IPv6 Hop Limit Specify the maximum number of hops (from 1 to 255) in router advertisements. This is the
maximum number of hops on which an IPv6 packet is allowed to transmit before it is discarded by
an IPv6 router, which is similar to the TTL field in IPv4.
ICMPv6 Rate
Limit Bucket
Size
Specify the maximum number of ICMPv6 error messages (from 1 to 200) which are allowed to
transmit in a given time interval. If the bucket is full, subsequent error messages are suppressed.
ICMPv6 Rate
Limit Error
Interval
Specify the time period (from 0 to 2147483647 milliseconds) during which ICMPv6 error messages
of up to the bucket size can be transmitted. 0 means no limit.
Apply Click Apply to save your changes to the Switch’s run-time memory. The Switch loses these

your changes to the non-volatile memory when you are done configuring.
