Layer-3 Switch for Cisco switches
Although single-arm routing solves the communication problem between different VLANs, it also has its fatal defects:
-The single arm itself is the Backbone link of the network, which is easy to form a network bottleneck.
-The sub-interface relies on physical interfaces, and the application is not flexible
-You need to view the route table for each vlan forwarding, wasting device resources.
The problem above is caused by poor Routing Switching capabilities. To s

8 LS, DIR, MLS, Mdir, MKDIR, RMDIR
LS is a bit like the LS (LIST) command under UNIX:
Dir is equivalent to Ls-l (List-long);
MLS simply saves a file in a remote directory at the local side of a file;
Mdir equivalent to MLS;
MkDir is the same as MD (creating a subdirectory) under DOS:
RmDir is like an RD (delete subdi
