Connecting To Another Host Using Telnet; Configuring Switch Ip Parameters - Extreme Networks ExtremeWare XOS Guide Manual

For information about the Telnet server on the switch, see the following sections:

Connecting to Another Host Using Telnet

You can Telnet from the current CLI session to another host using the following command:
telnet {vr <vr_name>} [<host_name> | <remote_ip>] {<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 VR-Mgmt. Only VT100 emulation is supported.

Configuring Switch IP Parameters

To manage the switch by way of a Telnet connection or by using an SNMP Network Manager, you must
first configure the switch IP parameters.
Using a BOOTP or DHCP Server
If you are using IP and you have a Bootstrap Protocol (BOOTP) server set up correctly on your network,
you must provide the following information to the BOOTP server:
Switch Media Access Control (MAC) address, found on the rear label of the switch
●
IP address
●
Subnet address mask (optional)
●
The switch contains a Bootstrap Protocol (BOOTP) and Dynamic Host Configuration Protocol (DHCP)
client, so if you have a BOOTP or DHCP server in your IP network, you can have it assign IP addresses
to the switch. This is more likely to be desirable on the switch's VLAN mgmt than it is on any other
VLANs.
You can enable the BOOTP or DHCP client per VLAN by using the following commands:
enable bootp vlan [<vlan> | all]
enable dhcp vlan [<vlan_name> | all]
You can disable the BOOTP or DHCP client per VLAN by using the following commands:
disable bootp vlan [<vlan> | all]
disable dhcp vlan [<vlan_name> | all]
To view the current state of the BOOTP or DHCP client, use the following command:
show dhcp-client state
The switch does not retain IP addresses assigned by BOOTP or DHCP through a power cycle, even if
the configuration has been saved. To retain the IP address through a power cycle, you must configure
the IP address of the VLAN using the CLI or Telnet.
If you need the switch's MAC address to configure your BOOTP or DHCP server, you can find it on the
rear label of the switch. Note that all VLANs configured to use BOOTP or DHCP use the same MAC
