ctSmartTrunk 1.3.6.1.4.1.52.4.1.2.20.1
This mib module defines a portion of the SNMP enterprise MIBs under Cabletron enterprise OID pertaining to configuration of Smart TRUNK network links.

OBJECT IDENTIFIER    

ctTrunkGlobalStatus 1.3.6.1.4.1.52.4.1.2.20.1.1.1
The state of Smart TRUNK capability for this entire managed entity. Default Value is True(1). If set to False(2) all smart trunks are put into ifAdminStatus down.
OBJECT-TYPE    
  TruthValue  

ctTrunkConfigTable 1.3.6.1.4.1.52.4.1.2.20.1.1.3
A table describing all of the trunk interfaces implemented by this host. Each trunk has a row in the MIB-II/RFC 2233 Interfaces table (describing the structure of the trunk interface it presents to higher layers). Each trunk interface also has a row in this and other CTRON-SMARTTRUNK-MIB tables. Smart Trunks use ifType propMultiplexor(54). Counters represent the aggregate of all physcal links. Unlike hardware ports, trunk interfaces can be created by management. However, the RFC 2233 Interfaces table does not directly support row creation. Therefore, creating or deleting a row in the ctTrunkConfigTable is defined to have the side effect of creating or deleting corresponding rows in - the MIB-II / RFC 2233 Interfaces table, - any other dependent tables New Interfaces table rows for trunk intefaces always have 'ifAdminStatus' set to 'down' until the row state is becomes Active. Then administration of the interface uses normal ifTable ifAdminStatus to enabled it.

  SEQUENCE OF  
    CtTrunkConfigEntry

ctTrunkConfigEntry 1.3.6.1.4.1.52.4.1.2.20.1.1.3.1
Each table entry contains configuration information for one trunk interface.
OBJECT-TYPE    
  CtTrunkConfigEntry  

ctTrunkIndex 1.3.6.1.4.1.52.4.1.2.20.1.1.3.1.1
A value which uniquely identifies this conceptual row in the ctTrunkConfigTable. The Table allows sparse values. If the conceptual row identified by this value of ctTrunkIndex is recreated following an agent restart, the same value of ctTrunkIndex must be used to identify the recreated row. (However, the Interfaces table index associated with the client may change. ifAlias in ifXTable is used then to reassociate ifIndexes based on ifAlias. In the case of the SSR, Smart Trunks are manipulated as st.ctTrunkIndex
OBJECT-TYPE    
  CTSmartTrunkIndex  

ctTrunkConfigName 1.3.6.1.4.1.52.4.1.2.20.1.1.3.1.2
The Trunk's Name, just for informational purposes. It may be changed regardless of the RowStatus value.
OBJECT-TYPE    
  CTSmartTrunkName  

ctTrunkConfigProtocol 1.3.6.1.4.1.52.4.1.2.20.1.1.3.1.3
Trunking protocol in use. Once the row is active, it can not be changed.
OBJECT-TYPE    
  CTSmartTrunkProtocol  

ctTrunkConfigLoadBalance 1.3.6.1.4.1.52.4.1.2.20.1.1.3.1.4
The type of load balance algorithm applied to this trunk. Once Row is active, the agent may override this value with an implmentation specific default.
OBJECT-TYPE    
  CTSmartTrunkLoadBalanceType  

ctTrunkIfIndex 1.3.6.1.4.1.52.4.1.2.20.1.1.3.1.5
The ifIndex in ifTable, ifXTable that is associated with the trunk that is represented by this row.
OBJECT-TYPE    
  InterfaceIndex  

ctTrunkRowStatus 1.3.6.1.4.1.52.4.1.2.20.1.1.3.1.6
This object lets network managers create and delete trunk interfaces, on systems that support this optional capability. It does not control the activation and deactivation of these interfaces; they are controlled by 'ifAdminStatus' in the ifTable. However, changing row state from active to notInService. will have the side effect of changing their 'ifAdminStatus' values to 'noPresent' or 'down', thus causing any active trunk connections to be terminated. When creating a trunk interface, it is up to the management station to determine a suitable 'ctTrunkIndex'. To facilitate interoperability, agents should not put any restrictions on the 'ctTrunkIndex' beyond the obvious ones that it be valid and unused. The Managed Objects that must be set in this table for a row to change from nonExistent/notReady to notInService/Active is simply an index. Ports can then be added to the Smart TRUNK via the ifStackTable. If you create a trunk interface via this object, it will initially have 'ifAdminStatus' = 'down' 'ifOperStatus' = 'down' when RowStatus is changed to active.
OBJECT-TYPE    
  RowStatus  

ctTrunkConnectionTable 1.3.6.1.4.1.52.4.1.2.20.1.1.4
This table describes how local interfaces that are participating in a trunk are connected to remote interfaces. With this table, a management entity can determine that (for example) local interfaces 3, 4, and 6 are connected to remote interfaces 10, 17, and 19. This table is useful to debug configuration errors with remote devices. If ifAdminStatus/ifOperState is up, and no corresponding row is found in this table, then a management station can assume a the remote end does not have the decHuntGroup protocol active. Note: this entire table is read-only. Rows are created and deleted from this table as a side effect of trunks being created and deleted. Note: a managment entity could determine (for example) that interface 3 was participating in trunk 3 by using the ifStackTable and ctTrunkIfIndex.

  SEQUENCE OF  
    CtTrunkConnectionEntry

ctTrunkConnectionEntry 1.3.6.1.4.1.52.4.1.2.20.1.1.4.1
Each table entry contains configuration information for one interface that is participating in a trunk.
OBJECT-TYPE    
  CtTrunkConnectionEntry  

ctTrunkPortRemoteIfIndex 1.3.6.1.4.1.52.4.1.2.20.1.1.4.1.1
The ifIndex of the interface at the other end of this part of the trunk link. If this value is 0, then for some reason there is no interface on the other side of this link. This might be a temporary condition or it might represent a real problem. Note: this table is indexed by ifIndex. So the index is the local ifIndex value and ctTrunkPortRemoteIfIndex is the remote ifIndex.

  InterfaceIndex  

ctTrunkLLAPRequirement 1.3.6.1.4.1.52.4.1.2.20.1.2.1
Indicates whether this managed entity requires the LLAP updates to perform the trunking function. Certain families of products require LLAP (decHuntGroup Protocol) order for the Smart TRUNK functionality to work. A value of 1 implies that LLAP is necessary for smart-trunking to work on this platform, a value of 2 indicates that it is not necessary.
