I used it myself when studying for my certifications,\n

Watch until the end of this video, we’ll\n

If you want to get your own copy of NetSim,\n

In this lab we will configure EtherChannel\n

All of the connections between these switches\n

However, because of spanning tree protocol\n

The inactive link will act as a backup, which\n

be forwarding at the same time, to increase\n

We will configure Layer 2 etherchannels between\n

layer switches, and then we will configure\n

And frst let’s check the spanning-tree situation.

So, G0/1, connec ted to DSW1, is the root\n

It won’t forward or receive any frames,\n

If we configure this connection with DSW1\n

two interfaces here, they will be replaced\n

be the new root port, and will forward traffic\n

CONF T. Let’s configure both interfaces\ntogether.

To configure etherchannel, use the channel-group\ncommand.

CHANNEL-GROUP 1 MODE, now which options do\nwe have?

Step 1 instructs us to use LACP, so we can\n

If we use passive mode, we have to ensure\n

But let’s just go with active on both sides.

Okay, we’re also instructed to configure it as\na trunk.

To do so, let’s configure the port-channel\n

Okay, so because DSW1’s port-channel isn’t\n

SHOW INTERFACES TRUNK, but let’s just check\n

So, you can see that the port-channel 1 interface\n

and G0/2, you can see that the SWITCHPORT\n

Let’s also check the status of the EtherChannel,\n

So, the port-channel interface itself is SD,\n

So, they are configured to be part of an etherchannel,\n

as stand-alone, individual ports.

It’s because we haven’t configured DSW1\nyet.

So, next up let’s configure DSW1’s side.

CONF T. The configuration will be the same\nas on ASW1.

Passive would work as well here, since ASW1’s\n

Now let’s configure the port-channel as\na trunk.

As you can see, this model of switch supports\n

we have to set the encapsulation first.

SWITCHPORT TRUNK ENCAPSULATION DOT1Q.

Okay, now the EtherChannel should be up.

The port-channel interface has the flags SU,\n

These are the flags we want to see.

For the member ports, the flag is P, meaning\n

This is also what we want to see.

Let’s check the trunk interfaces.

Okay, port-channel 1 properly became a trunk.

Before configuring the next EtherChannel,\n

of SHOW SPANNING-TREE is different.

As I said, we no longer see G0/1 and G0/2\n

F0/1 and 2 are designated because they are\n

Next up is the EtherChannel between ASW2 and\nDSW2.

The configurations will be almost identical\n

active mode we’ll use desirable, which is\nthe PAgP equivalent.

Remember, PAgP has desirable and auto modes,\n

So I’ll quickly run through the configurations,\nfirst on ASW2.

CONF T. INTERFACE RANGE G0/1 to 2.

CHANNEL-GROUP 1 MODE, now here is the only\ndifference.

So, the port-channel interface was created, now let’s\n

That’s ASW2’s side, next up DSW2.

CONF T. INTERFACE RANGE G1/0/3 to 4.

CHANNEL-GROUP 1 MODE DESIRABLE.

Next up, make the port-channel a trunk.

This is the same model of switch as DSW1,\n

SWITCHPORT TRUNK ENCAPSULATION DOT1Q.

DO SHOW ETHERCHANNEL SUMMARY.

Here are the flags we want to see, SU for\n

Next up let’s configure the Layer 3 port-channel\n

We’re already on DSW2, so let’s start\nhere.

So, first you should make these routed ports\n

Now when you make the channel-group, the port-channel\n

We already used channel-group 1 for the connections\n

I used ON, because the instructions say to\n

Now all we have to do is configure an IP address\n

IP ADDRESS 10.0.0.2 255.255.255.252.

IP ADDRESS 10.0.0.1 255.255.255.252.

Okay let’s take a look at the status.

Notice that the flags are now RU, meaning\n

once again display P, which is what we want\nto see.

Let’s try a ping to DSW2’s port-channel\ninterface.

Next up we are supposed to configure static\n

So, let’s check the current routing table.

There is no routing table, why is that?

Well, for a multilayer switch to build a routing\n

DSW1 was able to ping DSW2 because it’s\n

ip routing, even if we configure static routes,\n

So let’s enable IP routing and configure\nthe route here on DSW1.

So, these routes we already have for the VLAN1\n

Let’s configure a static route to SRV1’s\nsubnet.

IP ROUTE 172.16.2.0 255.255.255.0, and the\nnext hop is 10.0.0.2.

Okay, it was added to the table.

And I’ll configure a route to the PCs’\nsubnet.

IP ROUTE 172.16.1.0 255.255.255.0, and the\nnext hop is 10.0.0.1.

Okay, looks like we have all of the routes\nwe need.

So, let’s try a ping from PC1 to SRV1.

PC1’s default gateway is the SVI on DSW1,\n

3 port-channel to DSW2, which will forward\nit to SRV1.

So, I’ve said this a few times before, but\n

a few timeouts, this is because the ARP process\n

Okay next up we are asked to check the default\n

The access switches are the same model, and\n

model too, so I’ll just check ASW1 and DSW1.

ASW1 first. To check the load-balancing method,\n

DO SHOW ETHERCHANNEL LOAD-BALANCE.

So, the default is source MAC address.

All frames from the same source MAC address\n

While we’re on ASW1, I’ll do step 6 as\n

Okay, the show command uses ‘etherchannel’,\n

we use this command: PORT-CHANNEL LOAD-BALANCE\nSRC-DST-IP.

DO SHOW ETHERCHANNEL LOAD-BALANCE.

I’ll go on ASW2 and do the same now. EXIT.

PORT-CHANNEL LOAD-BALANCE SRC-DST-IP.

DO SHOW ETHERCHANNEL LOAD-BALANCE.

Finally let’s check the load-balancing method\non DSW1.

DO SHOW ETHERCHANNEL LOAD-BALANCE.

Okay, the default on this model is the same\n

PORT-CHANNEL LOAD-BALANCE SRC-DST-IP.

DO SHOW ETHERCHANNEL LOAD-BALANCE.

Now I’ll hop back on to DSW2 and do the\nsame configuration.

PORT-CHANNEL LOAD-BALANCE SRC-DST-IP.

DO SHOW ETHERHCHANNEL LOAD-BALANCE.

So, in today’s lab we configured Layer 2\n

We also configured the EtherChannel load-balancing\n

IP addresses to determine which interface\n

was the source MAC address only.

Next let’s take a look at a lab in Boson\nNetSim for CCNA.

Okay, for today's Boson NetSim lab preview,\n

There are 3 labs about EtherChannel in NetSim\nfor CCNA.

This one here, EtherChannel Negotiation Protocols:\n

Click on lab instructions, and this is the\ndiagram.

So, you can see there are many opportunities\n

All of these switches have redundant links\nconnecting them.

These are the commands you need to know.

You do know all of these commands already,\n

I'll show you that in a minute.

Task 1, plan EtherChannel configurations,\nwith 10 steps.

Task 2, review initial configurations, with\n12 steps.

And then task 3, verify configurations.

So, for this preview we'll just do task 1.

So, we won't actually do any configurations, we're\n

So, this task involves planning Layer 2 EtherChannel\n

You will be creating a port-channel between\n

Step 1, determine the number of links that\n

Okay so, looks like two links, 5 and 6.

Now, what are the actual interface IDs of\nthese interfaces?

So I will show you that SHOW CDP NEIGHBORS\ncommand here on DSW1.

So, CDP is Cisco Discovery Protocol.

It's a Cisco proprietary protocol that is\n

So, when I enter this command here on DSW1\n

of these switches it's connected to.

And notice under Local Interface it shows\nFastEthernet 5 and 6.

So, those are these two interfaces here.

And also here under Port ID, these are the\n

So, FastEthernet5 on DSW1 is connected to\nFastEthernet5 on DSW2.

FastEthernet6 on DSW1 is connected to FastEthernet6\non DSW2.

Verify the line and protocol states of each\ninterface.

This is referring to those two end columns\n

So, they are up and up, no problems.

Observe the trunk state of each port.

So, FastEthernet5 and 6 are both 'desirable'.

Looks like all VLANs are allowed.

Default...only VLAN 1 exists by default.

And, yeah, looks generally default except\n

Because it's desirable, it's using DTP, so\n

Let's check that out on DSW2 also.

Same, it is also using ISL for FastEthernet5\nand 6.

Okay, switchports configured to be a member\n

same way in order for the port-channel to\noperate correctly.

Verify that the interfaces are configured\ncorrectly.

Let's just check SHOW RUNNING-CONFIG.

Okay, there is no configuration on FastEthernet5\nand 6.

Same here, so that should be no problem.

Okay, step 5, what command can you issue to\n

That is this command, I'm not actually going\n

CHANNEL-GROUP 1 MODE, and then either active\n

PAgP, or on for static EtherChannel.

Okay, observe spanning-tree output for VLAN\n1.

Okay, let's do that first on DSW1.

I think only VLAN 1 exists, so we could just\n

Oh, so DSW1 looks like it is the root port\n(*bridge).

All interfaces have a designated role.

And it says that here, 'this bridge is the\nroot'.

Okay first, spanning-tree quiz.

Which of DSW2's ports will be the root port?

So, they both have the same root cost, 19,\n

The neighboring switch ID is the same, they're\n

So the last tie-breaker is the neighboring\n

So that is FastEthernet5 here.

So, I think DSW2's FastEthernet5 should be\nthe root port.

And I was correct, there we go.

In this lab, how much bandwidth is available\n

So, it's FastEthernet, so it should be 200\nmegabits per second.

SHOW INTERFACE F0/5, has here...that is 100,000\nkilobits.

And FastEthernet0/6 should be the same.

Okay, so when you combine those two together,\n

have a bandwidth of 200,000 kilobits, 200\n

Step 8, why is the full amount of bandwidth\n

Well, that's because FastEthernet6 is blocking\n

How does EtherChannel increase the amount\n

Because it combines them to form a single\nlogical interface.

I just showed you that in the lecture video.

So, number 10, how many switchports can be\n

So, up to 8 can be active at any one time,\n

but only up to 8 will be active and then the\n

ready to take over if one of the active ports\nfails.

Just take a quick look at task 2, what kind\nof things you do.

Determine the number of links that can be\n

Here we go, configure the interfaces as members\n

Verify that an active trunk link exists on\n

Verify the correct amount of bandwidth.

As I said, 200 megabits per second is available\n

And then finally, verify your EtherChannel\nconfiguration.

So, if you ever have any trouble you can check\n

As you can see it is quite lengthy and detailed,\n

It's another great study resource.

Even if you don't have any trouble, I recommend\n

Okay, and you can also grade the lab by clicking\nup here.

Now, I of course didn't finish the lab, so\n

But if you check the device configurations\n

If you put in some extra commands that you\n

And it grades the lab for you.

So, I think Boson NetSim for CCNA is a great\nstudy resource.

It's got a huge catalogue of in-depth labs\n
