Restricting SNMP access to an IPv6 node
You can restrict SNMP access to the device to the IPv6 host whose IP address you specify. To do so,
enter a command such as the following.
device(config)#snmp-client ipv6 2001:DB8:89::23
Syntax: snmp-client ipv6 ipv6-address
The ipv6-address you specify must be in hexadecimal format using 16-bit values between colons as
documented in RFC 2373.
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.
device(config)#snmp-server host ipv6 2001:DB8:89::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.
Configuring SNMP V3 over IPv6
Brocade FastIron X Series, FCX, and ICX devices support IPv6 for SNMP version 3. For more
information about how to configure SNMP, refer to FastIron Ethernet Switch Security Configuration
Guide .
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.
