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 messages from affecting device performance, disable this
function. Even with the function disabled, the device still sends Fragment Reassembly Time
Exceeded messages.
Examples
# Disable sending ICMPv6 Time Exceeded messages.
<Sysname> system-view
[Sysname] undo ipv6 hoplimit-expires enable
ipv6 icmpv6 error-interval
Use ipv6 icmpv6 error-interval to set the bucket size and the interval for tokens to arrive in the
bucket for ICMPv6 error messages.
Use undo ipv6 icmpv6 error-interval to restore the default.
Syntax
ipv6 icmpv6 error-interval milliseconds [ bucketsize ]
undo ipv6 icmpv6 error-interval
Default
The bucket allows a maximum of 10 tokens, and tokens are placed in the bucket at the interval of 100
milliseconds.
