vismAal2SubcellMuxing
Module: CISCO-VISM-MODULE-MIB
OID (symbolic): CISCO-VISM-MODULE-MIB::vismAal2SubcellMuxing
OID (numeric): 1.3.6.1.4.1.351.110.3.17.6.1
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: This object is a card level parameter for AAL2 adaptation and it identifies the mutiplexing function of the AAL2 CPS(Common Part Sub-layer). When it is disabled then each CPS-Packet would fill only one or two cells with padding (Partial fill cells) Note that the length field for each CPS-Packet can be up to 64bytes. When this option is enabled then mutiple streams of CPS-Packets are mutiplexed to a single ATM connection without partial fill unless there is time-out. Refer to ITU-T I.363.2 for more information.
When the muxing type changes if CIDs are present, then we need to check for CAC voilation for all CIDs, if the CAC fails then the change request will be rejected else the muxing status will be changed and the vismAal2MuxingTrap will be sent and the card will be reset . All the existing connecitons will come up in new muxing type.
when the muxing type changes while there are no CIDs then the card will NOT be reset, but the vismAal2MuxingTrap will be sent.
What is vismAal2SubcellMuxing?
This read-write TruthValue is a card-level AAL2 adaptation setting that controls the CPS (Common Part Sub-layer) multiplexing function: disabled means each CPS-Packet fills only one or two cells with padding, enabled means multiple CPS-Packet streams are multiplexed onto a single ATM connection. An admin cares because enabling subcell muxing improves cell-fill efficiency for AAL2 traffic at the cost of added multiplexing complexity, directly affecting bandwidth utilization on the card. For example, an operator trying to reduce ATM cell overhead for many low-bandwidth AAL2 voice channels would enable this to multiplex multiple CPS-Packet streams per connection.
