server 1
1. Select service 80.
>> Main# /cfg/slb/virt 1/service 80
2. Set the service timeout value.
>> Virtual Server 1 http Service#
3. Save configuration.
>> Virtual Server 1 http Service# apply
>> Virtual Server 1 http Service# save

IPv6 and Server Load Balancing

Alteon provides a full range of SLB options for Internet Protocol version 6 (IPv6).

Pure IPv6 Environment

In this environment, IPv6 virtual address traffic is sent to IPv6 real servers, where Alteon supports
• Layer 4 and Layer 7 traffic processing for HTTP and HTTPS, including application acceleration,
and Layer 7 traffic processing for DNS over UDP.
• Layer 4 SLB for all other applications.

Mixed IPv4 and IPv6 Environment (Gateway)

In this environment, IPv6 client traffic is sent to IPv4 real servers, or IPv4 client traffic is sent to
IPv6 real servers. Real server groups can contain mixed IPv4 and IPv6 servers.
When the IP version of the server is different from the IP version of the client, Alteon converts the
client packet to a packet of the server IP version before it is forwarded to the server. In this
environment, Alteon supports
• Layer 4 and Layer 7 traffic processing for HTTP and HTTPS, including application acceleration.
• Layer 4 SLB and SSL offloading for SSL.
• Basic Layer 4 SLB for UDP and TCP.
Note: Since IPv6 does not allow intermediary routers or switches to fragment packets, internal
translation of the maximum IPv4 packet (MTU of 1500) cannot be translated without fragmenting.
Therefore, all IPv4 real servers must use IPv6 SLB to be configured with a maximum MTU less than
or equal to 1480.
For example, in the Windows 2003 environment, run REGEDIT to add a new parameter to the
registry in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\
Tcpip\Parameters\Interfaces\xx (where xx is the correct interface for the configured IP
address), with the keyword MTU, using REG_DWORD with a decimal value of 1480.
