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 Snooping Parameters
IGMP snooping must be enabled on both the ATM backbone
SwitchModule and the vbridge on wh ich you plan to use IGMP
snooping.
To enable IGMP snooping on the ATM Backbone SwitchModule:
Before you can enable IGMP snooping, you m ust 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 VBRIDG E 1
SET IP IP_ADDRESS <XXX.XXX .XX>.00 VBRID GE 1
SAVE ALL (This saves the address parameters for vbridge 1.)
SHOW IP (This displays the IP address you just created for vbridge 1.)
1Enable IGMP snooping on the ATM Backbone SwitchMod ule.
For example, the following command enabl es IGMP snooping on an
ATM Backbone SwitchModule in slot 9:
CB5000> set modu le 9.1 igmp_sno oping enable
2Enable IGMP snooping on a vbridge configu red on the ATM Backbone
SwitchModule .
For example, the following command enabl es IGMP snooping on
vbridge 1 on the ATM Backbone SwitchModule in slot 9:
CB5000> set vbri dge 1 igmp_snoo ping mode enab le
