Number of channel-groups in use: 1 Number of aggregators: 1 S1# show etherchannel summary Flags: D - down P - in port-channel I - stand-alone s - suspended H - Hot-standby (LACP only) R - Layer3 S - Layer2 U - in use f - failed to allocate aggregator u - unsuitable for bundling w - waiting to be aggregated d - default port This command displays the type of EtherChannel, the ports utilized, and port states. Issue the show etherchannel summary command to verify that EtherChannel is working on both switches. S3(config)# interface port-channel 1 S3(config-if)# switchport mode trunk Step 2: Verify Port Channel 1 status.ДЄ. S1(config)# interface port-channel 1 S1(config-if)# switchport mode trunkДЄnswer Note: Packet Tracer 6.0.1 does not grade the switchport mode trunk command in port-channel interfaces. Add this configuration to both switches.ДЄnswer Note: Packet Tracer 6.0.1 does not grade the switchport mode trunk command in port-channel interfaces. Configure the logical interface to become a trunk by first entering the interface port-channel number command and then the switchport mode trunk command. S3(config)# interface range f0/21 - 22 S3(config-if-range)# shutdown S3(config-if-range)# channel-group 1 mode desirable S3(config-if-range)# no shutdownД¬. S1(config)# interface range f0/21 вЂ“ 22 S1(config-if-range)# shutdown S1(config-if-range)# channel-group 1 mode desirable S1(config-if-range)# no shutdown The mode desirable option enables the switch to actively negotiate to form a PAgP link. On both switches, add ports F0/21 and F0/22 to Port Channel 1 with the channel-group 1 mode desirable command. Port Mode Encapsulation Status Native vlan F0/21 on 802.1q trunking 1 F0/22 on 802.1q trunking 1 G0/1 on 802.1q trunking 1 G0/2 on 802.1q trunking 1Д«. Use the show interfaces trunk command to ensure that you have an active trunk link for those two links. The first EtherChannel created for this activity aggregates ports F0/22 and F0/21 between S1 and S3. The ports and port channels can be re-enabled after EtherChannel is configured. Otherwise, the EtherChannel Misconfig Guard may place these ports into err-disabled state. Note: When configuring EtherChannels, it is recommended to shut down the physical ports being grouped on both devices before configuring them into channel groups. S3(config)# interface range f0/21 - 24 S3(config-if-range)# switchport mode trunk S3(config-if-range)# end S2(config)# interface range g0/1 - 2 S2(config-if-range)# switchport mode trunk S2(config-if-range)# interface range f0/23 - 24 S2(config-if-range)# switchport mode trunk S2(config-if-range)# end S1(config)# interface range g0/1 - 2 S1(config-if-range)# switchport mode trunk S1(config-if-range)# interface range f0/21 - 22 S1(config-if-range)# switchport mode trunk S1(config-if-range)# end The default mode on a 2960 switch is dynamic auto. Note: If the ports are configured with dynamic auto mode, and you do not set the mode of the ports to trunk, the links do not form trunks and remain access ports. Configure all required ports as trunks, depending on the connections between devices. Switch(config)# hostname S1 Switch(config)# hostname S2 Switch(config)# hostname S3Д«. Assign each switch a hostname according to the topology diagram. Part 1: Configure Basic Switch Settings Step 1: Configure basic switch parameters.ДЄ. In this lab, you will configure Port Aggregation Protocol (PAgP), a Cisco EtherChannel protocol, and Link Aggregation Control Protocol (LACP), an IEEE 802.3ad open standard version of EtherChannel. EtherChannel allows up to eight redundant links to be bundled together into one logical link. However, using only one link utilizes only half of the available bandwidth. Usually, only one of these links could be used otherwise, a bridging loop might occur. There are redundant uplinks between the switches. Part 4: Configure a Redundant EtherChannel Link Background Part 3: Configure an 802.3ad LACP EtherChannel Part 2: Configure an EtherChannel with Cisco PAgP 4.2.1.3 Packet Tracer вЂ“ Configuring EtherChannel Objectives
