I have two group of 2960 stacked switches connected by trunked (UTP) interface
stack-1 stack-2
SW-1 -------UTP-------- SW-A
SW-2 SW-B
SW-3 SW-C
SW-4 SW-D
I cannot ping stacks by their management IP?
Here is the config of stack-1
stack-1#sh switch

Ok, try these sequence of commands from switch stack 1 ...
conf t
cluster enable
do sh cluster candidate
!!!! Note the MAC address of stack-2
cluster member mac
end
rc 1
!!!! If everything is correct, you should be able to remote into stack-2.

Can you post the output to commands of both stacks:
1. sh interface trunk;
2. sh int vlan 200;

That's why you can't ping the 2nd stack's managmenet IP address. You can't see it in "sh cdp n".
Provide the following commands from the 2nd stack:
1. sh interface vlan 200;
2. sh interface trunk
Maybe interface VLAN 200 is in "shutdown".

Are ports G1/0/48 and G1/0/49 going to the same switch?
01-07-2014 11:52 PM
Yes they are on same switch (stack-1)
here is teh topology
I can reach stack-1 by VLAN200 IP adress
But I cannot reach stack-2
stack-1 stack-2
Backbone------fiber-------SW-1 -------UTP-------- SW-A
SW-2 SW-B
SW-3 SW-C
SW-4 SW-D

On the stack 2, post the output to the following commands:
1. sh interface trunk; and
2. sh interface vlan 200
01-08-2014 12:49 AM
I cannot reach (telnet) stack-2
It is so far to me
I am sure stack-2 config is same as stack-1
is it possible to solve it without going to stack-2
01-08-2014 01:09 AM
Is VLAN 1 on both stack enabled or disabled?
01-08-2014 02:00 AM
Yes
Vlan 1 is enabled
here is config
interface Vlan1
no ip address
!
interface Vlan200

Ok, try these sequence of commands from switch stack 1 ...
conf t

end
