aggr mode This command selects the load-balance method to apply to all link
aggregation groups on the switch. If more than one option is selected,
each factor is used in the hash algorithm to determine the port member
within the trunk to which a frame will be assigned.
SYNTAX
aggr mode [smac | dmac | ip | port] [enable | disable]
smac (Source MAC Address) - All traffic with the same source MAC
address is output on the same link in a trunk. This mode works best
for switch-to-switch trunk links where traffic through the switch is
received from many different hosts.
dmac (Destination MAC Address) - All traffic with the same
destination MAC address is output on the same link in a trunk. This
mode works best for switch-to-switch trunk links where traffic
through the switch is destined for many different hosts. Do not use
this mode for switch-to-router trunk links where the destination
MAC address is the same for all traffic.
ip (IP Address) - All traffic with the same source and destination IP
address is output on the same link in a trunk. This mode works best
for switch-to-router trunk links where traffic through the switch is
destined for many different hosts. Do not use this mode for switch-
to-server trunk links where the destination IP address is the same
for all traffic.
port (TCP/UDP Port Number) - All traffic with the same source and
destination TCP/UDP port number is output on the same link in a
trunk. Avoid using his mode as a lone option. It may overload a
single port member of the trunk for application traffic of a specific
type, such as web browsing. However, it can be used effectively in
combination with the IP Address option.
