Timos VSR 14.0.R7 cannot ping

Post by ksumopy » Fri Jun 22, 2018 12:55 am

Hi Folks,

I wanna ask about how to check and troubleshooting vnet interface on my Timos VSR.
I use eve-ng on my personal laptop with core i7/16Gb of RAM. the timos can run correctly but i'm not be able to ping both sides.
tried to collect tcpdump from vnet0_1 and see constant arp request present on the screen. could you please give a clue in regard of my problem here.

Code: Select all
