All,
With the bible in my right hand I pray for all you guys struggling to get
that Number for any personal reason (money, work, etc).
But today is not for talking a religion topics, but for a Question about
allowing Vlans over a trunk
This particular mooning, while doing Lab 3 of NMC I've found the following
"On the trunks allow only the VLAN's involved in this scenario."
Solution show us that, f0/8 is assigned to Vlan 10 and also Vlan 60?? Hmmmm
maybe typo.
Say for example: That you have this task in your Real lab: "Task tells you
to Restrict the traffic crossing the trunk to the VLANs used", for sure I
will get 0 for this one, if put other vlans allowed in the trunk, I'm 100%
sure about that
Other question that arises from this particular Allowed Vlan Situation, is
the should VLAN 1 be allowed in the trunks??? , knowing that even from the
neighbor switch no one is connected to that VLAN1?.
AFIAK removing Vlan 1 from the dot1q trunk, All Traffic leaving would be
tagged, so all layer 2 traffic control (CDP;DTP;etc) is going to leave the
port also with a TAG (just like other vlans traffic passing throe the
trunk), but what is the remote end is not cisco? .- I'm Not looking for the
Scientific Proof Of The Pre-Existence Of Chickens but some opinions about
this topic is highly appreciated
By the way, Lab3 NMC for task 3.2.3 should be:
(config)# interface range f0/13 14
(config-range)# switchport encapsulation dot1q
(config-range)# switchport trunk allowed VLAN 30,60
not 10
