IPv6 management features
NOTE
On 48GC modules in non-jumbo mode, the maximum size of ping packets is 1486 bytes and the
maximum frame size of tagged traffic is no larger than 1581 bytes.
SNTP over IPv6
To enable the Brocade device to send SNTP packets over IPv6, enter the sntp server ipv6 command
at the Global CONFIG level of the CLI.
Brocade(config)#sntp server ipv6 3000::400
Syntax: sntp server ipv6 <ipv6-address>
The <ipv6-address> is the IPv6 address of the SNTP server. When you enter the IPv6 address, you
do not need to specify the prefix length. A prefix length of 128 is implied.
SNMP3 over IPv6
Brocade FastIron devices support IPv6 for SNMP version 3. For more information about how to
configure SNMP, refer to Chapter 10, “SNMP Access”.
Specifying an IPv6 SNMP trap receiver
You can specify an IPv6 host as a trap receiver to ensure that all SNMP traps sent by the device will
go to the same SNMP trap receiver or set of receivers, typically one or more host devices on the
network. To do so, enter a command such as the following.
Brocade(config)#snmp-server host ipv6 2001:efff:89::13
Syntax: snmp-server host ipv6 <ipv6-address>
The <ipv6-address> you specify must be in hexadecimal format using 16-bit values between colons
as documented in RFC 2373.
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” on page 179.
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.
