More than one S-Ring pair can be selected and more than one S-Ring can be
defined per switch. Note – the mP62 as well as the ES42 switches support LLL and can
participate in S-Ring as an access switch

to a single link failure but also for one device failing on the network

– an incorrect LACP connection scheme for Magnum 6K family of switches. All
LACP trunk ports must be on the same module and cannot span different modules.

– In this figure, even though the connections are from one module to another, this is
still not a valid configuration (for LACP using 4 ports) as the trunk group belongs to two
different VLANs.

-
In the figure above, there is no common VLAN between the two sets of ports, so
packets from one VLAN to another cannot be forwarded. There should be at least one
VLAN common between the two switches and the LACP port groups.

– This configuration is similar to the previous configuration, except there is a
common VLAN (VLAN 1) between the two sets of LACP ports. This is a valid
configuration.

– In the architecture above, using RSTP and LACP allows multiple switches to be
configured together in a meshed redundant link architecture. First define the RSTP
configuration on the switches. Then define the LACP ports. Then finally connect the ports
together to form the meshed redundant link topology as shown above.

– LACP, along with RSTP/STP brings redundancy to the network core or
backbone. Using this reliable core with a dual-homed edge switch brings reliability and
redundancy to the edge of the network
