Labs: All Configuration and
Show , Debug commands
Ping
IP
Secondary IP - not possible on PT, need GNS3
Interface description
Interface speed, duplex
Enable secret,password -indepth
Banner
Telnet,Console,Aux
Copy command TFTP etc ,backup restore config
CDP
SSH
DHCP
NTP
Static Route
Floating Static Route
Default route
Switch Basic configuration and Management IP and default Gateway
Assigning VLAN 1 or native vlan or any VLAN IP via DHCP and Manually
VLAN
Allowed VLANS all options
Changing Native VLAN of a Trunk Port
IP Default gateway (without which cannot remotely ping or telnet)
Shutdown unsued ports and Port range command
Port modes
Trunk port multi VLAN and changing Trunk encapsulation to dot1q to allow Trunk
InterVLAN Basic Switch and L3 Switch
switchport security and violation modes
Err disable recovery
(When a violation is detected, the switch automatically places the port in the
"err-disabled" shutdown state.
By default, manual intervention by an administrator is necessary
to restore the interface to working order; this can be done by issuing
shutdown followed by no shutdown on the interface. )
OSPF Basic configuration
OSPF Cost, Priority,hello-interval,dead-interval
OSPF cost : command on interface = ip ospf cost , route (interface ) with lowest cost is preffered
in lab a iterfaces cost is increased so that another route/interface/router is choosen
OSPF default information originate
OSPF Passive interface ,passive interface default
Wild card masking
L3 Switch all above configurations.
Standard ACL
Extended ACL
Named ACL
InterVLAN ACL applied to subinterfaces.
Incoming versus Outgoing ACL
Port range used with ACL
DNS Block UDP for PC's as TCP is server and will not work , UDP works.
ICMP ACL incoming other end echo-reply block
Wild card masking
Named ACL incoming from left side http
Log
Log option
Static NAT
Dynamic NAT
PAT
IPv6 Interface address assignment types , IPv6 enable to interface and IPv6 autoconfif config mode
Manual assignment of all types of addresses and ping , different subnets and /
Note Ping possible even to local Router after a unique local or global IP is asigned.
Only link local ping not possible.
IPv6 Static route using Unique local and Global IP
IPv6 Stateless autoconfiguration FF FE and 7th bit
IPv6 DHCP
IPv6 OSPFv3
IPv6 Subnets
Ping, Extended Ping , Traceroute, SSH,Telnet
Troubleshoot and resolve Layer 1 problems
Framing ,CRC , Runts , Giants , Dropped Packets
Late Collisions , Input/Output errors
