  The operations team started configuring network devices for a new site. Complete the configurations to achieve these goals:

  1.

  The trunk between SW10 and SW30 is not operational. Troubleshoot the issue and ensure C2 can ping PC1 (10.10.100.10) across the link.

  2.

  Configure SW10 interface E0/0 for aggressive unidirectional link detection.

  3.

  The LACP port-channel between SW10 and SW20 is not operational. Troubleshoot the issue and ensure that PC2 can ping PC3 (10.10.100.30) across the port-channel. Note: No access is provided to SW20 or SW30. Resolve these issues by making changes only to SW10. Traffic on all trunks should be restricted to only active VLANs. Topology
