Digi and Cisco
Gord and I put together a Cisco lab. Quagga is great for the routing stuff, but it doesn't emulate switching at all.
We immediately ran into a problem when trying to connect the Cisco console ports to my Digi Portserver II/16: While both ends are RJ45, neither uses anything that could be described as a standard pin-out.
After a bit a of research, I discovered that a Cat5 cable wired as follows works for Cisco consoles. Note that the cable is directly -- the end labelled "Cisco" in the table must go to the Cisco unit, or the cable won't work. I recommend labelling the ends somehow.
| Digi End | |||||||
| Pin 1 | Pin 2 | Pin 3 | Pin 4 | Pin 5 | Pin 6 | Pin 7 | Pin 8 |
| DCD | RTS | GND | TxD | RxD | SG | CTS | DTR |
| w/Gr | Gr | w/Or | Bl | w/Bl | Or | w/Br | Br |
| w/Br | w/Gr | w/Bl | w/Or | Or | Bl | Br | Gr |
| RTS | DTR | TxD | GND | SG | RxD | DSR | CTS |
| Pin 1 | Pin 2 | Pin 3 | Pin 4 | Pin 5 | Pin 6 | Pin 7 | Pin 8 |
| Cisco End | |||||||
Note that I use "w/" as an abbreviation for "White", "Bl" for "Blue", "Gr" for "Green", "Br" for "Brown", and "Or" for "Orange".
