IP Accounting
IP accounting provides basic IP accounting functions. By enabling IP accounting,
users can see the number of bytes and packets switched through the software on a
source and destination IP address basis. Only transit IP traffic is measured and only on
an outbound basis; traffic generated by the software or terminating in the software is
not included in the accounting statistics. To maintain accurate accounting totals, the
software maintains two accounting databases: an active and a checkpoint database.
IP accounting also provides information identifying IP traffic that fails IP access lists.
Identifying IP source addresses that violate IP access lists alerts you to possible
attempts to breach security. The data also indicates that you should verify IP access
list configurations. By default, IP accounting displays the number of packets that have
passed access lists and were routed.
1. To enable IP accounting, use the following command for each interface in
Interface Configuration mode:
MOT(config-if)#ip accounting
2. To configure other IP accounting functions, use one or more of the following
commands in Global Configuration mode. Set the maximum number of
accounting entries to be created.
MOT(config)#ip accounting-threshold <num>
where:
num is the maximum number of accounting entries; valid entries are from 0
to 10000.
3. To filter accounting information for hosts, use the ip accounting-list command
in Global Configuration mode, as shown below:
MOT(config)#ip accounting-list <prefix> <mask>
where:
prefix is the host IP address.
mask is the wildcard mask.
