A VLAN pool enabled newly is not pinging the device. Connectivity issues are not there.

  • Can this be because if ICMP Blocking is enabled?
  • How to check the status of the same?

  • Why you don't give feedback for your questions?! Why you just asked and go away?! You can have to reply and mark answers when it's valid... take a look http://askubuntu.com/tour – Maythux Jun 17 '15 at 10:07

To check whether ICMP is enabled or disabled run the command:

cat /proc/sys/net/ipv4/icmp_echo_ignore_all

The output is 0 or 1:

  • 0 means that ICMP is enabled
  • 1 means that ICMP is disabled

If it's disabled and you want to enable it:

  • change 1 to 0 in the above file

  • Or run the command:

    iptables  -I  INPUT  -i  ech0  -p   icmp  -s  0/0  -d  0/0   -j  ACCEPT

  • @kiranbbnl Good for you, to keep having asnwers to your questions you should always give your feedback with correct or not, If the answer solves your problem you should upvote and mark as answer else when you have sufficient reputation you can downvote. But for now just keep feeding back your questions – Maythux Jun 17 '15 at 10:21
