NETGEAR 8800 Chassis Switch CLI Manual • Numerals (0-9) • Period ( . ) • Dash ( - ) • Underscore ( _ ) • Slash ( / ) Permitted only for remote files When naming a local or remote file, remember the requirements listed above. Virtual Router Requirements The vr_name option specifies the name of the virtual router. The valid virtual router names at system boot-up are VR-Mgmt, VR-Control, and VR-Default; however, you can TFTP only on VR-Mgmt and VR-Default. On the NETGEAR 8800 switch, you can also create and configure your own virtual routers. For more information about virtual routers, see the section "Virtual Routers" in the NETGEAR 8800 User Manual. Internal Memory and Core Dump Files Core dump files have a .gz file extension. The filename format is: core..gz where process-name indicates the name of the process that failed and pid is the numerical identifier of that process. If you save core dump files to an external memory card, the filename also includes the affected MSM/MM: MSM-A or MSM-B. If you configure and enable the switch to send core dump (debug) information to the internal memory card, specify the internal-memory option to transfer those files from the internal memory card to a TFTP server. You can also transfer core dump information to and from an external compact flash card. If the switch has not saved any debug files, you cannot transfer other files to or from the internal memory. For example if you attempt to transfer a configuration file from the switch to the internal memory, the switch displays a message similar to the following: Error: tftp transfer to internal-memory not allowed. For information about configuring and sending core dump information to the internal memory card, see the configure debug core-dumps and save debug tracefiles memorycard commands. For more detailed information about core dump files, see the troubleshooting appendix in the NETGEAR 8800 User Manual. If you specify the memorycard option, you can copy and transfer files to and from the external memory card using TFTP. Other Useful Commands To upgrade the image, use the download image command. This command utilizes TFTP to transfer the software image file from your TFTP server to the switch. For more information about this command, see download image on page 1308. 152 | Chapter 3.
