Overview

Fast Path LAG provides bonding, or LAG, support in the fast path.

Features

  • Supported algorithms:

    • balance-rr mode (Round-robin policy)

    • active-backup mode (use the active-slave interface to send packets)

    • balance-xor mode (xor policy)

    • 802.3ad mode IEEE (802.3ad Dynamic link aggregation)

    • flow hash computed from Ethernet protocol, vlan ID, IP addresses, L4 protocols and ports out of the most inner packet inside Ethernet, VLAN, IPv4, IPv6, IP tunnels, GRE.

  • Supported hash policies (only for balance-xor and 802.3ad):

    • layer2 xmit hash policy

    • layer2+3 xmit hash policy

    • layer3+4 xmit hash policy

    • encap2+3 xmit hash policy

    • encap3+4 xmit hash policy

  • Manage LAG interfaces:

    • Displaying LAG interfaces and their slaves.

    • Create a LAG interface.

    • Delete a LAG interface and its links to slave interfaces.

    • Link a LAG interface (master) to another interface (slave).

    • Unlink an interface (slave) from a LAG interface (master).

    • Set the LAG policies. The default is balance-rr (round robin).

    • Set the LAG xmit hash policy (default is layer2).

  • Compatibility with VRF processing.

  • NUMA awareness
