frChanCnfChangeCount
Module: CISCO-WAN-AXIPOP-MIB
OID (symbolic): CISCO-WAN-AXIPOP-MIB::frChanCnfChangeCount
OID (numeric): 1.3.6.1.4.1.351.110.5.1.2.1.1.1.64
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: This object is added only for FRSM12 card.
This counter tracks the number of configuration changes that happen on a channel. The counter is associated only with the end point and NOT with the connection itself.
This counter is used by the NMS to determine if a connection configuration had been modified and requires an upload. This functionality is conventionally achieved by time stamping using a time-of-day clock. However, in switches where time-of-day clock is not available, the following scheme is used:
The upload counter is incremented, when:
* assignment of connection to an end point channel. This happens when a connection is added and assigned this channel number. * de-assignment of connection from a channel number. This happens when a connection is deleted and the end point resource is released. * When there is a configuration change done to the connection that is associated with this end point channel number.
In a new system, an unutilised resouce (channel number) has a counter value of zero. When a connection is added to this channel end point, the counter is incremented. And is incremented for any of the above operations. When a connection is deleted the value of this counter is incremented and preserved till a new connection gets associated with this channel end point.
This object is not applicable to MGX Release 1.x.
What is frChanCnfChangeCount?
This read-only Counter, added specifically for the FRSM12 card, tracks the number of configuration changes made to a channel end-point, tied to the end-point itself rather than to the connection as a whole. Network management systems poll this counter, instead of relying on time-of-day timestamps (which are not always available on the switch), to detect that a connection's configuration was modified and therefore needs to be re-uploaded. For example, an NMS periodically comparing its cached frChanCnfChangeCount value against the live counter on an FRSM12 channel would know to re-fetch that channel's configuration as soon as the two values diverge.
