1.When I type the CLI command: statistics ip, I receive a list of counters with numbers. What is the meaning of those counters? The following CLI command: LinkProof#statistics ip
Will result in the following output: ────────────── IP Counters ──────────────── ipInReceives 123863 ipInHdrErrors 594 ipInAddrErrors 0 ipForwDatagrams 0 ipInUnknownProtos 14674 ipInDiscards 51622 ipInDelivers 117430 ipOutRequests 123 ipOutDiscards 0 ipOutNoRoutes 6435 ipReasmReqds 0 ipReasmOKs 0 ipReasmFails 0 ipFragOKs 0 ipFragFails 0 ipFragCreates 0
Resolution ipInHdrErrors – represents ipInHdrErrors – represents the number of input datagrams discarded due to errors in their IP headers, including bad checksums, version number mismatch, other format errors, timeto-live exceeded, errors discovered in processing their IP options, etc. For more information you can add the argu ment “hdrErr” which lists specific IP header errors. ipInUnknownProtos - RFC 1213 defines the entry as “The number of locally -addressed ipInUnknownProtos datagrams received successfully but discarded because of an unknown or unsupported protocol. ipInDiscards - The number of input IP datagrams for which no problems were encountered ipInDiscards to prevent their continued processing, but which were discarded. For example: due to lack of buffer space.
2. SNMP
traps output. If you are using a CLI remote connection (through SSH or Telnet) issue the
command: manage terminal traps-output set 2 to print all of the console‟s message
3. High RS CPU Queries Perform the following procedure to help you to track the task that is consuming CPU resources: 1. Connect to the device using a console, and log the console's output in a file. 2. Enable the task utilization monitor using the command s ystem internal task-utilization monitor
3. Run the command s ystem internal task-utilization show 4. Check which task is consuming the CPU resources (ignore the RE task). 5. Run the command system os tasks 10 times. 6. Send the console's output file and the support file to Radware Technical Support. Models: 100/200/202/1000/3020/6000 Device Information Device serial number and/or MAC address for service agreement validation and hardware identification.
Output Information Generate the following output: 1. Support files from all Radware devices involved in the setup. To download a support file from the Web Management Management, select File > Support, and click Download. If you are using AppDirector version 1.06.05 or earlier, go to Step 2. 2. If the support files were provided in step 1 skip this step. Issue the following CLI commands through the console connection: system device-info system logfile
For AS3 or AS4 platforms, also provide the following logs: system internal accelerator data log-print cpu0 system internal accelerator data log-print cpu1
3. Configuration files for all devices in .ber and .txt (ASCII) formats. 4. Error and/or Info messages printed by the device. 5. SNMP traps output. 6. Sniffer traces if relevant, taken simultaneously from both sides of the Radware device.
7. Boot (EPROM) version information. If possible, reboot the device and capture the console output while the device loads up.
Issue Description 1. Detailed description of the issue and the user experience. 2. Steps to reproduce the issue. 3. When did the issue begin? 4. Was there a change in the configuration that triggered the issue? 5. Was there any specific traffic or test running when the problem occurred?
Environment Information 1. Basic logical diagram of the network, including IP addresses of Radware devices and IP addresses of surrounding devices that are relevant to this case. 2. Other relevant information: OS, Web server vendor, application servers, firewalls, cache servers, routers, and switches (version of all these devices if possible). In cases of CPU and performance issues, at the time of the problem occurrence, issue the following commands: • net route fast-forwarding-table • net l2-information • net arp table • net bridge forwarding -table • system os cpu • system inf-stats (Reset the counters 1st by -system inf-stats reset) • system os buffers, system os tasks • system internal bridge-fft • system internal arp-wait-list • system internal icmp -counters • system internal driver stat all • system internal driver macstat
Is it possible to view the configuration through CLI? Is it possible to upload configuration
settings to the device using CLI?
It is possible to view the configuration of a device using Command Line Interface (CLI). The CLI can be a direct serial connection, Telnet, or SSH access. To view device configuration through CLI, use the CLI command system config. This command displays the running configuration (real and online configuration) of the device in the form of terminal commands. This means that if you copy and paste one of the lines into the CLI prompt – the command will be executed. Press the space bar to scroll down the page. Press Enter to scroll down line by line. How do I upload configuration settings using CLI? 1. To start the upload configuration process, enter: system paste-config start 2. Paste the selected commands from the output of the 'system config' command into the destination device. 3. To finish the configuration process, enter: system paste-config stop Please Note: Long statements in the output are broken using the line-continuation character (\ as the last character of a line).
I‟m trying to view the configuration using command: „system config immediate‟ but I receive an error message. Why? Symptom The CLI (RS-232, Telnet or SSH) command “system config immediate” is used to view the device configuration in real time in prompt command format. The follwing error message is printed: "Can't open the configuration file due to following reason: The configuration file is currently being used by a second user. Please try later." Possible reason The following error message is printed if the command is executed more than once, while the device is managed by more than a single CLI connection at a time. For example, one Telnet session and one SSH session at the same time, or two Telnet sessions or two SSH sessions at the same time. The error message may also appear in cases where the configuration is viewed using one of the CLI methods while trying to retrieve the configuration file using Web Based Management.
It is possible to execute this command twice at the same time only in cases where RS-232 (console) and Telnet session or RS-232 and SSH session are connected to the device.
Note: In order to view the configuration properly using CLI, it is recommended to enable the more prompt. If the More prompt is ON, the user is prompted for more output when the bottom of the display area is reached. If the More prompt is OFF, no such prompt appears.
To view the current status of More prompt, at the prompt type: wsd#manage terminal more-prompt
To Enable/Disable the More prompt, at the prompt type: manage terminal more-prompt set [value]
Allowed values are: 1 – On 2 – Off
