ICX Stack Troubleshooting

Troubleshooting stack interactive-setup

7. Check to be sure you do not have any stacking to non-stacking connections. All platforms use proprietary link
negotiation to detect whether a stacking port's neighbors are also stacking ports. The platforms then convert both sides
from IEEE mode (used in data ports) to HiGig mode (used in internal ports). Under stable conditions, both ends of a
stacking link are converted to HiGig mode. If a stacking port is UP but in IEEE mode, its neighbor is not a stacking port.
Enter the show stack stack-ports command to check if any stacking port is UP but in IEEE mode. The following example
shows that U3 ports 3/2/1 to 3/2/3 are UP and in IEEE mode as indicated by the up* mark.
ICX7750-26Q Router(config-unit-3)# show stack stack-ports

U# Stack-port1
1 up 1/2/1 to 1/2/3
up ports: 1/2/1, 1/2/2, 1/2/3
up ports: 1/2/4, 1/2/5, 1/2/6
2 up 2/2/1 to 2/2/3
up ports: 2/2/1, 2/2/2, 2/2/3
up ports: 1/2/4, 1/2/5, 1/2/6
3 up* 3/2/1 to 3/2/3
up ports: 3/2/1, 3/2/2, 3/2/3
up ports: 3/2/4, 3/2/5, 3/2/6
Note: *: Port is up in IEEE mode, not in HiGig mode.
8. If you run out of flash memory while performing a write memory, your stack devices may contain very large startup-
config.v4 or startup-config.old files, which are preserved for recovery purposes. Enter the show dir command at the
privileged EXEC level to see all flash files. If you identify these old files and they are not needed, you can delete them by
entering the flash delete command at the privileged EXEC level as shown in the following example.
ICX7450-48F Router# show dir
