Good Day,

 

Guys please advice on steps in order to configure layer 2 networks . For example 

1 - VTP Configs (in case if not nexus)

2 - Configurations of Vlans

3 - STP configuration with loadbalancing

4 - Port Security on edge switches. 

 

Guys pls add your inputs....

 

Thanks & Regards,

Hi

My recommendations are: 

 

1 - VTP Configs (in case if not nexus)

     All the switches must be configured as Transparent, Is recommendable a good knowledge about VTP to be deployed because any human error could create critical problems on the network, other solution is to use VTP version 3 but you must see if it is supported on your switch models. 

2 - Configurations of Vlans

      Create VLAN manually and with real descriptions and on Capital Letters to be visible. 

3 - STP configuration with loadbalancing

      Usually I dont suggest modify the STP parameters to manipulate the traffic but you can use same priority on the designated ports from the root switch toward the non root switches or you can modify the STP cost under the interfaces under the root ports toward the root switch. 

4 - Port Security on edge switches. 

     Configure a maximum amount of mac addresses, I think it could be 2 or 3 for users and meeting rooms at least 5, also configure the port security aging time to remove the inactive mac addresses: switchport port-security aging time <time in minutes> type inactivity. You can set up the port security as sticky and violation shutdown. 

 

 

Hope it is useful
