The following table describes the fields in the Tunnel Concentrator Service configuration. Note that each field is a required configuration, unless specified otherwise.
| Field | Description |
|---|---|
| Name | Enter a name for the Tunnel Concentrator Service. |
| Description | (Optional) Enter a description for the Tunnel Concentrator Service. |
|
Single Tunnel Concentrator Redundant Tunnel Concentrator | Select one of these options only:
|
| Tunnel IP Address/CIDR | Enter the IP address and network mask
to which APs should direct tunneled traffic (for example,
10.10.10.3/24). Note that address functionality differs
depending on whether or not you configured High Availability:
|
| Gateway | (Optional) Enter the address of the default gateway. |
| VRRP Router ID | (Redundant Tunnel Concentrator only)
Enter the ID for the VRRP router. ExtremeCloud IQ configures the same VRRP Router ID for both the primary and backup Tunnel Concentrators (range 1-255). The VRRP Router ID must be different for each cluster of VRRP devices. In addition, the ID must be different than the VRRP Router IDs that were configured on the data ports for the individual Tunnel Concentrator instances. |
| Native VLAN | Enter the Native VLAN ID. This VLAN is untagged. |
|
Note: The fields in
this section are relevant to a specific instance of Tunnel
Concentrator. If you selected Redundant Tunnel
Concentrator Service, these fields appear
twice because the service includes a pair of instances. In
this case, complete the fields separately with values that
are relevant to each instance.
| |
| Device Tunnel Concentrator | From the drop-down, select a specific Tunnel Concentrator device instance to assume this role in the service. |
| Tunnel Port | From the menu, select a port for the tunnel for this Tunnel Concentrator instance. If you are deploying LAG on this Tunnel Concentrator, select a LAG port. |
| VLAN ID | Select the tunneling VLAN ID for this Tunnel Concentrator instance. If the VLAN is untagged, select Untagged. |
| IP Address | (Redundant Tunnel Concentrator only) Enter an IP address to act as tunnel termination point for this instance in the HA pair. Data that goes from the AP to the Tunnel IP Address gets redirected to this IP Address when this Tunnel Concentrator is active. |
| Bridge Port | From the menu, select a bridge port for the tunnel for this Tunnel Concentrator instance. If you are deploying LAG on this Tunnel Concentrator instance, you may select a LAG port, although it's not mandatory. |
| Broadcast/Multicast Control | |
| Permitted Multicast IP Addresses | This section provides access rules for
multicast packets that cross this Tunnel Concentrator serivce,
based on the multicast address. The service allows multicast
packets where the multicast destination is permitted by an
assigned rule and discards multicast packets where none of the
assigned rules permit multicast packets to that address. To add a multicast rule to this service, select one of the following options:
Within each rule, the IP Address field identifies either a specific IP address (e.g., 224.0.0.5) as a multicast destination, or a network address (e.g., 224.0.0.0/5) for a range of allowed addresses. If you enter a network address, Tunnel Concentrator allows multicast packets where the destination multicast address is encompassed by that range. To remove a rule from your control list,
select the adjacent |
| Block Non-Essential Broadcast | When this setting is selected (the default setting), the Tunnel Concentrator service blocks broadcast traffic, except for ARP and DHCP traffic. When this setting is not selected, the Tunnel Concentrator service floods broadcast traffic to all APs. |
| ARP Proxy | When this setting is selected (the default setting), the Tunnel Concentrator service maintains an ARP table and can proxy and respond to ARP requests. When this setting is not selected, Tunnel Concentrator floods ARP requests to all APs. |
Note
The Broadcast/Multicast Control section covers how the Tunnel Concentrator service handles broadcast and multicast traffic that crosses Tunnel Concentrator. Additional broadcast and multicast configurations that you apply throughout your network impact the amount of broadcast and multicast traffic that attempts to cross Tunnel Concentrator.When you have completed your configuration, select Save.
