IPv6 management on Brocade ICX 6650 devices (IPv6 host support) 5

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.

Brocade(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.

Brocade(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 ICX 6650 devices support IPv6 for SNMP version 3. For more information about how to configure SNMP, refer to Chapter 6, “SNMP Access”.

Configuring SNTP over IPv6

To enable the Brocade device to send SNTP packets over IPv6, enter a command such as the following at the Global CONFIG level of the CLI.

Brocade(config)#sntp server ipv6 2001:DB8::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.

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.
