network

You can configure the network interface settings, including link mode for speed and duplex, MAC address, Maximum Transmission Unit (MTU) and Maximum Segment Size (MSS) values, and LAG interface options.

Command

set network

Syntax

set network
interface-link [PortID] [linkmode] [1000fd|100fd|100hd|10fd|10hd|auto] [autoneg] [on|off] [fecmode]
macaddr [PortID] [default] [override] [<MAC address>]
mtu-mss [PortID] [mtu ] [<number value>|default] [mss] [<number value>|default]
lag-interface [interface_name] [lag-mgt] [active-backup] [auto] [Port] [lacp] [lacp-rate] [fast|slow] [static-mode] [enable|disable] [xmit-hash-policy] [layer2|layer2+3|layer3+4] [link-mgt] [down-delay] [<value>] [garp-count] [<value>] [monitor-interval] [<value>] [up-delay] [<value>]

Options

interface-link [PortID] [linkmode] [1000fd|100fd|100hd|10fd|10hd|auto] [autoneg] [on|off] [fecmode]

Set the interface speed in Mbps and duplex as either full or half. You can use the auto option to automatically negotiate the speed and duplex with the connected device. You can turn autoneg on or off for link parameters other than link speed and duplex. Additionally, you can select a Forward Error Correction (FEC) mode for the interface. FEC modes depend on the appliance model.

macaddr [PortID] [default] [override] [<MAC address>]

Set the MAC address of the interface. The default option keeps the existing MAC address. If you're using the override option to override the default MAC address, enter the new MAC address manually.

mtu-mss [PortID] [mtu] [<number value>|default] [mss] [<number value>|default]

Set the MTU and MSS for physical interfaces. Default values are as follows:

  • MTU: 1500
  • MSS: 1460
lag-interface [interface_name] [lag-mgt] [active-backup] [auto] [Port] [lacp] [lacp-rate] [fast|slow] [static-mode] [enable|disable] [xmit-hash-policy] [layer2|layer2+3|layer3+4] [link-mgt] [down-delay] [<value>] [garp-count] [<value>] [monitor-interval] [<value>] [up-delay] [<value>]

Configure the settings for any lag interfaces. The available ranges are as follows:

  • down-delay: 0-10000 milliseconds
  • garp-count: 0-255
  • monitor-interface: 0-10000 milliseconds
  • up-delay: 0-10000 milliseconds
