Usage guidelines
ICMPv6 Time Exceeded messages are sent to the source of IPv6 packets after the device discards IPv6
packets because hop or reassembly times out.
To prevent too many ICMPv6 error packets from affecting device performance, disable this function. Even
with the function disabled, the device still sends Fragment Reassembly Time Exceeded packets.
Examples
# Disable sending ICMPv6 Time Exceeded packets.
<Sysname> system-view
