What is IPv6 EtherType?
EtherType is a two-octet field in an Ethernet frame. The same field is also used to indicate the size of some Ethernet frames. EtherType is also used as the basis of 802.1Q VLAN tagging, encapsulating packets from VLANs for transmission multiplexed with other VLAN traffic over an Ethernet trunk.
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 the EtherType for an encapsulated IPv6 packet?
IPv6 Ethernet encapsulation (RFC 2464) IPv6 packets are encapsulated in Ethernet packets just like IPv4 packets, but with a new Ethertype (86DD rather than 0800).
What is Cvlan and Svlan?
CVLAN tag—Identifies the VLAN to which the frame belongs when it is transmitted in the customer network. SVLAN tag—Identifies the VLAN to which the QinQ frame belongs when it is transmitted in the service provider network. The service provider allocates the SVLAN tag to the customer.
What is the difference between QinQ and Dot1q?
VLAN packets are classified into dot1q packets, which carry only one VLAN tag, and QinQ packets, which carry two VLAN tags. Dot1q termination: terminates packets that carry one VLAN tag. QinQ termination: terminates packets that carry two VLAN tags.
What is EtherType 0x0800?
If the EtherType = 0x0800, the higher-layer protocol is IPv4. The first byte of the IPv4 header (byte 0) contains two items of information: The first nibble is the version number; this value is 0x4 to indicate IPv4.
What is the difference between QinQ and dot1q?
Why does my IPv6 say no Internet access?
Restart the router and modem. A problem with either your internet service provider or router might result in a lack of connection to an IPv6 address. If you have two network devices, restart the modem first, then wait a minute or two and restart the router. Check for network device driver updates (Windows).
What is the difference between Cvlan and Svlan?
What is QinQ tunneling?
802.1Q tunneling (aka Q-in-Q) is a technique often used by Metro Ethernet providers as a layer 2 VPN for customers. By using a different VLAN tag for each customer we can separate the traffic from different customers and also transparently transfer it throughout the service provider network.
How is EtherType used in 802.1Q VLAN tagging?
802.1Q VLAN tagging uses an 0x8100 EtherType value. The payload following includes a 16-bit tag control identifier (TCI) followed by an Ethernet frame beginning with a second (original) EtherType field for consumption by end stations. IEEE 802.1ad extends this tagging with further nested EtherType and TCI pairs.
What are the problems with the Vortec 8100?
Well, there are quite a few things holding the Vortec 8100 back from ever becoming popular: Iron block and heads, total engine weight is over 750 lbs. Older big block parts don’t fit on the Vortec 8100. Chevy LS parts don’t fit on the Vortec 8100. Limited production makes them harder to find than an LS.
Can a Chevy LS fit on a Vortec 8100?
Chevy LS parts don’t fit on the Vortec 8100. Limited production makes them harder to find than an LS. Like I mentioned above, the Vortec 8100 was used in GM pickup trucks as a diesel alternative. But, it was also used in a few other applications: As you can see, the Vortec 8100 was used in a host of different vehicles.
What’s the difference between a Vortec 8100 and a 454ci?
It was designed as a diesel alternative in the GM pickup truck line-up. The Vortec 8100 borrowed much of its design from the 454ci big block we all know and love. The main difference between the 8100 and big blocks of old is the increased stroke.
