The edge switch should be setup as an MLT. You can refer to this post for additional details regarding how to configure the edge switch. This command will enable tagging to make the port an This command will discard any non This can be a valuable defense measure in protecting your network.

What would happen if the edge switch was accidentally factory reset with both uplinks still connected? A loop would result, however, with this feature all frames from the edge switch will be discarded until the switch is reconfigured. This command will enable CP-Limit to protect the core network from too many Multicast or broadcast packets flooding the link.

CP-Limit will shutdown the link to try and protect the core network. This is just one of many defense mechanisms available to help protect your network. This command will enable DiffServ Layer 3 QoS on the switch port and set it for Trusted , so the switch will honor all DiffServ marked packets and give those packets the appropriate priority and queuing. This is a best practice recommendation by Avaya to help reduce the ARP broadcast storms that can result when the FDB table expires a large number of entries which then in turn causes them to be removed from the ARP table causing the switch to re-ARP for them.

You should repeat the commands above in Step 2 on both Avaya Ethernet Routing Switch s, substitute the appropriate IP address and ports. You might also want to read these other posts Some documents infer the IST is a routed link, others that it is a switched link.

Some say no user traffic is sent across IST, but then how would you get redundant connectivity. The user traffic traversing the IST is minimized to a large degree but it can occur on occasion. In the event of a link failure to a closet then a large portion of traffic may need to traverse the IST to get back to resources servers, etc physically attached to that core switch. Traffic is split across both links using an algorithm that hashes the source and destination MAC addresses this way the same conversation always flows over the same path.

SLPP is a protocol design to detect edge switches that are not configured properly. 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. We are currently installing a new datacenter and needed to aggregate the link black fiber between our two sites. Our configuration is quite similiar to yours.

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. Why would a virtual machine route its traffic via one of the Core switches instead of the other? Also, is it possible to spread the load over all uplinks, utilizing both core swicthes in order to spread the load? The intent is that all the packets from a single conversation should flow over the same path, avoiding out of order frames, etc.

Thanks for any insight. Thanks for the comment! Thank you for this post, it helps me a lot to validate my own configuration. 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.

Hi Mikail, This comment is kinda off-topic for this specific blog post. 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

Multi-link trunking MLT is a link aggregation technology developed at Nortel in It allows grouping several physical Ethernet links into one logical Ethernet link to provide fault-tolerance and high-speed links between routers, switches, and servers. 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. This produces server to switch or switch to switch connections that are up to 8 times faster. Fault-tolerant design is an important aspect of Multi-Link Trunking technology. Should any one or more than one link fail, the MLT technology will automatically redistribute traffic across the remaining links. This automatic redistribution is accomplished in less than half a second typically less than millisecond [2] so no outage is noticed by end users.
