Maximum ECMP groups and paths The maximum number of ECMP groups supported on the switch depends on the maximum ECMP paths configured on the switch. To view the maximum number of ECMP groups and paths, use the show ip ecmp-group details command. OS10# show ip ecmp-group details Maximum Number of ECMP Groups : 256 Maximum ECMP Path per Group : 64 Next boot configured Maximum ECMP Path per Group : 64 The default value for the maximum number of ECMP paths per group is 64. This value is configurable and you can configure a maximum of up to 128 ECMP paths per group. The Maximum ECMP Path per Group is the current value configured in the hardware. The Next boot configured Maximum ECMP Path per Group is the value that is configured for maximum ECMP path and will take effect after the next reboot. You can increase or decrease the maximum number of ECMP groups using the ip ecmp-group maximum-paths number command. The number of ECMP groups is inversely proportional to the number of ECMP paths. To configure maximum paths per ECMP route: OS10# configure terminal OS10(config)# ip ecmp-group maximum-paths 10 OS10(config)# exit OS10# write memory OS10# reload ECMP commands enhanced-hashing Ensures that existing traffic flows are not remapped when a member link goes down. Syntax Parameters enhanced-hashing resilient-hashing {lag | ecmp} ● resilient-hashing-Enter the keyword to enable enhanced-hashing. ● {ecmp | lag}-Enter the keyword to enable resilient hashing for a port channel or ECMP group. Defaults Command Mode Usage Information Example Disabled CONFIGURATION The no version of this command disables resilient hashing. For supported platforms, see Supported platforms. OS10(config)# enhanced-hashing resilient-hashing ecmp Supported Releases OS10(config)# enhanced-hashing resilient-hashing lag 10.4.3.0 or later hash-algorithm Changes the hash algorithm that distributes traffic flows across ECMP paths and the link aggregation group (LAG). Syntax hash-algorithm {ecmp | lag | seed {seed-value}} {crc | crc16cc | crc32LSB | crc32MSB | xor | xor1 | xor2 | xor4 | xor8 | random} Layer 3 705
