ExtremeWare XOS 11.5 supports only the Summit X450 family of switches and the BlackDiamond 8800 series switch.

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
If you attempt to insert a 10G4X module into a BlackDiamond 8800 chassis configured for more than
32 LAGs, the 10G4X module fails the Init state with log error messages at the warning level similar
to the following:
04/07/1921 23:52:28.29 <Warn:DM.Warning> MSM-A: Slot-8 FAILED (1) Error Max Load Share
Groups Exceeded(-48) from HAL on CardExec INIT(5) for slot
04/07/1921 23:52:28.29 <Warn:DM.Warning> MSM-A: Error Max Load Share Groups Exceeded(-
48) from HAL on CardExec INIT(5) for slot 8
Once you configure more than 32 LAGs on a BlackDiamond 8800 chassis, the 10G4X module will not
initialize even if you reduce the number of LAGs to 32; you must reboot the system first. The system
logs an error message at the error level similar to the following when you must reduce the system
(even if you reduced the number of LAGs to 32):
04/07/1921 23:52:28.29 <Erro:HAL.Card.Error> MSM-A: Slot 8 is not supported when more
than 32 load share groups have previously been configured. A system reboot is
required to clear this condition.
BlackDiamond 10808 and 12804 switch only.
The following guidelines apply to load sharing on the
BlackDiamond 10808 and 12804 switch:
●
A static LAG can include a maximum 16 ports.
●
An LACP (dynamic) LAG can include a maximum of 32 ports; out of these up to 16 can be selected
links and the remaining 16 will be standby links.
●
The maximum number of LAGs is 128.
On the BlackDiamond 10808 and 12804 switch, if you do not explicitly select an algorithm, the port-
based scheme is used. However, the address-based algorithm has a more even distribution and is the
recommended choice.
NOTE
You must use the
configure sharing address-based
command to configure address-based load sharing on
the BlackDiamond 10808 and 12804 switch.
Example
The following example defines a static link aggregation group (LAG) on a modular switch that contains
ports 9 through 12 on slot 3, ports 7 through 10 on slot 5, and uses the first port on slot 3 as the logical
port 9 on a modular switch:
enable sharing 3:9 grouping 3:9-3:12, 5:7-5:10
In this example, logical port 3:9 represents physical ports 3:9 through 3:12 and 5:7 through 5:10.
