Unable to access 5406zl console/telnet

Greetings

We recently expanded our 5-switch LAN to 9 switches, all 5406zl, all updated to ver K.13.23 at the same time as the expansion. Since the expansion, we are intermittently unable to access the switch, neither via TELNET nor via the CONSOLE.

Despite the above, all switches are fully operational. Access is restored when we reboot the switch.

Anyone out there available to assist?

This was fixed in K.13.25. It was caused by TFTP broadcast requests. You can also workaround it by using the 'no tftp server' command.

Hello guys.
sorry for this interrupt, but I am also experiencing same issue. Could you telling me the cause effected on K.11.63 ??

It'd be a different bug on K.11.63. I'd also update it to K.13.25 and monitor.
