Changed Ping Behavior

Due to upgrading ExtremeXOS 30.1 and later versions to 4.14 Linux kernel, ping success to local IP addresses does not depend on link-layer status.

Earlier releases of ExtremeXOS had customized Linux behavior that meant that pinging a local VLAN interface would fail when the local interface was down. However, in ExtremeXOS 30.2, pinging a local VLAN interface that is down will result in a successful ping.

Virtual Router Redundancy Protocol (VRRP) and Multi-switch Link Aggregation Group (MLAG) can be impacted by this change if locally configured IP addresses are used to determine network reachability. For details, see the ping command.
