New Features
This release introduces the following features:
- Broadcast and Multicast Controls
- To help you manage the flow of traffic that crosses
Tunnel Concentrator, configure settings that allow or deny broadcast and
multicast traffic thereby avoiding packet loss when traffic is at its peak.
The following options are available:
- With broadcast traffic, configure Tunnel
Concentrator to block non-essential broadcast traffic. When this
option is selected, only ARP and DHCP broadcast traffic is forwarded
(this option is enabled by default). When this option is deselected,
Tunnel Concentrator floods broadcast traffic to all APs.
- With multicast traffic, assign rules that allow
multicasting for specific multicast addresses. Tunnel Concentrator
forwards multicast traffic only if a rule has been assigned that
allow that allows multicasting to that address.
You can configure broadcast and multicast control
as follows:
- With ExtremeCloud IQ-managed deployments,
configure broadcast and multicast control using the Tunnel Concentrator
Service configuration on ExtremeCloud IQ
(Classic).
- With ExtremeCloud IQ Controller-managed
deployments, configure broadcast and multicast controls using
Advanced settings for the VLAN with
the GRE topology configuration that Tunnel Concentrator
uses.
- ARP Proxy Disablement from ExtremeCloud IQ
- ARP Proxy can now be disabled for Tunnel Concentrator
deployments that are managed by ExtremeCloud IQ. An ARP Proxy check box has
been added to the Tunnel
Concentrator Service configuration on ExtremeCloud IQ
(Classic). The setting is enabled by default, but you can turn the feature
off by deselecting the option.

Note
This option is not available for Tunnel
Concentrator deployments that are managed by ExtremeCloud IQ
Controller.
- Combined Packet Capture Files
- The Packet Capture feature has been simplified by
combining captures for the Bridging and Listening interfaces into a single
packet capture file. This update makes troubleshooting easier as there is no
longer a need to manage packet captures separately for each interface.
