Please make sure that either logging console or logging buffered is enabled while doing the troubleshooting section.
I have noticed in several occasions while doing INE TS labs that neither of these commands were enabled by default and I was doing RIP debugging troubleshooting.
I thought that RIP is not seding an updates as it is believed to be slow protocol:-)...But later I realized that the updates were there but they were not being shown.

In many occasions, I have noticed that if we do not shut the physical interfaces before creating Ether Channels, so as soon as the interfaces are added in the channel, they shutdown (actually err-disabled). It should be the best practice to shut the interfaces that we need to add in the Ether Channels, before adding them in the channel-group.
Why I mentioned this because I keep on troubleshooting the problem of Ether Channel not coming up and I realize that the physical interface it self is shut.

You may have shut down a link or expected a link failure but seen "sh cdp neigh" still displaying an active connection, well that is all due to the CDP Holdtime. It has to run down to 0. The default is 180 seconds, which can certainly lead to some confusion if you are troubleshooting a recently failed link. The default can be changed with the "cdp holdtime" global parameter. Once you're used to looking for it, you can see that the holdtime is unusually low for the failed link, which should lead you to figure it really is down w/out waiting for the entire holdtime to exp ... read more »

I think i can study most of the technologies using emulated devices and i successfully emulated IPS, Router, ASA . The only missing piece is Switch. i think i can do the practicals on that from somewhere else. I think this community also help me to achieve my goal.
