Accessing Switch through Telnet

1. Direct Access through Console port
2. Access through LAN by Telnet
3. SSH (source socket shell)application

Step2. Access through Telnet

• To access the IOS of switch from LAN
• Privilege and virtual terminal password is must.

Then do the configuration as

• Switch>enable
• Switch# conf terminal
• Switch(configure)# interface vlan 1
• Switch(configure-if)# ip address 192.168.0.10 255.255.255.0
• Ä  Switch(configure-if)# no shut
• Switch(configure-if)#exit

Now go to the client computer and do as. Start—-run— give the CMD in run

• C:/> telnet 192.168.0.10 and press enter
• It prompt for vty password then
• Switch> enable
• Now it will prompt for console password give it and it will enter to privilege mode as
• Switch#
• Switch# configure terminal ( for configuration on switch by virtual terminal)

MAC Address Table:

For showing MAC address table as

•  Switch# Show mac-add-table

And to show the aging time of the mac-add-table as

• Switch# Show mac-add-table aging-time

Requirement for entering addresses statically to MAC address table

MAC address of the computer

• Port no of that computer is to be used
• Switch> enable
• Switch# configure terminal
• Switch(configure)# mac-add-table static 0052.45b5.2g52(mac address)  int fa 0/1(port no) vlan 1
• If we want that to take the mac address automatically we use the work “sticky” for mac address as
• Switch(configure)# mac-add-table static sticky int fa 0/1 vlan 1

If we want to remove it from table as

• Switch(configure)# no mac-add-table static 0052.45b5.2g52 int fa 0/1 vlan 1 and save it as
• Switch# write mem
