ATM Connection Problems
No Connection between Two Switches in the Same Peer Group
Steps to Take:
1. Use the SHOW PORT VERBOSE command to:
Make sure that the media port at each end of the connection is configured with a PNNI interface. If not, use
the SET PORT command and specify
PNNI
as the interface parameter.
Make sure that the status of each port is
UP
. If not, follow the procedure described in the
IBM 8265 Media
Module Reference Guide, SA33-0459.
2. Make sure that the bandwidth specified is the same at both ends of the trunk.
If you have not specified a bandwidth, make sure that the bandwidth of of the module is exceeded.
3. Contact your IBM service representative.
No Connection Between Two ATM Switches in Different Peer Groups
Steps to Take:
1. Use the SHOW PORT command to:
Make sure that the media port at each end of the connection is configured with an IISP interface. If not, use
the SET PORT command and specify
IISP
as the interface parameter.
Make sure that the status of each port is
UP
. If not, follow the procedure described in the
IBM 8265 Media
Module Reference Guide, SA33-0459.
2. Use the SHOW REACHABLE_ADDRESS command to:
Make sure that the ATM address of each switch is configured with a reachable address of the other one.
3. Use the SHOW PORT command to make sure that the VPI of the media ports on each boundary switch are
correctly configured.
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.
Cannot create a PVC between two 8265s located in different peer groups.
Explanation:
This is normal. The 8265 does not allow the creation of PVCs over network-to-network (IISP) links.
You have created two different PVCs, each one ending at the IISP port.
Note: Make sure that the VPI used by the PVC on the IISP port corresponds to the one of the logical link defined
on that port.
