Table 12-22 Generic Server Load Balancing Policy Map Actions

Action Description

Drop The ACE is to discard packets that match this policy map.

In the Action Log field, specify whether the dropped packets are to be logged in the software.

Forward The ACE is to forward the traffic that match this policy map to its destination.

Reverse Sticky Reverse IP stickiness is an enhancement to regular stickiness and is used mainly in FWLB. It

ensures that multiple distinct connections that are opened by hosts at both ends (client and server)

are load-balanced and stuck to the same firewall. Reverse stickiness applies to such protocols as

FTP, RTSP, SIP, and so on where there are separate control channels and data channels opened by

the client and the server, respectively. For complete details about reverse stickiness, see the Server

Load-Balancing Guide, Cisco ACE Application Control Engine.

In the Sticky Group field, choose an existing IPv4 IP netmask or IPv6 prefix sticky group that you

want to associate with reverse IP stickiness.

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.
