Class E IPv4 packets
By default, the NetScaler appliance drops any packets if they contain any class E IPv4 address in the source IP or the destination IP fields. If your setup is using class E IPv4 addresses, you can configure the NetScaler appliance to process class E IPv4 packets.
Before you begin
Before you begin configuring a NetScaler appliance to process class E IPv4 packets, note the following points:
-
NetScaler appliances do not support configuring any NetScaler owned IPv4 address (for example, SNIP and VIP) in the class E range. NetScaler appliances only support processing of class E IPv4 packets.
-
A NetScaler appliance internally uses class E IPv4 addresses for the IPv6 feature. The NetScaler appliance does not support both features (processing class E IPv4 packets and IPv6 support) working at the same time. The NetScaler appliance imposes a restriction to not enable the IPv6 feature when processing of class E IPv4 packets is enabled, and vice versa.
Configuration steps
Configuring a NetScaler appliance to process class E IPv4 packets consist of the task of enabling the IPv4 Class E address clients (allowClassEIPv4) Layer 3 parameter.
CLI procedures
To configure the NetScaler appliance to process Class E IPv4 packets by using the CLI:
At the command prompt, type:
-
set l3param -allowClassEIPv4 (ENABLED|DISABLED)
-
show l3param
Sample Configuration:
> set l3param -allowClassEIPv4 ENABLED
Done
> sh l3param
