VLAN Advanced Setting

Configure the following parameters to optimize your network connectivity. Modifying the following settings is optional. Consider changes thoughtfully.

Note

For higher transmission rates, by default, multicast is converted to unicast for all access points discovered by ExtremeCloud IQ Controller that support Wi-Fi 6 and higher standards.

There is a maximum client threshold of 64 clients. Above 64 clients, the AP defaults to broadcasting on a DTIM interval.

Multicast Bridging

Select this option to enable forwarding of multicast traffic (point-to-multipoint) between the wired and wireless sides of the AP. Because multicasts consume a lot of 802.11 air time, when you enable this option you must also specifically identify the types of multicast traffic that you want forwarded by adding one or more rules.

Multicast Rules

Add one or more multicast rules if you enabled Multicast Bridging. Multicast rules (point-to-multipoint) permit traffic that matches the rule. A multicast rule is defined as the multicast IP address of the traffic destination and a mask that allows a range of addresses to be matched by a single rule. ExtremeCloud IQ Controller offers a predefined set of multicast rules. Select a preset multicast rule or define a new rule.

Block Non-Essential Broadcast

When enabled, block non-essential broadcast traffic on a bridged at controller (B@AC) topology.

This setting overrides user-level policy role definitions:

When the network policy is Allow All, all broadcast traffic except ARP and DHCP on a topology is blocked in both directions. ARP and DHCP broadcast traffic is considered essential.
When the network policy is Deny All, all inbound traffic is blocked. Outbound ARP and DHCP traffic is forwarded. All other outbound traffic is blocked.
