I want to upgraded my Cisco 3750 switches. The current IOS is flash:c3750-ipbase-mz.122-35.SE5/c3750-ipbase-mz.122-35.SE5.bin
What is the latest IOS version I can use for these switches? This versions is the latest on the cisco download site. Is is ok to upgrade to this version or do I do I need to upgrade starting with a lower version progressing upward??? Thanks
We just bought 3 x new 3750x-48Ps to replace our old stack 3x 3750-48s.
What is the best way to migrate the 3 x old stacks ( consist of 2 x 48 ports + 1 x 24ports) to
a new stack of 3 x 48 ports switches.
This is what I would normally do if I need to replace a stack member and, as much as possible, LESS configuration.
In your case, let us say I've got three switches in a stack. The replacement switches are running the same IOS as the current switches. Switch #1 is the stack master.
1. Remove the configuration of stack #3 and add the new switch as stack member 3.
config t no switch 3 provisioning [BLAH] switch 3 provisioning [BLAH] end
2. Power down existing switch #3 and remove both stacking cable from switch #3.
3. DO NOT POWER UP the new switch.
4. Cable up the new switch #3.
NOTE: Somewhere here, you can pre-configure the ports to the new switch #3.
5. Power up the new switch #3 and observe the stack joining process.
If everything goes well, repeat the process from 1 to 5 for Switch #2 and Switch #1.
Thank you for your valuable suggestion.
However since the 3 switches are in the production and the rack are quite full and have
an hour windows to replace them.
I was thinking of doing a TFTP config of the old stack and upload the config to the new
stack setup in the test bench and when the time come shutdown & unmounted the old stack and replaced with the new ones.
Would this approach work ?
The stacks are a bit different.
old one : 24 ports Master + 48 + 48 ports
new one : 48 ports master + 48 + 48 ports
when i do tftp old config to the new stack , only the first 24 ports config come across ie a bit odd .
have to manually copy the rest of 2 x 48 ports config across!!!
This one is updated as the latest IOS in Cisco Site
