LAB_2

Virtual Local Area Network (VLAN) Access Control Lists (ACL) (VACL or VLAN-ACL)

The CCNA taught ACLs standard, extended and named (standard and extended) the VACL is a standard or extended access list (no surprise) that is supported on Cisco IOS Software on Multilayer Switches (this is important) that can be mapped as the name suggests to a specific VLAN (take note).

This means that instead of an ACL filtering all traffic ingressing or egressing a particular port the ACL will filter all traffic ingressing and egressing a particular VLAN (cool huh).

The below config uses a named ACL in conjunction with the other particulars to make the VACL work. If you are rusty on the Access Lists the previous lab used an extended access list you can then also go on to try your hand at standard access lists on your own.

The aim of this lab is to block telnet, ftp, www and allow all other traffic to PC1 and PC2.

PC1 is in VLAN 10 with IP address 192.168.10.200 255.255.255.0 Default Gateway (DG) 192.168.10.1

PC2 is in VLAN 20 with IP Address 192.168.20.250 255.255.255.0 DG 192.168.10.50

The end result of this will be if you attempt to for example telnet from one of the ASW switches to the PCs (1 or 2) you should get the following:

ASW1#telnet 192.168.10.200 Trying 192.168.10.200 ... % Connection timed out; remote host not responding

Still trying to sort out LAB time so will test this out and update as needed.

Notes and Notices:

This is a part of my personal BCMSN notes and research to assist myself in learning and understanding the concepts and theory for the BCMSN exam. I learn by making notes reading and writing things down and wish to file them where I can’t lose them. These notes are not to be seen, judged or mistaken for replacements to Cisco recognized and authorized training which I personally support and attend and suggest you undertake if you are going for the BCMSN Certification.

QoS

The idea behind this config is to enable Quality of Service (QoS) create access-lists that apply to certain traffic/data (TFTP, FTP and icmp (echo) in this case), define a class, create a policy define precedence and apply those settings to downstream switches. If you remember from previous QoS posts the higher the precedence (voice) the more important and delay sensitive the lower the precedence (www) the less delay sensitive and easier it can handle dropped packets without end-user issues.

Spanning Tree Protocol
As a base config use the config of LAB 3 because this enables trunking between all the switches. The reason for this is because you want VLAN 1, 10, and 20 are going to be passed between ASW and DSW switches.

For reference look at this document it contains STP, PortFast and UplinkFast information and configuration information.

Im grafting so quantity over quality… I will go over this sometime this coming weekend for mistakes

Trunking

This lab builds directly onto the previous lab where the default VLAN was shut and a new VLAN was created (basically to give practice for creating a vlan). This lab will now create trunk links between switches to allow more than a single VLANs information to traverse a link. If you are wondering why I am explicitly declaring trunks instead of allowing DTP to do its thing read this, and this.

Distribution Switch 1

Step 1: Setup the basics all of the following is CCNA level stuff and should easy if not second nature. This is to get the security and host name down before going onto the interface configuration.

Enter Privileged Mode switch>enable Enter Global Configuration Mode switch#configure terminal Change the hostname of the switch switch(config)#hostname DSW1 Enable secret and password DSW1(config)#enable secret ciscosystems DSW1(config)#enable password cisco Setup a local user database DSW1(config)#username admin@mydomain.com privilege 15 password cisco Setup the console port password DSW1(config)#line con 0 DSW1(config-line)#login local DSW1(config-line)#exit Setup the Virtual Teletype Terminal (VTY) Password DSW1(config)#line vty 0 4 DSW1(config-line)#password cisco DSW1(config-line)#login DSW1(config-line)#exit Setup the Auxiliary Password DSW1(config)#line aux 0 DSW1(config-line)#no exec DSW1(config-line)#exit

Step 2: Setup the management interface

Setup the default VLAN ip address from remote ip admin if there was a GUI and to Telnet to the switch DSW1(config)#interface vlan 1 DSW1(config-if)#ip address 192.168.1.1 255.255.255.0 NB I am shutting the interface DSW1(config-if)#shut DSW1(config-if)#exit

Step 3: Assign an ip address to the new VLAN to ping

Setup VLAN 100 ip address from remote ip admin if there was a GUI and to Telnet to the switch DSW1(config)#interface vlan 100 DSW1(config-if)#ip address 192.168.100.1 255.255.255.0 DSW1(config-if)#no shut DSW1(config-if)#exit

Step 4: Setup other interfaces

Setup Fastethernet Interfaces DSW1(config)#interface fastethernet 0/1 DSW1(config-if)#description DSW1 - ASW1 DSW1(config-if)#exit DSW1(config)#interface fastethernet 0/2 DSW1(config-if)#description DSW1 - ASW1 DSW1(config-if)#exit DSW1(config)#interface fastethernet 0/3 DSW1(config-if)#description DSW1 - ASW2 DSW1(config-if)#exit DSW1(config)#interface fastethernet 0/4 DSW1(config-if)#description DSW1 - ASW2 DSW1(config-if)#exit Create and Associate VLAN 100 with Fe 1 to 4 DSW1(config)#interface range fastethernet 0/1 - 4 DSW1(config-if-range)#speed 100 DSW1(config-if-range)#duplex auto DSW1(config-if-range)#switchport DSW1(config-if-range)#switchport trunk encapsulation dot1q DSW1(config-if-range)#switchport trunk native vlan 1 DSW1(config-if-range)#switchport trunk allowed vlan 1,100 DSW1(config-if-range)#switchport mode trunk DSW1(config-if-range)#exit DSW1(config)#interface fastethernet 0/11 DSW1(config-if)#description DSW1 - DSW2 DSW1(config-if)#exit DSW1(config)#interface fastethernet 0/12 DSW1(config-if)#description DSW1 - DSW2 DSW1(config-if)#exit Associate VLAN 100 with Fe 11 and 12 DSW1(config)#interface range fastethernet 0/11 - 12 DSW1(config-if-range)#speed 100 DSW1(config-if-range)#duplex auto DSW1(config-if-range)#switchport DSW1(config-if-range)#switchport trunk encapsulation dot1q DSW1(config-if-range)#switchport trunk native vlan 1 DSW1(config-if-range)#switchport trunk allowed vlan 1,100 DSW1(config-if-range)#switchport mode trunk DSW1(config-if-range)#exit

Step 5: Shut down non-used interfaces

Administratively shut down all ports not connected DSW1(config)#interface range fastethernet 0/5 - 10 DSW1(config-if-range)#shut DSW1(config-if-range)#exit Exit Global Configuration Mode DSW1(config)#exit

Step 6: Check your work

Check that you named the interfaces correctly, havent missed out on a connected interface and that the duplex and speed setting are correct DSW1#show interfaces status show the vlans that are configured DSW1#show vlan show switchport you can change the fastethernet 0/4 for any active port for information DSW1#show interface fasthethernet 0/4 switchport show which interfaces are trunking DSW1#show interfaces trunk show run the running configuration DSW1#show run

Step 7: Save your work

The way of the VLAN

Looking back over the previous config done on the switches you will remember that all switches were part of VLAN 1 (default vlan). If you don’t know this or know where I pulled this information from issue this command:

ASW1#show interfaces status

The output will show interface, the description of the interface, status, VLAN, duplex, speed and the type of connection (all connections by default unless told otherwise belong to the default VLAN iow VLAN 1)

To practice VLANs I am going to change some information from the initial config and add VLANs.

I am a glutton for punishment, I retype and redo all configurations when I am practising for an exam from scratch (I don’t run from saved, I redo). Try it, it’s a pain in the backside and takes longer but it means that you are forced to type the commands one at a time from memory (don’t take a shortcut and use notepad either, type each command, move between interfaces, keep track which interfaces you have completed and which you still have to do). It pays off at the end of the day and helps you logically organize how you configure IRL (In Real Life).

This lab is pretty much exactly the same as the previous lab except for the small changes to VLAN 1 and the addition of VLAN 100. Other noteworthy changes would be the use of switchport access commands.

The object would be to be able to ping the various VLAN 100 interface ip addresses. There may be certain restrictions to what you can ping but as long as directly connected switches can ping the VLAN 100 interfaces you have VLAN 100 up and running.

Post Scriptum

I am going to assume* that if one telnets into a switch/router using the vlan 1 then go onto shut vlan 1 the session will be dropped (it will make sense if that were to happen). So I am going to assume you would have to use the Console connection to do this.

One can automate to an extent the speed and duplex commands with the interface range command for this lab, I just need to get into the habit of adding a description to my interfaces (don’t do that because I know what the interface are and do when setting it up, troubleshooting 6 months later I have found it to be another matter).

Also you can use the following to shorten what you have to type every time :-
ASW2(config)#define interface range OnetoFour fe 0/1, fe 0/2, fe 0/3, fe 0/4 ASW2(config)#interface range macro OnetoFour

*The say assumption is the mother of all f-ups. Until I have arranged lab time I am going to go on my assumptions because I want to test and see if this is the case.

The Topology

The above topology shows (from the top) a Distribution and Access switched network design with redundant links between Distribution switches and Distribution and Access Layers. Finally there are two attached end-devices (workstations).

The network is going to use the 192.168.1.0 network using the /24 (255.255.255.0) subnet thus allowing for 254 hosts on the network.

Lets say that the DSW switches are MLS switches for argument sake (I know the diagram doesn’t show it).

If you look at the colour key at the bottom you will find that each link colour combination represents a fastethernet port in this case. It’s a fairly simple Lab so its easy to have each link connected on Access Switch fe0/1 and then Distribution Switch fe0/1 on the other end.

I didn’t want to make much work for myself connecting things weird but you can do that by all means. All that means is that you really have to pay attention when you configure when Access Switch fe0/1 connects to Distribution Switch fe0/8 or something weird on one switch and then Access Switch fe0/5 connects to Distribution Switch fe0/12 on the other.

There is however still a catch to this lab layout, notice that from DSW1 to DWS2 the connections flip and the same applies to the ASW1 and ASW2 (meaning DSW1 fe0/1 connects to ASW1 while DSW2 fe0/1 connects to ASW2). Something that means I have to stay awake but not on my toes.

Initial Configuration

The initial configuration entails some things old (CCNA) and some one new command (not drastically new). I am going to go through what I am doing to practice for the exam and annotate the commands and generally what they do.

I am a weird Muppet, I want to know what and more importantly why something has to be used (probably the reason it takes me so long to study things). I can’t make sense of something unless I know command X is used to enable/do Y and relates to the theory in such and such a fashion for a particular reason.

Cisco CDP

In a LAB or Real World (RW) situation you would telnet or console into Distribution Switch 1 (DSW1) and work from there. First off I am going to use CDP to discover the network topology. This is old work from the CCNA and useful if you (1) don’t know the network topology, (2) remote into a network to do work and need to hop from one device to another and need network information, (3) have a huge network and never bothered to document growth (ISPs), or (4) you are too lazy or there is a foot thick metal vault door between you and the kit and changing the console cable from one switch/router to another one isn’t going to happen.

The following command gives a basic table of information,
DSW1#show cdp neighbors
To get specific information use,
DSW1#show cdp neighbors detail
With that information you can then do something like this:
DSW1#telnet 192.168.1.50 Trying 192.168.1.50 ... Open User Access Verification Password:_ DSW2#

Terminology:

Two terms that I have been made aware of recently that I need to remember out-of-band management and in-band management.

Out-of-Band Management is the use of a dedicated channel for device maintenance. Example of this would be using the Console port (Serial) or maybe the Auxiliary port (modem – pots – offsite) for management purposes.

In-Band Management is the use of regular channels for device maintenance. Example of this would be using Ethernet for Console Access (when you change the IP Address the session ends).

CDP

Cisco Discovery Protocol (CDP) is a useful and great protocol when you are sitting on the other side of the office/country/planet and don’t know what you are working with on a network but CDP has some holes for attackers to leverage that can cause problems.

CDP uses clear-text and unauthenticated to send information about network topology between network devices. An attacker can use a packet sniffer to get information about network infrastructure that we don’t really want them to have.

CDP isn’t needed on ports that no network management is done (this isn’t the case for Cisco IP Phones). You can also go ballistic and disable CDP totally thats up to you. To disable CDP use the following commands

CDP per-port

switch(config)#configure terminal switch(configp)#interface gigabitethernet 0/1 switch(config-if)#no cdp enable

CDP Globally

switch(config)#configure terminal switch(config)#no cdp run

Be careful with this, CDP is used in conjunction with or as support for other Cisco protocols

Telnet

Telnet has a few problems:

All usernames, passwords, and data sent over a public network (read: Internet) is sent in clear text and is thus vulnerable.
A user with an account on the system can gain elevated privelages.
A remote attacker could crash the Telnet service, preventing legitimate service rendering.
A remote attacker could find an enabled guest account that may be present anywhere in the trusted domain of the server.

iow Dont Telnet over the internet

SSH

SSH is a client and server protocol used to log in to another computer over a network. It provides strong authentication and secure communication over a public communication network. SSH may be “more” secure many vendors implementations of SSH is vulnerable.

switch(config)#configure terminal switch(config)#line vty 0-15 switch(config-line)#transport input ssh

VTY Access Control Lists (ACL)

One can associate ACLs to permit or deny access to a vty port to a switch.

The Number of VTYs differ make sure you get it right and configure an ACL on ALL the VTY connections and don’t leave one open

switch(config)#configure terminal switch(config)#access-list 12 permit 192.168.0.0 0.0.255.255 switch(config)#line vty 0 15 switch(config-line)#access-class 12 in

Inter-VLAN Routing (Router on a Stick)

Published

on April 22, 2008

in BCMSN, Certification, Cisco Systems and Inter-Vlan Routing

. 0 Comments

When a switch supports multiple VLANs but has no Layer-3 capability, the switch must be connected to an external Layer-3 device (router). This is done by creating a trunk link (isl or 802.1q) between the switch and router that can carry all VLAN information and provide inter-VLAN routing (a.k.a. Routing on a stick). The interface must be FastEthernet or better preferably.

There are some advantages and disadvantages to Inter-VLAN routing:

Advantages are that it is simple to implement, A Layer-3 switch (expensive) is not required, The router provides communication between VLANs.
Disadvantages are that the router is the single point of failure for the network, the single trunk link may become congested, Latency may be introduced as frames leave the switch.

Configuration

There are a couple of things that are needed to configure inter-VLAN routing. First things first would be that you need VLANs to route. I jumped the gun here and explained the entire process of Inter-VLAN routing; what can I say I was excited

So to in revision lets create some VLANs

switch>enable switch#config term switch(config)#vlan 100 name Inter switch(config)#vlan 200 name VLAN switch(config)#vlan 300 name Routing

Now lets configure an interface as a trunk on the switch

switch(config)#interface gigabitethernet 0/1-28 switch(config)#switchport trunk encapsulation dot1q switch(config)#switchport mode trunk

The switch now has VLANs and a Trunk Link onto the router

router>enable switch#config term switch(config)#interface fastethernet 0 switch(config)#no ip address switch(config)#description trunk-link switch(config)#interface fastethernet 0/0.1 switch(config)#description Native-vlan switch(config)#ip address 192.168.1.1 255.255.255.0 switch(config)#encapsulation dot1q native switch(config)#interface fastethernet 0/0.100 switch(config)#description Inter-vlan switch(config)#ip address 192.168.2.1 255.255.255.0 switch(config)#encapsulation dot1q 100 switch(config)#interface fastethernet 0/0.200 switch(config)#description VLAN-vlan switch(config)#ip address 192.168.2.1 255.255.255.0 switch(config)#encapsulation dot1q 200 switch(config)#interface fastethernet 0/0.300 switch(config)#description Routing-vlan switch(config)#ip address 192.168.3.1 255.255.255.0 switch(config)#encapsulation dot1q 300
To check the configuration use the following commands
router#show vlan 100
router#show ip protocols
router#show ip route
To verify and test connectivity do the following two things: First you ping from the router a host in each VLAN to confirm connectivty from the router to the separate hosts and VLANs.
router#ping instert.host.address.here Sending 5, 100-byte ICMP Echos to insert.host.address.here, timout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms
Second go to hosts (in our case 3 hosts one in VLAN 100, 200, 300) and ping other hosts in other VLANs (make sure the hosts you are pinging to are in other VLANs otherwise you aren’t testing Inter-VLAN connectivity). So a host on VLAN 100 will ping hosts in 200 and 300, a host in VLAN 200 will ping hosts in 100 and 300 and VLAN 300 will ping hosts in 100 and 200….
C:\Users\Administrator>ping insert.host.address.here Pinging insert.host.address.here with 32 bytes of data: Reply from insert.host.address.here: bytes=32 time<1ms TTL=127 Reply from insert.host.address.here: bytes=32 time<9ms TTL=127 Reply from insert.host.address.here: bytes=32 time<8ms TTL=127 Reply from insert.host.address.here: bytes=32 time<1ms TTL=127 Ping Statistics for insert.host.address.here: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 9ms, Average = 4ms C:\Users\Administrator>
