ASR-9001 console configuration

[facundo.ag]

Hi, according to the Cisco ASR 9001 and Cisco ASR 9001-S Routers Hardware Installation Guide :

Step 1 Set your terminal to these operational values: 115200 bps, 8 data bits, no parity, 1 stop bits
(115200 8N1).

But the line configuration of an ASR-9001 router is (IOS XR 5.1.3):

RP/0/RSP0/CPU0:Router#show line console location 0/rSP0/CPU0
Thu Mar 24 11:20:50.960 ART
Tty Speed Overruns Acc I/O
con0/RSP0/CPU0 9600 0/0 -/-

Line "con0_RSP0_CPU0", Location "0/RSP0/CPU0", Type "Console"
Length: 24 lines, Width: 80 columns
Baud rate (TX/RX) is 9600, "No" Parity, 2 stopbits, 8 databits
Template: console
Capabilities: Timestamp Disabled
Allowed transports are none.
RP/0/RSP0/CPU0:POS-RPE-01#

The speed is not configurable in the ASR9000, so, is the speed and stopbits wrong in the documentation?

Cheers,

hi facundo, the direction provided is good, but it is a bit put black and white, there are some stipulations.

some hw variants like the intel based RP's such as RSP440/880 require us to configure the stopbits to 1 manually in the configuration.

the speed however of the console can be set via the config register or alternatively via rommon config

moving forward we do want to set the speed to 115200 default. we kept 9600 around for legacy reasons, but with every async hw capable of doing this 115200 we're looking at making it default.

possibly, documentation was ahead of the implementation :) (never happens :)

cheers!

Hi Xander, as always thanks for the quick reply, it's clear now.

Cisco documentation is awesome, would be no surprise that it's ahead of the implementation :)

Cheers,
