NETCONF cli length issue

Hello guys,

I am trying to make a script to retrieve vendor's for all hardware addresses (MAC) via NETCONF. The command is simply 'show arp | match ae0 ' but for some reason it times out waiting for the RPC reply. I am guessing it's due to cli length, if I log in to the router and issue 'show cli screen-length 0' and run the script again, it works. Is there any way to pass this cli option as parameter?

Thanks for any advice.
