Lab # 2
VLAN & VTP Objective To understand VLAN & VTP operations in switched environment.
Verification Of Spanning Tree Operation in PVST Mode Since, Cisco catalyst switches are running in PVST mode, by-default. It means that each spanning tree instance is used for each VLAN. The Root Switch can be different for every VLAN.
Verifying Commands Switch# show spanning-tree vlan 1 Switch# show spanning-tree vlan 5

Lab # 4
Tuning Spanning Tree Protocol (Port-Fast, Uplink-Fast) Objective Tune the spanning tree protocol for enhancing network performance and minimizing the network downtime by enabling port-fast & uplink-fast features.
i. Port Fast Port Fast is used to bypass the STP Timers for connected PCs and Servers.
Protecting Spanning Tree Protocol Topology (BPDU Guard, Root-Guard) Objective Tune the spanning tree protocol for enhancing network performance and minimizing the network downtime by enabling BPDU Guard & Root Guard features.
Ether Channel Objective Ether Channel allows to specify the multiple Ethernet ports of the same type as a single virtual link. Lab Objective : 1. Enable Ether-Channel with no protocol on Cisco catalyst switches. 2. Enable Ether-Channel (PAgP) on Cisco catalyst switches. 3. Enable Ether-Channel (LACP) on Cisco catalyst switches.
