Could anyone help me. Appreciate your inputs in advance.
I have done several tries doing these commands but still stacking feature exist.
switch(config)# switch 2 renumber 1
switch(config)# no switch 2 provision
also, switch# wr erase
Unplug the cable?
What in particular are you trying to get rid of?
You will need to do the following:
3750(config)# no switch 2 provision ws-c3750-48ts
3750# write memory
That way if the switch was provisioned in a stack configuration it should remove all of the stack provision infromation that was configured.
If you unplug the cable on the 3750, you loose half of the back plane speed. Even in a single switch environment, a single cable looped back to the same switch completes the ring and doubles the backplane speed. Very strange how it works.
I get this prompt when trying to set GLBP in 3750
"%GLBP is not supported by the switch stack"
trying if GLBP will work after disabling totally the stack feature
your suggestion still gives the same result. Stacking is still there.
"Switch 1 booting as Master"
I believe that it is not possible to turn off the stacking feature in a 3750. If the switch is stand alone then it will always boot as master during the boot process.
i'm a bit curius about you said. I've tried to loopback to it's 2nd stack port in the same switch, but how would I know that backplane speed doubles?
I might have overlook inthe cisco docs/reference site
but what I've read states only these:
After adding or removing stack members, make sure that the switch stack is operating at full bandwidth (32 Gbps). Press the Mode button on a stack member until the Stack mode LED is on. The last two port LEDs on all switches in the stack should be green. Depending on the switch model, the last two ports are either 10/100/1000 ports or small form-factor pluggable (SFP) module ports. If, on any of the switches, one or both of the last two port LEDs are not green, the stack is not operating at full bandwidth.
I dont think your find GLBP is supported on the 3750 unless your have a 3750 Metro switch running 12.2(58). Your have to use VRRP or HSRP.
To see the speed of you backplane type "show switch stack-ring speed" (dependent on code again.
1 x stack cable between 2 switches = 16Gb
2 x stack cable between 2 switches = 32Gb
It's basically a ring (16 one way and 16 the other )
Just make sure you have done the screws up tight, otherwise you might have problems.
I would have to agree with Mark. I don't think it can be turned off. I think even 3560's go through the process, but it never works because there is no stacking port.
Then how come Cisco includes this GLBP features in these models if at the end you can't use it due to stacking feature??? The 3750 image i'm using in fact supports GLBP features but then, it's useless because stacking feature doesn't support it. Terrible!
Actually, what you are seeing is quite common. IOS was meant to be the same OS for every networking device. Now because there are so many versions, that really isn't the case, but the concept was there. As a part of the concept, if you were to load the same OS for a router as you would a switch then they would have the same commands, only some commands wouldn't work because the hardware would not support them. This is true with any IOS device to certain degrees.
Understood Jared. Thank you.
For some reason, could also be part of a product market promotion...
I first ran into this when I noticed a bunch of commands on a wireless bridge running IOS. I thought "why in the world would the commands even be here on this device." Well, a Cisco SE explained it to me and it made total sense. Now on the reverse of this, when new hardware is released, say a specific blade for a modular switch like the 4500 or 6500, you have to have the IOS updated so it recognizes the hardware, otherwise it won't know how to handle the hardware. So when you see features that shouldn't be there or don't work, remember they gotta have the right hardware!
