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

Fault-tolerant design is an important dmlt of Multi-Link Trunking technology. Views Read Edit View history. The edge switch should be setup as an MLT.

By ensuring all devices have SMLT connections to the aggregation switches, traffic never needs to traverse the IST and the total forwarding capacity of the switches in the cluster is also aggregated.
From Wikipedia, the free encyclopedia. CP-Limit will shutdown the link to try and protect the core network. SLPP is a protocol design to detect edge switches that are not configured properly. Please try again in a few minutes. The commands avyaa today can be easily adapted to cover a stack instead of a single unit, simply by prefacing the port numbers with the unit number i.

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 smly time- and loss-sensitive applications such as voice and video.

As was mentioned, it is much more common to see a stack of switches at the edge rather than single switch, for obvious reasons.
Take the following scenario with SMLT: Hi Mikail, This comment is kinda off-topic for this specific blog post.

What would happen if the edge switch was accidentally factory reset with both smt still connected? Distributed multi-link trunking DMLT or distributed MLT is a proprietary computer networking protocol designed by Nortel Networksand now owned by extreme networks[7] used to load balance the network traffic across connections and also across multiple switches or modules in a chassis.
Also, is it possible to spread the load over all uplinks, utilizing both core swicthes in order to spread the load? In other projects Wikimedia Commons. Retrieved July 10, 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.
VRRP with Backup Master solves the problem by allowing routing through either of the core switches so the above scenario does not occur. Enter your username or e-mail address to receive an e-mail with instructions to reset your password.

VLACP is strictly a heart-beat based end-to-end detection mechanism possessing no link aggregation capabilities. Now set it up using the following commands: R-SMLT takes care of packet forwarding in core router failures and works with any of the following protocol types: By continuing to use slmt website, you agree to their use. Leave a Reply Cancel reply Your email address will not be avayz. ERS config -if exit.
The core configuration is finished! This site uses cookies. The layer 3 configuration of the core is next. These will all be covered in detail in other posts. Ok, I will try it then.

The network will utilize Nortel’s SMLT Split Multi-Link Trunking technology, which provides exceptional resiliency to ensure voice, video and other applications stay connected despite link, switch or site equipment failures. The Rx thresholds are staggered between the two switches, so the primary switch disables its uplinks if a loop occurs.
