Problems with Connections Between Switches
No Connection Between Two Workgroup Switches in the Same ATM Cluster
Steps to Take:
1. Use the SHOW PORT command to:
Ÿ Make sure that the ATM media port at each end of the connection is configured with an SSI interface. If not,
use the SET PORT command and specify
SSI as the interface parameter.
Ÿ Make sure that the the status of each port is OKAY . If not, follow the procedure described in “Problems with
ATM Ports Attached to ATM Devices” on page 162.
2. Make sure the bandwidth allocated is the same on both ends.
3. Contact your IBM service representative.
No Connection Between Two Clusters in the Same ATM Subnetwork
Steps to Take:
1. Use the SHOW PORT command to:
Ÿ
Make sure that the ATM media port at each end of the connection is configured with an NNI interface. If not,
use the SET PORT command and specify
NNI
as the interface parameter.
Ÿ Make sure that the status of each port is OKAY . If not, follow the procedure described in “Problems with ATM
Ports Attached to ATM Devices” on page 162.
2. Use the SHOW DEVICE command to:
Ÿ Make sure that the ATM address of each workgroup switch in the subnetwork is configured with the same
Routing Domain number (RDN).
Ÿ Make sure that each boundary switch is configured with a different ATM Cluster number (ACN).
3. Use the SHOW LOGICAL LINK command to make sure that the logical link settings of the ATM media port on
each boundary switch are correctly configured.
4. Contact your IBM service representative.
No Connection Between Two ATM Subnetworks
Steps to Take:
1. Use the SHOW PORT command to:
Ÿ Make sure that the ATM media port at each end of the connection is configured with an NNI interface. If not,
use the SET PORT command and specify
NNI as the interface parameter.
Ÿ
Make sure that the status of each port is
OKAY
. If not, follow the procedure described in “Problems with ATM
Ports Attached to ATM Devices” on page 162.
2. Use the SHOW LOGICAL LINK command to make sure that the logical link settings of the ATM media port on
each boundary switch are correctly configured.
3. Use the SHOW DEVICE command to make sure that the network prefixes and logical ATM cluster number are
correctly configured for the boundary switch in each subnetwork.
4. If the connection is over a VP service provider, refer to your contract with the VP service provider to make sure
that certain settings (for example, VP identifier) are correct.
5. Contact your IBM service representative.
