Resolving issues arising during booting of Cisco® router
What are the different ways to boot Cisco router?
Cisco is one of the most reputed brands that manufactures networking products. The routers of Cisco can achieve a data rate of around 92 terabits per second which is the highest that routers have ever reached. A router is a networking device that receives data signals that are then sent or routed to other devices. The bootup process of Cisco routers usually consist of four to five phases. Performing of POST constitutes the first phase of the bootup process. It is the primary step wherein the several hardware components in a system are diagnosed from the ROM. The next phase is the copying of the bootstrap program from ROM into RAM that locates the Cisco IOS program to load it in the RAM. The third phase of the bootup process invloves locating and loading IOS software from the Flash memory or TFTP. This is followed by the final phase that includes locating and loading the configuration file. Thus, the bootup process is completed.
Different ways to fix issues related to bootup process:
- Verifying compatibility of line card
- Resolving booting issue on line card
- Troubleshooting commands
Verifying compatibility of line card
It is important to verify whether the line is supported in the Cisco IOS software version that is used. A software advisory tool can be employed for this purpose. If the card is supported, proceed with configuring and power cycle and in case of incompatibility, enough memory space has to be created in the card in order to resolve the issue.
Resolving booting issue on line card
After this, verify the stage where the line card is stuck during the boot process by using the 'Show led' command. If the output command is MEM INIT, re-seating of the memory on the line card is recommended and in case of MRAM output, the line card must be reseated if it is seated improperly in the slot. It is also advised that you check whether the appropriate CFC and SFC numbers are there in the chassis.
The corrupted commands of the Cisco IOS software can lead to problems in the bootup process that can be rectified by troubleshooting the commands. This is done by re-entering the show version, show led, show diags and show monitor event trace slot-state. The re-entering of the commands can help resolve the issues that are related to the commands of the Cisco router.
