Configuration of Telnet

Switch >

Switch > enable / / enter privileged mode

Switch#config / / enter global configuration mode

Switch (config) # interface vlan 1 / / enters the interface configuration mode. VLAN1 represents the port of the entire switch. Layer 3 switches can specify multiple VLAN IP, and all of them can use Telnet.

Switch (config-if-vlan 1) # ip address 10.1.1.1 255.255.255.0 / / configure the IP address of VLAN1

Switch (config-if-vlan 1) # no shutdown / / activate VLAN1

Switch (config-fi-vlan 1) # exit

Switch (config) # telnet-server enable / / enable Telnet service

Switch (config) # username admin privilege 15 password 0 admin / / create a user name and password. 15 represents the weight, 0 indicates the password is in clear text

Switch (config) # authentication line vty login local / / Authentication for local users

2 port configuration

(1) configure port rate and duplex mode

Switch#config

Switch (config) # interfaceEthernet 1-0-1

Switch (config-if-ethernet1/0/1) # speed-duplex auto / / Port rate is autonegotiation (default option)

Force10-full / / 10 megabit full duplex

Force10-half / / 10m half duplex

Force100-full / / 100m full duplex

Force100-fx / / 100m optical duplex

Force100-half / / 100m half duplex

Force10g-full / / 10G full duplex

Force1g-full / / 1000 megabit duplex

Force1g-half / / 1000 half duplex

Switch (config-if-ethernet1/0/1) # exit

(2) set the broadband occupied by the port to receive and send data.

Switch (config) # interface ethernet1/0/2

Switch (config-if-ethernet1/0/2) # bandwidthcontrol 10000 both / / sending and receiving data bandwidth 10m

1000 receive / / received data bandwidth 1m

1000 transmit / / transmit data bandwidth 1m

KB is the unit

(3) Port image

Switch (config) # monitor session1 sourec interface ethent 1-0-1-10 both / / Mirror the data sent and received on ports 1-10 of Mirror Group 1

Switch (config) monitor session1 destination internet 1-0-24 / / mirrors the received and transmitted data of mirror group 1 to port 24

(4) Port loop detection

Switch (config) # loopback-detectioninterval-time 30 15 / / configure the sending interval of single-port loop detection messages, once every 30 seconds when there is a loop, and once every 15 when there is no loop.

Switch (config) # interface Ethernet 1-0-1-24

Switch (config-if-port-range) # loopback-detection special-vlan 1 / / Port Loop Detection is enabled on the entire switch

Switch (config-if-port-range) # loopback-detectioncontrol shutdown / / shut down the port if it is found to have a loop

Switch (config-if-port-range) # exit

Switch (config) # loopback-detectioncontrol-recovery time 360 / / configure the default time for port loop detection

(5) Port aggregation

Switch (config) # port-group 1 / / create port group 1. The port group number cannot be the same as that of other switch groups.

Switch (config) # interface Ethernet 1-0-1-2

Switch (config-if-port-range) # port-group1 mode no / / adds ports 1-2 to the 1 port group, the mode is manual.

Mode passive / / active mode

Mode active / / passive mode

Note: if the first switch port is configured in manual mode, the port on the other switch should also be in manual mode. If one switch is active, the other is passive.
