Use this command to configure load-balance mode on all HiGig™ trunks across the units in a stacking topology. Prior to Dynamic Load Balancing (DLB), this command supported load-balance IDs 1 to 7. Load-balance IDs 8, 9, and 10 support DLB on LAG as listed in the following table.
| Default | 3 |
| Format | trunk-hashmode <id>] |
| Mode | Stack Config |
| Parameter | Description |
|---|---|
| 1 | Source MAC, VLAN, EtherType, and incoming port associated with the packet. |
| 2 | Destination MAC, VLAN, EtherType, and incoming port associated with the packet. |
| 3 | Source/Destination MAC, VLAN, EtherType, and incoming port associated with the packet. |
| 4 | Source IP and Source TCP/UDP fields of the packet. |
| 5 | Destination IP and Destination TCP/UDP Port fields of the packet. |
| 6 | Source/Destination IP and source/destination TCP/UDP Port fields of the packet. |
| 7 | Enhanced hashing mode. |
| 8 | DLB Spray Mode. |
| 9 | DLB Eligibility Mode. |
| 10 | DLB Fixed Assignment Mode. |
Note:
- This command works at a system level. HiGig trunks are formed dynamically when more than one stack links are connected between two stackable switches. This command applies DLB mode to *all* the HiGig trunks that are available across all the units. If a new HiGig trunk is formed later or a new member unit joins the stack over a HiGig trunk, this command is applied to those newly formed HiGig trunks as well.
- In most platforms, DLB can only be configured either in HiGig trunk (for stacking) or for LAG load-balance. They cannot be configured together at the same time. If LAG is configured with DLB, trunk-hashmode cannot be configured with DLB for stacking and vice-versa.
