IPv6 management (IPv6 host support)
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 3001:2837:3de2:c37::6,
enter the following command.
Brocade#telnet 3001:2837:3de2: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
“Tracing an IPv4 route” on page 96.
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.
For example, to trace the path from the Brocade device to a host with an IPv6 address of
3301:23dd:349e:a384::34, enter the following command:
Brocade#traceroute ipv6 3301:23dd:349e:a384::34
Syntax: traceroute ipv6 <ipv6-address>
The <ipv6-address> parameter specifies the address of a host. You must specify this address in
hexadecimal using 16-bit values between colons as documented in RFC 2373.
