Configure Cef; Enable Cef; Enable Per-Packet Load Balancing; Enable Network Accounting For Cef - Cisco 2610XM Configuration

3 Configure CEF

Load balancing is based on a combination of source and destination packet information;
it allows you to optimize resources by distributing traffic over multiple equal-cost
connections for transferring data to a destination. You configure load balancing on
outbound interfaces on a per-destination or per-packet basis.

3.1 Enable CEF

To enable CEF, use the following command in global configuration mode:
Router(config)# ip cef

3.2 Enable Per-Packet Load Balancing

Per-destination load balancing is enabled by default when you enable CEF. Typically,
you would disable per-destination load balancing when you want to enable per-packet
load balancing. To disable per-destination load balancing, use the following command
in interface configuration mode:
Router (config-if) # no ip load-sharing per-destination
To enable per-packet load balancing, use the following command in interface
configuration mode:
Router (config-if) # ip load-sharing per-packet

3.3 Enable Network Accounting for CEF

Hash bucket accounting to collect statistics is better to understand Cisco Express
Forwarding patterns in your network. Use the following command to enable it:
Router (config) # ip cef accounting load-balance-hash

3.4 Verifying CEF

Use the use the following commands in privileged EXEC mode to view the path-to-
bucket assignment result from the hash bucket accounting
Router# show ip cef {prefix} internal
