speed rate, duplex mode, flow control switch state, broadcast storm suppression of the
port and the statistic state of the data packets will be displayed. The information of all ports
on the switch will be shown if no port is specified.
Using [detail] to show the detail information for ethernet port and port-channel port,
the information is related with the type of switch, board card.
For ethernet port, using status to show important information of all the layer 2 ports by list
format. each port is a row, the showing information include port number, Link, Protocl
status, Speed, Duplex, Vlan, port type and port name; counter packets show package
number statistics of all ethernet ports, include layer 2 unicast, broadcast, multicast, error
of input and output redirection package number; counter rate show the rate statistics of all
ethernet ports, input and output package number, byte number in 5 minutes and 5
seconds.
Example: Show the information of VLAN 1
Switch#show interface vlan 1
Vlan1 is up, line protocol is up, dev index is 2005
Device flag 0x1003(UP BROADCAST MULTICAST)
