Chapter 2 Cisco IOS Commands for the Catalyst 4500 Series Switches
ipv6 mld snooping robustness-variable
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. End with CNTL/Z.
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. End with CNTL/Z.
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.
