Re: Catalyst 3750x - 5 switches stack config help

Hello there, no special configuration required for stacking switches together. Just ensure all switches have the same IOS and that the stacking cables are plugged in the stack-ports correctly.

When you power the whole stack up, the switches will identify other members in the stack-ring and election will take place on who becomes the master.

When successful boot has completed you will find that all switches appear as one logical switch I.e. have formed into a stack.

Hope this helps

No, you don't need all 5 switches to configure for them (as Leo already explained, you can pre-provision).

The ports on each switch are prefixed with the switch's logical number in the stack.

If you correctly pre-provision, as other stack units come on-line they will use the configuration for their ports.

PS:

If you've never worked with a 3750 stack, but if you have worked on a Cisco chassis switch, it's very similar.  Stack members are configured much like a chassis's line cards.  Global commands apply to the whole logical stack.

Just 5 VLANs, Two ports for uplink as an EtherChannel , Access ports.

Questions I have are ,  when I am configuring , do I have to have all 5 Switches powered up  ? Also , do I have to assign ports , tag them seperate on each switch i.e . Fa1/0/23 , Fa 5/0/23 etc.. Or can I just configure 1/0/23 and then power the rest up to propogate the config and ports assigned ?

You can pre-provision the entire stack from the master.

You just do this:

config t

switch 2 prov

end

Once you do this, you can start entering interface configurations for the 2nd switch.

Thanks.

So I can bring one switch at a time and configure that and then do interface configs for each switch ?

No, you can pre-configure the entire stack from the stack master.

You can do the following:

config t

switch 2 prov

switch 3 prov

switch 4 prov

switch 5 prov

end

And then you can configure the switch port interfaces.

Yeah with this, just be sure to increase the priority just in case so you don't lose your config, LOL.

Also to configure the switches the correct numbers when they become part of the stack.

Re:Catalyst 3750x - 5 switches stack config help

I would recommend preconfiguring as much as you can by using the above commands. Just connect the Master first boot it up, then connect the 2nd switch with cables then power up the second switch and make sure everything is operational. And repeat the process for however many switches you have
