I have a Cisco UCS-C460 server on which I have ESXi6.0 installed. I have vCenter server 6.0 to which I have added this ESXi host. I have Cisco CSR1000v router installed on this host. I added a serial port to it to connect over network. I am unable to use telnet to connect to this host.
I have 3 other Cisco UCS servers with ESXi 6.0 installed. On all these servers I can not connect using telnet.
I have another Cisco UCS ESXi 5.5 server on which any VM allows telnet connection.
What am I missing?
Thanks in advance.
