Secure Shell, SCP, and IPv6
Secure Shell (SSH) is a mechanism that allows secure remote access to management functions on the Brocade device. SSH provides a
function similar to Telnet. You can log in to and configure the Brocade device using a publicly or commercially available SSH client
program, just as you can with Telnet. However, unlike Telnet, which provides no security, SSH provides a secure, encrypted connection to
the Brocade device.
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 "SSH2 and
SCP" chapter in the
FastIron Ethernet 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.
To establish a Telnet connection to a remote host with the IPv6 address of 2001:DB8:3de2:c37::6, enter the following command.
device#telnet 2001:DB8:3de2:c37::6
Syntax: telnet ipv6-address [ port-number | outgoing-interface ethernet 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 port | ve number parameter.
This parameter identifies the interface that must be used to reach the remote host. If you specify an Ethernet interface, you must also
specify the port number associated with the interface. 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 FastIron Ethernet Switch
Administration Guide .
The traceroute command allows you to trace a path from the Brocade device to an IPv6 host.
The CLI displays trace route information for each hop as soon as the information is received. Traceroute requests display all responses to
a minimum TTL of 1 second and a maximum TTL of 30 seconds. In addition, if there are multiple equal-cost routes to the destination,
the Brocade device displays up to three responses.
