I want to do upgrade of IOS in the Switch,

using the cards active and standby.

It is possible to do that, so without losing the network service.

The switch have 12.2(18)EW version, and it not support

"In Service Software Upgrade Process" ISSU.

I will change Configuration of the register to 0X2102.I think

that the conf register 0X2101 was configurated

by any troubleshooting, and let so by forgot

Reviewing the configuration of the router i could saw

the following message, the hour 06:33:06 is just when happen

the problem.

That message say that now active engine is 1, and

engine 2 was active before the problem?
