Description
Note:
The configure>system>resource-profile context is supported on the 7210 SAS-T, 7210 SAS-
Mxp, 7210 SAS-Sx/S 1/10GE: standalone, and 7210 SAS-Sx 10/100GE.
The configure>system>global-res-profile context is supported on the 7210 SAS-R6,
7210 SAS-R12, and 7210 SAS-Sx/S 1/10GE: standalone-VC.
This command configures the maximum amount of routes of same cost to the same IP destination/prefix
when path sharing is enabled using IP ECMP. To enable optimum usage of hardware resources, software
allocates hardware resources in groups of fixed number of entries. A group is a set of IP next-hop entries
used by ECMP routes. The number of IP next-hop entries per group (which in turn dictates the maximum
number of shared IP paths per IP destination/prefix) is also specified with commands. The software uses
the same group if all the IP next-hop in use for the ECMP routes is the same.
This parameter also dictates the maximum number of paths that a single LDP FEC can use.
This command does not enable the use of IP ECMP. To enable IP ECMP, the user must use the config
router ecmp command. The number of routes specified using the config router ecmp command cannot
exceed the number of routes specified by this command, though it can be lesser. If its lesser, the software
will use only the specified number routes. Specifying a lesser number of routes with config router ecmp
will result in wastage of hardware resources. To enable LDP ECMP, see the configure system resource-
profile router ldp-ecmp command.
Note:
• This command is a boot-time parameter and any change will take effect only after a reboot.
• On 7210 SAS-R6 and 7210 SAS-R12, the value specified with this command is used across
all IMMs in the chassis.
