| Tunnel IP Address/CIDR | (Required)
Type the IP Address for the tunnel (CIDR). |
| Gateway | (Optional)
Type the IP address of the gateway. |
| VRRP Router ID | (Required)
Type 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. |
| Native VLAN ID | (Required)
Type the Native VLAN ID. The Native VLAN is untagged. |
| Device Tunnel Concentrator | (Required—Primary and Backup)
Select a primary Tunnel Concentrator from the menu. Select a backup Tunnel Concentrator from the menu. |
| Tunnel Port | (Required—Primary and Backup)
Select a port for the tunnel from the menu for the primary Tunnel Concentrator from the menu. Select a port for the tunnel from the menu for the backup Tunnel Concentrator from the menu. |
| VLAN ID | (Required—Primary and Backup)
Type the VLAN ID for the primary and for the backup Tunnel Concentrators. (Optional) For an untagged VLAN, select the corresponding check box. |
| IP Address | (Required—Primary and Backup)
Type the IP address for the primary and the backup Tunnel Concentrators. |
| Bridge Port | (Required—Primary and Backup)
Select a bridge port for the tunnel from the menu for the primary Tunnel Concentrator. Select a bridge port for the tunnel from the menu for the backup Tunnel Concentrator. |
| AP Keepalive Interval (seconds) | Specifies the interval at which the AP sends keepalive messages to the primary and backup tunnel concentrators. The AP sends keepalive only to tunnels that are not in use and listens for a response from each tunnel concentrator independently. If the AP receives a response, it sets the tunnel status to Active. If no response is received within the interval, the AP retries the keepalive based on the configured AP Keepalive Retries value. Possible values: 1 to 60 seconds Default: 3 seconds |
| AP Keepalive Retries | Specifies
the maximum number of retry attempts for a failed keepalive before the AP
changes the tunnel status to Inactive for the primary or backup tunnel
concentrator. If the AP does not receive a keepalive response within the configured interval, it retries until the maximum retry count is reached. When the retry limit is exceeded, the AP marks the tunnel as Inactive. If a response is later received, the AP changes the tunnel status to Active and resets the retry count. Possible values: 1 to 10 retries Default: 5 retries |
| To add or edit broadcast or multicast control for the Tunnel Concentrator service, select Broadcast/Multicast Control. | |
