Este é um bug na versão do IOS que você está usando e está arquivado em CSCtq86186. Execute um show interface counter error
e veja o outDiscards
parece lá. Isso me faz coçar a cabeça.
Eu sempre tive a impressão de que a queda na produção da Total era um contador que sobe até ser redefinido (ou talvez cerca de 4 bilhões).
No entanto, isso parece indicar o contrário ou algo está errado:
ny-swstack01#show int GigabitEthernet2/0/25 | inc Total output drops
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 14456
ny-swstack01#show int GigabitEthernet2/0/25 | inc Total output drops
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 3614
ny-swstack01#show int GigabitEthernet2/0/25 | inc Total output drops
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 3614
ny-swstack01#show int GigabitEthernet2/0/25 | inc Total output drops
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 3614
ny-swstack01#show int GigabitEthernet2/0/25 | inc Total output drops
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 3614
ny-swstack01#show int GigabitEthernet2/0/25 | inc Total output drops
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 3614
ny-swstack01#show int GigabitEthernet2/0/25 | inc Total output drops
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 3614
ny-swstack01#show int GigabitEthernet2/0/25 | inc Total output drops
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 3614
ny-swstack01#show int GigabitEthernet2/0/25 | inc Total output drops
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 7228
ny-swstack01#show int GigabitEthernet2/0/25 | inc Total output drops
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 7228
ny-swstack01#show int GigabitEthernet2/0/25 | inc Total output drops
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 3614
Outra amostra:
ny-swstack01#show int GigabitEthernet2/0/25 | inc Total output drops
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 10908
ny-swstack01#show int GigabitEthernet2/0/25 | inc Total output drops
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 10908
ny-swstack01#show int GigabitEthernet2/0/25 | inc Total output drops
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 3636
ny-swstack01#show int GigabitEthernet2/0/25 | inc Total output drops
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 3636
ny-swstack01#show int GigabitEthernet2/0/25 | inc Total output drops
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 10908
ny-swstack01#show int GigabitEthernet2/0/25 | inc Total output drops
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 10908
Em ambos os exemplos, estou apenas executando o comando várias vezes, ~ aproximadamente entre comandos.
