The ios version must be consistent with the dedicated stack module and stack cable, and the maximum number of stacks is 9.
Ii. Stack advantages:
High-density ports, easy to manage, and stacked switches can be regarded as a unified configuration of a
Found that Cisco Catalyst Switch reboot is always in rommom mode, the system reboots when the Confreg command chooses the startup mode of 1 (starting from the first file) and cannot enter the normal interface.
Enter to boot:
0 = Disable Autoboot
1 = the internal flash device

"hard" operations on network devices. The security factor is high, but the obtained information is not accurate. For example, if the IP address of a server has been changed, we can think that the server is not connected to the network because the original IP address cannot be found on the switch. The system administrator first checks the IP address information on the server, and then finds out which port of the s

After the FLASH space is insufficient, I specially query the hardware configuration of the 6509 core device. The default Flash of the 6509 standard configuration is 64 MB, and the standard IOS size is 32.1 MB, the IOS 12.2 (17a) SX version to be upgraded has a size of 40.6 MB. In this case, it seems that the space is insufficient. However, this problem is well solved. The original IOS in Flash is deleted and then uploaded. So enter the command: Router # delete sup-bootflash: s72033-pk9sv-mz.122-
