Question 2

Answer 2

start with access-list

#access-list    then give it a name
#access-list Flor01  then a permit or deny permission
#access-list Flor01 permit  then define protocol type.
#access-list Flor01 permit tcp  then a source IP address.
#access-list Flor01 permit tcp 10.10.1.0 then the mask.
#access-list Flor01 permit tcp 10.10.1.0 255.255.255.0   then add destination
#access-list Flor01 permit tcp 10.10.1.0 255.255.255.0   any eq www   (any www. * address)   This is an outbound rule.

Question 3

What have you done with Routers?

Answer 3

In the real world I’ve tweaked existing config to meet the needs of standing up a new client network. This included installation and cabling.

Question 4

What have you done with Switches?

Answer 4

Primarily checked to make sure ports were up or down. privileged mode key #show interfaces status. and changing their status or attributes of ports:

switch# config t ///To enter global configuration.

switch(config)# interface 01 no shutdown to bring it up or shutdown to bring it down.

I’ve used Traceroute to see where the route stopped in troubleshooting. ex. trace ip www.google.com

Configure the ip address first you have to enter from global configuration mode to interface vlan 1.

Switch#

Switch#conf t

Switch(config)#int vlan 1

Switch(config-if)#ip address {your ip address} {mask}

Switch(config-if)#no shutdown

Configuration of default gateway takes place in the configuration mode and the command does not include the mask for the ip.

Switch#

Switch#conf t

Switch(config)#ip default-gateway {ip address}

and set passwords.

Switch#

Switch#conf t

Switch(config)#line vty 0 15

Switch(config-line)#password {your password}

Switch(config-line)#login

Switch(config-line)#exit

Switch(config)#enable secret {your enable password}

Switch(config)#end

Switch#write
