MLT or DMLT

Enable a MultiLink Trunk (MLT) or a Distributed MultiLink Trunking (DMLT) to help you detect

connectivity issues. You can use the following ACLI commands to manage an MLT or DMLT:

• Use the show mlt shutdown-ports-on-disable command to verify the status of

an MLT or DMLT.

• Use the no mlt shutdown-ports-on-disable enable command to disable

member links of an MLT or DMLT on the switch, when you need to perform MLT or DMLT

maintenance. All member links are disabled except the Destination Lookup Failure (DLF)

link.

• Use the mlt shutdown-ports-on-disable enable command to enable member

links of an MLT or DMLT. Configuring the switch to automatically enable all member links

in a trunk at once significantly reduces the risk of introducing loops and other problems

to the network.

• Avaya recommends that you use the mlt enable {1–32} command to ensure that

MLT is fully functional and that all links are enabled.

Simple Network Management Protocol (SNMP) traps can be useful troubleshooting tools. With

the VSP 7000 series switches You can enable or disable SNMP traps for the following features:

• Rapid Spanning Tree Protocol (RSTP)

For detailed information about configuring SNMP traps, see Avaya Virtual Services Platform

7000 Series Configuration Security (NN47202-501).
