Eu tenho um AP 1260 que atualizei esta manhã. Antes da atualização, o sistema permitia o ssh e respondia a pings na rede, mas agora não responde.
Liguei um cabo serial e navegando pela configuração não consigo encontrar nada errado, e ativar a depuração ssh não está produzindo nenhuma saída.
Tentei regenerar a chave RSA com a chance de causar ssh não ficar online, no entanto, isso não afetou a incapacidade de entrar em contato com a unidade pela rede.
Também tentei ativar o "roteamento IP" e o "ip cef", pensando que poderiam ser o problema, mas sem efeito. Também adicionei uma rota estática padrão ao nosso gateway de gerenciamento, na esperança de que talvez fosse um problema de rota padrão, mas também não ajudou.
Aqui está a versão atual do IOS na unidade:

Todas as sugestões seriam apreciadas, estou bastante perplexo sobre o motivo de isso de repente dar errado.
EDIT : Aqui está a recriação da saída de chaves de criptografia.
DEN-AP01(config)#crypto key generate rsa modulus 1024
% You already have RSA keys defined named DEN-AP01.ds.stackexchange.com.
% They will be replaced.
% The key modulus size is 1024 bits
% Generating 1024 bit RSA keys, keys will be non-exportable...
[OK] (elapsed time was 1 seconds)
