Configuring Server Farms
Table 6-7 Predictor Method Attributes
Predictor Method Description / Action
Hash Address The ACE selects the server using a hash value based on the source or destination IP address.
To configure the hash address predictor method:
1. In the Mask Type field, indicate whether server selection is based on source IP address or the
destination IP address:
– N/A—This option is not defined.
– Destination—The server is selected based on the destination IP address.
– Source—The server is selected based on the source IP address.
Note If you configure the server farm with IPv6 and IPv4 Hash Address predictors at the
same time, both predictors must have the same mask type.
2. In the IP Netmask field, select the subnet mask to apply to the address. If none is specified,
the default is 255.255.255.255.
3. In the IPv6 Prefix-Length field, enter the IPv6 prefix length. If none is specified, the default
is 128.
