L3 to L2 trunking

Hi guys,

I always thought that if you want say a L3 3550 switch om say port 1 to connection to say port 1 on a L2 2950 switch the port config would be something like this:

3550:

interface fastethernet 0/1
switchport access vlan 100
switchport mode dynamic desirable

2950:
interface fastethernet 0/1
switchport access vlan 100
switchport mode trunk

but I'm sure I'm doing it wrong becasue I can get the link from coming up for down on both ends of the link; if i plug both ports into a unused port on he Procurve switch port boths come up so I know they work.... What am I doing wrong? icon_sad.gif

I'm basically wanting to get the 2950's vlan of 100 to connect to the 3550 so I can route the traffic through the router's. I've been making the network in reverse from the routers to the L3's and now to the L2's and the trunking between the L3's and L2's is my current hurdle.

    If you're only using VLAN 100 you could just set them both to access ports.

    Let's start with this: Why do you have these ports configured with the "access vlan" command? Why "desirable" on the 3550? What kind of cable are you using for this connection?
    Modularity and Design Simplicity:

    Think of the 2:00 a.m. test—if you were awakened in the
    middle of the night because of a network problem and had to figure out the
    traffic flows in your network while you were half asleep, could you do it?

    Well Mr. Murry icon_bounce.gif I'm using normal cat5e cable as uplinks. As for access vlan 100; I'm using that to assign the ports to vlan 100; I don't want them to all be trunks so to me 'access' just means it resides on that vlan as a normal port you can plug anything into it like a laptop and as-long as dhcp is on that vlan it will get a IP, that to me is 'access'.

    Let me counter your question with when would dynamic desirable and auto be used?

    I also think I've made my home lab too complicated! .. if that's even possible.

    I have 3 L3's (2 3550's and 1 3750) each L3 has 3 L2 2950 connected to it and then each L3 switch has a cat5e uplink to the fa0/1 connection on a inter-vlan 2600 router. Then all 3 of the 2600 routers have a OSPF connection between them with a primary serial connection to 2 1721 routers and then both of the 1721 router have a uplink (acting as a MPLS) to another 1721 that connects to the core MDF a HP Procurve.

    .... Little did I know on a flowchart it looks relatively straight forward but getting into the CLi it's al ittle more interesting.... I got 50% of it done, on the routing aspect and to the L3 switches but boy has it been a long day! ....

    ... I'm sure this really overkill for the CCENT/CCNA exam but I really wanted to understand this all well; but something are still hard for me like when to use dynamic desirable and auto and the whole nat inside and nat outside that's still interesting to me...

How can F0/1 on the 2950 be an access port when you have entered the command "switchport mode trunk"? It's either one or the other, there is no mixing the two. So how do you fix that problem?

    Let me counter your question with when would dynamic desirable and auto be used? You would NEVER use that in a production environment. The port should either be an access port or a trunk port.

    I also think I've made my home lab too complicated! .. if that's even possible. It's possibe, congrats! lol Don't fret, it happens..

    In bold above, also do you see a link light on both F0/1 ports? Why not? What kind of cable do you have? There is no 'L3 to L2" trunking, trunking is a L2 feature. You will later delve into things like L3 Etherchannels but that is something else all together.

    You are simply looking to trunk two switches together and allow various VLANS across the trunk links.

    Let me ask this: - on the 2950 if you use 'switchport mode trunk' on fa0/1 wouldn't you need to use 'switchport mode access vlan 100' to assign vlan 100 to that port? - that's my logic, if that logic is wrong please do correct me; learning cisco now so I don't want to get into bad habits...

    as to the activity lights, nope they don't have any activity lights on either on the ports; wait is that a trick question... icon_bounce.gif

    if you never use dynamic desirable and auto why does Cisco make you learn them; what point do they serve?

    A trunk port is used to carry "multiple" VLAN's

    If you have a trunk port on SW1 and that port is connected to SW2, then SW2's port must be a trunk as well. You cannot configure an access port on the other side.

    I'd go read up on trunk ports myself if I were you ;)

    Dynamic Desirable and Auto and DTP in general is an important feature of L2 that Cisco tests on -even at CCIE level. Dynamic Desirable is a horrible default on the 3550 btw.

    RouteMyPacket is trying to nudge you in a different direction because while the config looks unusual, it should technically still work.

    Nothing too complicated about trunks.. Both ends must be a trunk and you can use the allowed trunk setting to set the VLANs that are allowed across it. Also you can set the native VLAN for which untagged frames will be carried across.
    Getting There ...

    Let me ask this: -
    No, it's time for you to read. Cisco has a massive amount of docs online and configuration guides. You have to get use to googling for what you need, you will do that all throughout your career.

    as to the activity lights, nope they don't have any activity lights on either on the ports; wait is that a trick question... Just looking at the older switches you have, wondering if another type of cable may need to be used?

    if you never use dynamic desirable and auto why does Cisco make you learn them; what point do they serve? Why do they make you learn Frame Relay, or RIP for that matter. It's revisionist history. FYI, yes Frame Relay can still be found but it's no longer common.


    In bold, come on..let's see you work this out.

    Well I think I figured it out, i looked back on my notes in my notebook; there is so much to remember for the CCNA so I will admit I'm having a hard time remembering it all... But I think this is how the config should look....kind of silly for me to post it; but meh it's just more easing if you just ask a question, seeing others responces is relaxing.


    Question 1:

    Cisco 3550 L3
    int f1/0/1
    swtichport mode trunk
    Switchport trunk encapsulation dot1q
    switchport trunk allowed vlan 100

    Cisco 2950 L2
    Int f1/0/1
    swtichport mode trunk
    Switchport trunk encapsulation dot1q
    switchport trunk allowed vlan 100

    Question 2:

    I think I catch what you mean; it's like a riddle ot figure some of your qustions out; do you mean if I have any crossover cables? - I'm thinking that the 2950's don't have Auto-mdix cause if they did a normal cat5e would work; is that what you mean? I should use a crossover cable?

    Question 3:

    Well I never knew that, see I'm new to the Cisco world so go easy on me; I'm still learning what is book smarts and what is real-world application. I guess though all of the concepts play a part in the great scheme I thing I hope. Would really suck to learn how to make a nuclear bomb but then never use it, lol ... if you understand the analogy. :)

    Cisco 3550 L3
    int f1/0/1
    swtichport mode trunk
    Switchport trunk encapsulation dot1q
    switchport trunk allowed vlan 100 Why are you using this command? Why use this and not leave it default?

    Cisco 2950 L2
    Int f1/0/1
    swtichport mode trunk
    Switchport trunk encapsulation dot1q Are you sure this command is right?
    switchport trunk allowed vlan 100 Again, why use this command?

    Question 2:

    I think I catch what you mean; it's like a riddle ot figure some of your qustions out; do you mean if I have any crossover cables? - I'm thinking that the 2950's don't have Auto-mdix cause if they did a normal cat5e would work; is that what you mean? I should use a crossover cable? Boom, Bingo, Yes and Yes!

    Question 3:

    Well I never knew that, see I'm new to the Cisco world so go easy on me; I'm still learning what is book smarts and what is real-world application. I guess though all of the concepts play a part in the great scheme I thing I hope. Would really suck to learn how to make a nuclear bomb but then never use it, lol ... if you understand the analogy. :)This is why I advise to use certification as a supplement to experience and not the other way around. Not that it can't be done but it avoids some of the thing you are running into. It's easier to spot the "fluff" in the texts etc IMO when you have been working in the field.

    Well I'm finding you don't need encapsulation on the L2 switch, it doesn't allow me to apply it anyways. and the dynamic desirable goes away is i use encapsulation on the L3 switch so that's neat to know.


    would this be needed: 'switchport trunk allowed vlan 100' to tell this port to accept traffic over this port from a different switch on vlan 100?

    however could this be why now I'm getting this:

    it's kind of funny this is the vlan 100 setup I'm doing now but the other 2950 with vlan 200 is now working fine and it's the exact same config. so I'm curious how the frig I'm getting a VTP mismatch! ... I'm pretty VTP is the protocol that shares vlan across ther switches but I could be wrong...


    btw, ordered 8 more crossover cables.... see how these 2950 suck ass and I'll probably never use them past the CCNA and get all 3550's and above....

    Number one rule when consoling into a new switch, verify VTP

    Do a "sh vtp status" ands paste it here

    Ok, so now that we see the output, what is the problem? How do you fix it?

    Think of the 2:00 a.m. test—if you were awakened in the
    middle of the night because of a network problem and had to figure out the
    traffic flows in your network while you were half asleep, could you do it?

    not going ot quote you or else we'll take up forum data space real quick but....

    I'm thinking I need to clean the vlan.config file? or something like that? ... am I hot or cold?

    ...or enable VTP2? icon_bounce.gif

    here is the other 2950 and it's working fine:

    Ask yourself, what is VTP? How does it function? Why is it configured? I see the 3550 is a "Server" and the 2950 is a "Client", what does that mean?

    I dare say you didn't configure this but it's good exercise.

    I actually did configure it; I thought the 2950 L2 should be the client and the 3550 L3 should be the server.

    To me, the VTP server has the primary list of all of the vlans and such and then shares with list with all of the switches that are clients...

    would it be fair to say if i changed them all to transparent they will work? ... need to find my book to see what the frig the difference is between transparent and client, I could be getting the terminology confused.

    Take a look again at your VTP status on your 3550 and 2950, something seems off between the two. Something doesn't match does it?

    yes, the amount of vlans.

    I've never purged vlan from nvram, how do i purge the list?


    ... i mean i could just google it, but :rolls eyes:

    Nope, what is required to make VTP function? VTP information has to match right? How can VTP function if the domain is different?

    Round 2. ended up turning on the VMware cluster after returning with beer, opened the bottle but got so tied up with VMware labbing I still have the full bottle which is now in the fridge.

    Anyways back to the Cisco labbing this morning; I seem to now have a MD5 checksum error and to me clearly both of the switches have a slightly different checksum; anyone know the process to correct this now? - I like the fact things are breaking I can see what can go wrong. I hate it when things always work....

    Restart VTP on the client switch or Switch between modes on the VTP client (client>trans>client) and it should work - apparently...

    well I think I got it, now to learn why the frig changing it from vtp version 1 to 2 made the MD5 checksum error go away....

    and now I got a different issue why the vlans are showing up as "NULL"

    well I think I figured it out. Basically change the name of a vlan on the 3550 and then saved the config and change the 2950 (cleint) from client to transparent to reset the counter to 0, then saved the config, then reset the switch to transparent, did a vlan database command and force vtp-2 to be used, save it and then changed it back to client and now it seems to be working.

    frig now it works; i'm going to the store to get a case of beer; i'm too sober for this now ;)
