Bandwidth restricting/limiting/shaping with Sub-Interfaces in Cisco IOS The following port describes on what is bandwidth limiting and how we can configure them with Cisco routers which are configured with Sub-Interfaces. Scenario: Switch0 configure with 3 vlans Router0 configured with 3 sub-interfaces with correct vlan tags. switch <--> router configured as trunk port. Configuration in router:  Creating access lists that matches the LAN networks. access-list 101 permit ip any 192.168.10.0 0.0.0.255 access-list 102 permit ip any 192.168.20.0 0.0.0.255 access-list 103 permit ip any 192.168.30.0 0.0.0.255   Creating class-maps that maps to the LAN networks:   class-map match-all vlan10  match access-group 101 class-map match-all vlan20  match access-group 102 class-map match-all vlan30  match access-group 103 Note: here vlan10, vlan20, vlan30 are the names of the class-maps that we have cre...

Packet from Host --> server O - Offer: The server offers a Unique IP address to the host in response to the Broadcast. Packet from server --> Host R - Request: The host requests for the IP address offered by the server. Packet from Host --> server A - Acknowledgement: The server sends a acknowledgement packet along with details of IP address, Subnet mask, gateway, Dns server1 and Dns server 2.
