The 802.1Q VLAN-ID tag (VID) in the user's traffic is transparent to the switches. This
allows all the CE switches to behave as if attached to a shared LAN.
Two types of ports are defined in the network switches deployed by the service provider:
•
User (customer) port – a port that is connected to a user. Packets that are transmitted
through this port have no added tag.
•
Uplink (core) port – a port that is connected to the service provider's network. All
packets that are transmitted through this port are either control packets or packets
with an additional tag.
Jumbo Frame
The Jumbo frame is an extension to current Ethernet Frame specifications for hardware and
frame format to support payloads greater than 1500 Bytes for Type interpretation and Length
interpretation frames. This is useful for Gigabit Ethernet technology, providing a means to
carry large MTU packets without fragmentation over a high-speed broadcast network.
Jumbo frames are used between end-stations that support larger frame sizes for more efficient
transfers of bulk data. Both end-stations involved in the transfer must be capable of
supporting jumbo frames.
The tls jumbo-frame command in Global Configuration mode enables more efficient packet
processing on workstations and servers by increasing the maximum packet size to 10K.
