Chapter 8 Managing PNNI Nodes and PNNI Routing
Maintaining a Persistent Network Topology for CWM
Step 3 Enter the dsptopogw command to verify that the current node is functioning as a gateway, as shown in
the following example.
8830_CH.1.PXM.a > dsptopogw
Admin State : ENABLED Operational State ENABLED
The following two states are associated with the topology database:
• the admin state is set by CLI or CWM, and can be either enabled or disabled.
• the operational state can be ENABLED, ENABLING, DISABLED, DISABLING, or FULL.
By default, the node’s admin and operational states are DISABLED.
Table 8-23 describes the valid operational and admin state combinations, and how they affect CWM
access.
The gateway node contains information only for the nodes which are up and reachable when you add the
gateway node into a peer group. It is not necessary to create a gateway node before creating a peer group,
because the database contains all the reachable nodes that were in the peer group when it was first added.
However, if a node is down or unreachable when you add a gateway node to a peer group, the information
for the downed node will not be present in the topology database of this gateway node.
Table 8-23 Valid Operational and Admin State Combinations
Admin State Oper State Description CWM Access
Enabled Enabled
The node is functioning as a gateway node. You can perform
configuration on the node’s topology database at any time.
All
Enabled Enabling
The node has been enabled as a gateway node. During this
period, do not perform any configuration on the topology
database. Once the database’s enabling process is
finished, the operational state becomes ENABLED, and
the topology can be configured.
No
Disabled Disabling
The gateway node is going through the disabling process.
During this period, do not perform any configuration on
the topology database. Once the database’s disabling
process is finished, the operational state becomes
DISABLED, and the node can be enabled.
No
Disabled Disabled
The node is a non-gateway node. You can perform
configuration on the node’s topology database at any time.
No
Enabled Full
The node is functioning as a gateway. However, the node’s
topology database is full, and can not accept new entries.
All operations are still permitted on the topology
database.
Yes
Disabled Full
The node is functioning as a non-gateway node. However,
the node’s topology database is full, and can not accept
new entries. All operations are still permitted on the
topology database.
Yes
