Any prefix that is less than 64 bits is a route oraddress range that summarizes a portion of the IPv6 address space.For every assignment of an IP address to an interface, the system runs theDuplicate Address Detection (DAD) algorithm to ensure uniqueness.An intermediary transition mechanism is required for IPv6-only nodes tocommunicate with IPv6 nodes over an IPv4 infrastructure. The tunnelingmechanism implemented is the Intra-Site Automatic Tunnel AddressingProtocol (ISATAP). This protocol treats the IPv4 network as a virtual IPv6local-link, with each IPv4 address mapped to a Link Local IPv6 address.Switch InformationUse the Switch Information page to view and configure general deviceinformation, including the system name, location, contact, system MACAddress, System Object ID, date, time, and system up time.To configure general device parameters:1 Click Switch Management > Switch Information.2 Click Edit and enter the fields:– System Name (0-160 Characters) — Enter the user-defined devicename.– System Contact (0-160 Characters) — Enter the name of the contactperson.– System Location (0-160 Characters) — Enter the location where thesystem is currently running.– MAC Address — Displays the device MAC address, which is hardcoded on the switch and thus not editable.– Sys Object ID — Displays the vendor's authoritative identification ofthe network management subsystem contained in the entity.– Date — Enter the current date (mandatory). If SNTP has beendefined, but the SNTP server is not available, the switch uses the dateand time in this field and the Time field. Otherwise this informationis taken from the SNTP server.
