Distribution Switch Configuration
Subnetting
In our subnetting area, we chose VLSM scheme. Below are the steps we took through:
- The subnets whose size is largest were listed at the top in a sequential order
- The provided network address by supervisor became our starting network address.
- Each VLAN that we have, we are capable of finding octet, subnet size, increment of each subnet and subnet mask
- In the first line of our table, we add the increment for vlan 10 to have a network address for Vlan 11.
- The same process continued for all the subnets
- We were able to get the subnet mask by minusing 1 from the network address of the next subnet.

Spanning tree implementation: I deployed pervlan spanning tree protocol active due to its ability to enhance modularity activities at the Vlan level.
Port security: port security violation shutdown is deployed. Just in case there is a violation of the set parameter, the switch port goes off. No any other activity will take place until the port is actively turned on by the administrator.
Switch allocation: in our design, some interfaces were allocated to trunk mode. Trunk mode allocation enables this ports to carry information for more than one VLAN. On other hand, some ports were allocated to access mode. These are the ports that are directly connected to end nodes as they carry traffic for only one vlan.
Redundancy planning: for the purposes of minimal downtime, we created 2 trunk links between two switches, just in case one fails, another link will pick. Ether-channel technology is also used to improve on the speed of traffic. Here more than one trunk link are bundled together and the bundle appears to be as a single link.
Overall network functionality: we use ping tool.
Redundant link: we disable one link and test the functionality
SW2_Access#conf ter
SW2_Access(config)#inter ra f0/1
SW2_Access(config-if-range)#shut
Here we disabled one link of the network and tested the overall working, everything is working good.
