The switch reboots and:

After searching online i have no seeing nothing about disable the feature of the stack so i configure the priority for the "switch 1" to 15 and configure it the switches 2, 3 and 4 to no provision, although this switches don´t exist:
SW_ACCESS(config)#switch 1 priority 15
Changing the Switch Priority of Switch Number 1 to 15
Do you want to continue?[confirm]
New Priority has been set successfully

With this new configuration the switch has rebooted again.Why on a standalone switch the stack is rebooting my system?Is it any feature to disable the stack?

Cisco Switching/Routing :: Stack Mac Persistent Timer Lacp Port Channels C3750
Sep 27, 2012I am having an issue on a Cisco 3750 stack where when the stack master is rebooted, all my lacp port-channels drop and then come back up again. After doing some investigation It seems that it is happening because of lacp using the stack master mac-address as part of the system-id, so when the stack master reboots, the stack mac changes. I see that there is the command: stack-mac persistent timer 0
There is this warning about using this command:
When you configure this feature, a warning message displays the consequences of your configuration. You should use this feature cautiously. Using the old master MAC address elsewhere in the domain could result in lost traffic.
My question are:
Are there any other consequences to using this command (apart from moving the switch/mac to another location in the network)It mentions 'If the entire switch stack reloads, it acquires the MAC address of the master as the stack MAC address' Is this still the case if you have the stack-mac persistent timer to 0? Does using channel-group mode on for the port-channels still use the same mechanism of having a system-id? (Will the channels flap using 'mode on' when rebooting the stack master.

1. Are there any traps gotchas?
2. What about IOS versions - aren't they different for V2 switches
3. Are the stack ports and stack cables same for both WS-C3750V2-24PS-S and WS-C3750-24PS-S
4. What is the main reason for bringing out the V2 switches. What features do they have extra?

Cisco Switching/Routing :: 2960G Configuring Ether-channel On Stack-wise Stack
Sep 24, 2012A site that i am responsible for has the following equipment installed:
2 x 3750G Switches configured as a stack using Stackwise - Collapsed Core/Distribution Layer
5 x 2960G Switches as Access Layer switches
WAN connections into the Core/Distribution Layer are all Gigabit Ethernet over Fibre.This is a dedicated CCTV Network with 50 Cameras all streaming video into the Core (decoders connected to access switches)Each 2960G has 2 links to the Core/Distribution 3750G Switches, 1 to each switch - Gigabit.I'm running rapid-pvst on all switches, so spanning tree is blocking one of the ports and effectively halving the 2 gig bandwidth. Next year our customer is going to add in a further 50 - 60 cameras.After monitoring the current loading on the ports in use, we have suggested to the customer that the 2 connections to each should be Ether-channeled together. [code]
First interface takes commands no problem, keep getting the message that etherchannel cannot be configured across different switches in a stack when i try to put the second interface commands on.
