An example configuration with allowed peering:
OS6860-> show configuration snapshot linkagg
! Link Aggregate:
linkagg lacp agg 1 size 2 admin-state enable
linkagg lacp agg 1 actor admin-key 1
linkagg lacp port 1/1/1 actor admin-key 1
linkagg lacp port 1/1/2 actor admin-key 1
LACP BPDU processing on software level
Once the packets were classified as "trap to CPU" on the ASIC level the packets were placed in CPU port
queue. There are 32 internal queues out of which 27 are used for LACP. The pktDriver receives the packet via
DMA transfer from the Broadcom ASIC, classifies the packet as LACP, and sends the packet to the LACP
module for further software processing.
Hash-control
Hash may be controlled for each linkagg separately using the following command:
OS6860-> linkagg lacp agg 1 hash ?
^
TUNNEL-PROTOCOL SOURCE-AND-DESTINATION-MAC
SOURCE-AND-DESTINATION-IP SOURCE-MAC SOURCE-IP
DESTINATION-MAC DESTINATION-IP
(Link Aggregation Command Set)
Support of 256 aggregates and up to 16 ports
