Hello, According to Juniper' website the CIP card (Control Interface Card) holds the management ports for Routing Engine 0 and Routing Engine 1. Ports are grouped as Host0 and Host1.
http://www.juniper.net/techpubs/hardware/t640/t640-hwguide/hw-cip.html#hw-re-ports By default, the auxiliary port is disabled. I enabled the auxiliary port but I am not able to connect to the router using this port. http://www.juniper.net/techpubs/hardware/t640/t640-hwguide/pinouts-db9.html#pinouts-db9 According to the information above, both ports should work as RS-232 and have identical pinout. I am trying to access the auxiliary port of my T-640 using a Cisco 2511 through reverse telnet. My console connection on the same Cisco 2511 towards the same router is working without any problems. The only difference between the console connection and the aux one is that on the aux connection CTS and DSR are down: #sh line 2 Tty Typ Tx/Rx A Modem Roty AccO AccI Uses Noise Overruns * 2 TTY 9600/9600 - inout - - 10 12 0 0/0 Line 2, Location: "xxxxx-re0-aux", Type: "" Length: 24 lines, Width: 80 columns Baud rate (TX/RX) is 9600/9600, no parity, 2 stopbits, 8 databits Status: Ready, Connected, Active Capabilities: EXEC Suppressed, Modem Callout, Modem RI is CD No login banner Modem state: Ready Special Chars: Escape Hold Stop Start Disconnect Activation ^Cx none - - none Timeouts: Idle EXEC Idle Session Modem Answer Session Dispatch 00:15:00 00:30:00 none not set Modem type is unknown.
