The num variable species the number of paths and can be from 2-8. The default is 4. On the ICX 7750 device, the value of the num
variable can be from 2 through 32.
The conguration of the maximum number of IP load sharing paths to a value more than 8 is determined by the maximum number of
ECMP paths dened at the system level using the system-max max-ecmp command. You cannot congure the maximum number of IP
load sharing paths higher than the value dened at the system level.
To dene the maximum number of ECMP paths at the system level, enter a command such as the following.
device(config)# system-max max-ecmp 20
device(config)# write memory
device(config)# exit
device# reload
Syntax: [no] system-max max-ecmp [ num ]
The num variable species the maximum number of ECMP paths and the value range can be from 8 through 32. This is supported only
on the ICX 7750 device.
Changing the maximum load sharing paths for IPv6
By default, IPv6 ECMP load sharing allows
trac to be balanced across up to four equal paths.
To change the number of ECMP load sharing paths for IPv6, enter a command such as the following.
device(config)#ipv6 load-sharing 6
Syntax: [no] ipv6 load-sharing [ num ]
The num variable species the number of paths and can be from 2 through 8, depending on the device you are conguring. On the
Brocade ICX 7750, the value of the num variable can be from 2 through 32.
The conguration of the maximum number of IP load sharing paths to a value more than 8 is determined by the maximum number of
ECMP paths dened at the system level using the system-max max-ecmp command. You cannot congure the maximum number of IP
load sharing paths higher than the value dened at the system level. Also, you cannot congure the maximum number of ECMP paths at
the system level to a value less than the congured IP load sharing value.
To dene the maximum number of ECMP paths at the system level, enter a command such as the following.
device(config)# system-max max-ecmp 20
device(config)# write memory
device(config)# exit
device# reload
Syntax: [no] system-max max-ecmp [ num ]
The num variable
species the maximum number of ECMP paths and the value range can be from 8 through 32. This command is
supported only on the Brocade ICX 7750.
You must save the conguration and reload the device for the maximum ECMP value change to take eect.
Displaying ECMP load-sharing information for IPv6
To display the status of ECMP load sharing for IPv6, enter the following command.
device#show ipv6
Global Settings
unicast-routing enabled, hop-limit 64
No IPv6 Domain Name Set
No IPv6 DNS Server Address set
Prefix-based IPv6 Load-sharing is Enabled, Number of load share paths: 4
