TNE10006/TNE60006 Lab SU9a Networks and Switching Background / Scenario Link aggregation allows the creation of logical links that are comprised of two or more physical links. This provides increased throughput beyond using only one physical link. Link aggregation also provides redundancy if one of the links fails. In this lab, you will configure EtherChannel (a form of link aggregation used in switched networks) using both the Port Aggregation Protocol (PAgP) and the Link Aggregation Control Protocol (LACP). Note: PAgP is a Cisco-proprietary protocol that you can only run on Cisco switches and on switches that are licensed vendors to support PAgP. LACP is a link aggregation protocol that is defined by IEEE 802.3ad, and it is not associated with any specific vendor. LACP allows Cisco switches to manage Ethernet channels between switches that conform to the 802.3ad protocol. You can configure up to 16 ports to form a channel. Eight of the ports are in active mode and the other eight are in standby mode. When any of the active ports fail, a standby port becomes active. Standby mode works only for LACP, not for PAgP. Note: Make sure that the switches have been erased and have no startup configurations. If you are unsure, contact your instructor. Required Resources · 3 Switches · 3 Virtual PCs (if on-campus) . Ethernet cables as shown in the topology Part 1: Configure Basic Switch Settings In Part 1, you will set up the network topology and configure basic settings, such as the interface IP addresses, device access, and passwords. Step 1: Initialize and reload the switches. Step 2: Validate the network topology. Validate network devices are interconnected as shown in the topology diagram and cabled as necessary. PCs are included in the topology diagram for your reference only. PCs will not be available when working online. Step 3: Initialize and reload the switches. Step 4: Configure basic settings for each switch. a. Disable DNS lookup. b. Configure the device name as displayed in the topology. c. Create a MOTD banner warning users that unauthorized access is prohibited. d. Configure logging synchronous to prevent console message from interrupting command entry. e. Shut down all switch ports except the ports connected to PCs. f. Configure VLAN numbers and names as per the configuration table g. Configure
