DESCRIPTION
This field displays how long (in seconds) that the global address remains preferred.
This field displays how long (in seconds) that the global address is valid.

names.
Click Restart to send a new DHCP request to the DHCPv6 server and update the IPv6 address and

DESCRIPTION
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.
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.
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.
Click Apply to save your changes to the Switch's run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel to save
your changes to the non-volatile memory when you are done configuring.
Click Cancel to begin configuring this screen afresh.
Click Clear to reset the fields to the factory defaults.
