NOTE
TCP or UDP Destination and Source port is used under the following conditions:
– Packet is non-fragmented and without option, and packet is a TCP or UDP packet
– or the load-balance force-l4-hashing command is configured.
• Layer-2 packets with an MPLS payload: source MAC address and destination MAC address,
VLAN ID, Inner VLAN ID (for double-tagged packets), Ethertype, and up to 3 MPLS Labels.
NOTE
For double-tagged packets, Ethertype is not used and the TPID of the inner TAG must be
0x8100 to be considered a double-tagged packet.
• GRE encapsulated IPv4 traffic: source MAC address and destination MAC address, IPv4
source and destination address, IPv4 protocol number. VLAN-ID, and TCP or UDP source
port and TCP or UDP destination port. Also, inner IPv4 source address and inner
destination IPv4 address are used if there is at least one GRE or IPv6 tunnel configured.
NOTE
TCP or UDP Destination and Source port is used under the following conditions:
– Packet is non-fragmented and without option, and packet is a TCP or UDP packet
– or, the load-balance force-l4-hashing command is configured.
• IPv6 tunnel encapsulated IPv6 traffic: source MAC address and destination MAC address,
IPv6 source and destination address, TCP or UDP source port and TCP or UDP destination
port, and IPv6 next header. and VLAN-ID.
NOTE
TCP or UDP Destination and Source port is used under the following conditions:
– Packet is a TCP or UDP packet
– or, the load-balance force-l4-hashing command is configured.
For 6over4 encapsulated packets, inner IPv6 destination address and inner IPv6 source
address are used if there is at least one GRE or IPv6 tunnel configured.
• Layer-2, non-IPv4.IPv6 or non-MPLS packets: source MAC address, destination MAC
address, VLAN ID, Ethertype and Inner VLAN ID (for double-tagged packets).
• For Layer 3-Routing, the hash index is based on the following:
• IPv4 or IPv6 traffic: source MAC address and destination MAC address, IPv4v6 source and
destination address, VLAN-ID, IPv4 protocol number or IPv6 next header and TCP or UDP
source port and TCP or UDP destination port.
NOTE
TCP or UDP Destination and Source port is used under the following conditions:
– Packet is non-fragmented and without option, and packet is a TCP or UDP packet
– or, the load-balance force-l4-hashing command is configured.
• GRE encapsulated IPv4 traffic: source MAC address and destination MAC address, IPv4
source and destination address, IPv4 protocol number. VLAN-ID, and TCP or UDP source
port and TCP or UDP destination port. Also, inner IPv4 source address and inner
destination IPv4 address are used if there is at least one GRE or IPv6 tunnel configured.
