Associates a filter to a target.
In a stack, this command is applicable only to Master and Backup nodes. This command is not applicable to standby nodes.
| target | Specifies the device to send the log entries. |
| console | Specifies the console display. |
| memory-buffer | Specifies the switch memory buffer. |
| primary-node | Specifies the primary node in a stack. |
| backup-node | Specifies the backup node in a stack. |
| nvram | Specifies the switch NVRAM. |
| session | Specifies the current session (including console display). |
| syslog | Specifies a syslog remote server. |
| all | Specifies all of the syslog remote servers. |
| ipaddress | Specifies the syslog IP address. |
| ipPort | Specifies the UDP port number for the syslog target. |
| vr_name | Specifies the virtual router
that can reach the server IP address. Note: User-created VRs are supported only on the platforms listed for
this feature in the
Switch Engine v33.1.1 Licensing Guide
document.
|
| local0 ... local7 | Specifies the local syslog facility. |
| filter-name | Specifies the filter to associate with the target. |
| severity | Specifies the minimum severity level to send (if the keyword only is omitted). |
| only | Specifies that only the specified severity level is to be sent. |
If severity is not specified, the severity level for the target is left unchanged. If a virtual router is not specified, VR-Mgmt is used.
This command associates the specified filter and severity with the specified target. A filter limits messages sent to a target.
Although each target can be configured with its own filter, by default, all targets are associated with the built-in filter, DefaultFilter. Each target can also be configured with its own severity level. This provides the ability to associate multiple targets with the same filter, while having a configurable severity level for each target.
A message is sent to a target if the target has been enabled, the message passes the associated filter, the message is at least as severe as the configured severity level, and the message output matches the regular expression specified. By default, the memory buffer and NVRAM targets are enabled. For other targets, use the command enable log target. The following table describes the default characteristics of each type of target.
| Target | Enabled | Severity Level |
|---|---|---|
| console display | no | info |
| memory buffer | yes | debug-data |
| NVRAM | yes | warning |
| session | no | info |
| syslog | no | debug-data |
The built-in filter, DefaultFilter, and a severity level of info are used for each new telnet session. These values may be overridden on a per-session basis using the configure log target filter command and specify the target as session. Use the following form of the command for per-session configuration changes:
configure log target session filter filtername {severity severity {only}}Configuration changes to the current session target are in effect only for the duration of the session, and are not saved in FLASH memory. The session option can also be used on the console display, if the changes are desired to be temporary. If changes to the console-display are to be permanent (saved to FLASH memory), use the following form of the command:
configure log target console filter filtername {severity severity {only}}The backup-node target is only active on the primary-node, and the primary-node target is active on backup-node and standby-nodes.
The following example sends log messages to the previously syslog host at 10.31.8.25, port 8993, and facility local3, that pass the filter myFilter and are of severity warning and above:
configure log target syslog 10.31.8.25:8993 local3 filter myFilter severity warning
The following example sends log messages to the current session, that pass the filter myFilter and are of severity warning and above:
configure log target session filter myFilter severity warning
This command was first available in ExtremeXOS 10.1.
The ipPort parameter was first available in ExtremeXOS 11.1.
The udp-port parameter was added in ExtremeXOS 21.1.
This command is available on all Universal switches supported in this document.
