Connecting Physical Cables
Single Chassis Systems
It is not necessary to connect Sync ports in a single Chassis system. This is because communication between SGMs are handled internally by the Chassis infrastructure.
Dual Chassis system with a Cross cable
eth1-Sync in chassis1 connects to eth1-Sync in chassis2.eth2-Sync in chassis1 is connects to eth2-Sync in chassis2.
Dual Chassis system with the Sync Bond on the switch
- Configure all ports in the switch in the same VLAN broadcast domain.
- Each switch configures a bond for its chassis.
Dual chassis system without a Sync Bond on a the switch
eth1-Sync communicates over VLAN X.eth2-Sync communicates over VLAN Y.- Configure switches for VLAN access on each related port.
Configure "Link State Tracking" (Cisco), or an equivalent mechanism, so that Sync port peers go Down on both Chassis after a failure on one Chassis. If you do not do this, and the Sync port fails on one Chassis, the related peer Sync port will stay UP.
