Chapter 1: Avaya C360 Overview

The C360 is a line of converged stackable switches that provide high availability, quality of service (QoS), and IEEE 802.3af Power over Ethernet (PoE) to enhance converged network infrastructure operations. With a range of PoE and non-PoE configurations, the C360 series is a powerful, yet cost-effective option for enterprise applications.

With C360 switches, you can deploy PoE and multilayer switching using one switch, while maintaining the simplicity and the cost effectiveness of Avaya stackable switches.

C360 Features and Benefits

Stacking

● You may create logical stacks of up to ten switches that you manage and configure as a

single switch.

● C363T

● C363T-PWR

● C364T

● C364T NEBS

● C364T-PWR

● C363T-PWR

● C364T-PWR

● Stacking is based on the Octaplane™ stacking system that provides eight Gbps stacking

bandwidth to all switches in the stack.

● Each member of the stack is connected to the other members using a dedicated stacking

module and cables.

Issue 1 July 2006 19

Avaya C360 Overview

● When the switches are stacked, the switches elect one switch as the master, while the

other switches act as slaves. The master switch acts as the stack management agent reporting to the management system.

● Management redundancy - if the master unit fails, the remaining switches elect a new

switch as the master, and the original stack configuration and IP address are maintained.

● You can add, remove and replace switches in the stack without disrupting operation.

● Auto-reconfiguration for replaced switch - the configuration of the units is distributed over

the stack. When you replace a unit, you do not need t o reconfigure st ack-level p arame ters such as Spanning Tree, IP address and port redundancy.

Network Optimization

● Autosensing of port speed and autonegotiation of duplex mode on all switch ports for

optimizing bandwidth.

● IEEE 802.3x flow control on all Ethernet ports.

● Auto MDI/MDI-X (cross-over cable) detection allows use of both straight and crossover

cables without the need to configure ports individually.

● LAGs (Link Aggregate Group) provide enhanced fault tolerance and aggregated

bandwidth of up to 800 Mbps (on 10/100BASE-T ports) or 2 Gbps (on 1000BASE-X ports).

- Ideal for high-bandwidth connections to servers, routers and switches.

- Refer to LAG (Link Aggregate Group)

● IGMP (Internet Group Management Protocol) Snooping for limiting flooding of multicast

traffic.

Manageability

● SNTP (Simple Network Time Protocol) or TIME protocol for providing a consistent

timestamp to all switches from an external source. Refer to Network Time Acquiring

Protocols Parameter Configuration on page 97.

● In-band management access:

- C360 Device Manager with intuitive Web-based access. Refer to C360 Device

Manager on page 193 for further information.

- Up to five simultaneous Telnet connections for multiple CLI (Command Line Interface)-based sessions over the network. Refer to Establishing a Telnet

Connection on page 65 for further information.

20 Installation and Configuration Guide Avaya C360 Multilayer Stackable Switches, version 4.5

C360 Features and Benefits

- Up to two simultaneous encrypted SSH (Secure Shell) connections for multiple CLI-based sessions over the network. Refer to Establishing an SSH Connection

page 66 for further information.

- SNMP (Simple Network Management Protocol) "get" and "set" requests (support for SNMPv1, SNMPv2 and SNMPv3). Refer to SNMP Support

on page 73 for further

information.

● Out-of-band management access through the switch console port to a directly attached

terminal or remote terminal via a serial connection or modem. Refer to Establishing a

Console Connection on page 62 and Establishing a Modem (PPP) Connection on page 71

for further information.

● Allowed managers to restrict access to a pre-defined list of IP addresses. Refer to Allowed

Managers on page 84 for further information.

● Software upgrades by TFTP. Refer to Firmware Download on page 211 for further

information.

● Configuration upload/download by TFTP and SCP. Refer to Uploading and Downloading

Device Configurations and Images on page 99 for further information.

● "Allowed protocols" allows you to selectively enable and disable the IP protocols. Refer to

Allowed Protocols

on page 86 for further information.

Redundancy

● IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) for rapid convergence of the spanning

tree by immediately transitioning root and designated ports to the forwarding state.

- RSTP automatically detects switches that are configured as 802.1w Rapid Spanning Tree or 802.1D Spanning Tree and operates accordingly. Refer to Spanning Tree

Protocol on page 127 for further information.

- Edge port for eliminating the forwarding delay by enabling a port to immediately transition from the blocking state to the forwarding state.

● Port redundancy provides a backup for important links. If one link fails, the backup link

takes over , preventing disruption to network tra ffic. Refer to Port Redundancy for further information.

● Inter-module redundancy is hardware-based and intended for important links that need to

be maintained even if there are changes in the stack. Refer to Intermodule Port

Redundancy on page 137 for further information.

● Port redundancy combined with 802.1w provides configuration flexibility in complex

network configurations.

● LAG redundancy adds the reliability of port redundancy to LAGs, thus providing inter-port

as well as intra-port redundancy.

Issue 1 July 2006 21

Avaya C360 Overview

● Stack redundancy - in the unlikely event that a C360 switch or Octaplane link should fail,

stack integrity is maintained if the redundant cable is connected to the stack. The broken link is bypassed and data transmission continues uninterrupted.

● BUPS (Backup Power Supply) - you can connect an additional DC power supply to the

BUPS connectors to ensure no disruption if the internal PSU fails. Refer to Connecting a

BUPS on page 53 for further information.

VLAN Support

● Support for up to 3,071 VLANs (in the range of 1-3071) according to the IEEE 802.1Q

standard for assigning VLANs associated with appropriate network resources, traffic patterns, and bandwidth. Refer to VLANs

● IEEE 802.1Q lets a VLAN span multiple switches. This provides management and control

of broadcast and multicast traffic and network security as well as all the other benefits of VLANs over the entire network.

● PVID - VLAN-per-port for maximum flexibility and security.

Management

The C360 switch is designed for plug-and-play operation: you need to configure only basic IP information for the switch and connect it to the other devices in your network. If you have specific network needs, you can configure and monitor the switch - individually or as part of a stack - through its various management interfaces.

Management Interface Options

You can configure and monitor individual switches and the entire stack by using these interfaces:

● The built-in C360 Device Manager allows you to configure and manage a C360 stack

using a Web browser without purchasing additional software. This application works with the Microsoft Internet Explorer and Netscape Navigator web

browsers and Sun Microsystems Java Plug-in.

● CLI - You can configure and monitor the switch or the stack from the CLI. You can access

the CLI either by connecting your management station directly to the switch console port or by using Telnet, PPP or SSH from a remote management station.

● SNMP - provides a means to monitor and control the switch or the stack. Y ou can manage

switch configuration settings, performance, security, and collect statistics by using SNMP management applications such Avaya Integrated Management and HP OpenView.

Establishing Switch Access

CLI Architecture

The C360 stack supports both Layer 2 switching and Layer 3 switching. The C360 CLI includes two CLI entities to support this functionality.

● The Switch CLI entity is used to manage Layer 2 switching of the entire stack. CLI

commands for managing Layer 2 switching are described in the Reference Guide for the Avaya C360 Converged Stackable Switch, 10-300506.

● The Router CLI entity is used to manage Layer 3 switching of a single module. CLI

commands for managing Layer 3 switching are described in the Reference Guide for the Avaya C360 Converged Stackable Switch, 10-300506.

To switch between the entities, use the session command.

Security Levels

There are three security access levels - User, Privileged, and Supervisor.

● The User level ('read-only') is a general access level used to show system parameter

values.

● The Privileged level ('read-write') is used by site personnel to access stack configuration

options.

● The Supervisor level ('administrator') is used to define user names, passwords, and

access levels of up to 10 local CLI users, configure SNMPv1 community, configure SNMPv3, configure RADIUS authentication and control access protocols to the device.

Tip:

Tip: If you wish to define more than ten users per switch, or accounts for a user on

multiple switches, use RADIUS (Remote Authentication Dial-In User Service).

A login name and password are always required to access the CLI and the commands. The login name, password, and access-type (i.e., security level) for a user account are established using the username command.

Switching between the entities does not effect the security level since security levels are established specifically for each user. For example, if the operator with a privileged security level in the Switch entity switches to the Router entity, the privileged security level is retained.

Tip:

Tip: If you wish to increase security, you can disable SNMPv1 and allow only

SNMPv3.

Establishing Switch Access

Assigning C360 IP Stack Address

Note:

Note: All C360 switches are shipped with the same default IP address. You must

change the IP address of the master C360 switch in a stack in order to guarantee that the stack has its own unique IP address in the network.

The network management station or a workstation running a Telnet client can establish communications with the stack once this address had been assigned and the stack has been inserted into the network. Use the CLI to assign the C360 stack an IP address and net mask.

To assign a C360 IP stack address:

1. Establish a serial connection by connecting a terminal to the master C360 switch of the stack.

2. When prompted for a Login Name, enter the default name root

3. When you are prompted for a password, enter the password root. You are now in Supervisor Level.

4. At the prompt, type: set interface inband <vlan> <ip_address> <netmask> Replace <vlan>, <ip_address> and <netmask> with the VLAN, IP address, and net mask of the stack.

5. Press Enter to save the IP address and net mask.

6. At the prompt, type reset. Type y and press Enter to reset the sta ck. After the Reset, log in again as described above.

- At the prompt, type set ip route <dest> <gateway> and replace <dest> and <gateway> with the destination and gateway IP addresses.

64 Installation and Configuration Guide Avaya C360 Multilayer Stackable Switches, version 4.5

Establishing a Telnet Connection

Perform the following steps to establish a Telnet connection to the C360 for configuration of Stack or Router parameters. You can Telnet the Stack Master IP address:

1. Connect your station to the network.

2. Verify that you can communicate with the C3 60 by ping ing the IP of the C360. If there is no response using ping, check the IP address and default gateway of both the C360 and the station.

Tip:

Tip: The C360 default IP address is 149.49.32.134 and the default subnet mask is

255.255.255.0.

3. From the Microsoft Windows taskbar of your PC click Start and then Run (or from the DOS prompt of your PC), then start the Telnet session by typing: telnet <C360_IP_address> For example: telnet 149.49.32.134

4. If the IP Address in the Telnet command is the IP address of the stack, then connection is established with the Switch CLI entity of the Master module.

Establishing a Telnet Connection

● The "Welcome to C360" screen appears

5. Enter the default name root at the Login name prompt.

6. Enter the User Level password root in lower case letters (do not use uppercase letters) at the Password prompt.

● The User level prompt will appear when you have established communications with the

C360. You can now configure the C360 stack and change its IP address.

Establishing an SSH Connection

Introduction to SSH

SSH (Secure Shell) protocol is a security protocol that enables establishing a remote session over a secured tunnel, also called a remote shell. SSH accomplishes this by creating a transparent encrypted channel between the local and remote devices. In addition to remote shell, SSH also provides secure file transfer between the local and remote devices.

SSH protocol currently has 2 versions, SSH1 and SSH2. SSH2 provides better security protection, key distribution services, and public key certificates than SSH1. SSH2 also has modular architecture which enables extension authentication and encryption techniques superior to SSH1. The OpenSSH package that Avaya uses for SSH implementation only supports SSH2.

SSH uses password authentication. A maximum of two SSH sessions can be active per router in the stack, with two additional active

SSH sessions per stack. For example, if a stack contains three router modules, a maximum of eight SSH sessions can be active on the stack.

The C360 agent reports SSH sessions opened to it. In addition, each router module report s t he SSH sessions opened to its router interface. You can disconnect selected SSH sessions.

The SSH session-establishment process is divided into the following stages, as shown in

Figure 21

SSH client connection:

To connect the SSH client:

1. The C360 and the SSH client initiate protocol handshake by exchanging the version number and list of supported ciphers. This step is completed by agreement on the cipher to be used for SSH secure tunnel. In addition, the client sends the C360 a unique session id used to prevent replay attack.

2. The Diffie-Hellman protocol is then used to setup the shared session key. During this step, the client and C360 exchange the DH (Diffie-Hellman) p arameters, i.e., the prime nu mber p and the generator number g used by each party for deriving its private and public keys.

3. The client sends to C360 min., max and preferred values for p and the C360 sends client p and g values. In response, the client uses them to derive its DH private key x and its DH public key values by exponentiation of g with x, e = (g^x)mod p and sends the value e to the C360

66 Installation and Configuration Guide Avaya C360 Multilayer Stackable Switches, version 4.5

Establishing an SSH Connection

4. The C360 derives its DH private key y and its DH public key f=(g^y)mod p, and sends the f value to the client, its public host key and the digital signature calculated for all values exchanged so far including f and public host key. The C360 uses DSA cipher and its host private key to calculate the signature.

5. The SSH client verifies the C360 identity. It checks the C360 host public key validity against the ~/.ssh/known_host file. This is the prompt that user receives if he or she connects to an unknown SSH server. It checks the known_hosts file for the host key offered by the server and prompts if it is not there or if it has changed

6. The SSH client verifies digital signature by decrypting it with DSA and the C360 host public key. This and the step above are essential to prevent a "man-in-the middle" attack by someone taking the C360 identity.

7. Using combination of each other public keys and their own private keys both parties now to calculate Diffie-Hellman shared secret. C360 calculate the shared secret K=f^x mod p and the client calculates K=e^ymod p. Both end up with the same value because of commutativity of exponentiation. The shared key is never sent on wire ensurin g it s secrecy. The shared session key used then for deriving the TDES symmetric key. All messages exchanged between the parties from this point are encrypted with TDES using the derived TDES key.

User Authentication

Before any data is transferred, the C360 requires the client to supply a user name and static password. This authenticates the user on the client side to the C360.

Establishing Switch Access

Establishing Access to Other Entities in the Stack (C360 Sessions)

You can use sessions to switch between the CLI of C360 switches, other stack entities, or to switch between Layer 2 and Layer 3 commands.

To switch between stack entities use the session [<mod_num>] <mode> CLI command.

● <mod_num> is the number of the switch in the stack, counting from the bottom.

● <mode> can be switch, router, wan, or mgp.

Use switch mode to configure layer 2 commands. Use router mode to configure routing commands. Examples: To configure router parameters in the module that you are currently logged into, type the

following command:

session router

To configure the switch parameters, on switch 6, type the command: session 6 switch.

Note:

Note: When you use the session CLI command the security level stays the same.

Point-to-Point Protocol (PPP) provides a Layer 2 method for transporting multi-protocol datagrams over modem links.

Connecting a Modem to the Console Port

Before you can establish a PPP connection with a modem can be established, you need to configure the following:

● C360 IP address: refer to Assigning C360 IP Stack Address for further information.

● net-mask

● PPP parameters that are compatible with the modem's PPP parameters.

1. Connect a terminal to the console port of the C360 switch as described in Connecting a Terminal to the C360 Serial port.

2. When you are prompted for a Login Name, enter the default name root.

3. When you are prompted for a password, enter the password root. You are now in Supervisor Level.

4. At the prompt, type: set interface ppp <ip_addr> <net-mask> with an IP address and netmask to be used by the C360 to connect via its PPP interface.

Note:

Note: The PPP interface configured with the set interface ppp command must be

on a different subnet from the stack inband interface.

5. Set the baud rate, ppp authentication, and ppp time out required to match your modem. These commands are described in the Reference Guide for the Avaya C360 Converged Stackable Switch, 10-300506.

6. At the prompt, type:

set interface ppp enable

● The CLI responds with the following:

Entering the Modem mode within 60 seconds... Please check that the proprietary modem cable is plugged into the console port

7. Use the DB-25 to RJ-45 connector provided in the accessory kit to plug the console cable to the modem's DB-25 connector. Plug the other end of the cable RJ-45 connector to the C360 console's RJ-45 port.

8. The C360 enters modem mode.

SNMP Support

Introduction to SNMP

SNMP Versions

There are currently three versions of SNMP (Simple Network Management Protocol):

● SNMPv1

● SNMPv2c

● SNMPv3

The C360 supports device access using all three versions of SNMP.

Managers and Agents

SNMP Support

SNMP uses software entities called managers and agents to manage network devices. The manager monitors and controls all other SNMP-managed devices or network nodes on the network. There must be at least one SNMP Manager in a managed network. The manager is installed on a workstation located on the network.

An agent resides in a managed device or network node. The agent receives instructions from the SNMP Manager, generates reports in response to requests from the SNMP Manager, and also sends management information back to the SNMP Manager as events occur. Each C360 module has an agent. However, on each C360 stack, one module is selected to be the master module. The stack is managed via the master module's agent.

There are many SNMP management applications, but all these applications perform the same basic task. They allow SNMP managers to communicate with agent s to config ure, g et statistics and information, and receive alerts from network devices. You can use any SNMP-compatible network management system to monitor and control the C360.

Manager/Agent Communication

There are several ways that the SNMP manager and the agent communicate. The manager can:

● Retrieve a value - a get action

The SNMP manager requests information from the agent, such as the link status of an Ethernet port or the number of good packets received on the switch. The agent gets the value of the requested MIB variable and sends the value back to the manager.

Issue 1 July 2006 73

Establishing Switch Access

● Retrieve the value immediately after the variable you name - a get-next action.

The SNMP manager retrieves values from the MIB tree. Using the get-next function, you do not need to know the exact variable name you are looking for. The SNMP manager takes the variable you name and then uses a sequential search to find the desired variable.

● Change a setting on the agent - a set action

The SNMP manager requests the agent to change the value of the MIB variable. For example, you can enable or disable a port.

● An agent can send an unsolicited message to the manager at any time if a significant,

predetermined event takes place on the agent. This message is called a trap. When a trap condition occurs, the SNMP agent sends an SNMP trap message to the

specified trap receiver or trap host. The SNMP Administrator configures the trap host, usually the SNMP management station, to perform the action needed when a trap is detected.

SNMPv1

SNMPv1 uses community strings to limit access rights. Each SNMP device is assigned to a read community and a read-write community. To communica te with a switch, you must send an SNMP packet with the relevant community name.

By default, if you communicate with a switch using only the read community, you are assigned the security name "ReadCommN". This security name is mapped to the "ReadCommG" group by default. This allows you to view the agent's MIB tree, but cannot change any of the values in the MIB tree.

If you communicate with a switch using the write community, you are assigned the security name "WriteCommN". This security name is mapped to the "W riteComm" group by default. This allows you to view the agent's MIB tree and change any of the values in the MIB tree.

CAUTION: If you delete the ReadCommN or WriteCommN users, the ReadCommG or

In addition, traps are sent to designated trap receivers. Packets with trap information also contains a trap community string.

SNMPv2c

CAUTION:

SNMPv2c is very similar to SNMPv1. However, SNMPv2c adds support for the get-bulk action and supports a different trap format.

SNMPv3

SNMPv3 enables the following features over SNMPv1 or v2c:

● User authentication with a username and password. Authentication is performed using

● Communication encryption between the Network Management Station (NMS) and the

● Access control definition for specific MIB items available on the SNMP agent

● Notification of specified network events directed toward specified users

● Definition of roles using access control, each with unique access permissions and

The basic components in SNMPv3 access control are users, groups, and views. In addition. SNMPv3 uses an SNMP engine ID to identify an SNMP entity. An SNMP engine ID

is assigned to each IP address of each device in the network. Each SNMP engine ID should be unique in the network.

SNMP Support

md5 or sha-1.

authentication/encryption requirements

Users

SNMPv3 uses the User-based Security Model (USM) for security, and the View-based Access Control Model (VACM) for access control. USM uses the HMAC-MD5-96 and HMAC-SHA-96 protocols for user authentication, and the CBC-DES56 protocol for encryption.

A maximum of 21 users, including local users and remote users getting notifications can be defined on a stack. If the SNMP engine ID changes, all users other than the default user for the stack are invalid and must be redefined. The SNMP engine ID can be changed via the CLI. In addition, a change in the IP address of the stack automatically changes the SNMP engine ID.

SNMPv3 supports three security levels:

● NoAuthNoPriv - This is the lowest level of SNMPv3 security . No authentication is done and

no encryption is performed. This method is maintains the same security level as SNMPv1, but provides a method for limiting the access rights of a user.

● AuthNoPriv - User authentication is performed based on MD5 or SHA algorithms. The

message is sent with an HMAC that is calculated with the user key. The data part is sent unencrypted.

● AuthPriv - User authentication is performed based on MD5 or SHA algorithms. 'The

message is sent with HMAC for authentication, and encrypted using DES.

To create an SNMPv3 user account, you must provide the following information:

● UserName - string representing the name of the user.

● Maximum length: 32 characters.

Issue 1 July 2006 75

Establishing Switch Access

● Authentication Protocol - The authentication protocol to use. Possible values are: No auth,

HMAC MD5, or HMAC SHA-1.

● Authentication Password - The authentication password is transformed using the

authentication protocol and the SNMP engine ID to create an authentication key.

● Privacy Protocol - The privacy protocol to use. Possible values are: No privacy, DES

privacy.

● Privacy Password - The privacy password is transformed using the privacy protocol and

the SNMP engine ID to create a privacy key.

● GroupName - a string of up to 32 characters representing the name of the group.

● SecurityModel - The security model to use. Possible values are: 1 (SNMPv1), 2

(SNMPv2c), 3 (USM).

Groups

In SNMPv3, each user is mapped to a group. The group maps it s users to defined views. These views define sets of access rights, including read, write, and trap or inform notifications the users can send.

The group maps its users to views based on the security model an d level with which th e user is communicating with the switch. Within a group, the following combinations of security model and level can be mapped to views:

● SNMPv1 - Only requests using SNMPv1 or higher.

● SNMPv2c - Only requests using SNMPv2 or higher.

● NoAuthNoPriv - An SNMPv3 user using the NoAuthNoPriv security level.

● AuthNoPriv - An SNMPv3 user using the AuthNoPriv security level.

● AuthPriv - An SNMPv3 user using the AuthPriv security level.

If a group with the specific security model and level does not exist, then a user can access a group with lower security model or level. If an SNMPv3 group with NoAuthNoPriv security level is not defined, SNMPv3 users with a NoAuthNoPriv security level can access the SNMPv2c view.

To create an SNMPv3 group, you must provide the following information:

● GroupName - String of up to 32 characters representing the name of the group.

● Security model:

-SNMPv1

-SNMPv2c

-SNMPv3

● Security level (for SNMPv3 only):

- NoAuthNoPriv

76 Installation and Configuration Guide Avaya C360 Multilayer Stackable Switches, version 4.5

Views

SNMP Support

- AuthNoPriv

- AuthPriv

● View names:

- Read - Allow read-only access to a specified list of Object IDs (OIDs) in the MIB tree.

- Write - Allow read-write access to a specified list of OIDs in the MIB tree.

- Notify - Allow SNMP notifications from a specified list of OIDs to be sent.

Each view consists of a name and a list of OIDs in the MIB tree. This list can be created using multiple "snmp-server view" commands to either add OIDs to the list or exclude OIDs from a list of all of the OIDs in the switch's MIB tree.

You can use wildcards to include or exclude an entire branch of OIDs in the MIB tree, using an asterisk instead of the specific node.

To create an SNMPv3 view, you must provide the following information:

● ViewName - a string of up to 32 characters representing the name of the view.

● ViewType - Indicates whether the specified OID is included or excluded from the view.

● OIDs - A list of the OIDs accessible using the view.

RADIUS

Introduction to RADIUS

User accounts are typically maintained locally on the switch. Therefore, if a site contains multiple Avaya Switches, it is necessary to configure each switch with its own user accounts. Additionally, if for example a "read-write" user has to be changed into a "read-only" user, you must change all the "read-write" passwords configured locally in every switch, in order to prevent him from accessing this level. This is obviously not effective management. A better solution is to have all of the user login information kept in a central location where all the switches can access it. C360 features such a solution: the Remote Authentication Dial-In User Service (RADIUS).

A RADIUS authentication server is installed on a central computer at the customer's site. On this server user authentication (account) information is configured that provides various degrees of access to the switch. The C360 will run as a RADIUS client. When a user attempts to log into the switch, if there is no local user account for the entered user name and password, then the switch will send an Authentication Request to the RADIUS server in an attempt to authenticate the user remotely. If the user name and password are authenticated, then the RADIUS server responds to the switch with an Authentication Acknowledgement that includes information on the user's privileges ("administrator", "read-write", or "read-only"), and the user is allowed to gain access to the switch. If the user is not authenticated, then an Authentication Reject is sent to the switch and the user is not allowed access to the switch's embedded management.

The Remote Authentication Dial-In User Service (RADIUS) is an IETF standard (RFC 2138) client/server security protocol. Security and login information is stored in a central location known as the RADIUS server. RADIUS clients, such as the C360, communicate with the RADIUS server to authenticate users.

All transactions between the RADIUS client and server are authenticated through the use of a "shared secret" which is not sent over the network. The shared secret is an authentication password configured on both the RADIUS client and its RADIUS servers. The shared secret is stored as clear text in the client's file on the RADIUS server, and in the non-volatile memory of the C360. In addition, user passwords sent between the client and server are encrypted for increased security.

In the C360, RADIUS is used to authenticate management stations and (independently) for

802.1x port-based access control.

Figure 22

illustrates the RADIUS authentication procedure:

Recovery Password

Introduction to Recovery Password

The C360 provides a recovery password in the event that you have forgotten the login password for the switch. The recovery password feature enables you to login to the device in a super user mode and change the regular login password.

The recovery password feature can be disabled preventing unauthorized user to login to the device using the recovery password. However, if the recovery password feature is disables and you forget the login password, it will not be possible to log in to the switch. By default the recovery password feature is enabled.

To use the recovery password feature, you must connect to the switch's console port. Log in using the user name "root" and password "ggdaseuaimhrke". Use the set username command to change the password for the user "root".

Recovery Password

Tip:

Tip: Enabling and disabling the Recovery Password protocol can only be done using

a direct console connection via the Console port.

Allowed Managers

Allowed Managers Introduction

With the Allowed Managers feature, the network manager can determine who may or may not gain management access to the switch. The feature can be enabled or disabled (default is disabled). When enabled, only those stations that are configured in the Allowed Managers t able are able to gain Telnet, HTTP, and SNMP management access to the switch.

You can configure up to 20 Allowed Managers by adding or removing their IP address from the Allowed Managers List.

Tip:

Tip: The identification of an "Allowed Manager" is done by checking the Source

IP address of the packets. Thus, if the Source IP address is modified on the way (NAT, Proxy, etc.), even an "Allowed Manager" will not be able to access the C360.

Allowed Managers CLI Commands

Uploading and Downloading Device Configurations and Images

The C360 allows you to backup and restore device configurations and configure multiple devices using Simple Network Management Protocol (SNMP) and Trivial File Transfer Protocol (TFTP) or Secure Copy Protocol (SCP) to exchange information with the devices. For more information on SNMP, refer to SNMP Support to SCP Protocol Support

on page 103.

When you make changes to a switch’s configuration, you may find that the overall effect of the configuration change may have a negative effect on the performance of the device in your network. By uploading a switch’s configuration file before any configuration changes, you can easily restore the switch to a previous configuration.

In addition, you can download the same configuration file to multiple devices in the network, resulting in a consistent configuration.

You can also download image files to the switch. The image files provide the switch’s firmware and device manager.

on page 73. For more information on SCP, refer

Tip:

Tip: Only parameters that differ from the factory default settings for the switch are

included in the configuration file. Therefore, it is important to re-initialize the NVRAM to the factory default settings before downloading configuration files to the switch.

The C360 commands for uploading and downloading device configuration files differ for the Layer 2 and Layer 3 configuration files.

Tip:

Tip: To upload or download files, you must log in to the device as a user with

Supervisor level privileges.
