going for the lab date

Filed under: Allgemein — ocsic @ 12:39

I`m not so very motivated. Learning is quite hard. I had the time, that i could not configure the easiest things. I was confused about setting up frame-relay dlci`s. But this time has gone. I still have about some weeks to go. My lab date is not booked yet. My company was giving me about a week for learning so far. Will see how this will be in the next weeks. I will be in the office next week in at a customers site the week after. From the workload it should be possible to have 1 or two days extra for learning. But i will see.

I got also extra online rack time sponsored for my favorite racks provider. Seems like everything is working fine, but the devil is in the detail always. 🙂 I just apprechiate the next weeks. Will get some day`s off at the beginning of may definitely. Spring is about to come and for me this is the nicest season of the year. Do some bicycling for now. Have a great day too.

VTP version 2 and vtp messages regardless domain name

Filed under: Bridging + Switching — ocsic @ 20:39

This should work, but is i labbed it out, it does not as promised. Let`s say if you have a vtp domain CISCO and one switch, that is configured in transparent mode, does belong to another domain, does not forward, these vtp messages. If you have this one switch in between the others, your vlan database will not be updated because of this domain mismatch.

This should work with vtp version 2, but does not, is i tried it today on my rack with 3560 cat switches. For vtp version 1 this behavior is normal.
