Locking and Unlocking Delegated Services
This feature enables the Global Administrator to lock any service that was delegated to a vADC,
preventing the vADC Administrator from changing them. Each delegated service can be individually
locked, enabling the Global Administrator to have more flexibility and control when configuring
policies for vADC Administrators.
Monitoring and Maintaining vADCs
The vADC Administrator monitors vADCs in essentially the same manner as a traditional ADC,
except for those features and functions which are reserved for the Global Administrator. In addition
to the standard data that are displayed in a traditional vADC, many of the information displays also
include additional data about each of the vADC instances.
Synchronizing vADCs
Each vADC individually supports configuration synchronization. Unlike the synchronization
mechanism used by the Global Administrator, which is responsible for synchronizing elements such
as VLANs and throughput limits, this mechanism is controlled by the vADC administrator and
synchronizes elements such as filters, SLB groups, virtual IPs, and all the vADC SLB settings.
If the vADC Administrator needs to synchronize vADC configurations, the synchronization is done in
the same manner as traditional ADCs using the
/oper/slb/sync
command. For more details, see
the Alteon Application Switch Operating System Command Reference.
Resource Management
ADC-VX manages vADC resources by limiting the resource consumption of vADCs. You can enable or
disable this feature.
• Enabled (default for Alteon 5224)—Limits the resources available to vADCs. See Limiting
Resource Consumption of vADCs, page 411 .
• Disabled (default for Alteon 5412)—Enables sharing of any extra available resources between
vADCs. See
Sharing Idle Resource Consumption with Other vADCs, page 410 .
The Global Administrator can switch between these two modes. When changing modes, all vADCs
remain active and operational. Any connections beyond the allowed maximum resource
consumption are gracefully timed out rather than discarded.
Sharing Idle Resource Consumption with Other vADCs
In share (disabled) mode, although resources are guaranteed to all vADCs, any resources that are
used from the idle pool can be allocated permanently to other vADCs. This behavior may decrease
the performance of an application as the idle resource is no longer available to the vADC associated
with that application.
For example, if an SP or MP uses unassigned CUs, these unassigned CUs are used equally across the
vADCs that require the resources.
