Hi Ricky,
You probably just need to get all the right VLANs trunked between both
switches. I will assume you have more than one vlan, but you can confirm
this by using the "show vlan" command.
A standard configuration with more than one VLAN and ports for any given
VLAN on more than one switch would look like this:
Switch1
|
|
trunk
|
|
Switch2
Assume port g1 is used on Switch1 to link to port g2 on Switch2.
Assume the two VLANs in question are 100 and 200.
Assume you need ports from both VLANs on both switches.
On a Dell switch, you would do the following:
Switch1# conf
Switch1 (config)# int eth g1
Switch1 (config-if)# switchport mode trunk
Switch1 (config-if)# switchport trunk allowed vlan add 100
Switch1 (config-if)# switchport trunk allowed vlan add 200
Switch1 (config-if)# Ctrl-Z
Switch1# copy run start
*note - you could just use,
switchport trunk allowed vlan add all
If you like, also add a description.
Switch2# conf
Switch2 (config)# int eth g2
Switch2 (config-if)# switchport mode trunk
Switch2 (config-if)# switchport trunk allowed vlan add 100
Switch2 (config-if)# switchport trunk allowed vlan add 200
Switch2 (config-if)# Ctrl-Z
Switch2# copy run start
That would allow both VLANs to pass over the one cable (the trunk). It
will take about 45 seconds for the link to come up due to Spanning Tree
calculations (that is the protocol for avoiding loops in your network).
Feel free to contact me off-list of you have additional questions.

Hi! I have a problem that I was hoping I could get some advice on. In
particular, where to start looking...
I inherited a Rocks Cluster which I am trying to make semi-usable. There
are 31 nodes in the cluster, so in order to create the cluster network,
two Dell switches are used -- a PowerConnect 5224 and a PowerConnect
5324. The head node and most of the computer nodes are plugged into the
5224, and the rest are plugged into the 5324 which then is plugged into
the 5224. The problem that I'm having is that the clients on the 5324
cannot be PXE booted properly. If I plug them into the 5224, let them
boot and install, and then plug them back into the 5324, they work
correctly, until the next time I need them to reboot (to add a package,
or something).
I assume there is some kind of packet that is not being properly
forwarded by the 5324 (or not being allowed by the 5224). What I would
like is to convince the two switches that they are really one big(ger)
switch, so they don't block anything from going around. Unfortunately, I
really don't know much about networking beyond the basics -- in
particular, I don't know the terminology. Looking at the configurations
of the switches, I see things like "spanning-tree", "bridging",
"trunks", etc.
What should I be looking at? I tried to Google various things, but I'm
not convinced I even know where to start -- at least, nothing I've found
seems to address my question, or at least make sense to me.
Thanks for any pointers, Ricky
