TSHOOT 300-135 Ticket 7 on Port security
Hi ! everyone on today we are going to learn about Port security in this lab session which is given below in this topology.
Client 1 is unable to ping Client 2 as well as DSW1. The command ‘sh interfaces fa1/0/1′ will show following message in the first line
‘FastEthernet1/0/1 is down, line protocol is down (err-disabled)’
‘FastEthernet1/0/1 is down, line protocol is down (err-disabled)’
On ASW1 port-security mac 0000.0000.0001, interface in err-disable state
Configuration of ASW1
interface fa1/0/1
switchport access vlan 10
switchport mode access
switchport port-security
switchport port-security mac-address 0000.0000.0001
interface fa1/0/1
switchport access vlan 10
switchport mode access
switchport port-security
switchport port-security mac-address 0000.0000.0001
Answer: on ASW1 delete port-security & do on interfaces shutdown, no shutdown
Ans 1: ASW1
Ans 2: Port security
Ans 3: In Configuration mode, using the interface range Fa1/0/1 – 2, then no switchport port-security, followed by shutdown, no shutdown interface configuration commands.
Ans 2: Port security
Ans 3: In Configuration mode, using the interface range Fa1/0/1 – 2, then no switchport port-security, followed by shutdown, no shutdown interface configuration commands.
Through this lab session we have learned about the port security as we explained above in simple term and on our next session we will see on topic switchport trunk.
