passiveStp

Description: Enables, disables, or displays the status of Passive Mode Spanning Tree on the device.

Passive Mode Spanning tree allows ports on leaf bridges to transition very quickly and not invoke a global network re-span through requesting root elections by:

•Not allowing switches to become the root node;

•Not allowing switches to send configuration BPDUs;

•Expiring the message age timer when a link transitions to a down state;

•Moving the 802.1D Blocked state directly to forwarding; and

•Using a default or locally defined Passive STP Max Age time.

Syntax:	passiveStp [ enable disable status ]

Options:	enable – Enables PassiveStp on this device.
	disable – Disables PassiveStp on this device.
	status – Indicates the current status of Passive STP.

Examples:	->PassiveStp disable
	Disabled
	->PassiveStp status
	Passive is disabled
	Passive Maxage = 2000

ping

Description:	Generates an outbound ping request to check the status (alive/not alive) of a
	device at a specified IP address.

Syntax:	ping [IP address]

Options:	IP address — Specifies the IP address to ping.

Example:	->ping 122.144.40.10
	122.144.40.10 is alive
