Configuring the Management Interface

Configuring the management interface consists of tasks for setting the system name, IP address and mask, gateway, and DNS servers. Use the following procedure to configure the management interface.

 
Command
Description

Step 1 

enable

Enter Administrator mode.

Step 2 

hostname SN_5420-MG1

Specify or change the system name. The system name identifies the SN 5420 through the management interface and appears immediately in the prompt.

Step 3 

interface mgmt ip-address 10.1.10.244/24

Specify or change the IP address and subnet mask for the management interface.

Note If this storage router is to participate in a cluster, the management interface for all storage routers in the cluster must be on the same IP subnet.

Step 4 

ip route 10.1.30.0/24 10.1.10.201

(Optional) Configure a gateway IP address if the storage router is to be managed from a management station outside the storage router management subnet. The second IP address specifies a gateway on the storage router management network that will provide access to a management station.

Note In this configuration example, the mask is set to 24 (255.255.255.0) to allow any host on subnet 10.1.30.0 to be a management station.

Step 5 

ip name-server 10.1.40.243 10.1.50.249

(Optional) Set the primary and secondary DNS IP addresses. Specifies the IP address of the primary DNS server if the management interface IP address is to be correlated with a DNS host name. If there is a secondary DNS, the second IP address specifies the IP address of the secondary DNS server.

Step 6 

ip domain-name mystoragenet.com

(Optional) Specify the domain name of the storage router. Use this command in conjunction with the ip name-server command.

Step 7 

ip route 10.1.40.243/32 10.1.10.201

(Optional) Configure a gateway IP address if the primary DNS server is outside the storage router management subnet. The second IP address specifies a gateway on the storage router management network that will provide access to a primary DNS server.

Note In this configuration example, the mask is set to 32 (255.255.255.255) to specify the host with IP address 10.1.40.243 (the primary DNS server).

Step 8 

ip route 10.1.50.249/32 10.1.10.201

(Optional) Configure a gateway IP address if the secondary DNS server is outside the storage router management subnet. The second IP address specifies a gateway on the storage router management network that will provide access to a secondary DNS server.

Note In this configuration example, the mask is set to 32 (255.255.255.255) to specify the host with IP address 10.1.50.249 (the secondary DNS server).

Configuring Time and Date

Configuring time and date parameters consists of specifying the time, date, time zone, and time server. Use the following procedure to configure the time and date parameters.

 
Command
Description

Step 1 

enable

Enter Administrator mode.

Step 2 

clock set 08:20:00 02 15 2002

Set time and date (for example: time, 8:20 a.m.; date, February 15, 2002).

Step 3 

clock timezone US/Pacific

Identify the time zone where the storage router is located. If a time zone is not identified, time is assumed to be GMT.

Note To use the clock timezone command, you must use a valid time-zone string. For a list of valid time-zone strings, use the clock timezone ? command. See "Command Line Interface Reference," for details.

Step 4 

ntp peer 10.1.60.86

(Optional) Specify the name or IP address of the network time protocol (NTP) server with which the storage router will synchronize the date and time.

Step 5 

ip route 10.1.60.86/32 10.1.10.201

(Optional) Specify the gateway IP address if the time server is outside the storage router management subnet. The second IP address specifies the gateway on the storage router management network that provides access to the time server.

Note In this configuration example, the mask is set to 32 (255.255.255.255) to specify the host with IP address 10.1.60.86.

Configuring Network Management Access

Configuring network management access consists of tasks for configuring SNMP. Use the following procedure to configure SNMP for network management access.

 
Command
Description

Step 1 

enable

Enter Administrator mode.

Step 2 

no restrict all telnet

(Optional) Enable Telnet access on all interfaces. By default, Telnet access is enabled on only the management interface.

Step 3 

snmp-server community world ro

(Optional) Specify the name of the community having read-only access of the storage router network (that is, to which community's GET commands the storage router will respond). The default read community is public.

Step 4 

snmp-server community mynetmanagers rw

(Optional) Specify the name of the community having write access to the storage router network (that is, to which community's SET commands the storage router will respond). The default write community is private.

Step 5 

snmp-server host 10.1.30.17 version 2 traps

Specify the IP address for the first destination host used for a specified version of notifications (traps). Version 1 traps is the default version.

Note In this configuration example, the trap hosts have IP addresses that are outside the storage router management subnet. In an earlier step in the Configuring the Management Interface section, a gateway was already specified providing access to hosts on the 10.1.30.0 subnet.

Step 6 

snmp-server host 10.1.30.18 traps

(Optional) Specify the IP address for the second destination host used for notifications (traps). Version 1 traps is the default version.

Step 7 

snmp-server sendauthtraps

(Optional) Enable sending of authentication failure traps.

Step 8 

no snmp-server linkupdown all

(Optional) By default, the SNMP agent is enabled to generate link up/down traps for all interfaces. In this configuration example, the command disables this setting for all interfaces. To disable this setting for individual interfaces, see "Command Line Interface Reference."

Configuring Passwords

Configuring passwords consists of setting the Monitor-mode and Administrator-mode passwords for access to the 10/100 Ethernet management interface (used for the CLI via Telnet and the web-based GUI via HTTP). You can enable these passwords to restrict access to the RS-232 console interface. Use the following procedure to configure passwords.


Note The factory default password for both Monitor and Administrator modes is cisco.


 
Command
Description

Step 1 

enable

Enter Administrator mode.

Step 2 

monitor password janu$01

Set the monitor password (for users who only monitor storage router operation).

Step 3 

admin password electr@50

Set the administrator password (for system administrators, allowing configuration changes).

Step 4 

restrict console

(Optional) Enable the Monitor-mode and Administrator-mode passwords to be required when accessing the SN 5420 via a console connected to the RS-232 console interface.

Configuring Administrator Contact Information

Configuring administrator contact information consists of tasks for specifying the name, e-mail address, phone number, and pager number of the system administrator for the storage router. Use the following procedure to configure administrator contact information.

 
Command
Description

Step 1 

enable

Enter Administrator mode.

Step 2 

admin contactinfo name "Pat J. Smith" email pjsmith@mystoragenet.com phone "763 555-1117" pager "763 555-7766"

Provide contact name, e-mail address, phone number, and pager number. Enclose each string that contain spaces in single or double quotes.

Note The admin contactinfo command requires that you specify either one parameter or all four parameters.

Configuring the High-Availability (HA) Interface

When the storage router is part of a storage router cluster, you will need to configure the high availability (HA) interface. Use the following procedure to configure the HA interface parameters.


Note The high-availability service is only available with SCSI routing. It is not available if the SN 5420 is configured for transparent SCSI routing or iSCSI SAN interconnect.



Note A maximum of four SN 5420 Storage Routers can be configured in a cluster.


 
Command
Description

Step 1 

enable

Enter Administrator mode.

Step 2 

show cluster

Display cluster information and refer to the HA Configuration field to verify if the storage router is running as standalone or clustered. Also, verify if the HA interface is configured with a correct IP address.

Step 3 

setup cluster

Run the setup cluster wizard. The wizard prompts you to do the following:

Select the appropriate HA configuration mode (standalone or clustered).

Specify HA interface IP address and subnet mask
(The HA and management interfaces must not be on the same network; each interface must be on a unique IP network. In a cluster, the HA interfaces for all storage routers must be on the same IP subnet.)

Change cluster name (if necessary).

You will be asked if you want to retain or delete the current configuration of the storage router:

Retaining means that the configuration of this storage router (including SCSI routing instances) is propagated to other storage routers in the same cluster.

Deleting means that the existing configuration (including SCSI routing instances) will be deleted from the storage router.

If you are joining an existing cluster, any access lists that you have previously defined will be overwritten by the access lists available to the cluster. This occurs regardless of your decision to retain or delete configuration information. If you wish to make your current access lists available to the cluster, you must save them to a file before joining the cluster, then restore them. See "Configuring a Storage Router Cluster" for complete details.

As prompted, type yes to confirm your choice to retain or delete the current configuration of the SN 5420. The system will then automatically reboot.

Verifying and Saving Configuration

Verify the system parameters using the following procedure. You can save the configuration at any time using either the save system bootconfig or save all bootconfig commands. You must save the running configuration to the bootable configuration for it to be retained in the storage router when it is rebooted.

Use the following procedure to verify configuration information.

 
Command
Description

Step 1 

enable

Enter Administrator mode.

Step 2 

show system

Display system information, such as system name, system deployment, software version, date and time (including time zone), NTP server, DNS (name server), and management and HA interface IP addresses.

Step 3 

show ip route

(Optional) Display the system route table, if you added any routing information.

Step 4 

show snmp

(Optional) Display SNMP management configuration information for the storage router, if set.

Step 5 

show admin

(Optional) Display contact information for the system administrator of the storage router, if set.

Step 6 

show cluster

(Optional) Display cluster name and other cluster information, if you configured the storage router as a member of a cluster.
