Turn off the Gaia computer:

• In Gaia Portal:

  Click Maintenance > Shut Down, and click Halt

• In Gaia Clish:

  Run: halt

2

Add, remove, or replace the interface cards.

3

Turn on the Gaia computer.

1

In the navigation tree, click Network Management > Network Interfaces.

2

Select an interface from the list and click Edit.

3

Select the Enable option to set the interface status to UP.

4

In the Comment field, enter the applicable comment text (up to 100 characters).

5

On the IPv4 tab, do one of these:

• Select Obtain IPv4 address automatically to get the IPv4 address from the DHCPv4 server.
• Enter the IPv4 address and subnet mask in the applicable fields.

6

On the IPv6 tab (optional), do one of these:

• Select Obtain IPv6 address automatically to get the IPv6 address from the DHCPv6 server.
• Enter the IPv6 address and mask length in the applicable fields.

Important - First, you must enable the IPv6 Support and reboot. R80.20 does not support IPv6 Address on Gaia Management Interface (Known Limitation 01622840).

7

On the Ethernet tab:

• Select Auto Negotiation, or select a link speed and duplex setting from the list.
• In the Hardware Address field, enter the Hardware MAC address (if not automatically received from the NIC).

  Caution: Do not manually change the MAC address unless you are sure that it is incorrect or has changed. An incorrect MAC address can lead to a communication failure.

• In the MTU field, enter the applicable Maximum Transmission Unit (MTU) value (minimal value is 68, maximal value is 16000, and default value is 1500).
• Select Monitor Mode, if needed. For configuration procedure, see the R80.20 Installation and Upgrade Guide.

8

Click OK.

interface <Name of Physical Interface>

Specifies a physical interface.

auto-negotiation {on | off}

Configures automatic negotiation of interface link speed and duplex settings:

• on - Enabled
• off - Disabled

comments "Text"

Configures an optional free text comment.

• Write the text in double-quotes.
• Text must be up to 100 characters.
• This comment appears in the Gaia Portal and in the output of the show configuration command.

ipv4-address <IPv4 Address>

Configures the IPv4 address.

ipv6-address <IPv6 Address>

Configures the IPv6 address.

Important - First, you must enable the IPv6 Support and reboot. R80.20 does not support IPv6 Address on Gaia Management Interface (Known Limitation 01622840).

subnet-mask <Mask>

Configures the IPv4 subnet mask using dotted decimal notation (X.X.X.X).

mask-length <Mask Length>

Configures the IPv4 or IPv6 subnet mask length using the CIDR notation (integer between 2 and 32).

ipv6-autoconfig {on | off}

Configures if this interface gets an IPv6 address from a DHCPv6 Server:

• on - Gets an IPv6 address from a DHCPv6 Server
• off - Does not get an IPv6 address from a DHCPv6 Server (you must assign it manually)

Important - First, you must enable the IPv6 Support and reboot.

link-speed {10M/half | 10M/full | 100M/half | 100M/full | 1000M/full | 1000M/full}

Configures the interface link speed and duplex status.

Available speed and duplex combinations are:

• 10M/half
• 10M/full
• 100M/half
• 100M/full
• 1000M/full
• 10000M/full

mac-addr <MAC Address>

Configures the hardware MAC address.

monitor-mode {on | off}

Configures Monitor Mode on this interface:

• on - Enabled
• off - Disabled

Default: off

For configuration procedure, see the R80.20 Installation and Upgrade Guide.

mtu <68-16000 | 1280-16000>

Configures the Maximum Transmission Unit size for an interface.

For IPv4:

• Range: 68 - 16000 bytes
• Default: 1500 bytes

For IPv6:

• Range: 1280 - 16000 bytes
• Default: 1500 bytes

rx-ringsize <0-4096>

Configures the receive buffer size.

• Range: 0 - 4096bytes
• Default: Depends on the interface driver

state {on | off}

Sets the interface state:

• on - Enabled
• off - Disabled

tx-ringsize <0-4096>

Configures the transmit buffer size.

• Range: 0 - 4096 bytes
• Default: Depends on the interface driver
