Here i have a 3-switches Catalyst 2960XR stack which were newly purchased.
I tried upgrading their IOS from 15.2(2) to 15.2(7), after finished upgrading, i also reloaded the stacked machines.
But after that my console screen will show as below:
File "flash:c2960x-universalk9-mz.152-7.E2.bin" uncompressed and installed, entry point: 0x3000executing
Press RETURN to get started!
% % Duplicate sequence number.
%Failed to add ace to access-list% % Duplicate sequence number.
%Failed to add ace to access-list
I have no idea how to deal with it, is there anyone who met the same symptom before??? and how to resolve???
