Load Sharing Commands
38.1 Load Sharing Overview
The Switch learns the next-hop(s) using ARP and determines routing path(s) for a destination.
The Switch supports Equal-Cost MultiPath (ECMP) to forward packets destined to the same
device through different routing paths of equal path cost. This allows you to balance or share
traffic loads between multiple routing paths when the Switch is connected to more than one
next-hop. ECMP works with static routes or a routing protocol, such as OSPF.
With ECMP, packets are routed through the paths of equal cost according to the hash
algorithm output.
The maximum number of paths for one ECMP (Equal-Cost MultiPath) route varies by Switch.
A smaller number of maximum-paths means more ECMP routes are allowed and a larger
number of maximum-paths means fewer ECMP routes are allowed.
The number of paths for a static route for ECMP cannot be bigger than the maximum-paths
value.
Throughput may be influenced while configuring ECMP maximum-paths.
38.2 Command Summary
The following section lists the commands for this feature.
Table 114 load-sharing Command Summary
COMMAND DESCRIPTION M P
ip load-sharing Enables load sharing on the Switch. C 13
ip load-sharing <sip|sip-dip> Sets the criteria the Switch uses to determine the routing path
for a packe.
sip: the Switch uses a hash algorithm to convert a packet’s
source IP address into a hash value which acts as an index to
a route path.
sip-dip: the Switch uses a hash algorithm to convert a
packet’s source and destination IP addresses into a hash
value which acts as an index to a route path.
C13
ip load-sharing aging-time <0-
86400>
Sets the time interval (from 0 to 86400 in increments of 10) in
seconds at which the Switch sends an ARP request to update
a resolved next-hop’s MAC address.
C13
ip load-sharing discover-time
<0-86400>
Sets the time interval (from 0 to 86400 in increments of 10) in
seconds at which the Switch sends an ARP request to update
an unresolved next-hop’s MAC address.
