SSH agent vs. CISCO ACS 5.4

[mr.fiskus]

Hi guys,
I have running Zabbix server with correct setup ssh access. I can use zabbix for ssh checks on linux server and cisco boxes.

But when I can use ssh zabbix check for Cisco ACS boxes, I get error message from zabbix-server.log:

item [IP:ssh.run[check]] became not supported: Cannot obtain authentication methods: Would block requesting userauth list

On destination ACS boxes I have create specific user.

I use username and password authentication type.

Zabbix server specification:
