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 avaga 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. Next create the MLT at the edge: Sign up Already have an account? This automatic redistribution is accomplished in less than half a second typically less than millisecond [1] so no outage is noticed by end users.

ERS config -if spanning-tree bpdu -filtering enable. Learn more about our cookies. The core configuration is finished! USFite, Jr. Take the following scenario with SMLT: This command will enable CP-Limit to protect the core network from too many Multicast or amlt packets flooding the link.

Wikimedia Commons has media related to Nortel. 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 remove 1 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. An edge switch uses the SMLT to send out a packet that needs to be routed, and that packet due to the traffic hashing algorithms of link aggregation protocols has a small to large chance of hitting the switch in the cluster that is not the VRRP master, so the core switch that received the packet must forward it across the IST link to the other agaya switch that is designated as the master.

Here is a diagram of the topology for this implementation:. ERS config vlan ports 1,2,3,4 tagging tagAll filter-untagged-frame enable.

You are commenting using avayz Twitter account. To include ports as trunk group members of an MLT, you must statically configure the ports. CP-Limit will shutdown the link to try and protect the core network. ERS sm,t -if spanning-tree learning fast. This can be a valuable defense measure in protecting your network.

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: ERS config -if spanning-tree bpdu -filtering timeout 0.

What would happen if the edge switch was accidentally factory reset with avxya uplinks still connected?

In a network using SMLT, it is often no longer necessary to run a spanning tree protocol of any kind since there are no logical bridging loops introduced by the presence of the IST. MultiLink Trunking MLT is a point-to-point connection that aggregates multiple ports to logically act like a single port, with the aggregated bandwidth.

You should repeat the commands above in Step 2 on both Avaya Ethernet Routing Switch s, substitute the appropriate IP address and ports.
