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 parameters must be configured the same on both ends of the link to achieve connectivity. USFite, Jr.

Nortel/Avaya’s MLT,DMLT,IST,SMLT,SLT & RSMLT – Network Architect

The core configuration is finished! DSMLT allows the ports in a trunk 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 one card in a chassis fails.

CP-Limit will shutdown the link to try and protect the core network. SLPP is designed to detect that loop and shutdown only 1 on the uplinks thereby preserving connectivity to the closet while protecting the network from collapse. The only requirement is that IEEE Learn how your comment data is processed.

Depending on the specific routing protocol, this convergence time can cause network sm,t ranging from seconds to minutes. Enter your username or e-mail address to receive an e-mail with instructions to reset your password.

What is a MLT, DMLT, SMLT, SLT or IST?

Here is a diagram of the topology for this implementation:. From Wikipedia, the free encyclopedia. Ok, I will try it then. ERS config vlan members remove 1 By using this site, you agree to the Terms of Use and Privacy Policy.

ERS config -if ip address Take the following scenario with SMLT: Company Private Only you and moderators can see this information. Please try again in a few minutes.

SLT is best suited for large-scale deployments of edge switches from a single switch cluster.

ERS config vlan ports 1,2,3,4 tagging tagAll filter-untagged-frame enable. The basic configuration of the core is done! A loop would result, however, with this feature all frames from the edge switch will be discarded until the switch is reconfigured.

VLACP is strictly a heart-beat based end-to-end detection mechanism possessing no link aggregation capabilities. 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 avaua or switch failure.

ERS config interface vlan ERS config -if spanning-tree bpdu -filtering enable. United States Patent and Trademark Office. If this still does not resolve the loop, the secondary switch will disable its uplinks, isolating them and preventing the rest of the network from being affected by the loop: Using this technology allows or enables the use of several links from 2 up to 8 and combined them to create increased bandwidth and several fail-over paths.


In many cases, core network convergence time after a failure is dependent on the length of time a routing protocol requires to successfully converge change or re-route traffic around the fault.

MLT on Exos to work with Avaya MLT/SMLT

Thank you for this post, it helps me a lot to validate my own configuration. Sorry, we’re still checking this file’s contents to make sure it’s safe to download.

In general the failure of any one component results in a traffic disruption lasting less than half a second normal less than millisecond [2] [3] making SMLT appropriate in environments running time- and loss-sensitive applications such as voice and video. ERS config vlan create 20 name data2 type port. ERS config vlan members add 30 ,47, R-SMLT takes care of packet forwarding in core router failures and works with any of the following protocol types: Thanks for the comment!

It doesn’t really matter for SMLT by itself, but to have a better traffic load-balancing from that switch, pick what you need. This can be a valuable defense measure in protecting your network. Retrieved from ” https:
