3 1. Utilization Alarm 1.1 Overview for Utilization Alarm The device utilization alarm function is used to monitor the bandwidth of the device, CPU resource consumption, and generate alarm notification in the event of congestion, so that the administrator can keep abreast of the network and equipment running. The port utilization alarm function can set two trigger alarm thresholds. The detailed description is as follows: exceed:when the port bandwidth utilization equals or exceeds the "exceed" value, a congestion alarm is triggered. normal: When the port bandwidth utilization falls below the "normal" value, the recovered alarm is triggered. CPU utilization alarm function can also set two trigger alarm thresholds, described in detail as follows: busy: When the CPU utilization equals or exceeds the "busy" value, an alarm is triggered, indicating that the CPU is busy. unbusy:when the CPU utilization is equal to or lower than the "unbusy" value, an alarm is triggered, indicating that the CPU is idle. The alarm information is output to Syslog by default. If you want to output to the terminal, you need to enable the command. 1.2 Utilization Alarm Configuration Configure the Port Utilization Alarm Configure the Port Utilization Alarm Enter global configure terminal mode Enable/disable [no] alarm all-packets alarms on all ports 1

7 1.4 System Log System Log Overview Syslog is the system information center, to complete the unified processing and output of information. The other modules in the system will send the output information to Syslog. Syslog determines the output format of the information according to the of the user and outputs the information to the specified display device according to the information switching and filtering rules of each output direction configured by the user. With the Syslog information producer, which is each module of output information, you do not need to export information to the console, Telnet terminal, or log host (Syslog server). You only need to output the information to Syslog. By configuring the appropriate filtering rules, information consumers, which are console, Telnet terminal, history buffer, log host and SNMP agent, can choose whatever they want to receive the information they need and discard unwanted information System Log Configuration 1) Enable/disable Syslog Enable/disable Syslog Enter global configure terminal mode Enable/disable log [no] logging function View the information Show logging 5

8 The logging function is enabled by default and stored in the buffer. 2) Configure the Log Serial Number Configure the Log Serial Number Enable/disable [no] logging sequence-numbers the log serial number The logging function is enabled by default. 3) Configure the Timestamp Configure Syslog Timestamp Configure the logging timestamps { notime uptime datetime } timestamp type Recover the no logging timestamps default There is no separate timestamp switch. There are three timestamp types: notime: do not show the time; uptime: show the boot time; Datetime: show the date and time. The default is uptime. 4) Output to the Terminal In privileged mode, configure the log to output to the terminal switch. In global mode, you 6

9 can configure information display and filtering rules. By default, the device logs are not output to the terminal, but output to the buffer. There is a slight difference between the command for the serial terminal and the Telnet or ssh terminal. Output to the Terminal User end mode Enable/disable [no] terminal monitor output to the terminal Global configure terminal mode Enable/disable log [no] logging monitor { all monitor-num } display logging monitor { all monitor-num } { level-value none Configure the level-list { start-level to end-level value } } [ module filtering rules module-name ] View the filtering show logging filter monitor monitor-num rules Delete the filtering rule no logging monitor { all monitor-num } filter 1. Log output to the terminal: In the serial console, the default is terminal monitor; in other terminal console, the default is no terminal monitor; 2. Log information display: In the non-console terminal, only affect this landing of the current terminal, the other terminals, the next landing of the current terminal is invalid; 3.monitor-num is 0 for the console, and 1 to 5 for Telnet and ssh terminals. 4. Output log default rule: all modules, log level 0-5,7. Deleting the filtering rule restores the default rule. 5) Output to Buffer Output Syslog to Buffer Enter global configure terminal mode Enable/disable [no] logging buffered 7

10 output to buffer Configure the filtering rules View the filtering rules Delete the filtering rule View the log information in the buffer logging buffered { level-value none level-list { start-level to end-level value } } [ module module-name ] show logging filter buffered no logging buffered filter Show logging buffered [ level-value level-list { start-level to end-level value } ] [ module module-name ] The default is log output to buffer. The default rule is to output all modules and logs at the level 0-6. Deleting the filtering rule restores the default rule. 6) Output to Flash In global mode, you can configure Syslog to save to Flash, which is not saved in flash memory by default. Output Syslog to Flash Enter global configure terminal mode Enable/disable output [no] logging flash to flash Configure the filtering logging flash { level-value none level-list { start-level rules to end-level value } } [ module module-name ] View the filtering rules show logging filter flash Delete the filtering rule no logging flash filter Configure the save [no] logging flash interval value period Configure the log size [no] logg flash msg-number value to be saved each time Check the log Show logging flash [ level-value level-list { start-level to information in the flash end-level value } ] [ module module-name ] 8

11 1. When the log is output to flash, the default rule is to output all modules and the log level is 0-5. Deleting the filtering rule restores the default rules. 2. When the log output to flash, the default cycle is 30M. By default, 100 logs are saved at one time. 7) Output to External Server Configure the specified server address for log output, information output switch, filtering rule, and logging tool and source address in global mode. Output Syslog to External Server Enter global configure terminal mode 必先 Configure the log server [no] logging ip-address Enable/disable the log server [no] logging host { all ip-address } Configure the filtering rules Recover the default filtering rules Configure the logging tool name Configure the sip for log packet logging host { all ip-address } { level-value none level-list { start-level to end-level value } } [ module module-name ] no logging host { all ip-address } filter [no] logging facility { clock1 clock2 ftp kernel lineprinter localuse0 localuse1 localuse2 localuse3 localuse4 localuse5 localuse6 localuse6 localuse7 logalert logaudit mail networkknews ntp security1 security2 syslogd system userlevel uucp } [no] logging source { ip-address loopback-interface if-id } 1. The sip of log messages must be the interface of the device. The Layer 3 device uses the IP address of the corresponding interface of the log server by default. The Layer 2 device automatically uses the system IP and does not need to be configured. 2. The default logging tool name uses localuse7. 9

12 8) Output to the SNMP Agent Configure Syslog output to the SNMP agent in global mode. To send Syslog messages to SNMP Workstation in trap messages, you must also configure the Trap host address. Refer to the SNMP instructions. By default, logs are not output to the SNMP agent. Output Syslog to SNMP Agent Enable/disable log output to the snmp agent [no] logging snmp-agent Configure the logging snmp-agent { level-value none level-list filtering rules { start-level to end-level value } } [ module module-name ] View the filtering show logging filter snmp-agent rules Recover the default filtering rules no logging snmp-agent filter 1. Log output to the snmp agent, the default rule: output all modules, the log level is ) Debugging Function In the global mode, you can configure the debugging function to print the debugging information of the corresponding module. By default, debugging information of all modules is disabled. Configure the Debugging Function Enable/disable [no] debug { all module-name } debugging function View the information show debug 10
