help me please

BAYOUMISOFT

i'm training with boson simulation and i got problem with it

i always go to ethernet interface and put ip and do no shut but when

i do show interface br

i found the both status and protocol is down, i don't know why??!!!,



and next pic appears after i do sh run

QUIX0TIC

Are these interfaces connected to anything?

johnnynodough

That would be my guess, its not administratively down and has an IP. Connect the ethernet to a switch in the network designer.

Mr.Noe

what about the no shutdown command, would that bring up the interfaces in his situtation?

johnnynodough

Its just down, not administratively down, admin down is when you need the shutdown command, or when you see it shutdown in the running config. Its just not connected to anything.

once you do a no shutdown, that command should appear under the respective interface in the runing configuration --which is not in your case.

If the interface were not connected to anything, the status would be up and the protocol would be down. When both status and protocol are down, that means you haven't run the no shutdown command on that interface in your current configuration.

I hear BOSON sims are squeaky..... are you sure you're executing the no shutdown command from the right interface, because in your example, serial1 looks like you ran a no shut on it but it doesn't have a carrier.

Post the commands you entered from your router prompt. Just copy it and past it here instead of linking an image.

Exactly the opposite. If it is shutdown, then shutdown will appear in the running config, no shut down wont appear after a no shutdown command.

If you dont have anything connected it will be down and down, if there is no hardware connection how could the hardware be up?

You're right about the no shutdown command. I just double checked. My bad.

But the interface thing... here's an example from my router. Look at the Ethernet0 interface:

This is when the interface is running:

LAB_B#sh ip int brief
Interface                  IP-Address      OK? Method Status                Prot
ocol
BRI0                       unassigned      YES NVRAM  administratively down down

BRI0:1                     unassigned      YES unset  administratively down down

BRI0:2                     unassigned      YES unset  administratively down down

Ethernet0                  192.168.10.33   YES NVRAM  up                    up
Loopback0                  192.168.0.3     YES NVRAM  up                    up

Serial0                    192.168.10.58   YES NVRAM  down                  down

Serial1                    10.1.1.1        YES NVRAM  down                  down

Serial2                    unassigned      YES NVRAM  administratively down down

Serial3                    unassigned      YES NVRAM  administratively down dow

Now when I remove the cable... here's the status:

[b]*Mar  1 00:06:30.903: %LINEPROTO-5-UPDOWN: Line protocol on Interface Ethernet0,
 changed state to down[/b]LAB_B#sh ip int brief

BRI0:1                     unassigned      YES unset  administratively down down

BRI0:2                     unassigned      YES unset  administratively down down

Ethernet0                  192.168.10.33   YES NVRAM  up                down

Serial1                    10.1.1.1        YES NVRAM  down                  down

Serial2                    unassigned      YES NVRAM  administratively down down

Serial3                    unassigned      YES NVRAM  administratively down dow

2lazybutsmart

If you had some real routers, solving these kinda things would be easy.

the "config_if" thing..... it's supposed to be config-if, is that how boson rights out the router prompt?

Now if you run all those commands, the status of your fastethernet port should come up. If it's not comming up........ i guess that BOSON thing is screwing you.

BAYOUMISOFT

is there another program more nice than BOSON for router's simulation??!!,,

i finished my ccna course with tranining center and i didn't do alot of training and i need help to improve my study and be able to be perfect for enter the exam soon,,

i just need advice

QUIX0TIC

Personally, I really dont think you can beat Boson for the simulation. I know it has its quirks but that is just something you will have to accept.

I just wrote another post regarding prices of a couple of 2501 routers. You can literaly purchase 2 2501 routers for less than 100 bucks and maybe get lucky with them to have full flash/ dram on them with one of the latest IOS. The switches will be a different cost but Im pretty sure you can find a 1924 for less than 50 bucks too.

Ive heard someone actually use a Linksys switch and it worked for them just to plug in a couple of comps.

You can get all this for the same price of the new Boson 5.27 simulator.

johnnynodough

What routers are you using in the sims? The reason I ask is you may have something like a 1710 selected, which has an integrated FA and E ports, and you may be connected to the E port.

ALso on the switch, is the interface shut down, is it in access mode, trunk mode, port security violation?

I'M USING ROUTER 1720 ,,

on the switch, the interface is no shut down, and all ports are access mode, because i didn't change it

BAYOUMISOFT

note:

I'm using last version from Boson,, version 6 beta 3

maybe the problems with the version,,

BAYOUMISOFT

again i had problem with pinging but now with two routers i have,,

i have 2 routers are connected each other ( 1720 )

router A s1 connected to router B s0

after doing " sh ip int br " on router A



after doing " sh ip int br " on router B




i thought this problem with clock rate but when i tried to put clock rate on each interface connected i got this message




so now what is the problem..

really i want solution to complete my next labs because all labs depend on what i do now...

johnnynodough

Im have had bugs with boson Netsim, but nothing ever like that. Tell you what, blow away that lab, and start from scratch redesigning a new one. Config like so.

1720 (Router 1 in NetSIM)
1720 (Router 2 in Netsim)
Switch 1 (SWitch 2 in NetSIm)
Switch2 (Switch 2 in Netsim)

Router 1 Serial 0 (or serial 0/0) connects to router 2 serial 0 (or serial 0/0) router 1 is the DCE side and will provide clocking, Netsim will ask the question

Router 1 FA will connect to switch 1 FA 0/12
Router 2 FA will connect to switch 2 FA 0/12

COnfig Router 1 like so

router>en
router#conf t
router(config)#host router1
router1(config)#int s0
router1(config-if)#ip address 192.168.10.1 255.255.255.0
router1(config-if)#clock rate 64000
router1(config-if)#no shut
router1(config-if)#int fa0
router1(config-if)#ip address 192.168.1.1 255.255.255.0
router1(config-if)#no shut
router1(config-if)#end (or ctrl Z)


Config router 2 like so


router>en
router#conf t
router(config)#host router2
router2(config)#int s0
router2(config-if)#ip address 192.168.10.2 255.255.255.0
router2(config-if)#no shut
router2(config-if)#int fa0
router2(config-if)#ip address 192.168.2.1 255.255.255.0
router2(config-if)#no shut
router2(config-if)#end (or ctrl Z)


Now with that basic config you should have up and up on Serial 0 and FA0 on both routers, this is using default encapsulation HDLC. Once you have everything up, than you can play around with setting up routing protocols, managing your switches, chnaging the encapsulation, access lists, the sky is the limit, you can do a lot with that lab.

how netsim will ask me,, i think all my problem with net sim about clock rate, and how can i know this router is dce??!!

sorry for asking you alot of questions but really i need to help to finish my ccna labs

johnnynodough

In the network designer, you have to assign connections, I think we just found your problem. Right click on the router, click assign connection to (or connect to, cant recall which off the top of my head), a side window will open asking which device to connect to, then another window will opne asking what port to connect to and fro, and if its serial it will ask you if you want a point to point or multipoint connection, you want P to P. After you assign to links, a box will pop up asking you which router will provide clocking.

johnnynodough

And clock rate wont affect your ethernet connections, just serial. When you get that ambiguos command in NetSIm, it means you are trying to apply the command to the DTE side, in CIsco routers it will say "this command only applies to DCE interfaces" but in Netsim it just says Ambigous command.

i tried and i didn't get this box which asking me which router will provide clocking,,

i think there are problem with verison i use so i will try with older version

johnnynodough

Which version (NetSIm LE, NetSIm CCNA, or NEtSIM CCNP) and which version (aka patch rev) are you working with?

Try a different router, try a 2610.

I'm using NEtSIM CCNP ver 6 beta 3,

and this ver is the last version

BAYOUMISOFT

Oh My God,

finally i could find the solution , i tried with another version and everything is ok,,
and all my problems just because the version of Boson, it was 6 beta 3,

but i tried another old version and i could do my work well

really i want thanks johnnynodough so much for replaying all my question and trying helping me ,,
