Chapter 5: Setting Up SafeGuard Switches
(SafeGuardOS) #configure terminal
(SafeGuardOS) (config) #igmpsnooping maximum-response-time 15
(SafeGuardOS) (config) #exit
(SafeGuardOS) #
To verify the configuration, use the Privileged Exec show igmpsnooping command. This
command is described further in Showing the IGMP Snooping Configuration on page 172.
Per VLAN
To set the maximum response time by VLAN, in VLAN database mode use the
igmpsnooping vlan maximum-response-time command. Use the no version of the
command to return the setting to the default value.
igmpsnooping vlan vlanid maximum-response-time seconds
no igmpsnooping vlan vlanid maximum-response-time
The following example sets interfaces on VLAN 2 to have a maximum response time of
15 seconds:
(SafeGuardOS) #configure terminal
(SafeGuardOS) (config) #vlan database
(SafeGuardOS) (Vlan) #igmpsnooping vlan 2 maximum-response-time 15
(SafeGuardOS) (Vlan) #exit
(SafeGuardOS) (config) #exit
(SafeGuardOS) #
To verify the configuration, use the Privileged Exec show igmpsnooping command. This
command is described further in Showing the IGMP Snooping Configuration on page 172.
Setting the Multicast Router Expiration Time
This optional configuration step is available both globally and for VLANs. The multicast
router expiration time is the amount of time in seconds that the switch waits for a query
to be received on an interface before the interface is removed from the list of interfaces
with multicast routers attached. The valid range is between 0 to 3600 seconds. A value of
0 indicates that the timer never expires, which is the default.
Syntax Description vlanid Sets the maximum response time on a VLAN
having this identification number. Valid
assignment numbers are from 1 to 4094.
seconds Sets the maximum response time in seconds on
a VLAN for queries sent after not receiving a
report. Valid ranges are from 1 to 3599 seconds
and must be less than the IGMP query interval
time value. The default is 10 seconds.
