On the server side we are able to locate the below: ... 2019 -09-11 12:17:57,159 Thread-26 ERROR comm - comm.TransportContext : Error In Completing The SSL Handshake.

Hello, In our case, we have implemented the below command as to overcome the registration failure to the local satellite server: http client secure-verify-peer disable. Also, the satellite server doesnt carry hostname, instead its reachable using its IP address. We didnt modify the crypto settings. Thanks

Hello Patoberli, checks performed: from server to wlc: the script logs-in and retrieves the AP list successfully from server to APs: using native telnet on Windows server we can telnet to the AP(s) and log in using the credentials defined in config.ini I think that this is also depicted below but it doesnt make sense because the script initially reports that its connecting to the AP(s) but then it reports error in connecting using telnet: snip> 2019-04-08 21:37:26,867 wlanpoller INFO: WLC processing complete; waiting for AP data collection to complete 2019-04-08 21:37:29,253 wlanpoller INFO: KXXXX : AIR-CAP1602I-E-K9 - Connected - IP addr: a.b.c.d 2019-04-08 21:37:29,253 wlanpoller INFO: KXXXX : AIR-CAP1602I-E-K9 - Collecting poller output .. .. .. 2019-04-08 21:38:18,674 wlanpoller CRITICAL: KXXXX : AIR-CAP1602I-E-K9 - Connection error (telnet://a.b.c.d) Telnet instance has no attribute 'get_transport' <snip> The way i interpret the Critical error is that the script cant allocate the necessary telnet resource as such it fails, but this is only my understanding... Thanks

Hello Leo, We have about 500 Access points in total. Access points failures are not frequent and of course not sure even if the low number of failures is associated with the flash corruption issue. We are just eager to run the script, identify the candidate Access Points to fail and proceed with the WLC upgrade. But, the script fails so we are in the dark.

Hi Leo, Is there any way to enable additional debugging information for the script? The failure reason doesnt make any sense and i dont really know how to troubleshoot this further. Thanks

Hello Patobeli, The server is indeed in the same vlan as the management vlan of the WLC, not the APs though... I dont think its a telnet/ssh problem, the credentials are correct. Please see the log output for a specific ap (all the other APs have the same log ) <snip> 2019-04-08 21:37:26,867 wlanpoller INFO: WLC processing complete; waiting for AP data collection to complete 2019-04-08 21:37:29,253 wlanpoller INFO: KXXXX : AIR-CAP1602I-E-K9 - Connected - IP addr: a.b.c.d 2019-04-08 21:37:29,253 wlanpoller INFO: KXXXX : AIR-CAP1602I-E-K9 - Collecting poller output .. .. .. 2019-04-08 21:38:18,674 wlanpoller CRITICAL: KXXXX : AIR-CAP1602I-E-K9 - Connection error (telnet://a.b.c.d) Telnet instance has no attribute 'get_transport' <snip> What do you think?

Hello Leo, Its actually an old one, under 8.2.x, thats why we would like to run the script and then proceed with the upgrade. Does the script support the 8.2.x releases? Thanks

Hello Team, So we are about to upgrade a wlc pair for our customer and as a pre-requisite we are following the instructions of this document:https://www.cisco.com/c/en/us/support/docs/wireless-mobility/wireless-lan-wlan/213317-understanding-various-ap-ios-flash-corru.html#anc22 The python/pip are successfully installed, edited the config.ini to match our information and gave it a shot. After a while, the results are printed but It seems that we are facing a fundamental error for all APS: <snip> Errors ============================================================ AP connection error: Telnet instance has no attribute 'get_transport': 92 AP connection error: timed out : 15 AP connection error: telnet connection closed: 2 ============================================================ Has anyone faced the same error? Any tips/ideas ? To note, we are using windows server 2012-64bit instead of the Win10 purely because this is the only available server to access the management network of the WLC. Also, telnet client is enabled on the Windows Server. Thank you Panayiotis

Hello Xander,
can we run the "cfs check" outside a maintenance window?
on another note, we are experiencing long (roughly around to 20m) output delays when executing the "show bgp ipv4 uni neighbors x.x.x.x advertised-routes" , especially after modifying the attached as-path rpl. Could this be related to low memory?
Thanks

Hello All,
We have deployed the Satellite Enhanced edition 6.1.0 in our environment we are in the process of registering a few ASR boxes to it. It seems that there is problem when the the HTTPS is used, resulting in registration failure while for the HTTP the same box can register successfully.
We have ended up with the below messages that we try to figure out and resolve:

Hello Jan,
Have you tried the "import from device" option while in Lineup perspective?
This option usually allows you to import from a DCM, you need to select the DCM, then output services will be presented which you can select the ones of your interest. Make sure that you assign folder,lineup names as to get imported.
Thanks,
Panayiotis

Hello,
to start with, for every drd input (4 at each drd) you can lock one transponder and then receive the video services of the transponder for multiplexing to ip over the GBE card.. For this action, we usually get the LDCM-SAT-1/per rf input. This license allows one multiple transport stream per transponder.
Then, if the services are not FTA, you need to add the amount of the CI/CA modules going to be used for descrambling, as such one LDCM-CI-1 for each CI slot.
Never used the 8VSB before.Last, for the FEC license, this is purely driven by your requirements but i am not sure if you need a co-processor on top of the GBE card.
hope it helps
Thanks
