Troubleshooting Trunking

Problem: I’ve created a Trunking service but cannot connect to the ATM network.

Solution: Use the following solutions:

￿Verify that the Trunking service has been created, admin status is enabled, and protocol state is ‘active’.

/ATM/SHOW/trunk <trunk id> /ATM/CONFIG/ENABLE/trunk <trunk id>

￿If using SVC connections, ensure that the ATM port is configured for SVC mode and ILMI is enabled. By default, the ATM port is set to ‘PVC’ mode and ILMI is disabled.

/ATM/CONFIG/MODIFY> port

￿If using SVC connections, ensure that the ATM port is configured for SVC mode. By default, the ATM port is set to ‘PVC’ mode.

/ATM/CONFIG/MODIFY> port

￿If using SVC connections, ensure that you are using the same UNI signaling version as that of the connected ATM switch.

/ATM/CONFIG/MODIFY >port

￿If using SVC connections, verify the following:

–Port configured as SVC, ILMI enabled, UNI version is correct.

/ATM/CONFIG/MODIFY >port

–Correct ATM address of destination switch. The last 2 selector bytes needs to be configured as follows:

Example: xxx62

‘xxx’ denotes the ATM address defined on the switch. Do a ‘vap’ to find out what it is.

‘6’ is a reserved identifier for Trunking.

‘2’ identifies the Trunk index configured on the destination switch. Ensure the correct Trunk index is mapped to the switch you are trying to connect to.

–Verify signaling and ILMI status is ‘up’.

/ATM/SHOW >port
