What Are LAG Specifications of CE Series Switches?

What Are LAG Specifications of CE Series Switches?

CE6870EI, CE6875EI and CE12800 Series Switches

Run the assign forward eth-trunk mode { 128 | 256 | 512 | 1024 } command in the system view to set the number of LAGs supported by the switch. By default, a maximum of 512 LAGs can be configured on the switch.
  • When 128 is specified, the switch allows a maximum of 128 LAGs and each LAG supports a maximum of 128 member interfaces. (Starting from V200R003C00, only the CE12800 supports 128.)
  • When 256 is specified, the switch allows a maximum of 256 LAGs and each LAG supports a maximum of 64 member interfaces.
  • When 512 is specified, the switch allows a maximum of 512 LAGs and each LAG supports a maximum of 32 member interfaces.
  • When 1024 is specified, the switch allows a maximum of 1024 LAGs and each LAG supports a maximum of 16 member interfaces.

CE12800E Series Switches

  • CE12800E configured with ED-E, EG-E, or EGA-E series cards: The CE12800E allows a maximum of 1024 LAGs and each LAG supports a maximum of 64 member interfaces.

  • The CE16800 allows a maximum of 1024 LAGs and each LAG supports a maximum of 128 member interfaces.
  • CE12800E configured with FD-X series cards: Run the assign forward eth-trunk mode { 64 | 128 | 256 | 512 | 1024 } command in the system view to set the number of LAGs supported by the switch. By default, a maximum of 128 LAGs can be configured on the switch.
    • When 64 is specified, the switch allows a maximum of 64 LAGs and each LAG supports a maximum of 32 member interfaces.
    • When 128 is specified, the switch allows a maximum of 128 LAGs and each LAG supports a maximum of 16 member interfaces.
    • When 256 is specified, the switch allows a maximum of 256 LAGs and each LAG supports a maximum of 8 member interfaces.
    • When 512 is specified, the switch allows a maximum of 512 LAGs and each LAG supports a maximum of 4 member interfaces.
    • When 1024 is specified, the switch allows a maximum of 1024 LAGs and each LAG supports a maximum of 2 member interfaces.

CE8800, CE7800, CE6800, and CE5800 Series Switches (Excluding CE6870EI and CE6875EI)

The CE5810EI allows a maximum of 128 LAGs and each LAG supports a maximum of eight member interfaces. The CE5880EI and CE6880EI allow a maximum of 1024 LAGs and each LAG supports a maximum of 128 member interfaces. Table 22-61 lists the LAG specifications supported by other switch models.

Version

Configurable Specification

Default Value

V100R005C00

On the CE6810LI, run the assign forward eth-trunk mode { 24 | 48 | 96 } command in the system view.

On other models except the CE6810LI, run the assign forward eth-trunk mode { 64 | 128 } command in the system view.

CE6810LI: 48

Other models except the CE6810LI: 128

V100R005C10 and later versions

Run the assign forward eth-trunk mode { 64 | 128 | 256 | 512 | 1024 } command in the system view.

128

After the assign forward eth-trunk mode command is used to change the number of LAGs supported by the switch, restart the switch to make the configuration take effect.

CE6810LI of V100R005C00:
  • When 24 is specified, the switch allows a maximum of 24 LAGs and each LAG supports a maximum of 32 member interfaces.
  • When 48 is specified, the switch allows a maximum of 48 LAGs and each LAG supports a maximum of 16 member interfaces.
  • When 96 is specified, the switch allows a maximum of 96 LAGs and each LAG supports a maximum of 8 member interfaces.
On other models:
  • When 64 is specified, the switch allows a maximum of 64 LAGs and each LAG supports a maximum of 32 member interfaces.
  • When 128 is specified, the switch allows a maximum of 128 LAGs and each LAG supports a maximum of 16 member interfaces.
V100R005C10 and later versions:
  • When 64 is specified, the switch allows a maximum of 64 LAGs and each LAG supports a maximum of 32 member interfaces.
  • When 128 is specified, the switch allows a maximum of 128 LAGs and each LAG supports a maximum of 16 member interfaces.
  • When 256 is specified, the switch allows a maximum of 256 LAGs and each LAG supports a maximum of 8 member interfaces.
  • When 512 is specified, the switch allows a maximum of 512 LAGs and each LAG supports a maximum of 4 member interfaces.
  • When 1024 is specified, the switch allows a maximum of 1024 LAGs and each LAG supports a maximum of 2 member interfaces.
