Chapter 2 Cisco IOS Commands for the Catalyst 4500 Series Switches
Examples This example shows how to configure the global robustness variable so that the switch sends out three
queries before it deletes a listener port that does not respond:
Switch# configure terminal
Enter configuration commands, one per line.
Switch(config)# ipv6 mld snooping robustness-variable 3
Switch(config)# end
Switch#
This example shows how to configure the robustness variable for VLAN 1. This value overrides the
global configuration for the VLAN:
Switch# configure terminal
Enter configuration commands, one per line.
Switch(config)# ipv6 mld snooping vlan 1 robustness-variable 1
Switch(config)# end
Switch#
You can verify your settings by entering the show ipv6 MLD snooping [vlan vlan-id] user EXEC
command.
