trk Pa Max Lc

This attribute indicates the number of Logical Channels (LCh/n) supported on this trunk. This attribute is used to allocate memory on the trunk FP for the PORS forwarding tables.Unless running in mapped mode on ATM hardware, the PathAdmin will add 100 channels to maxLc to reduce the chances of allocation clashes. However, you should never see more than maxLc channels in use for any extended period of time. On ATM hardware in mapped mode the PathAdmin will only add 10 channels to maxLc to permit more efficient use of the available VCC space. The PathAdmin may not be able to honor a request for maxLc channels. This will happen when the neighbor PathAdmin asks for less channels than this PathAdmin. To resolve the conflict the PathAdmin will always pick the minimum of the two maxLc values. This minimum value is called the negotiatedMaxLc and can be viewed as an operational parameter of the PathAdmin. Note that in mapped mode on ATM hardware, the value of this attribute provides an upper bound to the number of VCCs that this Trunk/n PathAdmin can occupy. It is not a guarantee that maxLc VCCs will be available to this PathAdmin because the VCC space is a shared resource on the card or port.
