Multiple Ethernet Uplink

Instant APs support the configuration of multiple Ethernet Ethernet is a network protocol for data transmission over LAN. ports for uplink connection. One Ethernet Ethernet is a network protocol for data transmission over LAN. port assumes the role of active uplink port while the other Ethernet Ethernet is a network protocol for data transmission over LAN. port is used as a backup uplink port. Ports configured as uplink ports are enabled with reachability detection to identify the better uplink connection between them. Failover and pre-emption features are enabled by default when multiple Ethernet Ethernet is a network protocol for data transmission over LAN. uplink is configured.

Important Points to Remember

Configuring multiple Ethernet Ethernet is a network protocol for data transmission over LAN. uplink has the following limitations:

• Supported only in standalone and mesh deployments with a single mesh portal.
• Does not support multiple PPPoE Point-to-Point Protocol over Ethernet. PPPoE is a method of connecting to the Internet, typically used with DSL services, where the client connects to the DSL modem. connections.
• Does not support static IP uplink.

Configuring Multiple Ethernet Uplink

As Instant APs support layer 2 redundancy in APs with two Ethernet Ethernet is a network protocol for data transmission over LAN. uplinks, both the Eth0 and Eth1 ports are bonded together virtually as bond0. Therefore before configuring multiple Ethernet Ethernet is a network protocol for data transmission over LAN. uplink, the Eth1 port must be removed from this virtual bond, bond0. To remove Eth1 port from the bond0, change the operation mode of Eth1 to downlink. Read more on how to change the operation mode of the Eth1 port in Configuring the Operation Mode of Ethernet Ports section.

To configure multiple ethernet uplink for an Instant AP, perform the following workflow:

1. Configure a wired port profile for the second Ethernet Ethernet is a network protocol for data transmission over LAN. uplink. See Configuring a Wired Profile to learn how to configure a wired port profile.

   The following CLI Command-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions. command configures a wired port profile:

   (Instant AP)(config)# wired-port-profile <profile name>
   

2. Assign an ID for native-vlan and set the port-type to wan in the wired port profile.

   The following CLI Command-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions. commands configure the native-vlan and port-type in the wired port profile:

   (Instant AP)(config)# wired-port-profile <profile name>

   native-vlan <vlan Virtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN. number>

   port-type <wan , lan>

3. Assign the profile configured for uplink to an Ethernet Ethernet is a network protocol for data transmission over LAN. port. See Assigning a Profile to Ethernet Ports to learn how to assign a wired port profile to an Ethernet Ethernet is a network protocol for data transmission over LAN. port.

   The following CLI Command-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions. command assigns a port profile to the Ethernet Ethernet is a network protocol for data transmission over LAN. port:

   (Instant AP)(config)#enetX-port-profile <wired port profile>

4. Configure DHCP Dynamic Host Configuration Protocol. A network protocol that enables a server to automatically assign an IP address to an IP-enabled device from a defined range of numbers configured for a given network.  settings for the VLAN Virtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN. interface.

   The following CLI Command-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions. command configures DHCP Dynamic Host Configuration Protocol. A network protocol that enables a server to automatically assign an IP address to an IP-enabled device from a defined range of numbers configured for a given network.  settings for the VLAN Virtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN. interface:

   (Instant AP)(config)#interface vlan Virtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN. <vlan Virtual Local Area Network.

   ip address dhcp-client

5. Enforce uplink-enforce-wired-port-vlan-setting on the AP. See Configuring Wired Port Profile Settings for Uplink Port to learn how to enforce a wired port profile on an Ethernet Ethernet is a network protocol for data transmission over LAN. port.

   The following CLI Command-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions. command configures DHCP Dynamic Host Configuration Protocol. A network protocol that enables a server to automatically assign an IP address to an IP-enabled device from a defined range of numbers configured for a given network.  settings for the VLAN Virtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN. interface:

   (Instant AP)(config)#uplink-enforce-wired-port-vlan-setting

6. Configure the priority for the uplink ports using the uplink command. See Setting an Uplink Priority to learn how to priority for Ethernet Ethernet is a network protocol for data transmission over LAN. uplink ports.

   The following CLI Command-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions. commands configure the priority of uplink interfaces:

   (Instant AP)(config)#uplink

   uplink-wired vlan Virtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN. <ID> priority <priority level>

   uplink-wired vlan Virtual Local Area Network.

Verifying Configuration

Use the following commands to verify the uplink configuration:

• show IP interface brief and show ip interface detail command to view interface information.
• show uplink status command to view uplink status information.
