Problem with authentication on ASR1002-X

[Aleksandr Pashko]

Hello everyone!

We fix a periodic problem with authentication on our 2 ASR1002-X.

It is impossible to get to the device either under local accounts or through tacacs+, only reboot helps.

The software on the two ASRs is the same.

Cisco IOS XE Software, Version 16.09.04
Cisco IOS Software [Fuji], ASR1000 Software (X86_64_LINUX_IOSD-UNIVERSALK9-M), Version 16.9.4, RELEASE SOFTWARE (fc2)

NAME: "Chassis", DESCR: "Cisco ASR1002-X Chassis"
PID: ASR1002-X , VID: V01 , SN: FOX1731G02H

 - If it's a periodic problem then configure a syslog server on the ASA, if possible enable debugging , if a login then blocks (afterwards) , examine the messages which were send to the syslog server, it may provide insights.

hi,

can you share the line vty config? post a show run | sec line vty

make sure to increase the number VTY lines and lower the exec and session timeouts.
