Class E IPv4 packets

August 1, 2023

Contributed by:

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
