Version Description
9.9(0.0) Introduced on the FN IOM.
9.4(0.0) Supported on the FN I/O Aggregator.
9.2(0.0) Supported on the M I/O Aggregator.
8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information When you configure keepalive, the system sends a self-addressed packet out of
the configured interface to verify that the far end of a WAN link is up. When you
configure no keepalive, the system does not send keepalive packets and so the
local end of a WAN link remains up even if the remote end is down.
load-balance
By default, Dell Networking OS uses an IP 4-tuple (IP SA, IP DA, Source Port, and Destination Port) to
distribute IP traffic over members of a Port Channel as well as equal-cost paths. To designate another
method to balance traffic over Port Channel members, use the load-balance command.
Syntax
load-balance {ip-selection [dest-ip | source-ip]} | {mac [dest-
mac | source-dest-mac | source-mac]} | {tcp-udp | ingress-port
[enable]}
