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

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. Some say no user traffic is sent across IST, but then how would you get redundant connectivity.

Retrieved 3 Sep To find out more, including how to control cookies, see here: You are commenting using your WordPress. The split may be at one or at both ends of the MLT.

R-SMLT takes care of packet forwarding in core router failures sm,t works with any of the smot protocol types: This design provides excellent bandwidth and redundancy, and is capable of supporting approximately small campus to medium campus users when adding switches or stacks at the edge for scalability. 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.

Multi-link trunking – Wikipedia

Send Back to overview. VRRP with Backup Master solves the problem by allowing routing through either of the core switches so the above scenario does not occur. We are currently installing a new datacenter and needed to aggregate the link black fiber between our two sites. What would happen if the edge switch was accidentally factory reset with both zvaya still connected?

You can check out the article for information on algorithms and their working. A general limitation of standard Ssmlt is that all the physical ports in the link aggregation group must reside on the same switch.

If both ends of the link are split, the resulting topology is referred to as an amlt square” when there is no cross-connect between diagonally opposite aggregation switches, or an “SMLT mesh” when each aggregation switch has a SMLT connection with both aggregation switches in the other pair.

Avaya Split MultiLink Trunking (SMLT) Layer 2 Trunking

ERS config vlan members add 30 ,47, What should the algorithm and distribution-mode be? Hi Micheal, i just have a problem, 2 ers working with smlt but, second ers ip address renewing but very slow First main system v3.

SLPP is a protocol design to detect edge switches that are not configured properly. Leave a Reply Cancel reply Your email address will not be published.

Now for the edge configuration. For each packet that needs to be transmitted, one of the physical links is selected based on a load-balancing algorithm usually involving a hash function operating on the source and destination Media Access Control MAC address information.

Look up MLT in Wiktionary, the free dictionary. DMLT allows the ports in a trunk MLT to span multiple avzya 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.

Avaya Split MultiLink Trunking (SMLT) Layer 2 Trunking

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.

Link aggregation or MLT allows multiple physical network links between two network switches and another device which smlr 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.
