Use this command to display detailed information about the state of upstream and 
downstream interfaces for a selected link-dependency group. The Group Transitions field 
shows a count of the number of times that the downstream interface went into its action state 
as a result of the upstream interfaces link state.

Link Local Protocol Filtering (LLPF) allows the switch to filter out multiple proprietary protocol 
PDUs, such as Port Aggregation Protocol (PAgP), if the problems occur with proprietary 
protocols running on standards-based switches. If certain protocol PDUs cause unexpected 
results, LLPF can be enabled to prevent those protocol PDUs from being processed by the 
switch.

Use this command to block LLPF protocol(s) on a port.
