NETGEAR 8800 User Manual

• Upload event logs stored in memory buffer or NVRAM to a TFTP server

• Display counts of event occurrences, even those not included in filter

• Display debug information using a consistent configuration method

EMS supports IPv6 as a parameter for filtering events.

Sending Event Messages to Log Targets

You can specify seven types of targets to receive log messages:

• Console display

• Current session (Telnet or console display)

• Memory buffer (can contain 200 to 20,000 messages)

• NVRAM (messages remain after reboot)

• Primary MSM/MM (for modular systems)

• Backup MSM/MM (for modular systems)

• Syslog host

The first six targets exist by default; but before enabling any syslog host, you must add the

host’s information to the switch using the

configure syslog command. NETGEAR EPICenter

can be a syslog target.

By default, the memory buffer and NVRAM targets are already enabled and receive

messages. To start sending messages to the targets, use the following command:

backup-msm | backup-node| session | syslog [all | <ipaddress> | <ipPort>] {vr

<vr_name>} [local0 ... local7]]]

After you enable this feature, the target receives the messages it is configured for. See Target

Configuration on page 216 for information on viewing the current configuration of a target.

The memory buffer can contain only the configured number of messages, so the oldest

message is lost when a new message arrives, when the buffer is full.

To stop sending messages to the target, use the following command:

disable log target [console | memory-buffer | nvram | primary-msm | primary-node

| backup-msm | backup-node | session | syslog [all | <ipaddress> | <ipPort>] {vr

<vr_name>} [local0 ... local7]]]

Note: See your UNIX documentation for more information about the

syslog host facility.

Primary and Backup Systems

A system with dual MSMs/MMs (modular switches) keeps the two systems synchronized by

executing the same commands on both. However, the full data between the EMS servers is
