display emdi statistics instance

Function

The display emdi statistics instance command displays statistics about an eMDI instance.

Format

display emdi statistics instance instance-id [ verbose | abnormal ]

Parameters

Parameter	Description	Value
instance-id	Specifies the ID of an eMDI instance.	The value is an integer that ranges from 1 to 5120 for S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-S, S5731S-H, S5732-H, S6720-HI, S6730-H, S6730S-H, S6730-S, and S6730S-S, and from 1 to 4112 for other models.
verbose	Displays detailed statistics about an eMDI instance.	-
abnormal	Displays exception statistics collected by an eMDI instance. For service traffic transmitted over UDP, an exception occurs if the value of RTP-LR field in the command output is not 0. For service traffic transmitted over TCP, an exception occurs if the value of UPLR or DPLR in the command output is not 0.	-
