3Com 5000 ATM Configuring Igmp, Snooping, CB5000 set atm slot.1 lossofsignallingdelay seconds

	If you disable automatic failover and a primary ATM OC-3 card failure
	occurs, you must use the command in step 1 to make the redundant
	ATM OC-3 card active.
	There is a configurable feature called the loss of signalling delay. The
	default is 0 seconds, and the maximum is 60 seconds. PHY failover can
	take from 0 through 60 seconds when the automatic failover feature is
	enabled. The command is:
	CB5000> set atm <slot>.1 loss_of_signalling_delay <seconds>
Configuring IGMP	IGMP snooping must be enabled on both the ATM backbone
Snooping	SwitchModule and the vbridge on which you plan to use IGMP
Parameters	snooping.
	To enable IGMP snooping on the ATM Backbone SwitchModule:
	Before you can enable IGMP snooping, you must set up an IP address
	for each vbridge that is configured on the ATM Backbone
	SwitchModule. You must setup a subnet mask before you can assign
	an IP address. The correct commands are:
	SET IP SUBNET_MASK <FF.FF.FF>.00 VBRIDGE 1
	SET IP IP_ADDRESS <XXX.XXX.XX>.00 VBRIDGE 1
	SAVE	ALL	(This saves the address parameters for vbridge 1.)
	SHOW	IP	(This displays the IP address you just created for vbridge 1.)
1	Enable IGMP snooping on the ATM Backbone SwitchModule.
	For example, the following command enables IGMP snooping on an
	ATM Backbone SwitchModule in slot 9:

CB5000> set module 9.1 igmp_snooping enable

2Enable IGMP snooping on a vbridge configured on the ATM Backbone SwitchModule.

For example, the following command enables IGMP snooping on vbridge 1 on the ATM Backbone SwitchModule in slot 9:

CB5000> set vbridge 1 igmp_snooping mode enable
