Description
IGMP querier
Uses the switch to send periodic query packets to multicast groups to
avoid multicast traffic loss
Multicast flood blocking
Blocks multicast flooding from unknown sources
Router Port
Specifies which ports to use as the router port for the switch
After receiving an IGMP packet, QSS forwards the control packets
through the selected router ports.
Note
If you do not specify a router port, QSS automatically
assigns a port to be used as a router port.
Fast Leave
Specifies the ports that support Fast Leave
After receiving an IGMP leave message, QSS stops forwarding specific
multicast traffic to the selected Fast Leave ports.
5. Click Save.
QSS saves the IGMP snooping settings.
Managing access control list (ACL) entries
Access control lists allow you to handle network traffic in a switch by using controlled rule sets. Each ACL rule
is a user-created set of conditions that the switch uses to determine whether a data packet can pass through
the network. If the data packet matches an existing ACL rule, the switch then uses the rule to determine
whether to permit or deny the packet. If there is no matching ACL rule or there are no ACL rules, the switch
applies a default rule.
You can use ACLs to control host access to different parts of a network or to control traffic forwarding or
blocking at the switch level.
Adding an IP address–based ACL rule
1. Log in to QSS.
2. Go to Configuration > ACL > By IP Address .
3. Click Add.
The Add ACL - IP Address window opens.
4. Configure the ACL settings.
