Adding and Deleting Ports in a Load-Sharing Group
Ports can be added or deleted dynamically in a load-sharing group, or LAG. To add or delete ports
from a load-sharing group, use the following commands:
configure sharing <port> add ports <port_list>
configure sharing <port> delete ports <port_list>
Configuring Load Sharing on the BlackDiamond 8800 Family of Switches and the
Summit X450 Switch
The following rules apply to load sharing on the BlackDiamond 8800 family of switches and the
Summit X450 switch:
●
One static LAG can contain up to 8 ports.
●
The maximum number of LAGs is 32.
●
Any broadcast, multicast, or unknown unicast packet is transmitted on a single port of a LAG.
●
You can configure only the address-based load-sharing algorithm.
●
The default load-sharing algorithm is L2 address-based aggregation.
NOTE
See “Configuring LACP” on page 124 for the maximum number of links, selected and standby, per LACP.
Configuring Load Sharing on the BlackDiamond 10K Series of Switches
The following rules apply to load sharing on the BlackDiamond 10K series of switches:
●
One static LAG can contain up to 16 ports.
●
The maximum number of LAGs is 128.
●
You cannot specify L2 or L3 address-based load sharing.
●
The default load-sharing algorithm is port-based aggregation.
NOTE
See “Configuring LACP” on page 124 for the maximum number of links, selected and standby, per LACP.
Load Sharing Rules and Restrictions for All Switches
Additionally, the following rules apply to load sharing on all switches:
●
The ports in the LAG do not need to be contiguous.
●
A LAG that spans multiple modules must use ports that have the same maximum bandwidth
capability, with one exception—you can mix media type on 1 Gbps ports.
Configuring LACP
To configure LACP, or dynamic link aggregation, you must, again, first create a LAG. The first port in
the LAG serves as the logical port for the LAG. This is the reference port used in configuration
