Ali,

Your design is correct and its Ok as per the guidelines. By-default vlan is the Managemnt vlan on l2 switches. Its is always advisable to use a different vlan other than Vlan1 as the managemnt vlan.

As you have used a different vlans on each switch as the management vlan, you should be fine with it. To have consistency on the manageing the switch IP's I would suggest you to have the same dedicated vlan for management across all your switch. Like using Vlan 51 and the same range if IP across all the L2 switches for managemnt. this will make you managing the switches easily across the network and easy to remember IP addresses.

If you are using a diffrent vlan on each switch as management vlan, make sure that your 4507 core switch is routing for all vlans. otherwise there will be connectivity issues in the network.

Hi Ali,

What I see is that you have different vlans created on your access switch but subnet address is same across all which I don't think is a proper design. Another thing which I notice is that your l3 interfaces on your core are on dfferent subnet as what you have on your access which again is a wrong design.

Like you vlan 50 on core is 100.4.50.2/24 but you have configured vlan 50 on your access as ip address 100.4.1.4 which is wrong and the right design should be something likr 100.4.50.2/24 on your core and ip address 100.4.50.x/24 on your access siwtches for management.

Also I see on youe CORE you have same vlans 50 , 51 and 52 but with different subents which is fine.

I will recommed you to have same management vlan across all access switches and your core config is fine where you have l3 interfaces with different subnet.

You can keep 50 or whatever vlan you want for management on all your access switch but whatever vlan you decide for management vlan make sure the ip address which you assign on access switch should be in same subnet as you configure on core.
