Hi Kannan

this seems a bit odd to me - you have "port 830" -- but ssh ? and the cisco IOS NED ?

question: are you trying to connect w/ NETCONF? or SSH?

set devices device router-0 address 172.16.49.80 port 830

set devices authgroups group csrgroup default-map remote-name admin remote-password admin remote-secondary-password admin

set devices device router-0 authgroup csrgroup

set devices device rou ter-0 state admin-state unlocked

set devices device router-0 device-type cli ned-id cisco-ios protocol ssh

set devices device router-0 trace pretty

I would think if it's a normal cisco IOS device, and SSH is enabled, you do not need to specify anything off of the default port.

it's unclear to me why you specify "port 830"

perhaps you can try ?

thanks
