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

What should the algorithm and distribution-mode be? This is just one of many defense mechanisms available to help protect your network. Create an account Login with your Extreme Portal account or. VRRP with Backup Master solves the problem by allowing routing through smmlt of the core switches so the above scenario does not occur. ERS config mlt 1 name toCore member 1,2,3,4 learning disable. This command will enable tagging to make the port an It allows grouping several physical Ethernet links into slt logical Ethernet link to provide fault-tolerance and high-speed links between routers, switches, and servers.

Ok, I will try it then. Thanks for any insight.

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

For real-world network traffic this generally results in an effective bandwidth for the logical link equal to the sum of the bandwidth of the individual physical links. ERS config vlan members add 20 avzya, The core configuration is finished! CP-Limit will shutdown the link to try and protect the core network. Yes, you are correct. The IST ports are also tagged trunks.

This can be a valuable defense measure in protecting your network. USFite, Jr. 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. The two switches between which the SMLT is split are known as aggregation switches and form a logical cluster which appears to the other end of the SMLT link as a single switch.

Using this technology allows or enables the use of several avaha from 2 up to 8 and combined them to create increased bandwidth and several fail-over paths. This file cannot be downloaded Sorry, our virus scanner detected that this file isn’t safe to download.

The user traffic traversing the IST is minimized to a large degree but it can occur on occasion. Learn how your comment data is processed. BPDU Filtering will help to keep devices that could be connected to the network from causing root bridge re-elections and topology flapping.

Here is a diagram of the topology for this implementation: We use cookies to ensure that we give you slt best experience on our website. Should any one switch, port, or more than one link fail, the DSMLT technology will automatically redistribute traffic across the remaining links.

Multi-link trunking – Wikipedia

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.

From Wikipedia, the free encyclopedia. You are commenting using your Twitter account. ERS config s,lt spanning-tree learning fast.

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. Some documents infer the IST is a routed link, others that it is a switched link.

Our configuration is quite similiar to yours. The Rx thresholds are staggered between the two switches, so the primary switch disables its uplinks if a loop occurs. That way, it will default to L2 address for hashing. This eliminates the need for spanning tree reconvergence or root-bridge failovers in failure scenarios which causes interruptions in network traffic longer than time-sensitive applications are able to cater for.

Hi, you are correct. VLACP parameters must be configured the same on both ends of the link to achieve connectivity. This site uses cookies. Depending on the specific routing protocol, this convergence time can cause network interruptions ranging from seconds to minutes.

Grouping multiple ports into a logical link provides a higher aggregate on a switch-to-switch avaay switch-to-server application. ERS config vlan create 10 name data1 type port. Ssmlt config -if spanning-tree bpdu -filtering enable. 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.

You can check out the article for information on algorithms and their working.

ERS config vlan create 20 name data2 type port. You should repeat the commands above in Step 2 on both Avaya Ethernet Routing Switch s, substitute the appropriate IP address and ports. This command will enable CP-Limit to protect the core network from too many Multicast or broadcast packets flooding the link.
