Troubleshooting General Issues

The Cisco SME naming convention includes alphanumeric, dash, and underscore characters. Other types
of characters will cause problems in the cluster configuration.

Troubleshooting Scenarios

The following scenarios are described in this section:

If DNS is not configured on all switches in a cluster
You can use sme.useIP for IP address or name selection when DNS is not configured on all switches in
a cluster.
sme.useIP can be used in smeserver.properties to enable the use of IP addresses instead of switch names.
By default sme.useIP is set to false and DNS names will be used. When DNS is not configured, Fabric
Manager Server cannot resolve the switch names.
When sme.useIP is set to true, Fabric Manager Server uses an IP address to communicate with switch in
the cluster using SSH. All switches are added to the cluster with an IP address. When you add a local
switch, the switch name is used if the name server is configured on the switch otherwise the IP address
is used.
When sme.useIP is false, Fabric Manager Server will use the switch name to select interfaces. All the
switches added to the clusters will be identified with names. A name server is required for this type of
configuration. Otherwise, switches will not be able to communicate with other switches to form the
cluster and Fabric Manager Server will not be able to resolve the switch name.
