Ethernet Specifications

Framing & Ethertypes

  • The UNY-IX infrastructure offers ports that implement the Ethernet standard (IEEE 802.3-2012 / Ethernet II).
  • Port in Access/Tangged mode, which means that only untagged Ethernet Frames are allowed. 802.1q-tagged frames not allowed.
  • Allowed ethertypes are: IPv4 (0x0800), IPv6 (0x06dd), ARP (0x0806) and 802.3ad – LACP (0x8809). Traffic with any other ethertype may be dropped

Maximum Transmission Unit (MTU)

UNY-IX allowed L2 payload (L3 MTU) Maximum for 1500 bytes. Frames exceeding this payload may be dropped without further notice.

Link aggregation allows you to combine multiple Ethernet links into a single logical link between two networked devices. Link aggregation is sometimes called by other names:

  • Ethernet bonding
  • Ethernet teaming
  • Link bonding
  • Link bundling
  • Link teaming
  • Network interface controller (NIC) bonding
  • NIC teaming
  • Port aggregation
  • Port channeling
  • Port trunking

The most common device combinations involve connecting a switch to another switch, a server, a network attached storage (NAS) device, or a multi-port access point.

Network devices and management functions treat the link aggregation group (LAG) of multiple Ethernet connections as a single link. For example, you can include a LAG in a virtual local area network (VLAN). You can also configure more than one LAG on the same switch, or add more than two Ethernet links to the same LAG (the maximum number of links per LAG depends on your device).

Some network devices support Link Aggregation Control Protocol (LACP), which helps to prevent errors in the link aggregation setup process.
