lpEngArcAqmMaxVirtualLinks 1.3.6.1.4.1.562.2.4.1.12.23.5.4.10.1.10

This attribute indicates the maximum number of virtual links (VLs) that can exist on this AQM. Normally a virtual link contains all VCCs and VPCs provisioned for a port (OC-3, DS3, E3, etc), making a virtual link equivalent to a port. However, if an AtmIf linked to a port has provisioned virtual path terminations (VPTs) with a vptType of virtualLink, then there is one virtual link per VL VPT, and one virtual link for all remaining VCCs and VPCs not part of a VL VPT. Unless this attribute is overridden in the optional Override subcomponent, its value will be sameNumberAsPorts, indicating that there is one virtual link per port using the AQM. The value of maxVirtualLinks may restrict the maximum bandwidth allowed per virtual link. If the value of this attribute is sameNumberAsPorts there is no restriction on a virtual link's bandwidth; it may be any cell rate up to the port's link rate. If maxVirtualLinks is set to some other value, then all virtual links on the AQM are subject to a maximum cell rate, listed in the table below, which may be less than the port cell rate. maxVirtualLinks : cell rate 6: 163840 cell/s 14 : 81920 cell/s 29: 40960 cell/s On 2pOC3MmAtm2 and 2pOC3SmAtm2 cards, there is one AQM per port. Since one link is required for connections not part of a VL VPT, if maxVirtualLinks is 6 (for example), then up to fiveVL VPTs may be provisioned on the port. Continuing this example, each VPT's provisioned bandwidth can be no larger than 163840 cells/s (46% of the total OC-3 rate) and the total bandwidth available to independent VCCs and non VL VPTs will be no greater than 163840 cell/s. On 3pDS3Atm2 and 3pE3Atm2 cards, there is one AQM for the card. Since three links are required for connections not part of a VL VPT (one per port), if maxVirtualLinks is 6 (for example), then up to threeVL VPTs may be provisioned on the card. In this case, since the maximum cell rate per virtual link is 163840 cell/s, which is greater than the port cell rate for both DS3 and E3, there is no restriction on the bandwidth assigned to VL VPTs or available to independent VCC and non VL VPT connections.
