Server Farm The ACE is to load balance client requests for content to a server farm.
1. In the Server Farm field, select the server farm for this policy map action.
2. In the Backup Server Farm field, select the backup server farm for this action.
3. Check the Sticky Enabled check box to indicate that the backup server farm is sticky. Clear
this check box if the backup server farm is not sticky.
4. Check the Aggregate State Enabled check box to indicate that the operational state of the
backup server farm is taken into consideration when evaluating the state of the load-balancing
class in a policy map. Clear this check box to indicate that the operational state of the backup
server farm is not taken into consideration when evaluating the state of the load-balancing
class in a policy map.
Server Farm-NAT The ACE is to apply dynamic NAT to traffic for this policy map.
1. In the NAT Pool ID field, enter the number of the pool of IP addresses that exist under the
VLAN specified in the VLAN Id field. Valid entries are integers from 1 to 2147483647. For
information on configuring NAT pools, see Configuring VLAN Interface NAT Pools and
Displaying NAT Utilization, page 10-32.
2. In the VLAN ID field, select the VLAN to use for NAT. Valid entries are integers from 2 to
4094.
3. In the Server Farm Type field, indicate whether the server farm is a backup or primary server
farm.
Set-IP-TOS The ACE is to set the IP Differentiated Services Code Point (DSCP) bit in the Type of Service
(ToS) byte. Once the IP DSCP bit is set, other Quality of Service (QoS) services can then operate
on the bit settings.
In the IP TOS Rewrite Value (Bytes) field, enter the IP DSCP value. Valid entries are integers from
0 to 255.
Sticky-Server Farm The ACE is to load balance client requests for content to a sticky server farm.
In the Sticky Group field, select the sticky group to be used for requests that match this policy map.
ACE displays all stick groups configured on the virtual context; however, only the following
sticky types are applicable for a load balancing policy map: IP Netmask, IPv6 Prefix, and SSL.
ACE displays an error message if you choose an incorrect sticky type.
