3Com MSR 50, MSR 30 manual Stp cost

611

Use the undo stp config-digest-snoopingcommand to disable Digest

Snooping.

The feature is disabled by default.

Notice that:

■You need to enable this feature both globally and on ports connected to other vendors’ devices to make it take effect. It is recommended to enable the feature on all associated ports first and then globally, making all configured ports take effect at the same time to minimize the impact, and disable the feature globally to disable it on all associated ports.

■It is not recommended to enable Digest Snooping on the MST region edge port to avoid loops.

■Refer to “Link Aggregation Configuration Commands” on page 473 for information about port groups.

Examples # Enable global Digest Snooping.

<Sysname> system-view

[Sysname] stp config-digest-snooping

# Enable Digest Snooping on Ethernet 1/1.

<Sysname> system-view

[Sysname] interface ethernet 1/1

[Sysname-Ethernet1/1] stp config-digest-snooping

stp cost

Syntax	stp [ instance instance-id] cost cost
	undo stp [ instance instance-id] cost
View	Ethernet interface view, port group view
Parameters	instance instance-id: Sets the path cost of the port(s) in a particular MST instance.
	The minimum value of instance-idis 0, representing the CIST, and the maximum
	value of instance-idis 15.
	cost: Path cost of the port, the effective range of which depends on the path cost
	calculation standard adopted.
Description	Use the stp cost command to set the path cost of the port(s) in the specified MST
	instance or all MST instances.
	Use the undo stp cost command to restore the default.
	By default, the device automatically calculates the path costs of ports in each MST
	instance based on the corresponding standard.
	Note that:
