Version Description
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]}
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 traffic 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 fields to hash.
source-ip Uses source IP address and source port fields to hash.
mac {dest-mac |
source-dest-mac
| source-mac}
Enter the keywords to distribute MAC traffic based on the following criteria:
dest-mac Uses the destination MAC address, VLAN, Ethertype, source module
ID and source port ID fields to hash.
source-dest-mac Uses the destination and source MAC address, VLAN,
Ethertype, source module ID and source port ID fields to hash.
source-mac Uses the source MAC address, VLAN, Ethertype, source module
ID and source port ID fields to hash.
tcp-udp enable Enter the keywords to distribute traffic based on the following:
enable Takes the TCP/UDP source and destination ports into consideration
when doing hash computations. This option is enabled by default.
ingress-port enableEnter the keywords to distribute traffic based on the
following:enable Takes the source port into consideration when doing hash
computations. This option is disabled by default.
Defaults IP 4-tuple (IP SA, IP DA, Source Port, Destination Port)
