Problem
Probable Cause
Possible Solution
An unexpected
volume of control
frames is present.
Configuration is
incorrect.
Check the menu item “Graphing Client
Performance Information” to get
information about the control frames
and to change the configuration
accordingly. For example, if the OUT
ARP requests have a high volume, you
probably need to change the ARP
response time.
The device must
be taken offline
for maintenance
purposes.
Possible effects will take
place on ELANs.
Check the ATM-VLAN catalog from
the fabric map to list all the ELAN
components residing on a device.
The PNNI node
does not appear
on the topology
map.
The PNNI node is not
enabled.
Use CiscoView or the CLI to verify
that the PNNI node (node index = 1) is
enabled. Then select the LightStream
1010 switch that contains the node,
and rediscover the device.
The PNNI node is
isolated from the
PNNI network.
The ANI server did not
find a PNNI link for this
node during the previous
discovery cycle.
Select the PNNI node from the PNNI
topology map. Then check to see if the
level of the PNNI node is the same as
the other nodes. Also check to see if
any interfaces for this node are
configured to PNNI.
Note:
If the node level and interface
information is correct, you need to
rediscover the device. The PNNI link
takes approximately 2 to 3 minutes to
synchronize with the neighboring
nodes, and the ANI server might not
have found a PNNI link from this node
in the previous discovery cycle.
Troubleshooting TrafficDirector
In some cases, the TrafficDirector environment does not work as you would expect. This subsection
includes tips for troubleshooting your TrafficDirector environment. It explains the following:
