keepalive
Send keepalive packets periodically to keep an interface alive when it is not transmitting data.
Syntax
keepalive [seconds]
To stop sending keepalive packets, use the no keepalive command.
Parameters
seconds (OPTIONAL) For interfaces with PPP encapsulation enabled, enter the number of
seconds between keepalive packets. The range is from 0 to 23767. The default is 10
seconds.
Defaults Enabled.

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 congure keepalive, the system sends a self-addressed packet out of the congured interface to
verify that the far end of a WAN link is up. When you congure 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 trac over members of
a Port Channel as well as equal-cost paths. To designate another method to balance trac 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]}
To return to the default setting (IP 4-tuple), use the no load-balance {ip-selection [dest-ip |
source-ip]} | {mac [dest-mac | source-dest-mac | source-mac]} | {tcp-udp |
ingress-port [enable]} command.
Parameters
ip-selection {dest-ip
| source-ip}
Enter the keywords to distribute IP trac based on the following criteria:
NOTE: The hashing mechanism returns a 3-bit index indicating which port the
packet should be forwarded.
dest-ip — Uses destination IP address and destination port elds to hash.
source-ip — Uses source IP address and source port elds to hash.
