completed any required start up routines and
therefore the ctAliasTable and ctAliasControlTable
are not currently valid.
ready(2) indicates that the agent has completed
all initialization procedures and that the alias
MIB is running properly.
full(3) indicates that due to memory restrictions
on the agent, the ctaliasTable has reached the
maximum number of entries possible.
NOTE: If an agent is using a circular queue design,
then the state of full(3) will never be set.

discovered.
The ifIndex is an 'external value' that identifies a
physical component associated with the Alias entry.
This object can be used to identify the physical
location of the interface in the ifTable [RFC2863].
The possibility of ifIndex value re-assignment must be
accommodated by a management application whenever the
value of sysUpTime is reset to zero.
Since ifIndex values in different 'naming scopes' are
not related to one another, the interface to physical
component associations are relative to the same
logical entity within the agent. For more discussion
of naming scopes, see the ENTITY-MIB [RFC2037]
|
| ctAliasMacAddress |
.1.3.6.1.4.1.52.4.1.3.7.1.1.1.1.4 |

format of this object will depend upon the protocol
type in ctAliasProtocol. The value returned for
this object MUST be in a non-textual format.
|
| ctAliasIsActive |
.1.3.6.1.4.1.52.4.1.3.7.1.1.1.1.8 |
|
The status of this entry.
A true(1) value indicates the alias is active.
A false(2) value indicates an entry which has
been marked inactive by network management, using the
ctAliasEntryStatus object in the ctAliasControlTable.
Entries which have been marked inactive may remain in
the table to allow consistent mappings between network
management stations until an agent needs to free
resources.
|
| ctAliasAddressText |
.1.3.6.1.4.1.52.4.1.3.7.1.1.1.1.9 |
|
The address associated with this entry in a human
readable textual format.

is re-initialized, i.e. sysUpTime is reset to zero.
|
| ctAliasMarkInactive |
.1.3.6.1.4.1.52.4.1.3.7.1.1.2.1.2 |
|
This object provides the control to mark this entry
to inactive.
When an entry is created by the agent, this is set to
false(2). A network management application can set this
value to true(1), indicating that the entry is no longer
needed. Once this object has been set to true(1), it
cannot be set to false(2).
If the alias is detected again by the agent, the agent
may create a new entry for the Alias.
When an agent needs to free up resources, it may choose
to delete those entries marked inactive.
|
| ctAliasEntryStatus |
.1.3.6.1.4.1.52.4.1.3.7.1.1.2.1.3 |
|
This object provides the control to remove or inactivate
entries that are no longer needed.
active(1) - indicates that this entry is active.
inactive(2) - indicates that this entry is no longer of any
interest and can be removed, as needed, by
the entity. If the alias is marked inactive
and is seen again by the agent, the alias
ID's status will be changed to active.
remove(3) - indicates that the agent SHOULD immediately
remove the entry from the table. If the alias
is seen again by the agent after having been
removed, it will be added as a new aliasID.
|
| ctAliasConfigurationInterfaceTotalEntries |
.1.3.6.1.4.1.52.4.1.3.7.1.1.4.3.1.1 |
|
The total number of alias entries currently in
use by this ctAliasInterface.
|
| ctAliasConfigurationInterfaceMaxEntries |
.1.3.6.1.4.1.52.4.1.3.7.1.1.4.3.1.2 |
|
This object represents the maximum number of
alias entries in the ctAliasTable which were
created by this ctAliasInterface. When the object
ctAliasConfigurationInterfaceTotalEntries
equals this object, the next alias appearing
on this ctAliasInterface causes the oldest entry
created by this ctAliasInterface to be deleted.
The sum of this object across all ctAliasInterface
shall not exceed ctAliasConfigurationSystemTotalEntries.
If the value of this object is increased, then oldest
entry removal ceases until the maximum is reached
again. If management reduces the value of this
object, then, starting with the oldest, alias
entries are removed until the new number of
entries is reached.
|
| ctAliasConfigurationInterfaceEnableState |
.1.3.6.1.4.1.52.4.1.3.7.1.1.4.3.1.3 |
|
The enable state of the alias agent on this
ctAliasInterface.
|
| ctAliasConfigurationNumQueueWraps |
.1.3.6.1.4.1.52.4.1.3.7.1.1.4.3.1.4 |
|
This object represents the number of times the queue for
this ctAliasConfigurationEntry has wrapped. Since circular
queues are used for storing the entries, when all allocated
entries are used, the oldest entries are reused, thus
creating a wrap condition. A value of zero indicates the
queue has not wrapped, except in the case that the counter
itself has wrapped.
|
| ctAliasMacAddressInterface |
.1.3.6.1.4.1.52.4.1.3.7.1.1.5.1.1 |
|
The ifIndex of the interface on which this entry was
discovered.
The ifIndex is an 'external value' that identifies a
physical component associated with the Alias entry.
This object can be used to identify the physical
location of the interface in the ifTable [RFC2863].
The possibility of ifIndex value re-assignment must be
accommodated by a management application whenever the
value of sysUpTime is reset to zero.
Since ifIndex values in different 'naming scopes' are
not related to one another, the interface to physical
component associations are relative to the same
logical entity within the agent. For more discussion
of naming scopes, see the ENTITY-MIB [RFC2037]

|
The status of this entry.
A true(1) value indicates the alias is active.
A false(2) value indicates an entry which has
been marked inactive by network management, using the
ctAliasEntryStatus object in the ctAliasControlTable.
Entries which have been marked inactive may remain in
the table to allow consistent mappings between network
management stations until an agent needs to free
resources.

The value of sysUpTime when this entry was last modified.
|
| ctAliasTable |
.1.3.6.1.4.1.52.4.1.3.7.1.1.1 |
|
The ctAliasTable contains information about the aliases
known by the agent. This table is indexed using a unique
and arbitrary ID and a TimeFilter to allow a management
station to learn all alias entries that have been modified
since time X. This table is NOT designed to do a single
GET. This Table is designed for MIB Walks only.
This table contains objects that map upper-layer
network services and entities to the physical location
of the associated port, and the MAC address of the
associated end-system (node).
All entries in this table are deleted when sysUpTime
is reset to zero.
This table allows for a time filtered view. It is useful
for determining what has been modified in the Alias Table
since a specified time.
If a management station reads the ctAliasTable
of an entity at time X, subsequent updates can be
realized by performing get-next requests of this
table to determine which entries have been modified
since time X. Then the management station can use
GET requests to retrieve only the records of interest
from the Alias table.
There is a delay between retrieving the Alias Reference
values from this table, and a GET request to retrieve a
modified row from the Alias table. The management
station should be prepared for two possibilities:
1) the GET request may fail if the Alias table entry
has been deleted during the delay, and 2) the
entry may have been modified during the delay, so the
modification time of the retrieved entry may differ from
the modification time of the Delta entry.
If the entry in the Alias Control table identified by
ctAliasID is marked inactive by management request, and
subsequently deleted to free resources, all corresponding
entries in this table are also deleted.
If the agent needs to free resources, it can delete
entries from this table. It SHOULD first remove those
which have been marked inactive in the ctAliasControlTable,
then it SHOULD remove those entries with the oldest
modification times.
|
| ctAliasControlTable |
.1.3.6.1.4.1.52.4.1.3.7.1.1.2 |
|
This table allows for control of Alias entries.
Currently control is limited to marking entries
as marked for deletion.
If the entry in the Alias Control table identified by
ctAliasID is marked inactive by management request, and
subsequently deleted to free resources, all corresponding
entries in the ctAlias table are also deleted.
All entries in this table are deleted when sysUpTime
is reset to zero.
|
| ctAliasConfigurationTable |
.1.3.6.1.4.1.52.4.1.3.7.1.1.4.3 |
|
This table is used to prevent any single chatty
port from monopolizing all of the available alias
buffers in the system by letting an administrator
tune each port.
|
| ctAliasMacAddressTable |
.1.3.6.1.4.1.52.4.1.3.7.1.1.5 |
|
The ctAliasMacAddressTable contains information about
the aliases known by the agent indexed by MAC address
and protocol.
This table contains information that is identical to
the ctAliasTable, but it is instanced by MAC address
and protocol to allow management entities to search for
a MAC address and protocol, or part of a MAC address
and protocol, using a single SNMP GetNext request.
|
| ctAliasProtocolAddressTable |
.1.3.6.1.4.1.52.4.1.3.7.1.1.6 |
|
The ctAliasProtocolAddressTable contains information
about the aliases known by the agent indexed by protocol
and address.
This table contains information that is identical to the
ctAliasTable, but it is instanced by protocol and address
to allow management entities to search for a protocol and
address, or part of a protocol and address, using a
single SNMP GetNext request.
