Symptoms: A router may reject the creation of virtual Token Ring interface with any interface
number from 0 to 9 and allow only the creation of virtual Token Ring interface with an interface
number that is equal to or greater than 10.

Symptoms: When DLSw Ethernet Redundancy is configured, circuits may be established through
the wrong switch.
the wrong switch.
Conditions: This symptom is observed in the following configuration:
–
Clients are connecting to MAC A.
–
Mapping statements are configured so that Switch 1 has a mapping of MAC A = MAC A and
Switch 2 has a mapping of MAC B = MAC A.
Switch 2 has a mapping of MAC B = MAC A.
The output of the show dlsw transparent map shows that Switch 1 has the active mapping and that
Switch 2 has the passive mapping. All circuits should be established on Switch 1, but instead they
are established on switch 2.
Switch 2 has the passive mapping. All circuits should be established on Switch 1, but instead they
are established on switch 2.
The outputs of the show dlsw trans neighbor and show dlsw trans map commands show correct
information, but the output of the show dlsw cir cache command shows state “negative” on Switch 1
and state “positive” on Switch 2.
