Managing the Network

Managing the Network


This chapter tells you how to use the network administration commands. Examples of the tasks that these commands perform are creating a password, setting the network date and time, and adding a user.

Signing on to the System

Signing on to a node is a two-step process that requires you to enter a User ID and a password. The system or network administrator can provide a User ID and password to you. The user ID can be up to 12 characters. To protect the security of the system, you should change your password regularly. Only your system administrator can change the User ID. To sign on to a node:


Step 1   Enter your user ID at the system prompt "Enter User ID."

Step 2   Enter your password at the password prompt "Enter Password." For security, the system does not echo the password to the screen. For initial sign-on, enter the password that the system administrator provides. Later, you can change the password with cnfpwd.

After you sign on, the system prompts for the next command. The system is now ready for you to enter commands.

Signing Off the System

When you have completed a session and want to sign off, use the bye command. This returns the display to the initial system sign-on prompt. If you enter the bye command when you have a virtual terminal connection to another node, the bye command ends the virtual terminal connection and establishes a local connection. To end the local connection, enter the bye command again.

Creating a New Password

To change the password, takes the step in the list that follows. given to you by your System Administrator, or to change your present password to a different one, perform the following. To ensure the security of your system, your password should be changed on a regular basis. See the System Administrator for the recommended frequency of change.


Step 1   Enter the cnfpwd command. The system prompts for your current password.

Step 2   Enter your current password. The system prompts for a new password.

Step 3   Enter a new password. Passwords must have 6-15 characters. The system prompts you to confirm the new password by typing it again.

Set Date and Time

Date and time are network-wide parameters. You can set Timezone for each node. The cnfdate command lets you set both time and date. The cnftime command lets you set.

adduser

Adds a user to the network. The first time the new user ID is used for logon, a prompt appears asking the user to change from the default password to a new password which they enter using the cnfpwd command. Users with privilege levels 1 through 5 may add users with lower privilege levels. Since privilege level 6 has no user levels below it, level 6 cannot add any users.

Table 15-2: adduser—Parameters
Parameter Description

userid

Specifies the name of the user to add.

privilege level

Specifies the privilege level to grant to the added user. The range of levels is 1-6, where 1 is the highest level and 6 is the lowest.

cnfdate

Sets date and time for the entire network. The node broadcasts the specified date and time to every node in the network. The time displayed at each node is consistent with the time zone where the node resides. (See cnftmzn.) For the first-time configuration of the date and time in a new network, cnftdate requires all the parameters except for [sec]. The default for [sec] is 0. If a date and time already exist in the network, the defaults are the existing values at the moment you enter the cnftdate command. Note that changes to date and time alter the timestamps on StrataView statistics.

"Warning: Changing time of day affects StrataView statistics timestamps

Continue?"
Enter "y" to continue or "n" to abort." Upon a "y" response, the system further prompts with: "Hit RETURN to change clock, DEL to abort."

month

Specifies the month. The range is 1 - 12.

day

Specifies the day. The range depends on the month and can be 0 - 31.

hour

Specifies the hours. The range is 0 - 23. For example, enter 6 AM as 6 and 6 PM as 18.

min

Table 15-4: cnfdate—Optional Parameters
Parameter Description

sec

cnfpwd

Changes the password associated with a UserID. To change a password, you must log into the node with the UserID whose password you want to change. Passwords are case-sensitive.

In a structured network, each domain requires you to have a password. In each domain, your password and associated privilege level can be the same of different from those in the other domains. For each domain, you can change the password at any node within the domain, including a junction node.

cnfstatmast

Configures an IP address for the Statistics Master process in StrataView Plus. The cnfstatmast command defines the IP address for routing the messages to and from the Statistics Master in StrataView Plus.

The Statistics Master process requests and receives network statistics by using TFTP Get and Put messages. These TFTP messages pass between the node and the Statistics Master over IP Relay. See the cnfnwip description for details on setting a node address.

Parameter Description

ip address

Specifies the IP address for the Statistics Master. IP addresses have 32-bits. The format of an IP address is x.x.x.x, where x is a value in the range 1 - 255.

cnfsysparm

Configures the system (network-wide) parameters.


Note Using cnfsysparm requires caution because network rerouting or loss of data may result from changes in system parameters. If necessary, consult with the Cisco TAC before you use this command.

The following paragraphs describe the user-configurable system parameters. The table that follows this list shows the system parameters, their default values, and their ranges. The numbers in the following paragraphs are the index numbers in the table.

This command sets system parameter values for all nodes in the network. Network-wide parameters are configurable only when all nodes in the network are reachable. Be aware of the consequences of the resolution of conflicting values when networks are joined. Table 15-8 lists the system parameters, their default values, and their ranges. The summary, examples, and parameter summary then follows.

When the following prompt appears on the screen:

  Which parameter do you wish to change:

Enter the number of the parameter you wish to change, along with the value. For example, to change the Maximum Time-Stamped Packet Age (1) from 40 msecs to 42 msecs, enter:

  1 42

When you configure this parameter, the second screen does not change. However, if you change item 15, the following prompt appears on the screen:

  Changing this parameter will reset Frame Relay classes to their defaults. Continue (y/n)?

Changing parameter 15 requires a change in the Frame Relay classes. Since Frame Relay classes are not associated with a specific port (or port speed 0), no translation can be made. The values for Bc and Be, or VC Q depth and PIR are reset to their default values.
