FIGURE 94 – More than one S-Ring pair can be selected and more than one S-Ring can bedefined per switch. Note – the mP62 as well as the ES42 switches support LLL and canparticipate in S-Ring as an access switch .................................................................................. 180F IGURE 95 – Activating S-Ring on the switch .................................................................................... 182FIGURE 96 – S-Ring configuration commands for root switch .............................................................. 184FIGURE 97 – Link Loss Learn (LLL) setup. Setup LLL on ports connected to other switchesparticipating in S-Ring ............................................................................................................ 185FIGURE 98 – Dual-homing using ESD42 switch and Magnum 6K family of switches. In case ofa connectivity break – the connection switches to the standby path or standby link ..................... 188FIGURE 99 – Dual-homing using Magnum 6K family of switches. Note the end device (videosurveillance camera) can be powered using PoE options on Magnum 6K family of switches.In case of a connectivity break – the connection switches to the standby path or standbylink ........................................................................................................................................ 188FIGURE 100 – Using S-Ring and dual-homing, it is possible to build networks resilient not onlyto a single link failure but also for one device failing on the network .......................................... 189F IGURE 101 – configuring dual-homing ............................................................................................... 191FIGURE 102 – Some valid LACP configurations................................................................................ 195FIGURE 103 – an incorrect LACP connection scheme for Magnum 6K family of switches. AllLACP trunk ports must be on the same module and cannot span different modules. ................. 195FIGURE 104 – In this figure, even though the connections are from one module to another, this isstill not a valid configuration (for LACP using 4 ports) as the trunk group belongs to twodifferent VLANs. .................................................................................................................. 195FIGURE 105 - In the figure above, there is no common VLAN between the two sets of ports, sopackets from one VLAN to another cannot be forwarded. There should be at least oneVLAN common between the two switches and the LACP port groups. ................................... 196FIGURE 106 – This configuration is similar to the previous configuration, except there is acommon VLAN (VLAN 1) between the two sets of LACP ports. This is a validconfiguration............................................................................................................................ 197FIGURE 107 – In the architecture above, using RSTP and LACP allows multiple switches to beconfigured together in a meshed redundant link architecture. First define the RSTPconfiguration on the switches. Then define the LACP ports. Then finally connect the portstogether to form the meshed redundant link topology as shown above. ......................................... 197FIGURE 108 – LACP, along with RSTP/STP brings redundancy to the network core orbackbone. Using this reliable core with a dual-homed edge switch brings reliability andredundancy to the edge of the network ....................................................................................... 198FIGURE 109 – This architecture is not recommended............................................................................ 199F IGURE 110 – Creating a reliable infrastructure using wireless bridges (between two facilities) andLACP. “A” indicates a Wi-Fi wireless Bridge or other wireless Bridges. ................................. 200FIGURE 111 – Configuring LACP .................................................................................................... 202xv |
