What is the difference for global vlan mapping on different Switch?

13

The global VLAN Mapping means that configure Vlan Mapping in vlan view.
Only S2700EI、S3700EI and S3700SI can support globlal VLAN Mapping,others can not support.
All the S2700EI Switch can not support global Vlan Mapping and interface Vlan Mapping at the same time except S2750EI. S3700EI and S3700SI can support them at the same time.

What are the differences between network bridges and VLANs
Network bridges can implement packet forwarding at Layer 2 on the wide area network (WAN) side. Only Layer 2 interfaces can be added to virtual local area networks (VLANs). Only Layer 3 interfaces can be added to network bridges.

Add an interface to different VLANs
An access interface cannot be added to different VLANs. Run the port default vlan command to configure a default VLAN. A trunk interface can be added to multiple VLANs by running the port trunk allow-pass vlan command. A hybrid interface can be added to multiple VLANs in untagged or tagged mode by running the port hybrid untagged vlan or port hybrid tagged vlan command.

What is the difference between NAT server and static NAT
The difference between the NAT server and static NAT is as follows: The NAT server changes only the address but not the port number when an internal device accesses the external network. The device enabled with static NAT changes the IP address and port number when an internal device accesses the external network.

Differences between bit transparent mapping and MAC transparent mapping
Bit transparent mapping (11.1G): 10GE LAN client-side signals are mapped into OTU2e signals by increasing the OTU frame frequency. This mapping method guarantees a desired FEC coding gain and correction capability. However, this method generates a line rate of 11.1 Gbit/s, which is higher than the standard rate of OTU2 signals. MAC transparent mapping (10.7G): 10GE LAN client-side signals are encapsulated using the GFP-F method and are mapped into OTU2 signals using 10GE MAC frames. This mapping method guarantees a desired FEC coding gain and correction capability and generates a line rate of 10.71 Gbit/s. Bit transparent mapping (10.7G): 10GE LAN client-side signals are mapped into OTU2e signals by occupying some FEC areas of standard OTU frames. This method makes some FEC areas be occupied to transmit signals, which weakens the FEC/AFEC coding gain and error correction capability. As a result, the rate of line-side signals is 10.71 Gbit/s.
