Figure 2-4. LMI Statistics for a Frame Relay Connection
On a functioning Frame Relay connection, the polls sent and received should
be approximately equal. The Frame Relay interface in Figure 2-4 has sent 17
polls without receiving a reply. Steadily increasing polls sent out without
replies probably indicate:
incompatible signaling type
incorrect signaling role
incorrect DLCI (also indicated by a deleted PVC)
mismatched DS0 or E0 channels
Table 2-2 gives the command syntax for displaying information about Frame
