Can the two Eth ports on a ZoneDirector be used for Load Balancing?
SummaryCan the two Eth ports on a ZoneDirector be used for Load Balancing / link aggregation?
QuestionCan the two Eth ports on a ZoneDirector be used for Load Balancing?
Customer EnvironmentZoneDirector and 2+ customer switches
Root CauseCustomers see two GigE ports on ZoneDirector and wonder if they can be combined for increased throughput.
ResolutionThe two Ethernet ports on a ZoneDirector are each 1gig capable, but the two Physical interfaces are one Logical
interface to the ZoneDirector.
You can connect each ZD interface to a separate network switch, but Spanning Tree should block one of the switch
port paths to prevent the ZD MAC address from being seen on it's other interface, forming a loop.
This provides High Availability for uptime purposes, in the event that a cable/interface/switch went bad or went down,
but we cannot transmit/receive traffic over both ZD interfaces simultaneously (Load Balancing / Link Aggregation).
