I purchased F5 LTM virtual lab and after using it for 8-10 hours, my devices started getting off automatically frequently. What is the reason. Please suggest. 

Hello Manish, i also purchased Cisco Nexus virtual lab from uninets. and me also facing the same issue like devices are getting powered off Frequently. at the same time i approached support team and they suggest me that i need to clear my browser history and cookies. or try to login into different browser and it will work for me. so i suggest you to try to login with Mozill Firefox browser it will work for sure.

Hi Support Team i am facing the same issue that devices are getting off and some time i lost console tab. some time back console is working fine but now i am facing this issue. please help

Hi Rohan this is not any issue.

1) If your devices are getting Power OFF frequently. so you need to clear your browser history or cookies. otherwise try to login in different browser.

2) If  your console tab getting Off in that case you need to check your Internet either any packet loss or is there any internet speed issue. 

Just to inform you guys I never faced such kind of issues with my virtual labs (Cisco ACI and Cisco SD-WAN) from uninets. They always run smooth at least for me. But still thanks for the post in case it happens I immediately follow the steps mentioned rather than going to uninets support. 

i have buy F5 LTM virtual lab for 30days. when i try to enter default username and password (ROOT/DEFAULT) the f5 box was not responding. please help

let me tell you in detail. when the f5 box ask for username and password you have to enter root/default. while you enter the default username and password it will ask you again to enter the current password. after that you can the the admin password.
