Hi
Choose an unused subnet eg.
192.168.5.0 255.255.255.128
You need a L3 interface for this whether on a router or a L3 switch
int fa0/0
ip address 192.168.5.1 255.255.255.128
or
int vlan 2
ip address 192.168.5.1 255.255.255.128
on all your other switches allocate them an unused address from the above subnet and then
1) Create vlan 2
2) Create L3 interface for vlan 2
3) allocate address
4) set default-gateway
switch(config)# vlan 2
switch(config-vlan)# name management
switch(config)# int vlan 2
switch(config-if)# ip address 192.168.5.2 255.255.255.128
switch(config)# default-gateway 192.168.5.1
I have used vlan 2 in this example but you can use vlan 1 on your switches if you want, Cisco just recommend changing the management vlan from vlan 1.
I have assumed your switches are L2 switches only, so they will only be able to have one active L3 interface ie. vlan 1 or vlan 2, your choice.

Hi,
We have one L3 switch and other 49 are L2 switch.
When I try the below said command,its shows error
Bad mask /25 for address 192.168.5.2
switch(config)# int vlan 2
switch(config-if)# ip address 192.168.5.2 255.255.255.128

Did you enable the below commands on L3 device..
ip subnet-zero, ip classless.
Try both, it might fix it.
