AOS Release 6.4.6.R01 Release Notes November 2013
Monitoring/Troubleshooting Features
Gigaword Packet Counters
Acct-Input-Octets (type-42) and Acct-Output-Octets (type-43) are sent to the RADIUS Server in
accounting packets. These statistics are used by the service providers for billing of users. As these two
fields are 4 bytes longer as per the RADIUS standard, it can support a maximum value of 4GB (2^32 -1=
4,294.967,295). Whenever a user uses more than 4GB, the exact count of usage is lost.
Acct-Input-Gigawords (type-52) and Acct-Output-Gigawords (type-53) attributes are introduced to
overcome the limitation due to the 4 bytes size of Acct-Input-Octets and Acct-Output-Octets. These
attributes indicates how many times the Acct-Input-Octets and Acct-Output-Octets counter has wrapped the
4GB traffic over the course the service being provided.
Whenever the input octets and output octets exceeds 2^32-1 bytes, before sending accounting packet to the
RADIUS Server, these octets are converted into multiples of 4GB and will be sent in Acct-Input-
Gigawords (type-52) and Acct-Output-Gigawords (type -53) attributes. For every 4GB traffic, the value is
incremented and the remaining amount of traffic is displayed in Acct-Input-Octets and Acct-Output-Octets
attribute.
