Before you begin
Before changing DCN information notice the following precautions:
• When the IS-IS parameters are changed this may cause the network element to
restart, resulting in a temporary loss of association. If the network element is
participating in a GR scheme this may cause an automatic protection switch. A
warning message is displayed
• If the values of the IS-IS parameters are incorrect this may cause instabilities in the
DCN and may result in many network elements becoming unmanageable. A
warning message is displayed
• Do not create an area with the area ID 0000, because this is already the default
area ID for all newly created NEs
• Choosing the static value for the connection type option makes the gateway
network element a single point of failure in the management of the network
element
• When the LAN IS-IS Level is set to None (NO-IS-IS) a network element cluster that
is not directly connected to the management system LAN (10BaseT) may become
unmanageable when None is chosen for the cluster gateway. None also prevents
traffic from one cluster from being routed to another cluster over the LAN
• The value of the designated router priority is composed in a specialized plan, so do
not change it unless this plan is available
• If an additional manual area address is provisioned when the computed area
address table (CAAT) is full, this may cause a loss of entries in the CAAT which
results in a loss of association. If the network element is participating in a GR
scheme this may cause an automatic protection switch. A warning message is
displayed
• Before starting to change the provisioned network element information, all
information about the DCN must be available.
