Page 38: Snmp Settings
xStack DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch SNMP Settings Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) designed specifically for managing and monitoring network devices. SNMP enables network management stations to read and modify the settings of gateways, routers, switches and other network devices.
Page 39: Ip Address Assignment
xStack DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch IP Address Assignment An IP Address must be assigned to each switch, which is used for communication with an SNMP network manager or other TCP/IP application (for example BOOTP, TFTP). The Switch's default IP address is 10.90.90.90. The user may change the default Switch IP address to meet the specification of your networking address scheme.
Page 40 xStack DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch In the above example, the Switch was assigned an IP address of 10.53.13.26 with a subnet mask of 255.0.0.0. The system message Success indicates that the command was executed successfully. The Switch can now be configured and managed via Telnet and the CLI or via the Web-based management.

Page 48: Packet Format
xStack DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch Packet Format As in IPv4, the IPv6 packet consists of the packet header and the payload, but the difference occurs in the packet header which has been amended and improved for better packet flow and processing. The following will outline and detail the IPv6 enhancements and parts of the IPv6 packet, with special attention to the packet header.
Page 49: Extension Headers
xStack DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch Extension Headers Extension headers are used to identify optional parameters regarding IPv6 packets such as routing, fragmentation of packets or authentication parameters. The types of extension headers supported are Hop-by-Hop, Routing, Fragment, Destination Options, Authentication and Encapsulating Security Payload.
Page 50: Types
xStack DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch looks long and cumbersome, there are some compression rules that will shorten the format of the IPv6 address to make it more compatible to the user. One such compression rule that is used is to remove leading zeros from any 16-bit hexadecimal value. This is only for zeros that begin the value, not for zeros within the value or ones that are ending the value.
Page 51: Icmpv6
xStack DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch ICMPv6 Network professionals are already very familiar with ICMP for IPv4, which is an essential tool in the IPv4 network, relaying messages about network problems and the general condition of the network. ICMPv6 is the successor to the IPv4 version and performs many of the same basic functions as its precursor, yet is not compatible with ICMPv4.
Page 52: Duplicate Address Detection (Dad)
xStack DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch Duplicate Address Detection (DAD) DAD messages are used to specify that there is more than one node on a local link possessing the same IP address. IPv6 addresses are only leased for a defined period of time. When that time expires, the address will become invalid and another address must be addressed to the node.
Page 53: Ip Address
xStack DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch IP Address The IP Address may initially be set using the console interface prior to connecting to it through the Ethernet.
