Retrieved from ” https: The commands learned 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. Our configuration is quite similiar to yours.

VLACP parameters must be configured the same on both ends of the link to achieve connectivity. SLPP is a protocol design avaga detect edge switches that are not configured properly.

The edge switch should be setup as an MLT. This command will discard any non If you accept or continue browsing you agree to our cookie policy.

What is a MLT, DMLT, SMLT, SLT or IST?

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. Login to the community No account yet? 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 user traffic traversing the IST is minimized to a large degree but it can occur on occasion. Company Private Only you and moderators can see this information. If only one end is split, the topology is referred to as an SMLT triangle. We use cookies to ensure that we give you the best experience on our website. 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.

MultiLink Trunking MLT is a point-to-point connection that aggregates multiple ports to logically act like a single port, with the aggregated bandwidth. ERS config vlan create 30 name mgmt type port. ERS config mlt 1 enable. This command will enable tagging to make the port an ERS config vlacp macaddress 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: You can check out the article for information on algorithms and their working.

Yes, you are correct. Note – These features should never be enabled on the uplinks MLT, in this case ports 1, 2, 3, and 4 from the edge to the core: Retrieved July 10, VLACP is strictly a heart-beat based end-to-end detection mechanism possessing no link aggregation capabilities.

The split may be at one or at both ends of the MLT. This is obviously not an optimal traffic path. Thanks for any insight. Cookie policy We use cookies to enhance and personalize your experience. ERS config vlan members remove 1 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.
