no Need.Here is the procedure

no Need.

Here is the procedure:

Tips to Add a Switch as a Slave to the Stack

To add a switch, as a slave, to a stack, complete these steps:

Note: Make sure the switch that you add into the stack has the same IOS version as the switches in the stack. Refer to Catalyst 3750 Software Upgrade in a Stack Configuration with Use of the Command-Line Interface to upgrade the IOS in a catalyst 3750 switch.

  1. Change the switch priority of the switch to be added to "1".

    switch stack-member-number priority new-priority-value

    Note: This step is optional, but it will make sure that the switch has fewer chances to become a stackmaster in the future.

  2. Power off the switch that is to be added.

  3. Make sure that the stack is fully connected so that, when you connect the new switch, the stack will be at least in half connectivity and does not partition.

  4. Connect the new switch to the stack with the StackWise ports.

  5. Power on the newly added switch.

  6. After the new switch comes up, issue the command show switch to verify stack membership.

ahh.so for example my switch

ahh.so for example my switch c2960s old has ip add of 192.168.1.1 this will be my master then no need to configure the 192.168.1.1 to my new  c2960s switch that will be my slave. so it will be automatically determine the my new switch ip address will be 192.168.1.1. right? in my understanding.

Cisco Employee

yes no need to configure the

yes no need to configure the second switch with the same ip address.

The config would be pushed directly from Master to slave.

If it helps your understanding, when you stack switches (or VSS cluster), you basically have one "logical" device to configure.  Ports on member devices appear much like line card ports do on chassis models.  There's only one configuration for non-port stuff, e.g. one hostname, one VLAN interface, etc.

so in my case i will just

so in my case i will just configure the stack configuration on my old switch and the new one no need  to configure. i will just put the stack cable for the new one and will be automatically be the slave one and the configuration of old one will be automatically get by the slave switch?

Yes and no.

(NB: I've worked much with 3750 stacks, but not 2960 stacks, although I think they are much alike - i.e. what I'm about to write might be incorrect for 2960 switches.)

I believe all the configuration of the to-be-added stack member will be lost.  The newly stack member will "share" the stack's global configuration but ports may need to be reconfigured.

I also believe, it's possible to "pre-configure" the to-be-added stack member port settings on the active stack.

By default, newly added stack members are "numbered" with the next available stack number, but if they are "recognized" they will be numbered as configured on the active stack.

Full details are found in the IOS reference manual and guide manual for you IOS version.

thanks for the information

thanks for the information insharie and joseph doherty. I hope i can manage this on my switch.

hello again, i already try to

hello again, i already try to set my 2 c2960s switch using stack for my redundancy, the older 1 already have configured and configure  the priority of old 1 to determine that is the master 1  and for the new 1 i just left no configuration so that it will be the member or slave one, but upon doing "show switch version" and "show switch neighbor" the result for "show switch version" both master and for "show switch neighbor" the result is none.

You did or did not physically

You did or did not physically stack them before doing the show commands?

New Member

we are already did the

we are already did the physically stack before i do the show commands. after doing the physically stack we turn on first the old switch to be the master before turn on the new switch for slave or member.
