| Nov 28, 22:40 | AVERAGE | SWITCH ThyssenKrupp - 3 | Interface GigabitEthernet1/0/31: Link down |
| Nov 28, 22:16 | WARNING | AP - ThyssenKrupp - LOJA 83 | High ICMP ping packet loss |
| Nov 28, 22:14 | WARNING | SWITCH - ThyssenKrupp - LOJA 21 | High ICMP ping packet loss |
| Nov 28, 22:13 | WARNING | SWITCH - ThyssenKrupp - LOJA 83 | High ICMP ping packet loss |
| Nov 28, 22:30 | AVERAGE | SWITCH ThyssenKrupp - 4 | Interface GigabitEthernet1/0/6: Link down |
The primary root causes appear to be network link failures. Two critical 'Link down' alerts on SWITCH ThyssenKrupp - 3 (GigabitEthernet1/0/31) and SWITCH ThyssenKrupp - 4 (GigabitEthernet1/0/6) indicate a problem at a higher level of the network infrastructure.
These link failures are likely causing the High ICMP ping packet loss observed on multiple Access Points: AP - ThyssenKrupp - LOJA 83, AP - ThyssenKrupp - LOJA 16, AP - ThyssenKrupp - LOJA 83, AP - CESPU - SALA DOS PROFESSORES.
The affected switches (SWITCH - ThyssenKrupp - LOJA 21, SWITCH - ThyssenKrupp - LOJA 83) are located within the same network segment.
The operational status of several AP interfaces (ath2) on various APs like Auditorium, Stairway, CD - Warehouse, Corridor further confirms the lack of connectivity caused by upstream switch failures.
