IBM SG24-4817-00 manual Ospf MIB

This soft copy for use by IBM employees only.

This group contains configuration and state information of a bi-directional VCL. Here VCs can be created, deleted or modified here. Also, information can be found on the AAL that is in use on a VC specific information can be found if AAL5 is used, such as the type of data encapsulation.

−The Virtual Path (VP) Cross Connect Group

This group contains configuration and state information of all

point-to-point and point-to-multipoint VP cross connects. In other words, it gives information on the VP swapping table. With this group VP cross-connects can be established and removed.

−The Virtual Channel (VC) Cross Connect Group

This group performs the same functions as in the VP cross connect group but for the VCs.

−The AAL5 Virtual Channel Connection Performance Statistics Group This group contains the AAL5 performance statistics of a VCC.

•OSPF MIB

Since the TRS function uses OSPF with very few modifications to the original code, the IBM 8285 ATM network supports the OSPF MIB (RFC 1253) unchanged.

•ILMI MIB

This MIB is defined by The ATM Forum in the UNI specification. Following is a brief description of the groups defined in these MIBs:

−Physical Port Group

This group gives information on a particular port such as the status, transmission types and cable type.

−ATM Layer Group

This group has the maximum number of supported VPs and VCs on the UNI, the number of VPs and VCs configured on the UNI and the number of active VP and VC bits on the interface.

−ATM Statistics Group

Here you will find the number of cells received, dropped and transmitted on the UNI.

−Virtual Path Group

This group gives information on the VPs on the UNI. This includes status, traffic shaping, policing and QoS parameters.

−Virtual Channel Group

This group performs the same functions as the virtual path group but for the VCs.

−Network Prefix Group

This group has information on the network prefix in use on the user side of the UNI and its validity.

−Address Group

This group has information on the ATM address in use on the user side of the UNI and its validity.
