In Service Software Upgrade ISSU on CE6800 switches

Created May 31, 2015 07:20:53Latest reply Jul 10, 2015 11:35:13 1991 1 0 0

I am aware that there is the ability to perform a smooth firmware upgrade on CE6800 switches that are stacked with iStack.

Are there any plans to improve In Service Software Upgrade ISSU on CE6800 (single supervisor) switches? I am interested to know if I will be able to upgrade the complete firmware on a CE switch without interrupting packet forwarding at all.

I understand there is the ability to hot-patch on the CE6810, does that also enable complete firmware upgrade without interrupting packet forwarding on an individual switch?

Is the switch operating system on the CE6800 based on linux? I understand new version so lunix will enable OS upgrades without reboots, so am wondeing if the same will eventually apply to the CE6800 operating system.

Thanks, Simon

CEseries Switch support ISSU, but only support some software version.  Such as  from V1R3C00 to V1R5C00, from V1R5C00 to V1R5C10.

also CE6800 switch does not support single switch ISSU now,it only support CE6800 stack system.

Linux support upgrade software version without reboot, but such as interface chip and other chips update firmware can not upgrade without reboot.
