AVAYA SMLT PDF

An SMLT/SLT is Avaya’s proprietary equivalent to Cisco’s Virtual PortChannel feature. When do you use one over the other, SMLT or SLT?. It was recently pointed out to me that I had never written a post documenting how to configure SMLT to a edge/closet switch. While there are. Multi-link trunking (MLT) is a link aggregation port trunking technology developed at Nortel in . SMLT is supported within the following Avaya Ethernet Routing Switch (ERS) and Virtual Services Platform (VSP) Product Families: ERS

VLACP is an important feature that can disable links to protect against a situation where a switch might smot link connectivity but cannot pass traffic due to switch lockups.

A general limitation of standard link aggregation, MLT or EtherChannel is that all the physical ports in the link aggregation group must reside on the same switch.

Here is a diagram of the topology for this implementation:. Hi, Can you explain to me how the avaya routing algorithm works when you have 2 x switches in a stack using SMLT connected to 2 x ERS using 4 x 10gbps fibre connections.

You are commenting using your Twitter account. ERS config vlan members remove 1 The intent is that all the packets from a agaya conversation should flow over the same path, avoiding out of order frames, etc.

If LACP is not needed, your command is good. The basic configuration of the core is done! ERS config -if spanning-tree learning fast.

ERS config interface FastEthernet Retrieved from ” https: Already have an account? Retrieved July 10, DMLT allows the ports in a trunk MLT to span multiple units of a stack of switches or to span multiple cards in a chassis, preventing network outages when one switch in a stack fails or a card in a chassis fails.

ERS config vlan members add 20VLACP parameters must be configured the same on both ends of the link to achieve connectivity. Link aggregation or MLT allows multiple physical network links between two network switches and another device which could be another switch or a network device such as a server to be treated as a single logical link and load balance the traffic across all available links.

Next create the MLT at the edge: Login to the community No account yet? VRRP with Backup Master solves the problem by allowing routing through either of the core switches so the above scenario does not occur.

What should the algorithm and distribution-mode be? United States Patent and Trademark Office. A general limitation of standard MLT is that all the physical ports in the link aggregation group avata reside on the same switch. You can check out the article for information on algorithms and their working. If you need LACP, just add that keyword at the end. If only one end is split, the topology is referred to as an SMLT sjlt.

The use of SMLT not only allows traffic to be load-balanced across all the links in an aggregation group but also allows traffic to be redistributed very quickly in the event of link or switch failure. ERS config mlt 1 name toCore member 1,2,3,4 learning disable. Hi Mikail, This comment is kinda off-topic for this specific blog post. ERS config vlan members add 10Take the following scenario with SMLT: The two core switches use the IST to share L2 learned information, so they appear as one.
