Slack alerts are in preview mode. A production connection needs a server-side Slack webhook so its secret is never exposed in the browser.

This hosted page demonstrates discovery safely. A browser cannot perform raw ARP or scan nearby devices; real scans require a local companion running on a network you own or are authorized to test. Vulnerability checks are non-destructive configuration reviews.

LACP and PAgP EtherChannel project

Build two trunk EtherChannels across three Cisco switches. Use LACP on the left bundle and PAgP on the right, then verify that VLAN traffic survives a failed member link.

SW32960
VLAN 10
PC-B192.168.10.20

Protocol rule: LACP uses active/passive; PAgP uses desirable/auto. At least one LACP side must be active and at least one PAgP side must be desirable. Do not mix the two protocols inside one bundle.

Your objectives

  1. Place three 2960 switches and two PCs, then cable every link shown above.
  2. Create VLANs 10 and 20 on all three switches.
  3. Build LACP Port-channel 1 between SW1 and SW2.
  4. Build PAgP Port-channel 2 between SW2 and SW3.
  5. Configure both Port-channels as trunks allowing VLANs 10 and 20.
  6. Put both PC ports in VLAN 10 and verify end-to-end connectivity.

Proof checklist

  1. show etherchannel summary displays Po1(SU) and Po2(SU) where applicable.
  2. Each bundled member shows the (P) flag.
  3. show interfaces trunk lists Po1 and Po2, not four separate trunks.
  4. PC-A can ping 192.168.10.20.
  5. Shutting one member of each bundle keeps the ping working.
  6. show lacp neighbor and show pagp neighbor identify the adjacent switch.

Try the project first. The solution is here for checking, not speed-running the lab like a tiny network goblin.

Verification and failure test

show etherchannel summary
show interfaces trunk
show lacp neighbor
show pagp neighbor

! Test one failed LACP member on SW1
configure terminal
interface fa0/1
 shutdown
end
show etherchannel summary

! Restore it after the ping test
configure terminal
interface fa0/1
 no shutdown
end
