What is 0x8100 EtherType?
0x8100 is standard ethertype for single tagged frames (802.1Q), it can be used(and it is) for QinQ tunneling but you should be careful with other vendors configuration, as defaults vary.
What is the EtherType for an encapsulated IPv6 packet?
86DD
IPv6 packets are encapsulated in Ethernet packets just like IPv4 packets, but with a new Ethertype (86DD rather than 0800).
How many Ethertypes are there?
Ethertypes
Ethertype (decimal) | Ethertype (hex) | Description |
---|---|---|
2048 | 0800 | Internet Protocol version 4 (IPv4) |
2049 | 0801 | X.75 Internet |
2050 | 0802 | NBS Internet |
2051 | 0803 | ECMA Internet |
What is the purpose of EtherType?
The purpose for the Ethertype is to provide an identifier whereby the communications software can differentiate between various types of protocols. A different protocol handler is used for different function, and the Ethertype identifies the frame as belonging to one or another protocol family.
What is Dot1q tunneling EtherType?
802.1Q tunneling enables service providers to use a single VLAN to support customers who have multiple VLANs, while preserving customer VLAN IDs and keeping traffic in different customer VLANs segregated. A port configured to support 802.1Q tunneling is called a tunnel port.
What is EtherType value?
EtherType is a two-octet field in an Ethernet frame. It is used to indicate which protocol is encapsulated in the payload of the frame and is used at the receiving end by the data link layer to determine how the payload is processed. EtherType values are assigned by the IEEE Registration Authority.
What is the EtherType in the Ethernet frame of the ARP request?
ARP protocol parameter values have been standardized and are maintained by the Internet Assigned Numbers Authority (IANA). The EtherType for ARP is 0x0806. This appears in the Ethernet frame header when the payload is an ARP packet and is not to be confused with PTYPE, which appears within this encapsulated ARP packet.
What does 0x0800 mean?
0x0800 in the protocol type field indicates this is an IPv4 packet and the hardware type showing 0x0001 indicates this is an ethernet packet. This the expected output for ARP, you should also see the request initially go out to all hosts (to MAC address ffff.
Do you need EtherType 0x88a8 for Cisco 7600 Router?
For Cisco 7600 router to operate seamlessly with other vendors it is required to provide a mechanism to change the default ethertype. Moreover, there is a need to support ethertype 0x88A8 to support provider bridge defined by IEEE 802.1ad.
Is there a physical port for EtherType 0x88a8?
Under the custom ethertype model, ethertype 0x9100, 0x9200 and 0x88A8 can be configured using “dot1q tunneling” CLI under a physical port. The explanation for the error message: [chars].
What is the ether type for IEEE 802.1ad / 0x88a8?
Re: IEEE 802.1ad / 0x88a8. Currently, the default ether type is 0x8100 on a Cisco 7600 for the Q-in-Q outer tag. However, a few non-Cisco vendors use 0x9100 or 0x9200 ether type for the Q-in-Q outer tag.
What kind of protocol is 0x88ca TIPC for?
0x88CA TIPC, Transparent Inter Process Communication Protocol. 0x88BB LWAPP, Light Weight Access Point Protocol. 0x88CC LLDP, Link Layer Discovery Protocol. 0x88DC WSMP, WAVE Short Message Protocol. 0xFFFF reserved.
