Commands for Configuring Slots and Ports on a Switch
ExtremeWare XOS 11.5 supports only the Summit X450 family of switches and the BlackDiamond 8800 series switch.

●
The default load-sharing algorithm is L2 address-based aggregation. Any broadcast, multicast, or
unknown unicast packet is transmitted on a single port in the LAG.
●
The available address-based parameters on the Summit X450 family of switches are as follows:
■
Summit X450 switch—L2 for Layer 2 and L3 for Layer 3. If the packet is not IP, the switch applies
the Layer 2 algorithm, which is the default setting.
■
Summit X450a and X450e series switches—L2 for Layer 2, L3 for Layer 3, and L3_L4 for Layer 3/
Layer 4.
NOTE
You cannot configure port-based load sharing algorithm on the Summit X450 family of switches; you configure only
address-based load-sharing algorithms.
BlackDiamond 8800 series switch only.
The following guidelines apply to link aggregation on the
BlackDiamond 8800 series switch:
●
A static LAG can include a maximum of 8 ports.
●
An LACP (dynamic) LAG can include a maximum of 16 ports; out of these up to 8 can be selected
links and the remaining 8 will be standby links.
●
Any broadcast, multicast, or unknown unicast packet is transmitted on a single port in the LAG.
NOTE
You cannot configure port-based load sharing algorithm on the BlackDiamond 8800 series switch and the Summit
X450 family of switches; you configure only address-based load-sharing algorithms.
●
The available address-based parameters on the BlackDiamond 8800 series switch are L2 for Layer 2
and L3 for Layer 3. If the packet is not IP, the switch applies the Layer 2 algorithm, which is the
default setting.
●
Beginning with ExtremeWare XOS version 11.5, the maximum number of LAGs is 128 unless a
10G4X module is in use in the chassis, in which case the maximum number of LAGs is 32.
NOTE
You cannot configure more than 32 LAGs on a BlackDiamond 8800 chassis with a 10G4X module running or that
has a slot configured for the 10G4X module.
If you attempt to configure more than 32 LAGs on a BlackDiamond 8800 chassis that contains an
10G4X module or has a slot configured for the 10G4X module, the system displays the following
error message:
Error: Slot <slot_number> can support a maximum of 32 trunks
If you want to configure more than 32 LAGs on this chassis, it is not necessary to remove the 10G4X
module; however, you must
both
unconfigure the slot holding the 10G4X module
and
disable the slot
holding that module or remove the 10G4X module. Use the following commands to unconfigure the
slot and disable that slot:
unconfigure slot
and
disable slot
