Chapter 1 CLI Command Reference
asr901-ecmp-hash-config ipv4-type
asr901-ecmp-hash-config ipv4-type
To specify equal-cost multi-path routing (ECMP) hashing algorithm for IPv4 configuration, use the
asr901-ecmp-hash-config ipv4-type command in global configuration mode. To remove this
configuration, use the no form of this command.
asr901-ecmp-hash-config ipv4-type {dest-addrs | dest-l4-port | l3-proto-id | outer-vlan |
src-addrs | src-intf | src-l4-port} add
no asr901-ecmp-hash-config ipv4-type {dest-addrs | dest-l4-port | l3-proto-id | outer-vlan |
src-addrs | src-intf | src-l4-port} add
Syntax Description
Command Default The ECMP parameters, such as dest-l4-port, src-intf, and src-l4-port, are disabled by default.
Command Modes Global configuration (config)#
Command History
Usage Guidelines This command is used to configure IPv4 type ECMP hash configurations for improved load distribution
of IP traffic. All the ECMP parameters are enabled by default except dest-l4-port, src-intf, and
src-l4-port. You should configure the asr901-ecmp-hash-config ipv4-type command to enable them.
Examples The following example shows how to configure IPv4 type ECMP hash configuration on a
CiscoASR901router:
Router# configure terminal
Router(config)# asr901-ecmp-hash-config ipv4-type dest-addrs
Router(config)# asr901-ecmp-hash-config ipv4-type dest-addrs add
dest-addrs Specifies the destination IPv4 address.
dest-l4-port Specifies the destination Layer 4 port.
l3-proto-id Specifies the Layer 3 protocol identifier.
outer-vlan Specifies the outer virtual local area network (VLAN).
src-addrs Specifies the source IPv4 address.
src-intf Specifies the source or the incoming interface.
src-l4-port Specifies the source Layer 4 port.
add Adds IPv4 ECMP hash configuration.
