support for IOS-XR based Ciscos about ulg HOT 4 CLOSED

Hi!

The IOS-XR is not yet supported. I would really like to add support but I was unable to obtain exec access to any IOS-XR router yet. (You know, there are plenty of testing or lab boxes with IOS, but virtually none with IOS-XR. And when somebody has one he uses it in a serious production network so nobody wants to give an access to a stranger.)

If you would be interested in writing and contributing an IOS-XR support to ULG I would be really glad. There are some commented-out debugging code. I suggest you to start with uncommenting line #908 and then you can see the whole SSH sessions in the logfile. Warning: There are passwords in plaintext included. Perhaps you can send me the log so I can have a look at it and I might try to write some supporting code. But it is going to be totally untested and therefore unlikely to work immediately.

Cheers,
Tomas

Hi Tomas,

thanks for your quick response.

We have a lab chassis for which I can grant you access if you wish.
Right now we are in the process of upgrading our ASR9ks, so the box is
used for upgrading the RSPs of the production chassis to keep the
downtimes low. I guess this should be done mid of next week and you can
then have access to this box if you like.

One thing I figured out myself, is that the
STRING_EXPECT_SHELL_PROMPT_REGEXP doesn't match for IOS-XR, I changed
that to add / and : to the regex and this now works
(STRING_EXPECT_SHELL_PROMPT_REGEXP = '\n[a-zA-Z0-9./:_-]+(>|#)').
Now the login to the box + first cmd works, but I guess the BGP regex
than again doesn't match. The output of ulgcisco.log (after the initial
login) is:

RP/0/RSP0/CPU0:core1#

So you can see there are some (minor) differences between IOS and IOS-XR
output of the same command.
The raised error is pexpect session failed: Connection timeout

If you can confirm, that this is a regex problem, I'll dig deeper into it.

Thanks again for your help,
best regards,
Kurt

Cheers,
Tomas

Hi!

I would be glad if you could give me an access to your testing IOS-XR box. And I suspect that it is going to be more complicated to accommodate ULG for IOS-XR than making few changes in regexps. But I do not know for sure because I haven't seen all the needed outputs from IOS-XR yet.

Could you set up some sort of lab environment for ULG then? I would like to see some established and few active BGP sessions (both ipv4 and 6) and some routes in BGP. Or if it is not possible I can try to debug IOS-XR SSH interaction module on your live box and then obtain text dumps of needed command outputs and create a mockup router module for them.

Perhaps we can switch our discussion about the IOS-XR to e-mails.

Cheers,
Tomas

Just closing old issue... Support for IOS-XR is already present.
