Using Telnet
ExtremeWare XOS 10.1 Concepts Guide 35
The management port on the MSM is a DTE port. The TCP/IP configuration for the management port
is done using the same syntax as used for VLAN configuration. The VLAN mgmt comes preconfigured
with only the 10/100 UTP management port as a member.
When you configure the IP address for the VLAN mgmt, it gets assigned to the primary MSM. You can
connect to the management port on the primary MSM for any switch configuration. The management
port on the backup MSM is available only when failover occurs. At that time, the primary MSM
relinquishes its role, the backup MSM takes over, and the VLAN mgmt on the new primary MSM
acquires the ipaddress of the previous master.
You can configure the IP address, subnet mask, and default router for the VLAN mgmt, using the
following commands:
configure vlan mgmt ipaddress <ip_address>/<subnet_mask>
configure iproute add default <gateway> {vr <vrname>} {<metric>} {multicast-only |
unicast-only}
Using Telnet
Any workstation with a Telnet facility should be able to communicate with the switch over a TCP/IP
network using VT100 terminal emulation.
Up to eight active Telnet sessions can access the switch concurrently. If
idletimeouts
are enabled, the
Telnet connection will time out after 20 minutes of inactivity. If a connection to a Telnet session is lost
inadvertently, the switch terminates the session within two hours.
Before you can start a Telnet session, you must set up the IP parameters described in “Configuring
Switch IP Parameters” on page 36. Telnet is enabled by default.
NOTE
Maximize the Telnet screen so that automatically updating screens display correctly.
To open the Telnet session, you must specify the IP address of the device that you want to manage.
Check the user manual supplied with the Telnet facility if you are unsure of how to do this.
After the connection is established, you will see the switch prompt and you may log in.
Connecting to Another Host Using Telnet
You can Telnet from the current CLI session to another host using the following command:
telnet [<remote_ip> | <host_name>] {vr <vr_name>} {<port>}
If the TCP port number is not specified, the Telnet session defaults to port 23. If the virtual router name
is not specified, the Telnet session defaults to virtual router VR-0. Only VT100 emulation is supported.
To change the default TCP port number, use the following command:
configure telnet port [<port number> | default]
The range for the port number is 1 through 65535.
