300-115 - Implementing Cisco IP Switched Networks - SWITCH

The core layer separates the control plane from the data plane, with routing updates on the route processor and neighbor and IP routing tables guiding forwarding in the switching fabric.

Map Cisco switch models to network layers, aligning access, distribution, and core roles for business sizes, and explore layer two and layer three designs with spanning tree considerations.

Explore multilayer operation that blends layer 2 and layer 3 forwarding, using a layer 2 table and a layer 3 forwarding table, with mac addresses and cams guiding exit interfaces.

Explore three Cisco switching methods—process switching, fast switching with route caching, and topology-based Cisco express forwarding—and how hardware forwarding delivers fastest performance.

Explore how SDM templates control switch resource allocation and view the current and default templates. See how the desktop default template affects interfaces, MAC addresses, multicast groups, and routes.

Identify and change the SDM template to support IPv6, reboot to activate, and verify IPv6 unicast routing, while checking TEAC HIM utilization to justify the change.

Explore the differences between Cisco discovery protocol and the link layer discovery protocol, and learn how to enable it on Cisco devices.

Explore LLDP, a standards-based link-layer discovery protocol that unidirectionally advertises device identity and capabilities using TAAB format, contrasting with Cisco's CDP.

Explore how to use the show LDP neighbors command to discover and inspect neighbor devices, similar to CTP, and view chassis IDs, system names, software, and media details.

Explore power over ethernet (PoE) and how it delivers data and power over a single cable to devices like access points and IP phones.

Review the plans and trucks, recap what you learned in cc a, and franks, and add extra topics for the cc empey exam.

Configure the voice vlan on an access port to place IP phones in vlan 110 while data traffic remains on vlan 10, enabling prioritized voice over IP traffic.

Demonstrate VLANs on a switch by placing two hosts in separate VLANs, showing initial ping within the same subnet, then layer 2 isolation requiring routing for inter-VLAN communication.

Explore how the VTP server creates VLANs and pushes them to switches in client mode over trunk links, and compare server, client, and transparent modes.

Understand VTP versions: default version 1, version 2 in transparent mode, and version 3 with extended private VLAN support. Use show VTB status and VTB version commands to configure.

Explore VTP revision numbers, how a higher revision on a client can overwrite the server and create orphan lands, and apply transparent mode with local lands and consistent passwords.

Set up dhcp on a router to provide ip address configurations to hosts on an interface, illustrating automated network configuration concepts.

Learn how a layer 3 switch uses an IP helper address on the client interface to forward DHCP requests to a server. It converts broadcasts to unicast and relays replies.

Explore configuring DHCP options like 53, 16, 70, and 150 to direct clients to specific servers, using a DHCP pool to assign these options and server addresses.

Demonstrates turning a Cisco router into a DHCP server by creating a pool named my_pool, defining the network and gateway, excluding the gateway address, and verifying a host lease.

Explore how enterprises switch from IP version 4 to IP version 6 and implement DHCPv6 in stateless and stateful mode to provide IP version 6 configuration.

Learn how stateless DHCPv6 provides DNS and domain information without IPv6 addresses, and how router advertisements and DHCPv6 relay connect clients to servers across broadcast domains.
