Connect 3548 and 5505 switches

[rusavolk]

Hello,
I would like to interconnect 3548 and 5505 swiches using fast ethernet.

The 5505 is connected to another 5505. There is a trunk created, and they communicate fine (trunk on both end is set to nonegotiate).
Right now there are all on a single VLAN1.


I used crossover cable to connect the 5505 and 3548 but no resolt.

Do i have to create a trunk link between 3548 and 5505 for them to communicate?

I am pretty sure 5505 only supports ISL (but that really depends on the hardware you have as most of the older stuff won't support 802.1q), while the 3548 will support both 802.1q and ISL.

Configure 3548
interface FastEthernet0/24
switchport trunk encapsulation isl
switchport mode trunk
duplex full
speed 100

Configure 5505
set port speed 1/1 100
set port duplex 1/1 full
set trunk 1/1 on isl

You will need to make sure that both switched are in the same VTP domain. If you only have the 2 switches, I would make the 3548 the VTP domain master and the 5505 the VTP domain client.

Here is how to change the VTP information on the 5505 to match the 3548

set vtp domain <domain name>
set vtp mode client




It is what it is!!

Thank you for the reply,
I did just like you wrote, but the switches can not ping each other. (unreachable is disabled).
The VTP version 2 is enabled. The domain name is the same.

I notice that 5505 has some ports set on channels. Maybe it has something to do with it? (Due to my limmited knowledge of CatOS i am sure what channeling is used for... ;-))

 

[computerhighguy]

you can always post your config of both switches. Make sure you include the VTP information.

Hi,

Thank for responding again.

Here the situation.

For some reason the trunk between the 5505 (fast Ethernet port 2/1) and the 3548 does not work…

I have a trunk created between 5505 and another 5505 and works… It is created on port 1/1 (GBIC)
When I use command “show trunk” (on 5505) it show the trunk to port 1/1, the other trunk is not shown, but if I use “show trunk 2/1” it displays the created trunk.

If somebody sees some misconfiguration please post the reply…
:-(

Thank you for your post. YOUR INFORMATION WAS ABSOLUTLY CORRECT!!!

... all i had was a problem with my crossover ethernet cable... which i made myself...
Thanks again
