destination-mac: Performs load sharing in link aggregation groups based on destination MAC address.
destination-port: Performs load sharing in link aggregation groups based on destination port.
ingress-port: Performs load sharing in link aggregation groups based on ingress port.
source-ip: Performs load sharing in link aggregation groups based on source IP address. Support for this
keyword depends on your device model and current view.
source-mac: Performs load sharing in link aggregation groups based on source MAC address.
source-port: Performs load sharing in link aggregation groups based on source port.
Description
Use the link-aggregation load-sharing mode command to configure the global or group-specific
link-aggregation load sharing criteria.
Use the undo link-aggregation load-sharing mode command to restore the default.
By default, the global aggregation load sharing criteria are ingress port, source MAC address and
destination MAC address for Layer 2 packet types, such as ARP, and source and destination IP addresses
for Layer 3 packet types, such as IP packet. The global link-aggregation load sharing criteria are the
default for all link aggregation groups.
You can set the following global link-aggregation load sharing criteria:
• Source IP address
• Destination IP address
• Source MAC address
• Destination MAC address
• Source IP address and destination IP address
• Source IP address and source port number
• Destination IP address and destination port number
• Any two or all three of these elements – ingress port number, source MAC address, and destination
MAC address
You can set the following group-specific load sharing criteria:
• Source IP address
• Destination IP address
• Source IP address and destination IP address
• Source MAC address
• Destination MAC address
• Destination MAC address and source MAC address
If unsupported aggregation load sharing criteria are configured, an error prompt will appear.
NOTE:
• The load sharing criteria that you configure will overwrite the previous criteria.
• A link aggregation group preferentially uses group-specific load sharing criteria. If no group-specific
load sharing criteria is available, the group uses global load sharing criteria.
• By default, an aggregation group uses the global link-aggregation load sharing criterion or criteria. You
can configure the group-specific link-aggregation load sharing criteria to overwrite the global ones,
except those specified with the destination-port, source-port, or ingress-port keywords.
