D E L L C O N F I D E N T I A L – P R E L I M I N A R Y 3 / 1 9 / 1 5 - F O R P R O O F O N LY 70 Dashboard Switch Management This section describes how to set system parameters, such as security features, switch software, system time, logging parameters and more.

It contains the following topics:

• IP Addressing Overview

• Switch Information

• IPv4 Addressing

• IPv6 Addressing

• File Update and Backup

• Domain Name System (DNS)

• Time Synchronization

• Management Security IP Addressing Overview The device functions as an IPv6-compliant host, as well as an IPv4-host (also known as dual stack). This enables device operation in a pure-IPv6 network, while ISATAP tunnel enables device operations in combined in a combined IPv4/IPv6 network.

Difference Between IPv4 and IPv6 Addressing The primary difference between IPv4 to IPv6 is the length of network addresses. IPv6 addresses are 128 bits, whereas IPv4 addresses are 32 bits.

Thus, IPv6 addresses enable the use of many more unique addresses.

The 128-bit IPv6 address format is divided into eight groups of four hexadecimal digits. Abbreviation of this format by replacing a group of zeros with double colons (::) is acceptable. IPv6 address representation can be further simplified by suppressing the leading zeros.





All IPv6 address formats are acceptable, yet for display purposes, the system displays the most abbreviated form, which replaces groups of zeros with double colons and removes the leading zeros.

D E L L C O N F I D E N T I A L – P R E L I M I N A R Y 3 / 1 9 / 1 5 - F O R P R O O F O N LY Template Last Updated - 2010 Switch Management FILE LOCATION: C:\Users\vijaya_devakumar_dev\Documents\PowerConnect\Astute\Docs for Web Posting\Astute_Admin_Guide_sources_MIF7\FM\Dell_Astute_SwitchManagement.fm IPv6 Prefixes While Unicast IPv6 addresses written with their prefix lengths are permitted, in practice their prefix lengths are always 64 bits, and therefore are not required to be expressed. Any prefix that is less than 64 bits is a route or address range that summarizes a portion of the IPv6 address space.

For every assignment of an IP address to an interface, the system runs the Duplicate Address Detection (DAD) algorithm to ensure uniqueness.

An intermediary transition mechanism is required for IPv6-only nodes to communicate with IPv6 nodes over an IPv4 infrastructure. The tunneling mechanism implemented is the Intra-Site Automatic Tunnel Addressing Protocol (ISATAP). This protocol treats the IPv4 network as a virtual IPv6 local-link, with each IPv4 address mapped to a Link Local IPv6 address.

IPv4 Addressing

You can assign IPv4 addresses to an interface in the following ways:

• Static Assignment

• DHCP Assignment - Default When the interface is configured as a DHCP client (the default), it requests an IP address from the DHCP server. It then sends Address Resolution Protocol (ARP) packets to confirm the uniqueness of the IP address. If the ARP response shows that the IP address is in use, the switch sends a DHCPDECLINE message to the DHCP server, and sends another DHCPDISCOVER packet that restarts the process.

If the DHCP server is not accessible, the device uses the default IP address 192.168.2.1.

Use the IPv4 Addressing page to configure a static device IPv4 address.

When an IP address is assigned, it is checked for uniqueness in the following

way:

• A gratuitous ARP request is sent three times every three seconds.

• If after (3+1)*3 = 12 seconds the switch has not received the ARP response, the IP address is considered to be unique.

• During the procedure the switch has to reply to gratuitous ARP and probe ARP requests with the validated IP address.

–  –  –

The IP address is assigned even if the above validation procedure concludes that the IP address in question is not unique, but a SYSLOG message is generated.

In addition to the above validation procedure every time a switch receives an ARP request with a sender IP address that is equal to its IP address defined on the input interface it sends a SYSLOG message informing of IP duplication, containing the sender IP and MAC addresses, from the received ARP message.

NOTE: System Routing Mode: X1008/P, X1018/P, X1026/P devices are in Layer 2 mode by default. X1052/P, X4012 devices are in Layer 2+ mode by default.

The X1008/P X1018/P and X1026/P devices can be configured in either in L2,

or L2+ mode. For these devices:

• In Layer 2 mode, the following are supported: Dot1x (guest VLAN, Dynamic VLAN Assignment, and Multi Session. Only one IP address can be assigned on a VLAN.

• In Layer 2 + Routing mode, the following are supported: IPv4 Routing and IPv6 Routing. Dot1x (guest VLAN, Dynamic VLAN Assignment, and Multi Session) is not supported. Multiple static IP addresses can be assigned on one or more interfaces (ports, LAGs or VLANs).

The X1052(P) and 4012 (P) devices are always in L2+ mode.

IPv4 Default Gateway A default gateway can be assigned on any IPv4 interface in the system (port, LAG or VLAN).

The IPv4 default gateway can be assigned statically or received from a DHCP server according to the configuration in the IPv4 Addressing page. The default gateway is received along with the IP address from the DHCP server. DHCP assignment is the default.

IPv4 Addressing To assign an IP address to an IPv4 interface, and to define subnets to which

traffic can be routed:

1 Click Switch Management IPv4 Addressing.

The previously-assigned IP addresses are displayed.

IPv6 Addressing

This section describes the following sections:

• IPv6 Global Parameters

• IPv6 Interface

• IPv6 Address

• IPv6 Default Gateway

• IPv6 Neighbors

–  –  –

IPv6 Global Parameters

To define IPv6 global parameters:

1 Click Switch Management IPv6 Addressing Global Parameters.

2 Click Edit and enter values for the following fields:

IPv6 Routing —Select Enable/Disable to enable/disable IPv6 routing. If • this is not enabled, the device acts as a host (not a router) and can receive management packets, but cannot forward packets. If routing is enabled, the device can forward the IPv6 packets.

ICMPv6 Error Rate Limit Interval (0-2147483647) — Enter how often • the ICMPv6 error messages are generated in milliseconds. The value of this parameter together with the Bucket Size parameter (below) determines how many ICMP error messages may be sent per time interval, for example, a rate-limit interval of 100 ms and a bucket size of 10 messages translates to 100 ICMP error messages per second.

ICMPv6 Error Rate Limit Bucket Size (1-200) — Enter the maximum • number of ICMP error messages that can be sent by the device per interval. The value of this parameter together with the ICMP Error Rate Limit Interval parameter determines how many ICMP error messages may be sent per time interval, for example, a rate-limit interval of 100 ms and a bucket size of 10 messages translates to 100 ICMP error messages per second.

IPv6 Hop Limit (1-255) —Enter the maximum number of intermediate • routers on its way to the final destination to which a packet can pass. Each time a packet is forwarded to another router, the hop limit is reduced.

When the hop limit becomes zero, the packet is discarded. This prevents packets from being transferred endlessly.

IPv6 Link Local Default Zone Interface — Select an interface to egress • a link local packet without a specified interface or with the default zone 0.

IPv6 Interface

To add a new IPv6 interface:

1 Click Switch Management IPv6 Addressing IPv6 Interface.

The currently-defined IPv6 addresses on the selected interface are displayed.

This list contains routers that are candidates to become the switch default router for non-local traffic. The switch randomly selects a router from the list. The switch supports one static IPv6 default router.

Dynamic default routers are routers that have sent router advertisements to the switch IPv6 interface.

When adding or deleting IP addresses, the following events occur:

• When removing an IP interface, all of its default gateway IP addresses are removed.

• Dynamic IP addresses cannot be removed.

• An alert message is displayed after a user attempts to insert more than one IP address.

• An alert message is displayed when attempting to insert a non-Link Local type address.

To configure a router:

1 Click Switch Management IPv6 Addressing IPv6 Default Gateway.

The previously-defined routers are displayed with the following fields:

Default Gateway IPv6 Address — The router’s address.

– Interface — The interface on which the router is accessed.

– Type — The means by which the default gateway was configured. The –
