| Description | An AAA server configuration identified by its protocol
and its index.
An entry is created/removed when a server is defined
or undefined with IOS configuration commands via
CLI or by issuing appropriate sets to this table
using snmp.
A management station wishing to create an entry should
first generate a random number to be used as the index
to this sparse table. The station should then create the
associated instance of the row status and row index objects.
It must also, either in the same or in successive PDUs,
create an instance of casAddress where casAddress is the
IP address of the server to be added.
It should also modify the default values for casAuthenPort,
casAcctPort if the defaults are not appropriate.
If casKey is a zero-length string or is not explicitly set,
then the global key will be used. Otherwise, this value
is used as the key for this server instance.
Once the appropriate instance of all the configuration
objects have been created, either by an explicit SNMP set
request or by default, the row status should be set to
active(1) to initiate the request.
After the AAA server is made active, the entry can not be
modified - the only allowed operation after this is to
destroy the entry by setting casConfigRowStatus to destroy(6).
casPriority is automatically assigned once the entry is
made active and reflects the relative priority of the
defined server with respect to already configured servers.
Newly-created servers will be assigned the lowest priority.
To reassign server priorities to existing server entries,
it may be necessary to destroy and recreate entries in order
of priority.
Entries in this table with casConfigRowStatus equal to
active(1) remain in the table until destroyed.
Entries in this table with casConfigRowStatus equal to
values other than active(1) will be destroyed after timeout
(5 minutes).
If a server address being created via SNMP exists already
in another active casConfigEntry, then a newly created row
can not be made active until the original row with the
with the same server address value is destroyed.
Upon reload, casIndex values may be changed, but the
priorities that were saved before reload will be retained,
with lowest priority number corresponding to the higher
priority servers. |
