Complete and correct the EtherChannel configuration between switches sw101, sw102, sw110 according to these requirements:

1. At the end of task, all EtherChannels between switches sw101, sw102, sw110 must be up and operational including all their physical member links.

2. Do not create new Port-Channel interfaces, reuse those that already exist on the switches.

3. When resolving existing issues, do not change the preconfigured negotiation protocol (if any). 4. On EtherChannels that use a negotiation protocol, tune its mode of operation for the shortest link bundling time possible.

Configure Spanning Tree Protocol on switches sw101, sw102, sw110 according to these requirements:

1. The STP root for VLAN 2000 must be sw101

2. The STP root for VLAN 2001 must be sw102

3. The roots must be elected based on bridge priority

4. On the three switches, have STP perform cost calculations in 32-bit arithmetic

5. On the three switches, use the Rapid STP version and ensure that it can achieve rapid

convergence on all interconnections between the switches.

6. On sw110, prevent all current and future access mode interface from being affected by the Proposal/Agreement process.

Solution

SW101:

sw101(config)#interface range gigabitEthernet 1/2-3

sw101(config-if-range)#Channel-group 1 mode on

sw101(config)# interface range gigabitEthernet 2/0-3

sw101(config-if-range)#channel-group 1 mode passive

sw101(config)#spanning-tree mode rapid-pvst

sw101(config)#spanning-tree vlan 2000 priority 0

sw101(config)#spanning-tree pathcost method long

SW102:

sw102(config)#interface range gigabitEthernet 1/2-3

sw102(config-if-range)#channel-group 2 mode active

sw102(config)#Spanning-tree mode rapid-pvst

sw102(config)#spanning-tree vlan 2001 priority 0

sw102(config)#spanning-tree pathcost method long

SW110:

sw110(config)#spanning-tree mode rapid-pvst

sw110(config)#spanning-tree portfast edge default

sw110(config)#spanning-tree pathcost method long
