 1, version 2c, and version 3. Use the commands listed
in

Table 4

to configure the SNMPv1, SNMPv2c, and SNMPv3 hosts and their configurations.
