Function

The display cluster channel status command displays the status of cluster channels.

The display cluster channel status verbose command displays detailed cluster channel status statistics.

Format

display cluster channel status

display cluster channel status verbose [ backup | forward | negotiation ] [ node-id ]

Parameters

Parameter	Description	Value
backup	Indicates the backup channel.	-
forward	Indicates the forwarding channel.	-
negotiation	Indicates the negotiation channel.	-
node-id	Specifies the ID of a member in the cluster.	The value is an integer ranging from 1 to 8.

Both TCP and UDP protocols are used in managementplane channel detection.
 TCP channel is used for managementplane data backup.
 UDP channel is used for negotiation.
Delay below 3 seconds is negligible.
