VIP-In-Service A VIP is to be enabled for server load-balancing operations.
KAL-AP-TAG The KAL-AP-TAG feature allows the Cisco Global Site Selector (GSS) proprietary KAL-AP
protocol to extract load and availability information from the ACE when a firewall is positioned
between the GSS and the ACE. This feature allows you to configure a tag (name) per VIP for a
maximum of 4,096 tags on an ACE. This feature does not replace the tag per domain feature. For
more information about this feature, see the Configuring Health Monitoring chapter in the Server
Load-Balancing Guide, Cisco ACE Application Control Engine.
Note The KAL-AP-TAG selection is not available for the class-default class map.
In the KAL-AP-Tag Name field, enter the name as an unquoted text string with no spaces and a
maximum of 76 alphanumeric characters.
The following scenarios are not supported and will result in an error:
• You cannot configure a tag name for a VIP that already has a tag configuration as part of a
different policy configuration.
• You cannot associate the same tag name with more than one VIP.
• You cannot associate the same tag name with a domain and a VIP.
• You cannot assign two different tags to two different Layer 3 class maps that have the same
VIP, but different port numbers. The KAL-AP protocol considers these class maps to have
the same VIP and calculates the load for both Layer 3 rules together when the GSS queries
the VIP.
