Accessing the switch 7
Management Network
The 1Gb Intelligent L2 Switch is a Switch Module within the Blade Enclosure. The Blade Enclosure includes an
Enclosure Manager Card which manages the modules and CPU Blades in the enclosure.
The 1Gb Intelligent L2 Switch communicates with the Enclosure Manager Card through its internal management
port (port 19). The factory default settings permit management and control access to the switch through the 10/100
Mbps Ethernet port on the Blade Enclosure, or the built-in console port. You also can use the external Ethernet
ports to manage and control this switch.
The switch management network has the following characteristics:
•
Port 19 — Management port 19 has the following configuration:
•
Flow control: both
•
Auto-negotiation
•
Untagged
•
Port VLAN ID (PVID): 4095
•
VLAN 4095 — Management VLAN 4095 isolates management traffic within the switch. VLAN 4095 contains
only one member port (port 19). No other ports can be members of VLAN 4095.
•
Interface 256 — Management interface 256 is associated with VLAN 4095. No other interfaces can be
associated with VLAN 4095. You can configure the IP address of the management interface manually or
through Dynamic Host Control Protocol (DHCP).
•
Gateway 4 — This gateway is the default gateway for the management interface.
•
STG 32 — If the switch is configured to use multiple spanning trees, spanning tree group 32 (STG 32)
contains management VLAN 4095, and no other VLANS are allowed in STG 32. The default status of STG 32
is off.
If the switch is configured to use Rapid Spanning Tree Protocol, STG 1 contains management VLAN 4095.
To access the switch management interface:
•
Use the Enclosure Manager Card internal DHCP server, through Enclosure-Based IP Addressing
•
Assign a static IP interface to the switch management interface
(interface 256).
Connecting through the console port
Using a null modem cable, you can directly connect to the switch through the console port. A console connection is
required in order to configure Telnet or other remote access applications. For more information on establishing
console connectivity to the switch, see the
User’s Guide
.
Connecting through Telnet
By default, Telnet is enabled on the switch. Once the IP parameters are configured, you can access the CLI from
any workstation connected to the network using a Telnet connection. Telnet access provides the same options for a
user and an administrator as those available through the console port, minus certain commands. The switch
supports four concurrent Telnet connections.
To establish a Telnet connection with the switch, run the Telnet program on your workstation and issue the telnet
command, followed by the switch IP address:
telnet <switch IP address>
Connecting through Secure Shell
By default, the Secure Shell (SSH) protocol is disabled on the switch.
SSH enables you to securely log into another
computer over a network to execute commands remotely. As a secure alternative to using Telnet to manage switch
configuration, SSH ensures that all data sent over the network is encrypted and secure. For more information, see
the “Secure Shell and Secure Copy” section later in this chapter. For additional information on the CLI, see the
Command Reference Guide
