16.06.2017, 10:37. Показов 43304. Ответов 4

Всем доброго времени суток,

Начал изучение CCNA. Сейчас выполняю лабораторую работу и столкнулся с такой проблемой:

По заданию нужно сконфигурировать простенькую сетку. Когда открываю лабору в Packet Tracer и пытаюсь открыть меню любого и коммутаторов, мне выдаёт сообщение о том, что настройка залочена (Configure is locked). То есть, скорфигурировать коммутаторы я не могу, потому как доступа к ним у меня нет. Быть может, кто-нибудь сталкивался с такой же проблемой и знает решение, как получить доступ?

Приложил скриншот и саму лабору.

Вы открыли pka-файл — это готовая лаба со своим сценарием, условиями выполнения и, возможно, ограничением времени.
Раз доступа нет — значит условиями лабы он не предусмотрен и обходитесь без него.

Хочется поиграться — собирайте топологию самостоятельно (она, судя по рисунку, проще некуда) — и будет всевозможный доступ.

Я так и сделал, создал и настроил свою топологию. Просто не сталкивался ещё с такими вещами, чтоб доступа не было к устройствам. Просто зачем тогда студентам давать pka-файл, можно ведб просто написать,чтоб создали определённую топологию

Затем и давать, чтобы шли не простейшим и очевиднейшим путем, а демонстрировали некие навыки. Это же контрольная лаба, фактически. Контроль времени есть? Автоматическая проверка правильности выполнения есть? Чего же еще для обучения надо?

Всё оказалось ещё проще. Я просто совершенно забыл,что Packet Tracer позволяет создавать эмуляцию физической сети, а потому из головы совершенно вылетело, что достаточно было к каждому коммутатору добавить консольное соединение, как, если бы я физически находился рядом с ними. После добавления я успешно через терминал получил доступ к обоим коммутаторвм и смог их должным образом настроить.

You can’t unlock it.

1. Access the host PC, double click it then go to Desktop > Command Prompt.
2. Find out the IP address of the router and use the command «telnet xxx.xxx.xxx.xxx» in command prompt, where the x’s is the IP address of said router
3. Wahey, telnet access to the locked router.

Exclusive Configuration Change Access and Access Session Locking

Exclusive Configuration Change Access (also called the “Configuration Lock” feature) allows you to have exclusive change
access to the Cisco IOS XE running configuration, preventing multiple users from making concurrent configuration changes.

The Access Session Locking addition to this feature extends the Exclusive Configuration Change Access feature such that
show and
debug commands entered by the user holding the configuration lock always have execution priority;
show and
debug commands entered by other users are only allowed to run after the processes initiated by the configuration lock owner have
finished.

The Exclusive Configuration Change Access feature (“exposed lock”) is complementary with the locking mechanism in the Configuration
Replace and Configuration Rollback feature (“rollback lock”).

Information About Locking the Configuration

Exclusive Configuration
Change Access and Access Session Locking

Devices running Cisco
IOS software maintain a running configuration that determines the configuration
state of the device. Changes to the running configuration alter the behavior of
the device. Because Cisco IOS software allows multiple users to change the
running configuration via the device CLI (including the device console and
telnet Secure Shell (SSH)), in some operating environments it would be
beneficial to prevent multiple users from making concurrent changes to the
Cisco IOS running configuration. Temporarily limiting access to the Cisco IOS
running configuration prevents inadvertent conflicts or cases where two users
attempt to configure the same portion of the running configuration.

The Exclusive
Configuration Change Access feature (also called the “Configuration Lock”
feature) allows you to have exclusive change access to the Cisco IOS running
configuration, preventing multiple users from making concurrent configuration
changes.

This feature provides
exclusive change access to the Cisco IOS running configuration from the time
you enter global configuration mode by using the
configure
terminal command. This gives the effect of a
“configuration lock,” preventing other users from changing the Cisco IOS
running configuration. The configuration lock is automatically released when
the user exits Cisco IOS configuration mode.

The Exclusive
Configuration Change Access feature is enabled using the
configuration
mode
exclusive command in global configuration mode.
Exclusive configuration change access can be set to
auto , so that
the Cisco IOS configuration mode is locked whenever anyone uses the
configure
terminal command, or it can be set to
manual , so that
the Cisco IOS configuration mode is locked only when the
configure
terminal
lock command is issued.

The Exclusive
Configuration Change Access feature is complementary with the locking mechanism
for the Configuration Replace and Configuration Rollback feature introduced in
Cisco IOS Release 12.2(25)S and 12.3(7)T.

Access Session
Locking

The Access Session
Locking feature extends the Exclusive Configuration Change Access feature such
that
show and
debug commands
entered by the user holding the configuration lock always have execution
priority. This feature prevents concurrent configuration access and also
provides an option to prevent simultaneous processes, such as a
show command
entered by another user, from executing while other configuration commands are
being executed. When this feature is enabled, the commands entered by the user
with the configuration lock (such as configuration commands) always have
priority over commands entered by other users.

How to Configure Configuration Exclusive Confguration Change-Access and Access Session Locking

Enabling Exclusive
Configuration Change Access and Access Session Locking

Note

Effective with
Cisco IOS Release 12.2(33)SRE, the Exclusive Configuration Change Access and
Access Session Locking feature is not available in Cisco IOS software. Use the
Parser Concurrency and Locking Improvements feature instead of this feature.
See the “Enabling Parser Concurrency and Locking Improvements” section for more
information.

Perform this task to enable the Exclusive Configuration Change
Access and Access Session Locking feature.

SUMMARY STEPS

Cisco Switching/Routing :: 3560 Topology In Packet Tracer Related To Etherchannel Configuration

May 23, 2012

i have made a topology in packet tracer related to etherchannel configuration.i am using 2 3560 switches and 1 2950 switch. Now what i want is to bundle up the redundant links between these 3 switches. The links fa0/1-3 between 2950_1 and 3560_1 switches have been bundled up but when i try to bundle the links fa0/4-6 of 3560_1 to fa0/4-6 of 3560_2 it wont work. i am using channel-group 1 mode desirable between the 3560 switches. secondly if i want to assign ip to port channels then it has to be of same subnet between 2 3560 switches right and it must be same between 2950_1 and 3560_1. But these 2 subnets should be different from one another.

Can’t Ping Between Routers (Packet Tracer)

Mar 6, 2011

I’m trying to set up a network comprised of three LANs connected by serial. As this is a small part of an assignment I’ve been instructed to subnet into /26 and to use /30 subnets for my serial connections.At the moment I can ping between devices on each of the LANs but I can’t ping between routers at all. Embarrassingly I’m not sure why, I think it may be something I’ve missed on setting up the serial links as I have set routers up fine before using other connection types.

Cisco :: Simulate An ISA Server In Packet Tracer?

I’m an IT student and I’ve been assigned with homework simulating a network including an ISA server and some clients in Packet Tracer but I can’t find anything which can be configured like an ISA (Internet Security and Acceleration) server(this is kind of Microsoft’s technology as I know) in Packet Tracer, the generic Server from the devices box has only some basic services such as HTTP, DHCP, DNS, FTP, AAA, … but none of anything related to ISA, all the servers in Packet Tracer have only 1 interface whereas the ISA server (as far as I know) should have at least two interfaces, and there is also no CLI supported for those servers so I think I can’t simulate ISA server in Packet Tracer, can I?

Cisco Firewall :: 5550 ASA (8.3) — Packet Tracer / Multi-Context Classification

Nov 22, 2011

I’ve been using packet-tracer for some time on and off with mixed results.

I’m running a multi context firewall with over 10 of the contexts sharing the same outside interface / network. All interfaces obviously have valid, unique IPs and also unique MAC addresses as mac-address auto is enabled in the system context.

This is an ASA 5550 running 8.3(2.10) interim so includes the fix for the well known packet-tracer classication failed bug.

So in theory, with firewall contexts on a shared interface the ASA should use the firewall MAC address to classify incoming traffic to the correct firewall and as far as I am aware, only fall back on using NAT to classify if the interface MACs are the same. In reality on my platform this doesn’t seem to be happening and the classifier is using NAT to determine the destination context. I’m seeing this with live traffic (i.e. not generated by packet-tracer) in logs and can prove it by disabling certain NAT rules (there is some overlap with the IP addressing behind each firewall).

My question regarding packet tracer is this — in the above scenario with a shared outside interface, does packet tracer ALWAYS use NAT to determine the destination context? Or does packet tracer look up the MAC address of the ingress interface according to what context you are running packet tracer from? It appears that packet-tracer is using NAT in my case which could be just symptomatic of the potential bug I’ve described above rather than by design.

Cisco ASA 5505 Simple PAT — Packet-tracer Can’t Look At Any External Devices While Running

Sep 16, 2012

here, am used to the RouterSwitch CLI but been asked to set up an ASA 5505 8.4.Quite simply I am trying to at least test out a static PAT from an external source to an internal server in a test environment and no matter whether I set it up as an auto-nat or a twice-nat whenever I run a packet tracer I end up with the same error. This is the packet-tracer I am running-packet-trace input outside tcp 80.80.80.80 3389 10.240.0.10 3389

Phase: 5
Type: NAT
Subtype: rpf-check
Result: DROP
Config:nat (inside,outside) source static server publicIP service RDP RDP
Additional Information:

[code]….

Now I have a couple of questions initially. I have made the presumption that packet-tracer does not look at any external devices while running — as in as long as the ports are up it doesn’t matter what is on the end of them for testing purposes? Is there anything I am missing?I have this morning wiped the config and have simply set up the adapters, a default route and twice nat and am not sure why I keep getting the error. I am sure it is something very simple and I’m being a massive donut!
