Networking Knowledge

An Ethernet network is a collection of connected system devices. These devices include end-user

desktop computers, centralized file servers, network printers, and other network devices that

communicate with one another.

Common Ethernet network components include PCs, switches, and routers. Networks allow end users to access information and hardware resources. The overall benefit to users who are connected by a

network is an efficiency of operation through commonly available services that are used in everyday

tasks such as sharing files, printing, and storing data.

Traditionally, the LAN manages client-to-server communication, and the SAN is the specialized high- speed network that is designed to transfer data between servers and storage devices.

A SAN allows any-to-any connection across the network, allowing a single server to access an unlimited amount of storage devices including disk, tape, and optical storage. Furthermore, multiple servers can

access the same storage devices across the SAN, providing redundancy on the front end to the clients.

3

In addition to server-to-storage device communication, the SAN allows storage device-to-storage device communication. This enables disk array-to-tape array communication or backup without burning

resources on the server farm.

Internet Small Computer Systems Interface, or iSCSI, is a TCP/IP-based protocol for establishing and managing connections between IP-based storage devices, hosts, and clients.

Internet Fibre Channel Protocol, or iFCP, is a TCP/IP-based protocol for interconnecting Fibre Channel storage devices or Fibre Channel SANs using an IP infrastructure in place of Fibre Channel switching and

routing elements.

Fibre Channel over IP, or FCIP, is a TCP/IP-based tunneling protocol used for connecting geographically distributed Fibre Channel SANs transparently to both Fibre Channel and IP environments.

Ethernet UTP Media Types

The Ethernet specification details several different unshielded twisted-pair (or UTP) media types. These

media types include the following:

_ Ethernet 10BASE-T

_ Fast Ethernet 100BASE-TX

_ Gigabit Ethernet 1000BASE-T

Twisted pair is a copper wire-based cable. UTP cable is one of the most popular of the media that are frequently used in LANs to interconnect all of the network devices.

When used as a networking medium, UTP cable has four pairs of copper wire. Because UTP cable has an external diameter of approximately 0.17 inches, its small size can be advantageous during installation.

There are different quality levels, called categories, of UTP cable:

_ Category 1 can be used for telephone communications; it is not suitable for transmitting data.

_ Category 2 is outdated and is capable of transmitting data at speeds of up to 4 megabits per second, or Mb/s.

_ Category 3 is also outdated and is used in 10BASE-T networks; it can transmit data at speeds up to 10 Mb/s.

_ Category 4 was typically used in an old alternative to Ethernet called Token Ring, and it can transmit data at speeds up to 16 Mb/s.

_ Category 5 is capable of transmitting data at speeds up to 100 Mb/s.

_ Category 5e is used in networks running at speeds up to 1000 Mb/s (1 Gb/s). 4

_ Category 6 consists of 4 pairs of 24-gauge copper wires, which can transmit data at speeds of up to 1000 Mb/s.

The most commonly used categories in LAN environments today are Categories 5e and 6.

UTP is a four-pair cable. Each of the eight individual copper wires in UTP cable is covered by an insulating material, typically plastic. In addition, the wires in each pair are twisted around each other.

And all of the wires are placed in an outer jacket.

The advantage of UTP cable is its ability to cancel interference, because the twisted-wire pairs limit signal degradation from EMI and radio frequency interference (or RFI). To reduce crosstalk between the

pairs in UTP cable, the number of twists in the wire pairs varies.

UTP cable must follow precise specifications regarding how many twists or braids are permitted per meter. The more twists, the better the category of cable. For example, Category 5 UTP has more twists

than Category 4.

The RJ-45 plug is the male component of a UTP cable, crimped at the end of the cable.

As you look at the male connector from the front, the pin locations are numbered from 1 on the left to 8 on the right.

The TIA/EIA has defined two different pin/pair assignment standards: T568A and T568B.

They are nearly identical except that pairs 2 and 3 are reversed.

The Ethernet specification details several different fiber optic media types. These media types include the following:

_ Fast Ethernet 100BASE-FX

_ Fast Gigabit Ethernet 1000BASE-LX

_ Gigabit Ethernet 1000BASE-SX

Fiber Optic Cable

Fiber optic cabling consists of a center glass core surrounded by several layers of protective materials. It

transmits light rather than electronic signals eliminating the problem of electrical interference.

Electronic semi-conductor devices detect the light pulses and convert them to voltages that can then be

reconstructed into data frames. Fiber cable is ideal for connecting networks between buildings due to its

immunity to the effects of moisture and lighting.

Fiber optic cables can be broadly classified into two types: single-mode and multimode.

5

Single-Mode cable is a single strand of glass fiber with a relatively narrow diameter that has one mode of transmission. The small core and single light-wave virtually eliminate any distortion, providing the

highest transmission speeds of any fiber cable type. It carries higher bandwidth than multimode fiber,

but requires a light source with a narrow spectral width like laser light. Single-mode fiber gives you a

higher transmission rate and up to 50 times more distance than multimode, but it also costs more.

Multimode fiber has a larger core-size than single-mode fiber, with common diameters for its light carrying component. It typically uses LED emitters that do not create a single coherent light wave. Light

waves are dispersed into numerous paths, or modes, as they travel through the cable's core. Multimode

fiber gives you high bandwidth at high speeds over medium distances.

There are various connectors for fiber optic cable. Some of the most common fiber connectors in a LAN include the following:

_ Straight-tip (or ST) is a barrel-shaped connector, similar to a BNC connector and that is widely used with multimode fiber.

_ Subscriber connector (or SC) is a connector that has a square face. SC uses a push-pull mechanism to ensure positive insertion and is easier to connect in a confined space. This connector type is widely used

with single-mode fiber.

_ Lucent connector (or LC) is a small connector that is becoming popular for use with single-mode fiber and that also supports multimode fiber.

6

Cisco Connectors

Many Cisco devices support the use of two generic interfaces:

_ Gigabit Interface Converter (or GBIC), and

_ Small form-factor pluggable (or SFP)

These interfaces support the use of GBIC and SFP modules or adapters. GBIC modules and SFP modules are I/O devices that plug into a Cisco router or a switch port, linking the port with many different fiber or

copper media. This feature provides administrators with flexibility when integrating Cisco devices by

accommodating various fiber and copper connector types.

The GBIC and SFP modules are inserted into the corresponding GBIC or SFP port of the device, and then the media are plugged into the adapter.

Switches in the Cisco Nexus Series have two main command modes: user EXEC mode and configuration mode. The commands that are available to you depend on the mode that you are in. To obtain a list of

available commands in either mode, type a question mark at the system prompt.

As a security feature, Cisco NX-OS software separates the EXEC sessions into the following two access levels:

_ User EXEC mode allows a person to access only a limited number of basic monitoring commands.

40

_ Privileged EXEC mode allows a person to access all device commands, such as those used for configuration and management. Privileged EXEC mode can be password protected to allow only

authorized users to access the device.

To enter commands into the CLI, either type or paste the entries within one of the several console

command modes. Each command mode is indicated with a distinctive prompt.

Cisco NX-OS CLI

The Cisco NX-OS CLI has a hierarchy of different command modes. Each command mode supports

specific Cisco NX-OS commands that are related to a type of operation on the device, and each mode

has a distinct prompt.

When you are at the user EXEC prompt, you must access privileged EXEC mode to make configuration changes. The command that you use to do this is enable.

From privileged EXEC mode, you can enter the subconfiguration modes of global configuration mode. Commands that affect the entire router or switch, such as setting hostnames and passwords, are

configured from global configuration mode. To enter global configuration mode, at the privileged EXEC

prompt, you enter the configure terminal command.

Subsequently, from global configuration mode, you have access to the subconfiguration modes, which includes interface configuration mode. Interface configuration mode supports commands that configure

operations on a per-interface basis, such as setting speed and duplex.

To enter interface configuration mode on a switch from the CLI, you use a three-part syntax: Interface type; group number of module; then a slash, followed by the module port number. Each individual port

on the Cisco Nexus switches is numbered, and groups of ports are numbered based on their function.

The ports are numbered top to bottom and left to right.

If you enter the exit command, the router backs out one level and eventually logs out.

In general, you enter the exit command from one of the specific configuration modes to return to global configuration mode. By pressing the Ctrl-Z key sequence or by entering the end command, you can leave

any configuration mode completely and return the router to the privileged EXEC mode.

41

Saving the Active Configuration as a Backup

The copy run start command creates a backup of the active configuration. The following figure shows

how to verify active and backup configurations.

43

The show running-config command displays the current running configuration.

The show startup-config command displays the configuration saved in NVRAM that will be used on the next bootup.

Step 3: Slide the blade partway out of the chassis, and place your other hand under the blade to support its weight.

Step 4: After you have removed the blade, place the blade on an antistatic mat or antistatic foam if you are not immediately reinstalling it into another slot.

Step 5: If the slot will remain empty, install a blank faceplate (N20-CBLKB1) to keep dust out of the chassis.

The figure shows the positioning of a blade server in the chassis. To install a blade server, refer to the figure and follow these steps:

Step 1: Grasp the front of the blade server and place your other hand under the blade to support it.

Step 2: Open the ejector lever in the front of the blade server.

Step 3: Gently slide the blade into the opening until you cannot push it any farther.

Step 4: Press the ejector lever so that it catches the edge of the chassis and presses the blade server all the way in.

Step 5: Tighten the captive screw on the front of the blade to no more than 3 lbs. Tighten it with bare fingers only to avoid stripping or damaging the screw.

Step 6: Power on the server. Cisco UCS Manager automatically reacknowledges, reassociates, and recommissions the server, as long as the hardware changes are allowed by the service profile.

Blade servers reside within the eight upper slots of the chassis.

KVM cable (N20-BKVM)

The KVM cable (N20-BKVM) provides a connection into a Cisco UCS 5108 Blade Server, providing a DB9

serial connector, a VGA connector for a monitor, and dual USB ports for a keyboard and mouse. With

this cable, you can create a direct connection to the operating system and the BIOS running on a blade

server.

_ The connector labeled 1 is the connector to the blade server slot.

_ The connector labeled 2 is the DB9 serial connector.

_ The connector labeled 3 is the VGA connection for a monitor.

_ The connector labeled 4 is the two-port USB connector for a mouse and keyboard.

Replacing a Cisco UCS C-Series Device

The physical replacement of a Cisco UCS C-Series device includes several steps. First, shut down and

power off the server. The server can run in the following two power modes:

_ Main power mode: Power is supplied to all server components, and any operating system on your hard drives can run.

_ Standby power mode: Power is supplied only to the service processor and the cooling fans, and it is safe to power off the server from this mode.

56

You can invoke a graceful shutdown or an emergency shutdown (also known as a hard shutdown). To use the power button on the server front panel, follow these steps:

Step 1: Check the color of the power status LED:

_ Green indicates that the server is in main power mode and must be shut down before it can be safely powered off. Go to Step 2.

_ Amber indicates that the server is already in standby mode and can be safely powered off. Go to Step 3.

Step 2: Invoke either a graceful shutdown or a hard shutdown. Caution: To avoid data loss or damage to your operating system, you should always invoke a graceful shutdown of the operating system.

_ Graceful shutdown: Press and release the power button. The operating system performs a graceful shutdown, and the server goes to standby mode, which is indicated by an amber power status LED.

_ Emergency shutdown: Press and hold the power button for four seconds to force the main power off and immediately enter standby mode.

Step 3: Disconnect the power cords from the power supplies in your server to completely power off the server.

Remove a server from a rack

To remove a server from a rack, use the following steps:

Step 1: Disconnect all cables from the server. You can leave the cables routed through the CMA.

Step 2: Loosen the two captive thumbscrews that secure the front of the server to each rack post.

Step 3: Pull the server out of the front of the rack until the slide rails stop against the internal lock.

Step 4: Press the removal release clip on each slide rail and then continue pulling the server out evenly until it clears the slide rails.

To replace a server in a rack, use the following steps:

Step 1: Align the mounting brackets that are attached to the server sides with the front of the empty slide rails.

Step 2: Push the server into the slide rails until they stop against the internal stops.

Step 3: Press the installation release clip on each slide rail and then continue pushing the server in evenly until its front flanges touch the rack posts.

Step 4: Tighten the thumbscrews on each flange to secure the server to the rack posts.

Upgrading the BIOS on a Cisco UCS Server Blade with the GUI

To upgrade the BIOS on a server blade or a server pool, you must create a host firmware that has these

components, and then push it to all servers that are associated with service profiles that include this

policy.

This Host Firmware Package policy ensures that the host firmware is identical on all servers that are associated with service profiles that use the same policy. Therefore, if you move the service profile from

one server to another, the firmware versions are maintained.

You must include this Host Firmware Package policy in a service profile, and that service profile must be associated with a server for it to take effect.

If you associate a new Host Firmware Package policy to a service profile that is currently linked to blades, it causes those blades to reboot. You must decide if you want to disassociate the service profile

before the new firmware package policy is applied.

If a server blade is currently associated with a service profile, you can choose to disassociate the blade before the BIOS upgrade is performed. Use the following steps:

Step 1: In the Navigation pane, click the Servers tab.

Step 2: In the Servers tab, expand Servers > Service Profiles.

Step 3: Expand the node for the organization that contains the service profile that you want to disassociate from a server or server pool. If the system does not include multitenancy, expand the root

node.

Step 4: Click the service profile that you want to disassociate with a server and choose Disassociate Service Profile.

Step 5: In the Disassociate Service Profile dialog box, click Yes to confirm that you want to disassociate the service profile.

Step 6: Click OK. If you want, monitor the status and the finite state machine (FSM) for the server to confirm that the disassociation completes.

To upgrade the BIOS on a Cisco UCS Server Blade using Cisco UCS Manager, use the following steps:

Step 1: Verify that the correct BIOS is present in the fabric interconnect flash.

Step 2: Create the Host Firmware Package policy with the desired BIOS version:

_ In the Navigation pane, choose the Servers tab.

_ On the Servers tab, expand Servers > Policies.

58

_ Expand the node for the organization where you want to create the policy. If the system does not include multitenancy, expand the root node.

_ Right-click Host Firmware Packages, and choose Create Host Firmware Package.

_ In the Create Host Firmware Package dialog box, enter a unique name and description for the package. This name can be between 1 and 16 alphanumeric characters. You cannot use spaces or any special

characters, and you cannot change this name after the object is saved.

_ Click the down arrows to expand one or more of the sections on the left of the dialog box, and choose BIOS Firmware Packages.

_ When you have added all the desired firmware to the package, click OK.

_ Double-click to choose the BIOS firmware. Click OK to confirm that the Host Firmware Package policy is created.

Associate the created Host Firmware Package policy to a service profile. This association automatically updates and activates the firmware in the server and adapter with the new versions and reboots the

server. Use the following steps:

_ In the Navigation pane, click the Servers tab.

_ On the Servers tab, expand Service Profiles.

_ Choose the desired service profile.

_ On the right pane, click the Policies tab of the selected service profile.

_ Click the Firmware Policies drop-down list and choose the previously created host firmware package from the Host Firmware menu.

_ Save the changes.

If your service profile is currently associated with a server, this change causes an immediate server reboot with the BIOS installation. If your service profile is not associated with a server, apply it to a

blade for the BIOS upgrade to take effect.

59

Associate the service profile with a server blade or server pool. After the Host Firmware Package policy is assigned and saved, associate this policy to the service profile that is used by the blade server, and

monitor the KVM output to see the new BIOS displayed. The BIOS upgrade should not extend the

bootup time of the blade.

Step 1: Click the General tab.

Step 2: Click Change Service Profile Association.

Step 3: In the Associate Service Profile window, choose the appropriate server or server pool, and click OK to push the new BIOS to the server.

Verify that the BIOS version of the blade matches the BIOS for the Host Firmware Package policy.
