DLCS L
IMITATIONS
Consider the following limitations concerning data received from WINS snooping:
• DLCS does not work for the WINS server. This is because the WINS server does not
send NETBIOS packets on the network (these packets are address to itself).
• When the IP address of a host is changed, and the host is not immediately rebooted,
the old host-to-IP address mapping is never deleted. You must delete the mapping of
the host-to-IP address through the EEM Policy Manager.
• When the host is moved from one port to another port on a switch, the old entry
does not age out unless the host is rebooted or a user login operation is performed
after the host is moved.
• DLCS information is dynamic, therefore, if the switch is rebooted, the information is
lost. This information is still stored in the policy-server. To delete the information
from the policy system, you must explicitly delete configuration parameters from the
EEM Policy Applet user interface. As a workaround, you may delete the switch that
was rebooted from the list of managed devices in the EEM Inventory Applet, and
re-add the switch to the Inventory Manager.
• DLCS is not supported on hosts that have multiple NIC cards.
• IPQoS is not supported to a WINS server that is serving more than one VLAN. If
you attempt to add a WINS server to serve more than one VLAN, and there are
IPQoS rules defined for that server, the command to add the WINS server is rejected.
