IPv6 management on Brocade ICX 6650 devices (IPv6 host support)
5
To open an SSH session between an IPv6 host running an SSH client program and the Brocade
device, open the SSH client program and specify the IPv6 address of the device. For more
information about configuring SSH on the Brocade device, refer to the Brocade ICX 6650 Switch
Security Configuration Guide.
IPv6 Telnet
Telnet sessions can be established between a Brocade device to a remote IPv6 host, and from a
remote IPv6 host to the Brocade device using IPv6 addresses.
The telnet command establishes a Telnet connection from a Brocade device to a remote IPv6 host
using the console. Up to five read-access Telnet sessions are supported on the router at one time.
Write-access through Telnet is limited to one session, and only one outgoing Telnet session is
supported on the router at one time. To see the number of open Telnet sessions at any time, enter
the show telnet command.
Example
To establish a Telnet connection to a remote host with the IPv6 address of 2001:DB8::1, enter the
following command.
Brocade#telnet ipv6 2001:DB8::1
Syntax: telnet <ipv6-address> [<port-number> | outgoing-interface ethernet
<stack-unit>/<slot>/<port> | ve <number>]
The <ipv6-address> parameter specifies the address of a remote host. You must specify this
address in hexadecimal using 16-bit values between colons as documented in RFC 2373.
The <port-number> parameter specifies the port number on which the Brocade device establishes
the Telnet connection. You can specify a value between 1 - 65535. If you do not specify a port
number, the Brocade device establishes the Telnet connection on port 23.
If the IPv6 address you specify is a link-local address, you must specify the outgoing-interface
ethernet <stack-unit>/<slot>/<port>| ve <number> parameter. This parameter identifies the
interface that must be used to reach the remote host. Specify the ethernet port in the
<stack-unit>/<slot>/<port> format. Stack-unit is 1. If you specify a VE interface, also specify the VE
number.

Establishing a Telnet session from an IPv6 host

To establish a Telnet session from an IPv6 host to the Brocade device, open your Telnet application
and specify the IPv6 address of the Layer 3 Switch.
IPv6 traceroute
NOTE
This section describes the IPv6 traceroute command. For details about IPv4 traceroute, refer to
“Tracing an IPv4 route” on page71.
The traceroute command allows you to trace a path from the Brocade device to an IPv6 host.
