Common Problems

Telnet Connection Warning

Some Telnet clients will close the Telnet window if the connection cannot be established. This behavior prevents you from seeing error messages that indicate the line is in use, so it’s a good practice to disable this behavior in your Telnet client. If you do not see a command prompt when you establish a Telnet connection, you may need to press Enter to “wake up” the device.

Important Configuration Changes

When you load a saved configuration into the UCS, you must change the interfaces in use to match the Data Center rack you are using; our automation cannot make this modification for you. You will find the necessary configuration changes in the reminder email you receive before your rack session.

Port Speed Information

If you receive an error message stating, “SFP validation failed,” you must manually set the port speed to 1G (1000) because Nexus does not support auto-negotiation from 10G to 1G.

DCrack 8 N5K-5548 Switches

The two N5K switches in DCrack 8 are N5K-5548, unlike all the other racks that use N5K-5020. They do not have a second module in them and use the following wiring to connect to the other devices in the rack.

Device 1 Port 1 Device 2 Port 2
N5K7 1/29 FI-A 1/31
N5K7 1/30 FI-A 1/32
N5K7 1/31 MDS3 FC2/7
N5K7 1/32 MDS3 FC2/8
N5K8 1/29 FI-B 1/31
N5K8 1/30 FI-B 1/32
N5K8 1/31 MDS4 FC2/7
N5K8 1/32 MDS4 FC2/8

Scheduling a Rack Session

You schedule your Data Center rack session through your Members account.

  1. Sign in to the Members site, and then click Rack Rentals on the left side of the page.
  2. Find the rack rental type you want, and click Schedule to see the rack session booking page.
  3. On this page, select a preferred range of start and end dates and start and end times for your rack rental session.
  4. Click Search to find and select available sessions. Click the Book button to reserve your time.

Data Center rack sessions start at designated, set intervals every three hours. You cannot choose a custom start time for Data Center rack rentals at this time. The last half hour of your session is for intersession (the rack is reset for the next customer). For example, if you reserve a 3-hour session, your session will last 2.5 hours; if you reserve a 6-hour session, your session will last 5.5 hours. You are not charged for the intersession portion of your rack rental.

FULLY BOOKED means that the session is not available to rent.
Book means that you may reserve this session. It also displays the number of tokens required to reserve this session.
Rent Now means that the session is available for immediate rental.

Before booking or reserving a session, select any add-ons you want by using the check boxes above the calendar tool.

In the Reserved Sessions area, the Active tab displays any sessions that have already started. These sessions cannot be cancelled. The Upcoming tab displays your reserved sessions, which can be cancelled at any time before the start time of the session.

Passwords

Device IP Address Username/password (case-sensitive)
ESXi1 10.0.115.11 root / cciedc01
ESXi2 10.0.115.12 root / cciedc01
ESXi-VMFEX 10.0.115.21 root / cciedc01
Win2k8-BM 10.0.114.21 Administrator / Cciedc01
N7K and N5K cisco / cisco
MDS cisco / ciscocisco (role = cisco)
UCS 192.168.0.100 cisco / rackpassword (role = admin)

The UCS password is now dynamically changed to match your current rack session password.

Scheduling Data Center Rack Add-ons

Data Center Rack Rentals are modular.

By default, each 'Base 5K/7K' rental includes access to 2 x Nexus 7000 VDCs, 2 x Nexus 5000s, and 2 x Windows Server Virtual Machines.

  • By selecting the UCS/SAN Add-On, you also get access to the UCS Blade Server chassis, UCS 6200 Fabric Interconnects, MDS 9200 SAN Switches, and the Fibre Channel SAN.
  • By selecting the N2K/SAN Add-On, you also get access to the Nexus 2000 Fabric Extenders with a 10GigE attached server, MDS 9200 SAN Switches, and the Fibre Channel SAN.

Note that not all labs require each Add-On. You can determine which labs need which Add-Ons by comparing the Data Center Rack Rental Access Guide CCIE DC Physical Diagram, located in the Resources section in the upper-right corner of this page, with the diagram for the individual workbook section that you are working on.

Use the following general guidelines to help determine which add-ons you need:

  • The Nexus labs require only the Base N5K/N7K rental, unless you are working on the Fabric Extender or SAN labs, in which case they require the N2K/SAN Add-On.
  • The UCS labs require the Base N5K/N7K rental plus the UCS Add-On.

Loading and Saving Configurations

When you load a saved configuration into the UCS, you must change the interfaces in use to match the Data Center rack you are using; our automation cannot make this modification for you. You will find the necessary configuration changes in the reminder email you receive before your rack session.

Before saving any configuration, make sure that all of your devices are at the command prompt or a login prompt.

Canceling a Rack Session

You can cancel a rack session in your Members account.

  1. Click Rack Rentals on the left side of the page, and then click the Upcoming Rentals tab at the top.
  2. To cancel a session, click the red Cancel button in the Upcoming Rentals window.
  3. You will be asked to confirm your cancellation. Another message states the number of tokens that have been returned to your account. Click OK. Your session will be cancelled and your tokens refunded.

Connecting to NX-OS Devices CLI

When your session begins, find your login information on the Rack Rentals page as shown above. Open your terminal software, such as PuTTY, SecureCRT, etc., and telnet to dc.ine.com. Log in with the provided username and password.

dc.rack.access.guide.011

dc.rack.access.guide.012

When you are logged in, a menu displays the devices that you have access to. The example shown below indicates that this session is assigned the Base 5K/7K rental, with both the UCS/SAN and N2K/SAN add-ons.

dc.rack.access.guide.013

Choose the device that you want to connect to, such as N7K1, and log in with the username cisco and password cisco. Note that the default ACE username/password is cisco/ciscocisco.

dc.rack.access.guide.014

Certain commands, such as erasing and reloading the device or editing the management IP address, are purposely restricted to allow the automation system to function properly.

Using the Rack Control Panel

The Rack Control Panel allows you to reset devices to their default configurations and access the remote desktops of the virtual machines. To access the control panel during your active rack session, click Rack Rentals on the Members site, find your session by clicking the Upcoming Rentals tab, and then click the Control Panel button.

Save config and load config functionality will be added to the DC control panel shortly.

Connecting to Virtual Machines

Each rack session is assigned access to certain virtual machines, based on your rack number assignment and the add-ons that you chose. To access the virtual machines:

  1. Go to the Rack Control Panel on the Members site.
  2. Click the Remote Desktop Access tab to see a list of available virtual machines below. If this page asks you for a username and password, use your rack username and password, e.g. username dcrack1 password abcdef.
  3. Click the icon for the VM that you want to access, and the remote desktop will automatically open in another window. The remote desktop's resolution automatically resizes to your browser window size, so if you simply refresh this page the resolution will update to the browser size.

dc.rack.access.guide.034

If for some reason you lock yourself out of a Virtual Machine, you can reset them from the control panel. All changes you made during your rack session will be reverted when you use this option.

Connecting to UCS Blade ESXi Instances

When it becomes necessary to connect to the UCS blade ESXi (or Windows-BareMetal) instances, follow the directions in the task to connect to them, using the VMWare Infrastructure Client provided (preinstalled on any of the Windows VM desktops). The IP addresses for the UCS blade ESXi and Windows Win2k8R2 bare metal instances are:

  • ESXi1: 10.0.115.11
  • ESXi2: 10.0.115.12
  • ESXi-VMFEX: 10.0.115.21
  • Win2k8-BM: 10.0.114.21

The username and password for all ESXi instances are root and cciedc01.

The username and password for the Win2k8R2 instance is Administrator and cciedc01 or Cciedc01.
