LACP upgrade - 13: cleaning up LAG module

Cleaned up #LAG and #LACP modules with #miscellaneous #changes. Corrected the #PDU #handler in LACP module. Reordered PDU buffer data-structure. Removed definitions of the old module data-structures in LAG module. Corrected #aggregator #member-port #list iterator routine. Corrected #member-port #statistics iterator routines with direct references from member-port configuration entries. Updated #custom #aggregator configuration entries with direct reference from the aggregator configuration entries.

LACP upgrade - 12: updating member port selection handler

Updated #member-port #selection #handler in #LACP module. This handler checks and #verifies whether the #peer #partner and the #peer #port #attributes are not changing. The peer port info is recorded while LACP PDU is received. While there is an #administrative #configuration change from the peer side or a #physical #connectivity #changes happens from the remote side, it has to be decided whether the #member-port can still be part of #aggregation or not. The handler reads out the attributes passed in the LACP PDU and compare them against the peer port info recorded earlier. When the attributes differ in the PDU the member-port is marked as not part of the aggregation and #member-port #selection #procedures are executed.

LACP upgrade - 5: updating aggregator port state update handler

Updated #aggregator #port #status #handler in #LACP module. The data structure has been updated to use the new updated structure. This routine #updates the aggregator status as part of the #administrative or #operational #changes. The #LAG module uses this to #convey the aggregator #status #change to LACP module. When the aggregator port status changes to DOWN current aggregator selection is marked to be cleared. The remote information is marked as expired. This will cause the remote peer information to be gathered fresh again on port UP change. When port state comes as UP, the peer synchronization is marked as lost and expired and a timer is set to start operation on this port again.

LACP upgrade - 4: updated LACP member port detach handler

Updated #member-port #detach #handler in #LACP module. This handler #detaches the #port from the #hardware #aggregator and #inform the #remote #peer of the same. After this a wait timer is set for later processing. This procedure is executed as part of #protocol #state #changes or as a side effect of a management operation. The aggregator is detached from the member-port in hardware and the peer is informed that local end is not in sync anymore. The #collection and #distribution procedures are #disabled in #hardware and the peer will be known of the same when it receives the updated LACP PDU from local end.

LACP upgrade - 1: updated LACP aggregator and member port activation handler

Updated the port status #activation #handler for both #aggregator and the #member-port in #LACP module. The data type references has been corrected to use the new updated type. The activation handlers #cascade the #configuration #state #changes from the #LAG module to LACP module. On moving the port to #active state from LAG module, the #LACP #protocol specific procedures will be #started for these ports. Similarly on putting these ports in to #not-in-service or #not-ready state, the #protocol procedures are #stopped and #cleanup is done for these ports.

LAG upgrade - 28: added LAG interface OPER-STATUS handler

Added #aggregator logical-interface ( #lag-interface ) #OPER-STATUS #handler routine in LAG module. This enables to #perform the #support #procedures for #lag-interfaces on OPER-STATUS change. The handler is registered with the IF module and #IF #module will #execute this #call-back on respective #parameter #change in IF module. This helps to perform the necessary procedures in LAG module when the OPER-STATUS is changed from IF module. The references to the augmented custom aggregator data-structures has been updated to the standard aggregator data-structures.

LAG upgrade - 27: updating member port activation handler

Updating the #member #port #activation handler in LAG module. The references to the augmented custom member port data-structures has been updated to the standard member port data-structures. This allows to directly use the #standard #member #port data-structure and use the #embedded custom member port data-structure for internal operations. The #status related parameters are kept in the custom data-structure and on member port status #change these are updated as #active / #not-in-service. When ports are not ready to participate in the normal operations because of inconsistency in the applied configuration the state is set as #not-ready.

GMPLS update - 61: adding cross-connect out-segment based indexing

Added #out-segment based #index for #cross-connects in GMPLS module. This will enable to #access the #cross-connect entry based on it's #out-segment, #in-segment #index pair. This will help to look-up cross-connect entries from the out-segment information. This is used to #pass the #trigger to the #cross-connect on #out-segment level #changes.

GMPLS update - 39: adding out-segment interface index

Added #mpls-interface based #indexing on #out-segment configuration entries in GMPLS module. This will help in doing #search #operations among the out-segment entries for #specific #interfaces in a #quick and #efficient manner. On #interface #changes the events are #forwarded to all the segments created on the interface.

IF update - 17: adding interface create/remove handler

Added support for #logical-interface #create / #remove #handler in IF module. On #row-status #change for interfaces in IF module will #call this #handler for #perform ing the #support #procedure s in the respective module. The interface #handler has been #register ed from the #GMPLS module to complete the interface create/remove sequence for MPLS-interface s.

IF update - 14: updating logical interface stacking handler

Updated the #logical-interface #stack #handling routines in IF module. The #stacking #change #handler routines has been #upgraded for the new data-structure changes. The interface stacking change handler will #check with the #upper and #lower #interface #layer s #on #create / #remove operations for each stack slice. e.g. On adding a #TE-Link over an #ethernet port the port capability (L2/L3/MPLS, bandwidth, MTU, duplexity, etc ...) and it's current state (OPER-STATUS) is checked. On creating the TE-Link TE-Link bandwidth is deduced from the lower layer ethernet port speed/bandwidth. On removing an GMPLS / #MPLS-tunnel, the earlier reserved bandwidth is returned back to it's lower layer #MPLS-interface and #TE-Link. These operations are supported through the interface stack change handler.

The hierarchical status handler #propagate s the interface #status #from the #lower interface #layer s #to the #higher #layer s. The interface #stacking enables the interface status to be decided based on the lower layer component interfaces.

LAG logical port update - 2

Added changes in lag module for handling the #lag #aggregator #logical #interface #status #change s. Similar status handler has been added for #lag #member #port s as well. When member port status is changed in other modules (e.g. ethernet) it will cascaded to lag module. The member port status changes may cause aggregator port status change as well. This will enable lag module to perform aggregator specific operations to be performed on relation with the member port status change.
