Level 1

I am configuring 4 x Cisco 2960x - 24PS switches for voice . What details will I need before proceeding with it ?

These 4 switches will be connected to 3560 Cisco Catalyst switch. There are about approx 60 users .

What is the best way to  do this ?

Hi
make sure to take the global config off the 3560s , ssh , acls/AAA that are required etc they would already be in place and can be transferred to the 29s as its global config for the network

but for your access an uplink ports to the 3560 below will get you going , pc into back of the phone , phone into the switchport, turn cdp on , small bit of auto qos to make sure the voice packets are marked , 3560 should be doing something similar

replace the xxxs with your vlan ids and allow them on the trunk link , create the vlans at layer 2

Access ports

interface GigabitEthernetx/x
description Voice and Data
switchport access vlan xxxxxxxxxxxxxxxx
switchport mode access
switchport voice vlan xxxxxxxxxxxx
auto qos trust
spanning-tree portfast edge
spanning-tree bpduguard enable


uplink

interface GigabitEthernetxxxx
description uplink to xxxxx
switchport trunk allowed vlan xxxxxxxxxxxxx
switchport mode trunk
auto qos trust dscp

cdp run


ip default-gateway x.x.x.x

Hi
conf t mode

switch 1 pri 15
then check it again , you may have to set this too
switch 2 pri 14

15 is highest priority an wins as master , 1 is lowest

You may need to reboot stack to force it though due to the preference rules

The election rules used by FlexStack in choosing a master are applied in this order:

1. Switch that is the current master

2. Switch with higher priority

3. Switch that has configuration file

4. Switch with highest uptime

5. Switch with lowest MAC address block

Thanks Mark!

I have configured switch 1 among the 4x 2960 switches.

The requirement now is to stack them. 

My question is what is the best way to add the 3 switches ? At this time, all the 3 switches are racked and powered on.

No stack cables connected yet. 

My plan was to connect the stack cables then make Sw1 as stack master. 

Hi
Power them down all down , cable them , make sure its a proper ring , bottom switch is linked back to the top switch, power them back up at the same time , its cleaner than trying to do it live

make sure the switches are running same software so each switch has same feature set in the stack

Good DOC to follow short with examples config and guide on stacking 29s

Thank you! I currently have stacked 3 switches ( no stack module for 4th) 

Cables connected correctly.

Now, maybe the field tech kept the switches powered on or something, it has resulted in :

 

H/W Current
Switch# Role Mac Address Priority Version State
----------------------------------------------------------
1 Member x.x.x.x 1   4 Ready
*2 Master  x.x.x.x 15 4 Ready
3 Member x.x.x.x  1  4 Ready

 

How can I make the Master switch as Switch# 1 without affecting change in config?

 

Hi
conf t mode

switch 1 pri 15
then check it again , you may have to set this too
switch 2 pri 14

15 is highest priority an wins as master , 1 is lowest

Thanks for your help! it worked.

I reloaded the switch and it corrected the Stack Master as sw#1

 

no problem , good stuff getting it fixed
